Wiring
Accessories for the CSE-1102/1103 are the following
air flow sensing probes:
• HFO-0015, 4 inches (102 mm) long
• HFO-0016, 6 inches (152 mm) long
To install either probe:
1. Drill holes in the ducting for the 1/4" (6 mm) OD
sensor probe and the mounting screws.
2. Insert the sensor probe through the mounting
plate and into the duct.
3. Turn the sensor probe so that air flows into the
sensor’s opening.
4. Attach the mounting plate to the ducting using
screws.
5. Connect to the probe using 3/8" (9 mm) OD
flexible tubing or a compression fitting to 1/4" OD
copper tubing.
Optional HFO-001x Sensor Probe
Setpoint Adjustment
NOTE: To properly calibrate an air switch, a
digital manometer or other measuring
device should be used to confirm the actual
setpoint.
The adjustment range is 0.05 ±0.02 to 12.0" wc. To
adjust the setpoint:
1. Turn the adjusting screw counterclockwise until
motion has stopped.
2. Turn the adjusting screw clockwise 4 complete
turns (to engage the spring). From this point, the
next (up to) ten turns are used for the actual cali-
bration. Each full turn represents approximately
1.2" wc. For example, 2-1/2 turns (after the initial
4 clockwise turns) equals about 3" wc (2.5 turns x
1.2" wc per turn).
Before pressure is applied to the diaphragm, the
SPDT switch contacts will be in the normally closed
(NC) position. The snap switch has screw top ter-
minals with cup washers. Wire control and alarm
applications appropriately.
Maintenance
No routine maintenance is required. Each compo-
nent is designed for dependable, long-term reliabil-
ity, and performance. Careful installation will also
ensure long-term reliability and performance.
