Fault Codes - Watson Marlow Pumps 501 Trio Manual

Fault Codes

In the event of a failure, the inverter switches off and a fault code can be viewed on the OPm2 display. The last fault that occurred is
stored in parameter P930. e.g. '0003' indicates that the last error was F003.
Fault Code Cause
F001 Over voltage
F002 Over current
F003 Overload
F005 Inverter over temperature
(internal PTC)
F008 USS protocol timeout
F010 Initialisation fault/
Parameter loss*
F011 Internal interface fault*
F012 External trip (PTC)
F013 Programme fault*
F018 Auto-restart after fault
F030 PROFIBUS link failure
F031 Option module to link failure
F033 PROFIBUS configuration error
F036 PROFIBUS module watchdog
trip
F074 Motor over temperature
by I 2 t calculation
F106 Parameter fault P006
F112 Parameter fault P012/P013
F151-F153 Digital input parameter fault
F188 Automatic calibration failure
F201 P006 = 1 while P201 = 2
F212 Parameter fault P211/P212
* Ensure that the wiring guidelines to minimise the effects of EMI have been complied with.
When the fault has been corrected the inverter can be reset. To do this press button P twice (once to display P000 and the second
time to reset the fault), or erase the fault via a binary input (see parameters P051 - P053) or via the serial interface.
Corrective Action
Check whether supply voltage is within the limits indicated on the rating plate.
Increase the ramp down time (P003).
Check whether the required braking power is within the specified limits.
Check whether the motor power corresponds to the inverter power.
Check the motor for short-circuits and earth faults.
Check whether the motor parameters (P081 - P085) correspond with the motor
being used.
Check the stator resistance (P089).
Increase the ramp-up time (P002).
Reduce the boost set in P078 and P079.
Check whether the motor is obstructed or overloaded.
Check whether the motor is overloaded.
Check that the ambient temperature is not too high.
Check that the air inlet and outlet are not obstructed.
Check the serial interface.
Check the settings of the bus master and P091 - P093.
Check whether the timeout interval is too short (P093).
Check the entire parameter set. Set P009 to '0000' before power down.
Switch off power and switch on again.
Check if motor is overloaded.
Switch off power and switch on again.
Automatic re-start after fault (P018) is pending.
WARNING: The inverter may start at any time.
Check the integrity of the link.
Check the integrity of the link.
Check the PROFIBUS configuration.
Replace PROFIBUS module.
Check that the motor current does not exceed the value set in P083.
Parameterise fixed frequency(ies) and/or motor potentiometer on the digital
inputs.
Set parameter P012 < P013.
Check the settings of digital inputs P051 to P053.
Motor not connected to inverter - connect motor.
If the fault persists, set P088 = 0 and then enter the stator resistance of the
motor into P089 manually.
Change parameter P006 and/or P201.
Set parameter P211 < P212.
