MANTED: Guidelines-Interfaces TG

1. Areas of Application

This description of an interface will be useful to all vehicle body constructors who need an “external engine speed control system” on a MAN-commercial vehicle. The interface described here supplements and extends the standard “ZDR-Interface with FFR” and provides a much wider range of functions. Via the CAN interface of the KSM (A-CAN) it is possible to set up the Fleet Management System Interface (FMS-Interface). The interface implementation described here refers to the “Trucknology Generation” (TG) range of vehicles.

5.     General Observations on the ZDR Interface With KSM

•    The interface is not included in the standard vehicle delivery specification and must be ordered separately.
•   The desired parameters in the KSM control unit such as engine speed limiting, torque limiting etc. must be notified to the MAN
     sales team when placing the order. This information is passed on for factory programming.
•   Preparation for the “Start-stop device” set-up is independent of the external engine speed control system interface and must
     be ordered separately.
    The attachment necessary for external “Engine start-stop” control is supplied rolled up in the cable harness at the rear end
     of the frame.
•   “Accidental reversing prevention” for garbage collection vehicles is not included in the interface and must be ordered separately.
•   Extreme care is necessary when wiring up the interface. This activity is critical because it involves actions
     that fundamentally affect the on board network and the wiring for the electronics.
•   Only use suitable electric wiring that conforms to MAN standard M 3135.
•   Use only relays that meet the requirements set out in the MAN relay specification for external circuits.
•   Make absolutely sure that wires are crimped strictly according to makers’ instructions.
•   Any external controls incorporated by the constructor must meet enclosure standards according to IP69K DIN 40 050 and
     in addition be secure against external tampering.
•   The power supply (+U_BAT) for body equipment and control units incorporated by the constructor must be led from the batteries
     via a suitable separate circuit protection device or fuse. It is not permissible to take off more than 12 volts from a single battery.
•   A separate cable must be used for electrical earthing and connected to the common earth point on the engine mounting
     (never use the vehicle frame as an earth conductor).
•   Do not link together several items of externally switched equipment with different earth potentials.
•   Circuits at the interface must be decoupled from the power supply circuit to the body control systems.
•   External switching systems must meet the demands of MAN standard M 3285 for commercial vehicle systems. For example, radio
     systems such as radio-operated remote control devices must not have any effect on the functions described in this MAN standard.
•   Diagrams and pictures supplied by MAN to illustrate and provide examples of electrical circuits are not to be regarded as
     specific assembly instructions. The responsibility for the circuits at the interface rests entirely with the party carrying out the work.
•   Changes to the functionalities of the interface as set in the factory can be made at MAN service centres or by MAN authorized
     dealers. This requires the use of the MAN-cats II service computer. The MAN-cats experts in the workshops can order additional
     system solutions from the factory which go beyond those provided on the service computer (e.g. for special cases). For this
     purpose, department ESC has made available the service “Vehicle Parameter Setting Ex Works” in order to assist the workshops.

6.     Notes on setting up the Parameters for the KSM

6.1.     Fundamental functions regulating intermediate engine speed settings

•    Setting of individual ZDR parameters is carried out in the FFR. Individual modes can be selected externally
    (outside the driver’s cabin) if required via the standard ZDR interface(FFR).
•   Possible parameters and also the PIN description of the “ZDR-interface with FFR” are described in the document “ZDR-interface
    with vehicle management computer for external intermediate engine speed control on the TG (Trucknology Generation) range”.
•   Using the “ZDR-interface with KSM”, the functions “SET+”, “SET-”, “MEMORY” and “OFF/AUS” (familiar from the cruise control)
    are available for external use outside the driver’s cabin.
•   Additionally other intermediate engine speeds can be obtained by activating an engine speed limiter.

6.2.     Possibilities for setting parameters on the KSM

Parameters for various functions can be set on the KSM using MAN-cats II:

•   Engine speed and torque limiting:
    Activating the DrzMomBgr pins (X1997/Pin 1 and 2) permits selection of the engine speed and torque limit parameters.

Factory settings:

•    Parameter selection matrix for switching outputs.
    A total of 5 high side switching signal outputs (Hs1_ konfig…Hs5_ konfig) and 3 low side switching signal outputs (Ls1_konfig,…
    Ls3_konfig) are available. The following table shows the signals/functions with which the total of 8 switching signal outputs
    (5 x high side and 3 x low side) can be set up as required. It is also possible to arrange for several switching signals to initiate
     the same signal/function.

•   With fault recognition
            Þ Monitoring high-side switches:
                Signal high: Short circuit to earth is monitored
                Signal low: Short circuit +U_BAT and open circuit are monitored
            Þ Monitoring low-side switch:
                 Signal high: Short circuit to earth and open circuit are monitored
                 Signal low: Short circuit to +U_BAT is monitored
•   With fault recognition and test pulses (“extended fault recognition”)
             Þ Test pulses during KSM system start (up to approx. 3 sec after “terminal 15 on”)
                 During the system start, short circuits to +U_BAT , short circuits to earth, and open circuits are monitored,
                 and thereafter fault recognition is carried out according to the switch signal output version.
             Þ Test pulses
                  Irrespective of the switch signal output version, after “terminal 15 on”, short circuits to +U_BAT,
                  short circuits to earth and open circuits are monitored.
Preconditions for fault recognition:
The load at the output on high-side switches must not be larger than 400 Ω and for low-side switches no larger than 2000 Ω.

Note:
By activating the fault recognition, the depth of diagnosis for the components connected to the “ZDR interface with KSM”
is considerably improved, with a consequent increase in functional reliability and vehicle availability.

For example, the recognition of faults on the output Hs3_konfig-delegt with signal R-gear is prevented according to the set parameters:

•   Output not supported (load is connected):
    Fault recognition not active [fault recognition “zero”]

•    Output supported (load must be connected!):
Fault recognition active: present status of output is being monitored [fault recognition “1”]

•    Output supported (load must be connected!):
    Fault recognition active: present status of output is being monitored and test pulses are only produced during start-up of KSM
    (checking of short circuits to earth negative for high-side switches and checking of U_BAT- short circuits
    for low-side switches [fault recognition “2”]

•  Output supported (load must be connected!):
      Fault recognition active: present status of output is being monitored and test impulses are cyclical
     (permanent monitoring of short circuits to earth for high-side switches and permanent monitoring
     of U_BAT short circuits for low-side switches [fault recognition “3”]

Note:
Test pulses have a duration of approx. 1ms and a repeat interval of approx. 300ms.

“ Fail safe” operation of signal outputs
     For various signals, parameters can be set in order to control how the corresponding switch signal
     output operates in the event of a fault. If the driver is energised, the reaction can be parametered to allow
     for the case of unknown/defective information

(CAN failure/signal (sensor) failure):

•   “Do not freeze” signal
     The driver which is parametered for this signal (Hs1 konfig…Hs5 konfig…Ls1 konfig…Ls3 konfig)
      changes from the active energised status to the passive status in the case of CAN failure/signal (sensor) failure.

•   “Freeze” signal
     The driver parametered for the signal (Hs1 konfig…Hs5 konfig…Ls1 konfig…Ls3 konfig) is frozen in the active energised status,
      if there is a CAN failure/signal (sensor) failure, until a valid signal is present again. After a “terminal 15 reset” and a continuing
      CAN failure/signal (sensor) failure, the driver remains passive.
      This parameter facility avoids an undesired reaction (release/blocking/switching off of equipment etc) for components connected
      to the interface, due to the occurrence of a CAN failure/signal (sensor) failure.

As an example of the parameter setting for “ fail-safe” operation on output Hs1_konfig -occupied by the handbrake signal - the following is shown, depending on the parameters:

•   Handbrake “do not freeze” signal:
    Output Hs_konfig changes to the passive state in the case of CAN/signal (sensor) failure

•      Handbrake “freeze” signal:
    Output stays active in the address status in the case of CAN/signal (sensor) failure

• Evaluation of the request for digital inputs/A-CAN
• ZDR operation:
Parameters can be set which determine whether the inputs (set+/-, MEMORY OFF) are supported. If the inputs are supported,
a corresponding instruction from the A-CAN will be ignored. If the inputs are not supported, an instruction from the A-CAN will be
relayed and possible connections from the digital inputs will be ignored.

Factory settings:

• Clutch released/ext. gearbox N request:
Parameters can be set determining whether this input is supported. If the input is supported, any corresponding instruction from

from the digital input will be ignored.

Factory settings:

• Converter lockup clutch (WSK) open/up-shift interlock:
Parameters can be set as to whether these inputs are supported. If the inputs are supported, any corresponding instruction from

connection from the digital inputs will be ignored.

