Pneumatic system equipment control module, function - GF80.30-P-4004-01A

DAS 2a 

Function 

Models 129/149/202 

To unlock, the pneumatic system equipment (PSE) control module is actuated by the IR DAS control module.

Models 170/210 

To unlock, the multi-function control module is actuated by the IR DAS control module. The multi-function control module then sends the signal to the PSE control module via the CAN bus.

The pump motor starts running and supplies pressure. The CL actuators are pressurized. When a pressure of 450 mbar is reached in the system the pump is switched off by the pressure switch. The pressure in the system is then released by the PSE control module and the unlocking operation is completed.

The locking procedure is accomplished analog to the unlocking operation. However the next time the remote control button is pressed the PSE control module is also actuated by connecting it through to ground by the second control lead on the IR DAS control module. The direction of rotation for the pump motor is reversed thereby providing the vacuum required to lock.
