VLT®AutomationDrive Instruction
Manual
ALARM 93, Dry pump
A no-flow condition in the system with the Adjustable
frequency drive operating at high speed may indicate a
dry pump. 22-26 Dry Pump Function is set for alarm.
Troubleshoot the system and reset the Adjustable
frequency drive after the fault has been cleared.
ALARM 94, End of curve
Feedback is lower than the setpoint. This may indicate
leakage in the system. 22-50 End of Curve Function is set for
alarm. Troubleshoot the system and reset the Adjustable
frequency drive after the fault has been cleared.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. 22-60 Broken Belt Function is set for alarm.
Troubleshoot the system and reset the Adjustable
frequency drive after the fault has been cleared.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle
protection. 22-76 Interval between Starts is enabled.
Troubleshoot the system and reset the Adjustable
frequency drive after the fault has been cleared.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection. 22-76 Interval between Starts is enabled.
Troubleshoot the system and reset the Adjustable
frequency drive after the fault has been cleared.
WARNING 98, Clock fault
Time is not set or the RTC clock has failed. Reset the clock
in 0-70 Date and Time.
WARNING 163, ATEX ETR cur.lim.warning
The warning limit of ATEX ETR rated current curve has
been reached. The warning is activated at 83% and deactivated at 65% of the permitted thermal overload.
ALARM 164, ATEX ETR cur.lim.alarm
The ATEX ETR permitted thermal overload has been
exceeded.
WARNING 165, ATEX ETR freq.lim.warning
The Adjustable frequency drive is running more than 50
seconds below the permitted minimum frequency
(1-98 ATEX ETR interpol. points freq. [0]).
ALARM 166, ATEX ETR freq.lim.alarm
The Adjustable frequency drive has operated more than 60
second (in a period of 600 seconds) below the permitted
minimum frequency (1-98 ATEX ETR interpol. points freq. [0]).
