Motor Circuit Switch (Motor Maintenance Switch)
All motor controllers and motors are deenergized with the motor circuit
switch.
This is important when, in the event of maintenance or repair, the melter
and heaters must remain switched on but the motors absolutely may not
turn.
Padlocks can be used to protect the motor circuit switch from being turned
on by unauthorized personnel.
WARNING: It takes about three minutes for all of the motor controllers to
be deenergized and actually be free of voltage. The LEDs on the motor
controller are then off.
When the motor circuit switch has been turned off, the following text
appears in the status line on the control panel: Motor repair switch open.
NOTE: When maintenance or repair work has been completed, the motor
circuit switch must be turned on again. It can then take up to 10 seconds
before the motor controllers have initialized and indicated so to the control
unit. The display in the status line does not change until this time has
elapsed.
