Customer Communication Module (CCM) The customer communication module (CCM) provides a communication link between the GSC and a host computer of the customer. The CCM converts data from standard RS-232C format to CAT data link format and vice versa. The CCM allows an operator at the host computer to remotely control and monitor the generator set. The CCM can monitor the same information that is available on the GSC display. The CCM can remotely control the following functions when the GSC is in the normal mode with the ECS in the AUTO position.
Start the engine.
Stop the engine, provided the remote initiate contact is not closed.
Activate or deactivate the EGR, provided the low oil pressure shutdown setpoint has been exceeded.
Activate or deactivate the GFR, provided the GSC has not detected a fault. (In this case, the GSC will already have activated the GFR.)
Remotely abort the cooldown time.
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. For more information, see Systems Operation, "Spare Input/Output Programming OP6". The addition of a specified modem allows two-way communication when the generator set and host computer are separated by great distances. See Operation & Maintenance Manual, SEBU6874, "Customer Communication Module For EMCP II"for more information regarding the CCM.
