5. Electrical Fault Finding
(Continued)
5.2
Coolant Pump
If the voltage is correct at the coolant pump a new pump is required.
5.3
Traverse Motor
If the voltage is correct at the traverse motor terminals, try fitting a new capacitor before
assuming that the motor itself is at fault.
If the traverse jumps at the change in direction, check microswitch and contactor operation
but most likely is a capacitor failure (often resulting from a low voltage supply).
5.4
Grinding Motor
If the voltage is correct at motor terminals check the current/amps at terminals T2 & T3 (on
thermal overload contactor, then at “MAIN” plug on Control PCB). If the current exceeds the
full load current indicated on the motor plate, a new motor is needed. If below full load current
the overload could be set too low (see Service Bulletin #4).
5.5
Magnets
Check for 12V DC at terminals 2 and 3 at the 4 pole socket at the rear of the drawer (closest
to the largest 16 pole connector. If no volts are present, check output at “MAGNET” plug on
main Control PCB - then at transformer (
Warning
: where voltage will be AC).
