Installation
Circuit Board Connections
If an output contact is operating as an “extra alarm” (driven by the same signal
that operates the dedicated ALARM output contact), it will be in the opposite
state of the dedicated ALARM output contact in a standard relay shipment. In
a standard relay shipment, the dedicated ALARM output contact comes as a b
type output contact and all the other output contacts (including the “extra
alarm”) come as a type output contacts.
The output contact type for any output contact can be changed (see Output
Contact Jumpers on page 2.23). Thus, the dedicated ALARM output contact and
the “extra alarm” output contact can be configured as the same output contact
type if desired (e.g., both can be configured as b type output contacts).

Position Output Contact OUT107 Operation
Output contact OUT107 is operated by Relay
Word bit OUT107. Jumper JMP23 comes
in this position in a standard relay ship-
ment (see Figure 7.27).
“Extra Alarm” output contact is operated
by alarm logic/circuitry. Relay Word bit
OUT107 does not have any effect on output
contact OUT107 when jumper JMP23 is in
this position (see Figure 7.27).

The OPEN, CLOSE, and PULSE commands are used primarily to assert output contacts for circuit
breaker control or testing purposes (see Section 10: Serial Port Communications and
Commands).
OFF
(removed/not in place)
Disable serial port commands OPEN,
CLOSE, and PULSE
