15.2 Machine fault and operating problems
Problem Probable Cause Solution
Green pilot lamp not lit
when ON button pressed
No incoming power Check connections at machine and power source.
Lamp fuse or bulb is out Replace fuse/bulb.
Motor will not turn
Emergency stop engaged Rotate Emergency Stop button to disengage.
Electrical power supply
Check: the phases; the cables; the plug; the socket.
Also check that the motor connections are in place.
Trigger switch not activating
Check that socket/plug connection from handle to
motor is inserted correctly; check micro-switch in
trigger.
Transformer
Check that the voltages are present both on the input
and output. Otherwise replace.
Magnetic contactor
Check that the phases in it are present both on the
input and output, that it is not jammed, that it closes
when powered and that it is not causing short circuits.
Change if any of these problems are found.
Thermal relay
Make sure it is closed, i.e. check that the phases are
present in input and output, that it is not causing short
circuits and responds when the reset coil is closed. If it
has tripped to protect the motor, check the amperage
setting, re-set, and check the motor. Change if
necessary.
Motor
Check that it has not burned out, that it turns freely
and that there is no moisture in the connection
terminal board box. The winding can be rewound or
replaced by experienced motor repair personnel.
