Service and Maintenance
FAULT:
Motor runs but switch will not latch.
QUESTION: Did the machine
stop whilst running?
ACTION: CHECK THE
POWER SUPPLY
QUESTION: Has the machine been running
and then switched off in the last 60 mins?
ACTION: Check and test the thermal
protection device.
METHOD: Switch off the mixer allowing it to
cool for 20 mins.
NOTE: A trip out could be caused by
low voltage supply. If tripping continues
investigate power supply as follows……….
ACTION: Check and test the thermal protection device.
METHOD: Hold the ON button down for a minimum of 2
minutes, this will allow the fan on the motor to cool the
system.
NOTE: A trip out could be caused by low voltage
supply. If tripping continues investigate power supply as
follows……….
110 Volt
230 Volt
Mains supply
GENERATOR
QUESTION: What size generator is being used?
NOTE: Minimum output 2.2KVA continuous rated. Low
supply voltage can cause the thermal trip to operate and
/ or provided insuffi cient power to operate switch coil.
TRANSFORMER
QUESTION: What size transformer is being used?
NOTE: Minimum transformer 2.5KW continuous rated.
Low supply voltage can cause the thermal trip to operate
and / or provided insuffi cient power to operate switch coil.
QUESTION: Is extension cable being used?
QUESTION: How long is the extension cable?
NOTE: Maximum cable length 30 meters. Longer cables cause
voltage drop. Low supply voltage can cause the thermal trip to
operate and / or provided insuffi cient power to operate switch
coil.
QUESTION: Can the supply
voltage be measured safely?
ACTION:
110V Plug transformer direct into the
mains then the machine direct into the
transformer (No extension cables)
230V Plug the machine direct into the
mains (No extension cables)
INFORMATION:
230V: Minimum voltage should 218.5 Volts (-5%)
110V: Minimum voltages should be 104.5 Volts (-5%)
Low supply voltage can cause the thermal trip to operate
and / or provided insuffi cient power to operate switch coil.
QUESTION: Does the
machine operate normally?
QUESTION: Is the correct
supply being used?
Switch will still not hold in
A replacement switch is required
The mixer will only operate as designed when used with the correct supply voltage.
ALWAYS ENSURE THE CORRECT SUPPLY VOLTAGE IS USE
