Fault Relay Common
11 Fault Relay N.C.
12 Fault Relay N.O.
The fault relay is energized in a NO
Fault condition. In a fault condition or
a case of power loss the relay will de-
energize and the contacts will go to
there normal condition indicating a
fault.
13 Bypass Relay Common
14 Bypass Relay N.O.
This relay is used to control a by-pass
contactor either directly or indirectly if
the coil current of the by-pass contactor
is to large (>5amps). This relay will
energize once the Opal Pro has phased
full on and the motor current has
dropped below 110% of the nameplate
current.
15 Shorted SCR Relay Common
16 Shorted SCR Relay N.C.
17 Shorted SCR Relay N.O.
This relay is energized when a shorted
SCR is detected and should be used to
trip a shunt trip breaker.

19 Run Relay N.O.
This relay is energized when the unit is
running
20 Reverse Relay Common
21 Reverse Relay N.O.
This relay is energized when the unit is
running is the reverse mode
