OPERATION

Sequence of Operation
The relay modules have operating sequences as shown in Fig.
13 through 15.

INITIATE

The relay module enters the INITIATE sequence if the relay
module verifies voltage fluctuations of +10%/-15% or fre-
quency fluctuations of ±10% during any part of the operating
sequence. The INITIATE sequence lasts for ten seconds un-
less the voltage or frequency tolerances are not met. When
the tolerances are not met, a hold condition is initiated and
displayed on the optional KDM for at least five seconds. When
the tolerances are met, the INITIATE sequence restarts. If the
