operate safely at a higher output frequency. The warning
clears when the output drops below the maximum limit.
WARNING/ALARM 65, Control card over temperature
The cut-out temperature of the control card is 85 °C
(185 °F).
Troubleshooting
•
Check that the ambient operating temperature is
within the limits.
4 4
•
Check for clogged filters.
•
Check the fan operation.
•
Check the control card.
WARNING 66, Heatsink temperature low
The frequency converter is too cold to operate. This
warning is based on the temperature sensor in the IGBT
module. Increase the ambient temperature of the unit.
Also, a trickle amount of current can be supplied to the
frequency converter whenever the motor is stopped by
setting parameter B-00 DC Hold Current to 5% and
parameter H-80 Function at Stop.
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down. Check that the configuration
change is intentional and reset the unit.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
Troubleshooting
•
Check that the ambient operating temperature is
within limits.
•
Check for clogged filters.
•
Check fan operation.
•
Check the power card.
ALARM 70, Illegal drive configuration
The control card and power card are incompatible. To
check compatibility, contact the GE supplier with the
model number from the unit nameplate and the part
numbers of the cards.
ALARM 80, Drive initialised to default value
Parameter settings are restored to factory settings after a
manual reset. To clear the alarm, reset the unit.
ALARM 91, Analog input 54 wrong settings
Set switch S202 in position OFF (voltage input) when a
KTY sensor is connected to analog input terminal 54.
ALARM 92, No flow
A no-flow condition is detected in the system.
Parameter AP-23 No-Flow Function is set for alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
208
ALARM 93, Dry pump
A no-flow condition in the system with the frequency
converter operating at high speed may indicate a dry
pump. Parameter AP-26 Dry Pump Function is set for alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
ALARM 94, End of curve
The feedback is lower than the setpoint. This may indicate
leakage in the system. Parameter AP-50 End of Curve
Function is set for alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. Parameter AP-60 Broken Belt Function is set
for alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle
protection. Parameter AP-76 Interval between Starts is
enabled.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
WARNING 97, Stop delayed
Stopping the motor has been delayed because the motor
has been running for less than the minimum time specified
in parameter AP-77 Minimum Run Time.
WARNING 98, Clock fault
Time is not set, or the RTC clock has failed. Reset the clock
in parameter K-70 Date and Time.
WARNING 200, Fire mode
The frequency converter is operating in fire mode. The
warning clears when fire mode is removed. Refer to the
fire mode data in the alarm log.
WARNING 201, Fire mode was active
The frequency converter has entered fire mode. Cycle
power to the unit to remove the warning. Refer to the fire
mode data in the alarm log.
WARNING 202, Fire mode limits exceeded
While operating in fire mode, 1 or more alarm conditions
that would normally trip the unit have been ignored.
Operating in this condition voids unit warranty. Cycle
power to the unit to remove the warning. Refer to the fire
mode data in the alarm log.
