“Extra Alarm”
Output Contact

Jumper
OUT107 JMP23
The position of the jumper controls the operation of the output contact next to the dedicated
ALARM output contact. With the jumper in one position, the output contact operates regularly.
With the jumper in the other position, the output contact is driven by the same signal that
operates the dedicated ALARM output contact (see
Table SECTION 2: .3).
Table SECTION 2: .3: Required Position of Jumper JMP23 for Desired Output
Contact OUT107 Operation
Position Output Contact OUT107 Operation
Regular output contact OUT107 (operated by Relay Word bit
OUT107). Jumper JMP23 comes in this position in a standard
SEL-
351P shipment (see Figure 7.26)
“Extra Alarm” output contact (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 7.26)
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 SEL-351P 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 preceding subsection Output
Contact Jumpers). 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).
