Alarms
Non-essential load (NEL)
• Up to 3 non-essential loads per controller
• Can connect each controller to the same 3 non-essential load breakers
NEL # over-current (1 alarm for each non-essential load)
NEL # under-frequency (1 alarm for each non-essential load)
NEL # overload 1 and 2 (2 alarms for each non-essential load)
NEL # reactive overload (1 alarm for each non-essential load)

8.7.2 Alarm actions
The GENSET controller has the following alarm actions:
• Warning
• Block
• PMS-controlled stop
• Trip generator breaker
• Trip generator breaker and stop engine
• Trip generator breaker and shutdown engine
• Trip AVR*
• Trip generator breaker + AVR*
• Trip generator breaker + AVR + stop engine*
• Trip generator breaker + AVR + shutdown engine*
*Note: These alarm actions are only available if the Trip AVR digital output is configured.
8.7.3 Inhibits
The controller includes the following inhibits:
Table 8.27
