Pin 16 Contactor 2 o/p (Magnet Brake - Fan control)

This pin can have different configurations (see “Menu 3 “Controller Setup””).

In traction software only it can be connected to the negative side of the Electro Mechanical Brake Contactor coil.

The maximum rating for this connection is 3A and it is fully protected for use with inductive loads.

In both traction and pump software it can be used to drive a cooling fan when motor and/or controller temperature

sensors signal that the temperature is above a specified threshold.

• If and electromagnetic brake is used connected to the Pin 16 the setting “M3-4T Hill hold

”Off/HH/S”” must be set to 0. Refer to parameter “M1-9T Neutral brake-End delay “NBrkEnd””

for further details.

Pin 17 Contactor 3 o/p (Powersteer - Fan control)

This pin can have different configurations (see “Menu 3 “Controller Setup””).

In traction software only it can be connected to the negative side of the Power Steer Contactor coil. The maximum

rating for this connection is 3A and it is fully protected for use with inductive loads.

In both traction and pump software it can be used to drive a cooling fan when motor and/or controller temperature

sensors signal that the temperature is above a specified threshold.

Pin 18 Digital o/p -- Remote LED or Brake lights or Drive OK

The function of this output is set in “Menu 3 “Controller Setup”” for both traction and pump applications.

Depending on the application considered, it can be used or as a remote LED, or as a Dirve OK signal or, for traction

only, as a brake light.

Pin 19 Supply 12V -- 70mA max.

A 12V supply is available for electronic accelerator or potentiometers. The maximum supply current is 70mA.

Pin 20 CAN +12V -- 70mA max.

A 12V supply is available for external CAN isolator modules or other loads. The maximum supply current is 70mA.

Pin 21 CAN H1

CAN High communications can line to the Calibrator, Display or other Controller(s) CAN Devices.

• The can communication lines are referred to battery ground.

Pin 22 CAN L1

CAN Low communications can line to the Calibrator, Display or other Controller(s)/CAN Devices.

• The can communication lines are referred to the battery 0V (ground).

Pin 23 CAN 0V

Can communication lines 0V (ground) reference.

• The can communication lines are referred to the battery 0V (ground).

Pin 24 CAN 120R Link

This pin is connected to a 120 Ohm resistor. If the controller is the CAN network wiring ending node, this pin could

be connected to the pin 25 or pin 21. See [2] for further details.
