Switch Check Flow-Chart
FAULT:
Motor runs but switch will not latch.
QUESTION: Did the machine
stop whilst running?
YES
ACTION: Check and test the thermal
protection device.
METHOD:
cool for 20 mins.
NOTE: A trip out could be caused by
low voltage supply. If tripping continues
investigate power supply as follows..........
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
NO
NO
ACTION:
110V
mains then the machine direct into the
transformer (No extension cables)
230V
mains (No extension cables)
QUESTION: Does the
machine operate normally?

QUESTION: Has the machine been running
YES
ACTION: Check and test the thermal protection device.

supply voltage can cause the thermal trip to operate and
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
coil.
QUESTION: Can the supply
voltage be measured safely?
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
NO
Switch will still not hold in
A replacement switch is required