Factory settings:

	Digital inputs	A-CAN request

• NA-ZDR connection:
For each power take-off (NA1, NA2, NMV) any ZDR mode can be ascribed. The ZDR request is created when a feedback signal is present (for NA1 and NA2). For NMV, the ZDR request is created by a feedback signal or an NMV request (parameter).
The ZDR mode which is allocated to the power take-offs is only processed when the parameter is set at “evaluate” (see table, page 15).
If several power take-offs are activated at the same time, the resulting ZDR mode is created from the association of the values set as parameters, as though the corresponding ZDR pins were activated on the VMC (FFR) interface. The request for a ZDR mode via the KSM has precedence over possible connections from the ZDR pins on VMC module X1996.

7.      A-CAN Interface with FMS Interface

7.1.     General points

For communication purposes the A-CAN (body constructors’ CAN) offers a High-Speed CAN-interface ISO 11898-24V and specification 2.0B. The data transmission speed is 250kbit/s. To protect the MAN CAN-integrated net system on the vehicle against external interference/influences, the CAN is fully galvanically separated.
A 120Ω terminal resistor is included in the KSM as A-CAN bus termination; a CAN filter choke is also provided. The CAN-data communication lead is a 2-wire twisted lead running up to the interface (MAN part number: 07.08132.4384). The lead from the interface to the body-side control unit (e.g. telematics module) should be as short as possible – for electromagnetic reasons – and must be in twisted form (see ISO 11898-24V). Here too, use leads with MAN article number 07.08132.4384.
For this MAN recommends leads with MAN article number 07.08132.4384 (FLRY-2x0.75-B-28-or-bror).

Important:
Untwisting of the CAN leads must be avoided at all costs, in order to exclude electromagnetic influences which could interfere with the operation of the CAN bus.If it is not possible to avoid untwisting, for example at a plug connection, the untwisted part of the lead should be kept as short as possible.

MAN’s definition of the A-CAN is based on SAE J1939/ff.
The identification numbers in brackets relate to SAE J1939/71 “VEHICLE APPLICATION LAYER”. Implementation of the FMS interface is based on the “FMS-standard interface” jointly specified by several European truck manufacturers (www.fms-standard.com).

7.2.     Setting parameters for the A-CAN

•     Every message which the KSM receives on the T-CAN can also be sent to the A-CAN.
•   By means of MAN-cats II, parameters can be set for every A-CAN message received (KSM1_A, KSM2_A), causing them to be either ignored or further processed by the KSM.

Factory setting:

Message::	"not received"	"received"
KSM1_A:	X
KSM2_A:	X

•     Parameters can also be set for the reception time-out, and if required, for the identifier of the received message as well.
•   Using MAN-cats II, parameters can be set for both received messages to provide a “dead time” starting with terminal 15 “on”.
    The actual time-out monitoring of the messages from the body electronics to the KSM will only start upon expiry of this period.
    By this means it is possible to make an adjustment to the KSM to allow for the possible “run-up time” of the body electronic equipment,
    without it being necessary to extend the actual time-out monitoring period for the KSM received messages (KSM1_A, KSM2_A).

Factory setting:

Dead time start time-out recognition KSM1_A	5000ms
Dead time start time-out recognition KSM2_A	5000ms

7.3. Information on vehicle operating status on the A-CAN

Depending on the amount of equipment on the vehicle and the parameters set in the KSM, it is possible to make available the following information from the body electronic equipment via the A-CAN:

Note:
x = message to be sent to the A-CAN
Bold = messages included in the “FMS standard interface” specification
ERC1_RE is only sent if a primary retarder is installed; ERC1_RB is only sent if a secondary retarder is installed.
The signals which are available for the CAN messages are stated in Chapter 7.5.

Important:
When the KSM is configured with function parameter 81.25816.1111 (FMS without KSM functionality),
this only prepares the FMS interface - the usual KSM functions (output of switching signals,
carrying out engine intervention functions (limiting engine speed/torque/demands etc.)) are not available.

