Sensor Connections
For convenience, it is recommended you connect the Primary or
controlling sensor to SENSOR 1 position as shown in
figure III.H.1.
CAUTION: The sensor connectors require only a small screw-
driver or a pen to push on the release lever. Follow the color
code as marked. The release levers may be broken or damaged
if not pushed straight toward the CB. DO NOT push the release
levers sideways.
3. ALARM/CONTROL CONFIGURATION
Sensor Switch
As shipped from the factory, the 3SR Module is configured so
that only the Primary or First switch position “S1” is set to alarm/
control, figure III.H.2. If your particular application requirements
are different, the following will help you to reconfigure the alarm/
control function to another sensor or add a controlling sensor.
Pick the appropriate scenario below.
NOTE: the setpoints will not change nor are they separately
adjustable for each sensor.
If adding an alarm/control sensor.
1. Locate the 8 position select switch on the 3SR Module.
2. Set appropriate select switch UP or ON, i.e. to add S3
sensor, set switch marked S3 UP or ON, see
figure III.H.3.
If changing alarm/control from one sensor to another, i.e. S1 to
S2 sensor.
1. Locate the 8 position select switch on the 3SR Module.
2. Set the S1 select switch in the DOWN or OFF position.
3. Set the S2 select switch in the UP or ON position, see
figure III.H.4.
To disable the Sensor alarm/control function completely.
1. Locate the 8 position select switch on the 3SR Module.
2. Set all X prefixed and S prefixed select switches in the
DOWN or OFF position, see figure III.H.5.
Range Switch
As shipped from the factory, the 3SR Module is configured so
that only the Primary or First switch position X1 is set to alarm/
control, figure III.H.6. If your particular application requirements
are different, the following will help you to reconfigure the alarm/
control function to another range or add a controlling range. Pick
the appropriate scenario below. The setpoints will not change
nor are they separately adjustable for each range.
NOTE: The Range Switch is labeled:
