Start/stop control
Control of ignition for the left bank
Governing of the engine
Air/fuel ratio control
Monitoring of the detonation sensors on the left bank
Diagnostics of the electrical system
Monitoring and protection of engine operationSlave ECM (3) supports the following functions:
Control of ignition for the right bank
Monitoring of the detonation sensors on the right bankAuxiliary Sensing Module (ASM) (2) improves the genset's ability to maintain a consistent level of frequency and voltage.The modules do not have a removable personality module. The software is changed by programming a flash file into the module via the Caterpillar Electronic Technician (Cat ET).
