Customer Communication Module (CCM) | |
The Customer Communication Module (CCM) provides a communication link between the GSC+P and the host computer of the customer. The CCM converts data from the standard RS-232C format to the CAT Data Link format. The CCM can also convert data from the CAT Data Link format to the standard RS-232C format. RS-232C cable is available at most stores that sell electronics. Caterpillar's 146-8488 RS-232C Cable is a suitable cable. The CCM allows an operator to remotely control the same information that is available on the GSC+P display at the host computer.
The CCM can remotely control the following functions when the GSC+P is in the normal mode with the Engine Control Switch (ECS) in the AUTO position.
- Start the engine.
- Stop the engine if the remote start/stop contact is not closed.
- Activate or deactivate the Electronic Governor Relay (EGR), provided that the low oil pressure shutdown setpoint has been exceeded.
- Activate the GFR or deactivate the GFR, provided that the GSC+P has not detected a fault. In this case, the GSC+P will already have activated the GFR.
- Remotely abort the cooldown.
- Remotely control the spare output.
- Remotely control the programmable spare relay.
Note: The CCM can only control the spare output in an active low type of configuration. Refer to System Operation, "Spare Input/Output Programming OP6" for more information.
The addition of a specified modem allows two-way communication when the generator set and the host computer are separated by great distances.
For more information regarding the CCM, refer to the Operations And Maintenance Manual, SEBU6874, "Customer Communication Module (CCM) for Diesel Engines". This manual contains information for the EMCP II, EMCP II+ and EMCP II+P.
