These shutdown alarms are set depending on the digital input
settings. The related program parameters are P_700 to P_776.
Gen Under-Frequency Phase U
Set if the genset frequency goes under the Low Frequency
Shutdown (P_516) limit for Frequency Timer (P_520) period.
Gen Over Frequency Phase U
Set if the genset frequency goes over the High Frequency
Shutdown (P_518) limit for Frequency Timer (P_520) period.
High Battery Voltage Battery
Set if the battery voltage goes over the High Battery Voltage
Shutdown (P_610) limit.
Low Fuel Level Analog In.
Set if the fuel level measured from analog input goes under the Low
Fuel Level Shutdown (P_608) limit.
High Oil Temperature Analog In. Set if the oil temperature measured from analog input goes over the
High Oil Temperature Shutdown (P_606) limit.
High Coolant
Temperature
Analog In. Set if the coolant temperature measured from analog input goes
over the High Coolant Temperature Shutdown (P_604) limit.
Low Oil Pressure
Measured
Analog In. Set if the oil pressure measured from analog input goes under the
Low Oil Pressure Shutdown (P_602) limit.
Fail To Stop Internal
Set if the engine is not stopped before the expiration of the Stop
Timer (P_505).
Fail To Start Internal
Set if the engine has not started after Start Attempts (P_504)
number of attempts.
Genset Low Voltage U-V-W
Set if any of the genset phase voltages goes under the Generator
Low Limit (P_514) voltage.
Genset High Voltage U-V-W
Set if any of the genset phase voltages goes over the Generator
High Limit (P_515) voltage.
Slave Unavailable (dual
genset mode)
Serial
Comm.
Set if a shutdown or load dump alarm has occurred in the slave
genset and Single Genset Load Enable parameter (P_A32) is set
to 0.
Gen Phase Sequence
Fail
U-V-W Set if the generator phase sequence is not correct. This alarm may
be cancelled also by programming the Ignore Phase Order
parameter (P_A06) to 1.
Low Engine Speed Magnetic
Pickup
Set if the engine rpm goes under the Low rpm Shutdown (P_613)
limit. If the Crank Teeth Count (P_619) is set to ‘0’, this alarm will
be disabled.
High Engine Speed Magnetic
Pickup
Set if the engine rpm goes over the High rpm Shutdown (P_615)
limit. If the Crank Teeth Count (P_619) is set to ‘0’, this alarm will
be disabled.
Communication Lost
(dual genset mode)
Serial
Comm.
Set if the serial communication between Master and Slave gensets
is interrupted and Single Genset Load Enable parameter (P_A32)
is set to 0.