7.4.      Possible requests to the KSM via the A-CAN

The KSM can accept on the A-CAN the following requests from the body electronic equipment
for further processing by the KSM/FFR:

•   Torque request/torque limiting
•   Engine speed request/rev limiting
•   Request for intermediate engine speed controller ZDR mode S, 1-7
•   Request for ZDR operation (SET+/-, MEM, OFF)
•   Maximum speed limiting
•   External engine start/stop (on engines with inline injection pumps [EDC MS6.1] only engine stop is possible;
    on common rail engines [EDC7] engine start and stop are possible.
•   NMV demand
•   External neutral demand for gearboxes with automated gear shift and automatic transmissions
•   Demand: WSK open/blocking of up-shift for HP transmissions (ECOMAT)

7.5.     A-CAN output messages

The following output messages can be prepared by the KSM on the A-CAN:

7.7.   Information processing in KSM/VMC as specified by KSM1_A-message

The “override control mode” (OCM) in the KSM1_A message (ASM1_A_OCM) is of great importance for processing engine speed and torque. At the same time the engine speed and torque values in the ASM1_A message are checked for validity. The following description (cases 1-4) describes how the corresponding KSM1_OCM is generated from the KSM1_A_OCM. KSM1 is the T-CAN message from the KSM to the VMC (FFR). In the standard situation the KSM supports the OCM=11 (speed/torque limit control) of the KSM1 message. Processing of the modes OCM=01 (speed control) and OCM=10 (torque control) from the KSM1 message is not activated in the VMC, but if required can be switched on within the VMC.

1. KSM1_A_ocm=11 → KSM1_ocm=11 11 (Speed/torque limit control) at n < 8031,875 rpm or m < 100%
    otherwise KSM1_A_OCM = 00 (disabled)
  •   The limits (KSM1_A) are linked with the digital inputs (torque and engine speed) in such a way that the smallest value in each
       case is used as the KSM1 message.
  •   Demand ZDR S, 1-7 is relayed via the KSM1:
      Activation in the VMC (FFR) depends on the switching conditions that have been set as parameters in the VMC.
  •   A demand for ZDR operating input (SET +/-, MEM, OFF) via KSM1_A or digital inputs KSM - depending on the KSM
      parameters - is relayed via KSM1 and implemented within the VMC.

2. KSM1_A_ocm=01 → KSM1_ocm= 01 (speed control) at n < 8031,875 rpm, otherwise KSM1_A_OCM = 00 (disabled) or 11
  •   The definition of the engine speed target value is only possible with a valid value in KSM1_A (n<=8031, 875 rpm).
       Limiting in KSM1 is possible by means of the KSM digital engine speed/torque limit inputs.
  •   Torque limiting (KSM1_A) is linked with the digital “engine speed/torque limiting” inputs in such a way that in each case the lowest
       value is used as the KSM1 message.

3. KSM1_A_ocm=10 → KSM1_ocm=10 (torque control) at m < =100%, otherwise KSM1_A_OCM = 00 (disabled) or 11
  •   Definition of the torque target value is only possible for a valid value in KSM1_A
      (m < =100%); limiting in KSM1 is possible through digital KSM engine speed/torque limiting inputs.
  •   Engine speed limiting (KSM1_A) is linked with the digital “engine speed/torque limiting” inputs in such a way that
     in each case the lowest value is used as the KSM1 message.

4. KSM1_A_ocm=00 → KSM1_ocm=11 (speed/torque limit control) on activation of digital inputs,
    otherwise KSM1_A_OCM = 00 (disabled)
  •   No processing/ relaying of KSM1_A/Byte 2,3,4.
  •   Engine speed/torque limits via digital “engine speed/torque limiting” inputs possible at KSM.
  •   Demand ZDR S, 1-7 is relayed via KSM 1. Activation in the VMC (FFR) depends on the switching
      set as parameters in the VMC.
  •   A request for ZDR operating input (SET +/-, MEM, OFF) via KSM1_A or digital KSM inputs - depending on the KSM
       parameters - is relayed via KSM1: implementation is within the VMC.

The following applies in all cases:

•   Choice of ZDR mode via CAN has priority over ZDR pins on the VMC.
•   Limits are so linked within the KSM and the VMC that the lowest value is chosen as the KSM1 message.
•   Set target values are restricted to limits.

Note:
If an input value from the A-CAN (A-CAN bus off, KSM1_A failure message) is invalid, the limits (engine speed/torque/maximum speed) are frozen until the A-CAN is available again or until valid values are present (for example: the previously requested limits are frozen, or until terminal 15 “Reset”).

If at the time of the failure of the A-CAN (A-CAN Bus off, failure of KSM1_A message) there is a valid demand for an engine speed or torque value (KSM1_A_OCM = 01/10), the engine reverts to idling speed; if in addition there is a valid limit for engine speed or torque, this value is frozen until the A-CAN is available again or until valid values are present (alternatively until terminal 15 “Reset”).

