Shutdowns and Alarms
Shutdowns and Alarms menu is used to configure the various safety functions of
the EGCP-2.
Each alarm setpoint can be set for:
• Disabled
• Warning—LED on control flashes.
• Visual Alarm—LED flashes, and Visual Alarm relay energizes.
• Audible Alarm—LED flashes, Visual and Audible Alarm relays energize.
• Soft Shutdown—LED turns on, Visual and Audible Alarm relays energize,
unit soft unloads, Fuel Solenoid relay de-energizes and cycles through cool
down timer when applicable. Unit removes itself from auto sequencing
order.
• Hard Shutdown--Same as above, but immediately opens generator breaker
and de-energizes the fuel solenoid.
Voltage Range Alarm
• Alarm/Shutdown point for an excess of voltage bias signal from the EGCP-2
to AVR.
• Preset to trigger at ±100% voltage bias output.
• Indicates that the AVR is not responding to the voltage bias output as
expected.
Rated Generator Voltage
Generator High Voltage Limit (Voltage Bias Cutout)
Generator Low Voltage Limit (Voltage Bias Cutout)
Operating Range
Figure 3-19. Generator High/Low Voltage Alarms
Generator Volt High Limit (numeric)
• Sets maximum allowable generator voltage level.
• If voltage is above High Limit, generator is not considered stable, and is
unfit for breaker closure.
Generator Volt Low Limit (numeric)
• Sets minimum allowable generator voltage level.
• If voltage is below Low Limit, generator is not considered stable, and is unfit
for breaker closure
• Voltage Bias will not decrease while generator voltage is below the low limit.
