Cat Genset Monitoring System (GMS)
The Genset Monitoring System (GMS) provides protection, monitoring, and control for a single 3600 diesel generator set utilizing a digital based control panel housed in an IP55 enclosure. All critical shutdowns are a relay-based protection. Contactors are wired directly to the junction panel when an accessory module is ordered and is factory packaged. Use of the GMS eliminates the need for a separate gauge panel and annunciator panel. Accepts remote signals for starting/interlock, stopping, and emergency stop. All monitored parameters and status signals are available over MODBUS RS485 network. A default Ethernet connection is available for connection.
- Simple user friendly interface and navigation
- Provides protection, monitoring, and control of the generator set
- Redundant shutdown protection
- 5.7 inch (145 mm) color monitor to display all engine parameters and alarm annunciation
- Annunciation of all engine shutdowns, alarms, and status points
- Start/prelube control switch, fuel control switch and emergency stop button
- Selection of local/remote control of engine
- Selection of idle/rated control of engine
- Equipped for remote communication from the panel
- Relay outputs available: energize to run, energize to stop, air shutoff, prelube, air start and local remote
- Optional output available for alarms and faults