If at the time of the failure of the A-CAN (A-CAN Bus off failure KSM2_A message) there is a request for ZDR mode (KSM1_A_OCM = 00/11), the engine reverts to idling speed until the A-CAN is available again or until valid values are present (alternatively until terminal 15 “Reset”).

If at the time of the failure of the A-CAN (A-CAN Bus off failure KSM2_A message) there is a demand for ZDR operating input (SET +/SET-, MEM, OFF) (KSM1_A_OCM = 00/11), the present engine speed is maintained until the A-CAN is available again or until valid values are present (alternatively until terminal 15 “Reset”).

If at the time of the failure of the A-CAN (A-CAN Bus off failure KSM2_A message) there is an NMV demand (KSM1_A_OCM = 01/10), this is frozen until the A-CAN is available again or until valid values are present (alternatively until terminal 15 “Reset”).

If at the time of the failure of the A-CAN (A-CAN Bus off failure KSM2_A message) there is a NMV demand for Clutch open/ external gearbox N or converter lockup clutch open, these are also frozen until the A-CAN is available again or until valid values are present (alternatively until terminal 15 “Reset”).

8.     Pin Description and Circuit Diagrams

DrzMomBgr 1+3 (Plug connection X1997/Pin 1)

+U_Bat -switching signal input for activating engine speed/torque limiting 1 and 3.

Function:
If the input is connected to +U_Bat (operating readiness; X1997 Pin12) the engine is limited to “Engine speed/torque limiting 1” for which the parameters can be set via MAN-cats II.

If +U_Bat is removed, the chosen “Engine speed/torque limiting 1” is cancelled again. If at the same time the DRZMomBgr 2+3 input (X1997/Pin2) is connected along with +U_Bat (operating readiness: X1997/PIN12), the engine is limited to “Engine speed/torque limiting 3”, the parameters for which can be set via MAN-cats II.

If +U_Bat is removed from both inputs, the selected “Engine speed/torque limiting 3” is cancelled again.
This function can also be used as another intermediate engine speed control by setting a higher engine speed limit with it initially.

Functional enablement:
As soon as +U_Bat (operating readiness or terminal 15) is present.

Factory settings:

See table for DRZMomBgr 2+3 (plug connector X1997/Pin2).

DrzMomBgr 2+3 (Plug connection X1997/Pin 2)

If the input is connected to +U_Bat (Operating readiness: X1997/PIN12) the engine speed rises continuously towards the upper rev limit; if activation is interrupted, the engine management regulates engine speed value to the value reached at that moment.

The upper engine speed limit can be:
•   The engine’s maximum speed limit
•   The upper engine speed limit for ZDR S, ZDR1, …ZDR7 for which the parameters can be set by means of MAN-cats II
•   Any engine speed limit which was activated and for which parameters have been set in the VMC or KSM by means of MAN-cats II.
The set engine speed value is cancelled, i.e. the engine reverts to idling speed (ZDR S) or the “lower engine speed limit” (ZDR1, …ZDR7) by means of the “open” command for the standard bridge between “Operating readiness” (X1997/PIN12) and “OFF” (X1997/PIN15).

Function enablement:
As soon as the engine is running, the function can be activated by connecting with +U_Bat (Operating readiness or terminal 15).

Important:The implementation of SET+/SET- via the KSM interface is only possible in the ZDR modes for which the condition “Steering column lever active” is set. Ensure that the steering column lever is secured against undesirable interference within the driver’s cab during operation, for example via an external remote control.

SET- (Plug connection X1997/Pin 14)

+U_Bat -switch signal input for activation of the function “Decrease engine speed”.

Function:
Decreases engine speed.
If the input is connected to +U_Bat (Operating readiness: X1997/PIN12) the engine speed setting decreases continuously towards the idle speed setting (ZDR S) or the lower engine speed limit (ZDR1, …ZDR7 ). If activation is interrupted, the engine management regulates engine speed value to the value reached at that moment.
The set engine speed value is cancelled, i.e. the engine goes to the idling speed (ZDR S) or the “lower engine speed limit” (ZDR1, …ZDR7) by means of the “open” command for the standard bridge between “Operating readiness” (X1997/PIN12) and “OFF” (X1997/PIN15).

Function enablement:
As soon as the engine is running, the function can be activated by connecting to +U_Bat(Operating readiness or terminal 15).

