Digital Input
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
.
