6. Electrical Fault Finding
(Continued)
6.2
Coolant Pump
If the voltage is correct at the coolant pump a new pump is required.
6.3 Traverse Motor
If the voltage is correct at the traverse motor terminals, check for an error message at the
invertor display 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).
6.4 Mounting Bar Motor
If the voltage is correct at the motor terminals, check for an error message at the invertor
display.
6.5 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).
6.6 Magnets
Check for 12V DC at terminals 2 and 3 at the 4 pole socket at the rear of the drawer. If no
volts are present, check output at transformer ( Warning : where voltage will be AC!).
