Alm-403
ALM-403 ISM Fault — Low
Line Voltage
Manual Unit shuts down.
Low LINE VOLTAGE for an exces-
sive amount of time. Check LINE
VOLTAGE in ISM_HIST screen.
Check MOTOR RATED LINE
VOLTAGE and UNDERVOLTAGE
THRESHOLD in ISM_CONF
screen.
Check phase to phase and phase to
ground distribution bus voltage.
Check connections to ISM terminal
block J3.
Consult power company.
Medium voltage applications only:
Check voltage potential transform-
ers and VOLT TRANSFORMER
RATIO in ISM_CONF screen.
Check wiring to ISM J3-VL1, J3-
VL2 and J3-VL3.
Check ISM Status under the Main-
tenance Menu.
Alm-404
ALM-404 ISM Fault — Line
Current Imbalance
Manual Unit shuts down.
Current imbalance > CURRENT %
IMBALANCE for greater than the
CURRENT IMBALANCE TIME.
Check settings in ISM_CONF
screen.
Check ISM_HIST screen.
Check current transformer wiring
leading to ISM terminal block J4.
Verify phase to phase and phase to
ground line voltage.
Check wiring and hardware
between building power supply and
motor.
Current imbalance may improve if
power or motor leads are rotated in
the same phase sequence.
Check ISM Status under the Main-
tenance Menu.
Alm-405
ALM-405 ISM Fault — Line
Voltage Imbalance
Manual Unit shuts down.
Voltage Imbalance > VOLTAGE %
IMBALANCE for greater than the
VOLTAGE IMBALANCE TIME.
Check settings in ISM_CONF
screen.
Check ISM_HIST screen.
Check line voltage wiring leading to
ISM terminal block J3.
Verify phase to phase and phase to
ground line voltage.
Check wiring and hardware
between building power supply and
motor.
Check ISM Status under the Main-
tenance Menu.
