Alm-413
ALM-413 ISM Fault —
Start Contact Fault
Manual Unit shuts down. Check 1M dry contact input.
Alm-414
ALM-414 ISM Fault —
Transition Contact Fault
Manual Unit shuts down. Check 2M dry contact input.
Alm-415
ALM-415 ISM Fault —
High Condenser Pressure
Manual Unit shuts down. Check high pressure switch.
Alm-416
ALM-416 ISM Fault —
Starter Fault
Manual Unit shuts down.
The ISM has received a start com-
mand and the starter has declared
a Fault. The dry contacts con-
nected to ISM J2-7 and J2-8 are
open. See starter display for starter
Fault Code.
For Benshaw Inc. RediStart start-
ers, view RediStart MICRO display.
For VFD, check VFD display Fault
History. Clear VFD faults with VFD
keypad.
For Allen-Bradley wye delta starters
with RLA > 718 A, the TR3 timer
may have expired as a result of a
delayed transition.
Alm-417
ALM-417 ISM Fault —
Motor Amps Not Sensed
Manual Unit shuts down.
The ISM has not sensed sufficient
current for an excessive delay after
1M has closed.
Check ISM_HIST screen
Check the MOTOR CURRENT CT
RATIO and the MOTOR RATED
LOAD AMPS in the ISM_CONF
screen.
Check VFD OPTION configuration.
Check for wiring of current trans-
formers to the J4 ISM terminals.
Check if main circuit breaker has
tripped.
Check ISM Status under the Main-
tenance Menu.
Alm-418
ALM-418 ISM Fault —
Excessive Acceleration
Time
Manual Unit shuts down.
Any line current remains high for an
excessive time duration following
1M aux and either 2M aux or transi-
tion contact closure.
Check that inlet guide vanes are
fully closed at start up.
Check ISM_HIST screen.
Check Motor Rated Load Amps in
ISM_CONF screen.
Reduce condenser pressure if pos-
sible.
Check ISM Status under the Main-
tenance Menu.
