REGEN SWITCH
The Regen Switch is used by the operator to initiate a parked regeneration. If “DPF J1939 Regen
SW Enable” is active, the CPC will no longer process the hardwired DPF Regen Switch requests.
The CPC must receive regular periodic switch status messages over J1939.
The Regen Switch is a momentary normally open switch. Refer to section 5.19 for additional
information.
Installation
The Regen Switch is wired to the CPC #4 connector pin 4/17. A switch is required or wiring
must be available to connect an external switch.
