FIGURE B.1 - CONTROL PANEL KEYS

1.Input POWER ON/OFF Switch

This toggle switch turns the machine on or off.

Putting the switch in the ON “ ” position ener-

gizes the machine’s input contactor applying input power to the machine. Switching the switch to the

OFF “ ” position de-energizes the input con- tactor.

2.POWER Light

When the POWER switch is in the ON position the machine’s white POWER light will illuminate. If the input contactor de-energizes the machine in an abnormal situation the pilot light will still illuminate. In this situation it may be necessary to reset the machine by switching the POWER switch to the OFF and then to the ON position. (See Overload, Overcurrent, and Fault Protection Section)
