No Flow; Dry Pump; Clock Fault; Stop Delayed - Danfoss VLT AutomationDrive Programming Manual

Troubleshooting
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Unit initialized to default value
Parameter settings are initialized to default settings after a
manual reset. Reset the unit to clear the alarm.
ALARM 81, CSIV corrupt
CSIV file has syntax errors.
5 5
ALARM 82, CSIV par. err.
CSIV failed to init a parameter.
ALARM 83, Illegal option combination
The mounted options are not supported to work together.
ALARM 84, No safety option
The safety option was removed without applying a general
reset. Reconnect the safety option.
ALARM 88, Option detection
A change in the option layout has been detected. This
alarm occurs when 14-89 Option Detection is set to [0]
Frozen configuration and the option layout for some reason
has changed. An option layout change has to be enabled
in 14-89 Option Detection before the change is accepted. If
the change of configuration is not accepted, it is only
possible to reset Alarm 88 (Trip-lock) when the option
configuration has been re-established/corrected.
WARNING 89, Mechanical brake sliding
The hoist brake monitor has detected a motor speed >
10rpm.
ALARM 90, Feedback mon.
Check the connection to encoder/ resolver option and
eventually replace the MCB 102 or MCB 103.
ALARM 91, Analogue input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analog input terminal
54.
ALARM 92, No flow
A no-flow condition has been detected in the system.
22-23 No-Flow Function is set for alarm. Troubleshoot the
system and reset the Adjustable frequency drive after the
fault has been cleared.
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 de-
activated 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
sec. 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
sec. (in a period of 600 sec.) below the permitted
minimum frequency (1-98 ATEX ETR interpol. points freq. [0]).
ALARM 243, Brake IGBT
This alarm is only for F Frame drives. It is equivalent to
Alarm 27. The report value in the alarm log indicates
which power module generated the alarm:
ALARM 244, Heatsink temperature
This alarm is only for F Frame adjustable frequency drives.
It is equivalent to Alarm 29. The report value in the alarm
log indicates which power module generated the alarm.
ALARM 245, Heatsink sensor
This alarm is only for F Frame adjustable frequency drives.
It is equivalent to Alarm 39. The report value in the alarm
log indicates which power module generated the alarm.
