the correct motor leads have been routed
through the ground fault current
transformers in the right direction. Check
for condensation on motor terminals or
inside of motor leads. Check motor power
leads for phase to phase or phase to
ground shorts. Disconnect motor from
starter and merger motor windings to
ground and phase to phase. Call Carrier
Service.
ALM-410 ISM Fault -
Phase Reversal Trip
The ISM has detected that the input power
is phased BAC instead of ABC. Confirm
that the phase sequence wired to ISM
terminal block J3 is consistent with the
power wiring to the starter. Swap two
power leads at the starter.
ALM-411 ISM Fault -
Line Frequency Trip
LINE FREQUENCY FAULTING in
ISM_CONF screen is enabled and the
LINE FREQUENCY has deviated
approximately 7% from nominal value.
Check ISM_HIST screen. Check
FREQUENCY = 60 HZ? In ISM_CONF
screen. Check line frequency. If
operating from a generator, check
generator size and speed.
ALM-412 ISM Fault -
Starter Module Reset
AUTO RESTART OPTION in OPTIONS
screen is disabled and there was a
temporary loss of 115 V ISM control
voltage supply. Check ISM_HIST screen.
Check wiring leading to ISM terminals J1-
LL1 and J1-LL2. Check control power
circuit breaker, control power transformer
and control power circuit fuses. Monitor
chiller utility power for disruptions.
Improve ISM ground connection, apply
measures to reduce electrical noise to
ISM. Consult power company.
ALM-413 ISM Fault -
Start Contact Fault
Check 1M dry contact input
ALM-414 ISM Fault -
Transition Contact
Fault
Check 2M dry contact input
ALM-415 ISM Fault -
OIl Pump / HPS Failure
Check high pressure switch and oil pump
for legacy chiller and oil pump for NGC
chiller
ALM-416 ISM Fault -
Starter Fault
The ISM has received a start command
and the starter has declared a Fault. The
dry contacts connected to ISM J2-7 and
J2-8 are open. See starter display for
starter Fault Code. For Benshaw Inc.
RediStart starters, 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 ISM Fault -
Motor Amps Not
Sensed
The ISM has not sensed sufficient current
for an excessive delay after 1M has
closed. If LF1, verify J4 jumper on
regulator card is on pins 1 and 2 (4-20mA).
Check the MOTOR CURRENT CT RATIO
and the MOTOR RATED LOAD AMPS in
the ISM_CONF screen. Check VFD
