programmable output is not required as the engine starting logic is internally
initiated.
2) When both “Utility Ready to Load” and “Generator Ready to Load”
programmable outputs are programmed and utilized in a AMF control
configuration, the ATS Output is not utilized (i.e. engine start signal is internally
generated).
5.2.11.OIL BYPASS TIMER COMPLETE
The designated programmable output relay will energize upon the expiry of the
controller's oil bypass delay timer function, following a normal start sequence.
5.2.12.COMMON ALARM
The designated programmable output relay will energize when any alarm fault
circuit has been activated.
5.2.13.COMMON FAIL
The designated programmable output relay will energize when any alarm or
shutdown fault circuit has been activated.
5.2.14.COMMON SHUTDOWN
The designated programmable output relay will energize when any shutdown
fault circuit has been activated.
5.2.15.EPS SUPPLYING LOAD
The designated programmable output relay will energize when the engine is
running and the generator is supplying current to the load more than or equal to
10% of nominal CT ratio.

EXPANSION OUTPUT MODULE OPTION
Optional expansion output modules are available for the MEC 2 engine generator controller.
Each module can provide 16 individual fault output contacts for remote alarming or control
purposes. The expansion modules are interconnected to the MEC 2 controller via RS422
communication link utilizing 8 conductor shielded cable with plug-in RJ45 connectors. Refer to
FIGURE #13 for the expansion output module connection diagram.