Important:The implementation of SET+/SET- via the KSM interface is only possible in the ZDR modes for which the condition “Steering column lever active” is set. It should be ensured that the steering column lever is secured against undesirable interference within the driver’s cab during operation, for example via an external remote control.

OFF (Plug connection X1997/Pin 15)

+U_Bat -switch signal input for enablement/cancelling of the ZDR functions.

Function:
If the input is connected to +U_Bat (Operating readiness: X1997/PIN12) the ZDR functions are enabled. By setting “OPEN” for the external bridge between “Operating readiness” (X1997/PIN12) and “OFF” (X1997/PIN15) the ZDR and cruise control functions are cancelled.

Important:
If the external bridge between X1997/PIN12) and X1997/PIN15) is not present. the “OFF” function is permanently activated/cruise control functions are not possible.

MEMORY (Plug connection X1997/Pin 16)

+U_Bat -switch signal input for retrieval/storage of an engine speed value.

Function:
If the input is connected to +U_Bat the engine, on expiry of the checking signal (t_max<1sec.) goes to the values ZDR S, ZDR1,…ZDR7 for which the parameters can be set by means of MAN-cats II, and regulates them. Following a change, for example by “SET+” or “SET-”, the new engine speed value can be stored by connecting the input with +U_Bat (t > 2sec.).
The new engine speed value is cancelled, i.e. the engine goes to idle speed (ZDR S) or the lower rev. limit (ZDR1, …ZDR7) by means of the “OPEN” command for the external bridge between X1997/PIN12 and X1997/PIN15, by operating the “OFF control switch” on the control panel in the cabin, or if one of the cancellation conditions is fulfilled.

Function enablement:
As soon as the engine is running, the function can be activated by connecting with +U_Bat (Operating readiness or terminal 15) subject to time “t” referred to above.

Important:
The MEM function only takes effect when the control switch is enabled (change of input flank from “high” to “low”). The storage of a target engine speed value that was set using SET+/- is only possible in the corresponding ZDR mode if at the FFR the operator input of the parameter “active with storage in memory” is set and the switch held down for at least 2 seconds.

A-CAN-H (Plug connection X1997/Pin 17)

CAN-high cable for FMS/body CAN interface.

A-CAN-L (Plug connection X1997/Pin 18)

CAN-low cable for FMS/body CAN interface.

NMV (Plug connection X3311/Pin 1)

+U_Bat –signal input. When the NMV switch is not activated (contact open) the setting is at the “low” level for the KSM PIN (digital input, 4,75kΩ-pull-down, switching level: U_low<3 / U_high>16V) “NMV request”. With this PIN the NMV can also be requested. This only applies if the NMV switch is fitted.

Load:
Max 500mA

Function:
Information that the NMV was requested or can be used to request NMV. However, the NMV is only activated if the conditions which have been set as parameters in the KSM (by means of the vehicle data file) apply; these are:

•   Only engage NMV if Gearbox N: “active”/”not active”
•   Only engage NMV if handbrake has been applied: “active”/”not active”
•   Only engage NMV if vehicle is stationary: “active”/”not active”

Note:
If the conditions for connecting for Gearbox N, handbrake, clutch or speed signal have been given “active” parameters, they must be fulfilled as soon as the NA request is made, so that the valve can be energised. Once the power take-off has been activated, it remains so even if the conditions for connection are no longer fulfilled later. The connection conditions are considered to be AND-linked.

• NMV with parameter “Engine speed threshold on”: “active”/not active”

Note:
Regarding the switching condition “Engine speed threshold on”: providing that that the connection conditions (Gearbox N, handbrake, vehicle stationary) are fulfilled (if they have been given “active” parameters) and if the power take-off is requested, the valve is energised as soon as the engine speed exceeds the threshold at which the parameter has been set. The valve remains energised even if the engine speed subsequently drops below this threshold.

• NMV with the parameter “engine speed threshold ‘on/off’”: “active”/”not active”

Note:
Regarding conditions for switching on and off if “engine speed threshold on/off”:
Providing that the connection conditions (Gearbox N, handbrake, vehicle stationary) are fulfilled (if they are given “active” parameters) and if the power take-off is requested, the valve is energised as soon as the engine speed exceeds the threshold to which the parameter has been set. The power is cut off if the engine speed drops below the lower threshold .The conditions for re-energising the valve if the upper engine speed threshold is exceeded are that the request is still active and the connection conditions are still fulfilled.

