EXTERNAL INHIBIT

If the controller contains an autotransformer for reduced-

voltage starting, DC voltage will not be applied until after

transition to full voltage. Synchronization is blocked by

withholding 115 VAC from terminals 115 and IN-. When

voltage is applied to terminals 115 and IN-, the Mark V will

go into the synchronizing mode.

Effective 11/97

SYSTEM PROTECTION

This controller includes circuits that provide a means of

shutting down in the event of a stalled motor, excessive

start time (time-out period exceeded), or pole slippage

after synchronization. Where the protection system

consists of contacts in a control circuit, use the normally-

closed (NC) contacts of RLY3 to open the
