9. Troubleshooting
In order to prevent damage or serious injury while rectifying machine faults, the following points must be
observed:
•
Only attempt to rectify a fault if you have qualified personnel. This means each job must be carried out by trained
specialist personnel, for example electrical work must be performed by a trained electrician.
•
Always secure the machine against an accidental restart by disconnecting it from the electric system. Take appropriate
safety precautions.
•
Always have a second person make sure the machine is switched off in an emergency.
•
Secure moving parts to prevent injury.
•
Independent work on the machine is at one's own risk and releases the manufacturer from any warranty obligation.
The machine will not start
Cause
Electricity supply interrupted – short circuit or earth
connection in the cable or motor windings
Fuses, the motor protection switch and/or monitoring
devices are triggered
The moisture sensors (option) has interrupted the power circuit (operator-
related)
Machine runs but does not pump
Cause
No pumped fluid
Intake blocked
Impeller/propeller blocked or obstructed
Defective hose or piping
Intermittent operation
The motor starts, but the motor protection switch triggers shortly after start-up
Cause
The thermal trigger on the motor protection switch is incorrectly set
Increased power consumption due to major voltage drop
Excessive voltage differences on the three phases
Incorrect direction of rotation
Impeller/propeller impeded by adhesive material, blockages and/or solid
matter, increased current consumption
The pumped fluid is too dense
Remedy
Have the motor and wires checked by a specialist and replaced if ne-
cessary
Have a specialist inspect the connection and correct them as necessary
Have the motor protection switch adjusted according to the technical
specifications, and reset monitoring equipment.
Check that the impeller/propeller runs smoothly. Clean it or free it as
necessary
See fault: Mechanical shaft seal leaks, sealing chamber monitor reports
fault and switches the machine off
Remedy
Open the container intake or sliders
Clean the intake, slider, suction port or intake strainer
Switch off the machine, secure it against being switched on again and free the
impeller/ propeller
Replace defective parts
Check the control panel
Remedy
Have a specialist compare the setting of the trigger with the technical
specifications and adjust it if necessary
Have an electrician check the voltage on each phase and rewire if ne-
cessary
Have a specialist inspect the connection and the switching system and
correct it as necessary
Swap the 2 phases from the mains supply
Switch off the machine, secure it against being switched on again and free the
impeller/ propeller or clean the suction port
Contact the manufacturer