• NMV request
Parameters can be set to determine whether the switch (digital KSM input) is supported. If the input is supported, then a possible instruction from the A-CAN is ignored. If the input is not supported, then a possible demand from the A-CAN is processed and the switch (digital KSM input) is ignored. Both requests can also be logically linked with “OR” and a demand via A CAN and the digital input is possible.

Function enablement:
As soon as +U_Bat is connected following a successful engine start.

Factory settings

Connection condition gearbox-N	"active"
Connection condition handbrake	"active"
Connection condition vehicle stationary	"active"
Engine speed threshold "on"	"not active"

COMPRESSED AIR SWITCH NMV (Plug connection X3311/Pin 2)

-U_Bat -switch signal output, same potential as at LED for the NMV switch of the compressed air switch when the NMV is switched on.
When the NMV is not operating, the switch signal output of the compressed air switch is at the “high” level (approx. +U_Bat) (only if NMV switch is fitted).

Load:
Max 500mA

Function:
Information that the NMV is switched on.
Can be used for enabling the engine speed or power take-off functions in order to prevent undesired external access to operating controls from outside the driver’s cabin.

Important:
The NMV switch is not included in the standard equipment of the vehicle and must be ordered separately.!

Converter lockup clutch (WSK) OPEN/ UPSHIFT INHIBIT (Plug connection X3311/Pin 3)

+U_Bat -switch signal for request “WSK/upshift inhibit” for HP transmission (ECOMAT).

Function:
If the input is connected to +U_Bat no upshifts will be carried out as long as the function is activated. If the function is activated when the vehicle is stationary and with Gearbox N, the appropriate starting gear will be selected, by movement of the DNR switch from “N” to a drive position, or if the DNR switch is at a drive position by deactivating the external Gearbox N request. In both cases the drive-off gear will only be engaged if the brake pedal is operated.

Function enablement:
As soon as +U_Bat (Operating readiness or terminal 15) is present.

PWM_KONFIG (Plug connection X3311/Pin 4)

PWM signal output. The signal has the following specification:
• Maximum output current: 10 mA
• Output voltage “low” is below 20% +U_Bat
• Output voltage (high) is above 80% +U_Bat
• The internal pull-up resistance is 15 kΩ; the basic status on the PIN is therefore “high”
• The output frequency can be set via a parameter.

Function:
Output of the signal depending on which parameters have been set.

Parameter which can be set:
•   Output active with signal “driver’s desired torque”           (SAE J1939/71: „drivers`demand engine torque”)
•   Output active with signal “actual engine torque”               (SAE J1939/71: „actual engine torque”)
•   Output active with signal “load current speed”                  (SAE J1939/71: „load at current speed”)
•   The output frequency can be set by parameters in a range of 100 ... 400Hz

Note:
The checking ratio of the PWM signal describes the “high time” (e.g. 10% = 10% “high” and 90% “low”).
For example.:                Torque 0%:                    checking ratio 10%
                                     Torque 50%:                 checking ratio 50%
                                     Torque 100%:               checking ratio 100%

EXTERNAL GEARBOX-N DEMAND/CLUTCH RELEASED (Plug connection X3311/Pin 5)

+U_Bat -switch signal input for demand “Interrupt drive line”.

Function:
• For automated shift gearboxes and HP transmissions:
If the input is connected to +U_Bat the gearbox is switched to Neutral. When +U_Bat is removed, a gear is engaged again. The gearbox is only switched an external N below a speed threshold for which a parameter has been set. The request for this can also be set above the speed threshold for which the parameter has been set.

• Only for HP transmissions:
When the vehicle is stationary and with Gearbox N, the corresponding drive-off gear is engaged by movement of the DNR switch from “N” to a drive position, or if the DNR switch is already at a drive position by de-activating the external Gearbox N demand. In both cases the drive-off is only selected if the brake pedal has been operated. New parameters can be set which cause the request to be carried out as a “switch function” or a “check function”.
The “check function” is only effected when the switch is released (change of input flank from “high” to “low”).

Function enablement:
Approximately 3.5 seconds after terminal 15 “on”, the function can be activated by connecting to +U_Bat
(Operating readiness or terminal 15).

Factory settings

external gearbox N/clutch released: "switch function"	Frequency
external gearbox N/clutch released: "check function"	200 Hz

HP TRANSMISSION [ECOMAT] PROGRAMME CHANGE (Plug connection X3311/Pin 6)
