GENSET MONITORING SYSTEM

The GMS (Genset Monitoring System) provides protection, monitoring, and control for a single 3600 diesel generator set utilizing a PLC (programmable logic controller) based system housed in a NEMA 4 (IP66) enclosure. All critical shutdowns have both relay based and PLC based protection. Sensors are wired directly to the GMS control panel. Use of the GMS eliminates the need for a separate gauge panel and annunciator panel. Requires 24 VDC power and control air pressure.

 

GMS PROTECTION SYSTEM ADDITIONS

Includes the following:

1                ea. - Generator Cooling System Flow Switch 1 ea. - Generator Lube Oil Pressure Contactor

2                ea. - Generator water temperature RTD Additional monitoring parameters:

Generator bearing vibration alarm, Generator water flow, Generator low oil pressure alarm and shutoff, Generator leak detector, TEWAC water temperature alarm (2).

 

MOUNTING SYSTEM

Includes Offshore rigid 3-point base.

 

Isolator weld plates - Includes (8) isolator weld plates for connection of isolators to customer foundation.  The weld plates ease in the genset package installation. The weld plates have threaded holes which match the isolator hole pattern.  The weld plates are to be welded to the customer foundation at the time of package installation. Weld plates are shipped loose.
