Output Contact OUT4 Control Jumper Location.
If jumper JMP13 is in position ALARM and both output contacts OUT4 and
ALARM are the same output contact type (“a” or “b”), these outputswill be in
the same state (closed or open). If jumper JMP13 is in position ALARM and
output contacts OUT4 and ALARM are different output contact types (one is
an “a” and one is a “b”), these outputs will be in opposite states (one is closed
and one is open).
Clock Battery
A lithium battery powers the relay clock (date and time) if the external dc
source is lost or removed. The battery is a 3 V lithium coin cell. At room
temperature (25
C) the battery will operate nominally for 10 years at rated
load.
If the dc source is lost or disconnected, the battery discharges to power the
clock. When the relay is powered from an external source, the battery only
experiences a low self-discharge rate. Thus, battery life can extend well
beyond the nominal 10 years because the battery rarely has to discharge after
the relay is installed. The battery cannot be recharged.
If the battery voltage is out of tolerance, an automatic status message is sent to
the serial port and the front-panel display.
To change the battery, take the following steps:
Step 1. De-energize the relay.
Step 2. Remove the six front-panel screws and remove the relay front
panel.
Step 3. Disconnect the analog signal ribbon cable and power supply
cable from the underside of the relay main board.
Step 4. Grasp the black knob on the front of the draw-out assembly and
pull the assembly from the relay chassis.
Step 5. Locate the battery on the right-hand side of the relay main
board.

Required Position of
Jumper JMP13 for Desired Output Contact OUT4 Operation
Position
Output Contact OUT4 Operation
Jumper Left
Regular output contact OUT4 (operated by Relay Word bit OUT4).
Jumper JMP13 comes in this position in a standard relay shipment.
Jumper Right
Extra Alarm output contact (operated by alarm
logic/circuitry). Relay Word bit OUT4 does not have any
effect on output contact OUT4 when jumper JMP13 is in this position.

CAUTION:
Equipment
components are sensitive to
electrostatic discharge (ESD).
Undetectable permanent damage
can result if you do not use proper
ESD procedures. Properly ground
yourself, your work surface, and this
equipment before removing any
cover from this equipment. If your
facility is not equipped to work with
these components, contact SEL
about returning this device and
related SEL equipment for service.
!
CAUTION:
There is danger of
explosion if the battery is
incorrectly replaced. Replace only
with Ray-O-Vac
®
no. BR2335 or
equivalent recommended by
manufacturer. Dispose of used
batteries according to the
manufacturer’s instructions.
