Data Point Name | Access | Value Type | Point Source | Description |
Amps A | Read Only | Analog | Generator Controller (or meter if not present) | Amps on leg A measured at the output of the generator. |
Amps B | Read Only | Analog | Generator Controller (or meter if not present) | Amps on leg B measured at the output of the generator. |
Amps C | Read Only | Analog | Generator Controller (or meter if not present) | Amps on leg C measured at the output of the generator. |
Battery Charge Alarm | Read Only | Digital | Generator Controller | Engine battery charger has gone into alarm. This is a warning alarm and could prevent the engine from running. |
Battery Voltage | Read Only | Analog | Generator Controller (blank if not present) | Battery voltage in volts of the engine batteries. |
Common Alarm | Read Only | Digital | Generator Controller (hard-wired if not present) | True if any alarm (warning or shutdown) is present on the engine. If true, engine may not run when called up for dispatch. |
Coolant Temp | Read Only | Analog | Generator Controller (blank if not present) | Engine coolant temperature of the engine in degrees F. |
Emergency Stop | Read Only | Digital | Generator Controller | The Emergency stop button has been hit at the Generator. This is a shutdown alarm, the Generator will not run until the button is released and alarm is cleared onsite. |
Frequency | Read Only | Analog | Generator Controller (or meter if not present) | Voltage frequency measured at the output of the generator. |
Fuel Level | Read Only | Analog | Generator Controller (blank if not present) | For diesel engines, fuel level remaining of diesel belly tank. |
High Battery Volts | Read Only | Digital | Generator Controller | High battery voltage is detected on the engine batteries. Generator will run but further onsite investigation is needed. |
High Engine Temp | Read Only | Digital | Generator Controller | Engine coolant temp has gone above the critical level. This is a shutdown alarm, generator will not run until this is addressed onsite. |
kVAR | Read Only | Analog | Generator Controller (or meter if not present) | Reactive power reading measured at the output of the generator. |
kW | Read Only | Analog | Generator Controller (or meter if not present) | Real power reading measured at the output of the generator. |
kWh | Read Only | Analog | Generator Controller (or meter if not present) | Total real power consumption measured at the output of the generator. |
Low Battery Volts | Read Only | Digital | Generator Controller | Low battery voltage is detected on the engine batteries. Generator will run but further onsite investigation is needed. |
Low Coolant Level | Read Only | Digital | Generator Controller | Engine coolant level has gone below the critical level. This is a shutdown alarm, generator will not run until this is addressed onsite. |
Low Coolant Temp | Read Only | Digital | Generator Controller | Engine coolant temp has gone below the critical level. This is a shutdown alarm, generator will not run until this is addressed onsite. |
Not in Auto | Read Only | Digital | Generator Controller (hard-wired if not present) | True when engine is taken OUT of Auto and put into either the Manual or Off position. If true, engine will not run as expected when called upon for dispatch. |
Oil Pressure | Read Only | Analog | Generator Controller (blank if not present) | Oil pressure of engine in PSI. |
Oil Pressure Low | Read Only | Digital | Generator Controller | Engine oil pressure has gone below the critical low level. This is a shutdown alarm, generator will not run until this is addressed. |
Overcrank | Read Only | Digital | Generator Controller | Engine is attempting to start but is not able. This is a shutdown alarm, generator will not run until this is addressed. |
Overspeed | Read Only | Digital | Generator Controller | Engine speed has gone above expected operating parameters. This is a shutdown alarm, generator will not run until this is addressed. |
Power Factor | Read Only | Analog | Generator Controller (or meter if not present) | Power factor measured at the output of the generator. |
Pre High Engine Temp | Read Only | Digital | Generator Controller | Engine coolant temp has gone above the warning level. This is a warning alarm, generator will run but further site investigation is necessary. |
Pre Low Oil Pressure | Read Only | Digital | Generator Controller | Low engine oil pressure is detected. Generator will run but further onsite investgation is needed. |
Running | Read Only | Digital | Generator Controller (hard-wired if not present) | True when engine is running. |
Shutdown Alarm | Read Only | Digital | Generator Controller | Any shutdown alarm is present on the generator. The engine will not run until addressed or cleared. |
Supplying Load | Read Only | Digital | Generator Controller (or meter if not present) | Generator is providing standby power to the site. |
Start | Read/Write | Digital | Generator Controller (hard-wired if not present) | Remote start of generator. |
Volts AB | Read Only | Analog | Generator Controller (or meter if not present) | A to B line-to-line voltage reading at the output of the generator. |
Volts BC | Read Only | Analog | Generator Controller (or meter if not present) | B to C line-to-line voltage reading at the output of the generator. |
Volts CA | Read Only | Analog | Generator Controller (or meter if not present) | C to A line-to-line voltage reading at the output of the generator. |
Warning Alarm | Read Only | Digital | Generator Controller | Any warning alarm is present on the generator. The generator will run but further onsite investigation needs to be done. |
