Display Messages
The ZENER 8000-V displays a variety of messages to indicate its status. These message displays may be divided
into two types: Fault messages and Status messages
Fault Messages
The ZENER 8000-V will protect itself against a variety of fault conditions. When one or more of these conditions
occur, the ZENER 8000-V will trip, shut down the motor and display one or more fault messages on the top line
of the console display. The messages will be displayed until the fault is cleared and a reset signal is asserted.
Fault messages include:
Fault Message Description
UA1: ALARM User defined trip alarm. Refer to G233 Alarm text for message customisation.
UA2: ALARM
User defined trip alarm. Refer to G243 Alarm text for message customisation.
UA3: ALARM
User defined trip alarm. Refer to G253 Alarm text for message customisation.
UA4: ALARM
User defined trip alarm. Refer to G263 Alarm text for message customisation.
THERMISTOR HOT The thermistor wired to the Extended features card indicates the motor is over heated
THERMISTOR SHORT
The thermistor wired to the Extended features card is short circuit
SUPPLY FAIL
There is a problem with the input power supply. One phase is partially missing and motor
operation will be impaired
BRAKE SHORT
Either an Over Current or a Ground Fault has been detected on the dynamic brake resistor
terminals
EARTH FAULT An earth leakage fault has been detected
I2t OVERLOAD
An I2t overload trip has occurred
CHARGE FAULT
A rectifier failure has been detected
DC BUS LOW The DC bus voltage has fallen below its minimum threshold
POWER FAILURE All phases on the input power supply are either low or missing
OVER CURRENT
The output current has exceeded the ZENER 8000-V's intermittent output current rating
IMBALANCE OC
One inverter module is conducting too much current.
(Parallel systems only)
RELAY OPEN
The internal bus charge relay has failed to operate correctly
OVER VOLTAGE
The DC bus voltage has exceeded its maximum value
OUTPUT SHORT
An output short circuit has been detected. This is caused by either an Over Current or
Ground fault on the motor terminals
Tj OVER TEMP
The ZENER 8000-V has determined a power device Junction is too hot
HOT INTERNAL AIR The internal air temperature has risen beyond the protection rating of the ZENER 8000-V
Ths OVER TEMP
The internal heat sink temperature has risen beyond the protection rating of the ZENER
8000-V
Tefct OVER TEMP
The earth fault current transformer temperature has risen beyond the protection rating of
the ZENER 8000-V
T1 OVER TEMP
The temperature of sensor T1 has risen beyond the protection rating of the ZENER 8000-V
