6. 5BMaintenance/Repair
6.2. Replacing Antenna
Step
Honeywell recommends that the sensor be removed from service and moved to a clean area
1
before servicing. Use care to avoid rotating the input shaft, causing the internal slip clutch to
slip.
If applicable, remove two T-15 TORX screws (1) and cover lock clamp (2).
2
Place a large screwdriver or other flat tool across the two tabs on the cover (3). Unscrew and
3
remove the cover.
Unplug cable from potentiometer (4) to Jack J2 on battery board, by compressing the locking
4
clip and pulling outward. See Figure 12.
Loosen the two battery holder retaining screws (5) (closest to the batteries). The screws are
5
captive.
ATTENTION
NOTE: Use caution in disconnecting the antenna cable, as applying too much pressure can
damage the connectors.
NOTE: Antenna location 1 is illustrated. For sensors using antenna locationi 2, the antenna
cable routing will be through the opposite slot in lower mounting plate.
Remove the sensor/battery module (6) from the sensor body and carefully disconnect the
6
lower connector of the antenna jumper cable (7) from the right angle connector on the antenna
cable (8). See Figure 12.
Loosen two screws on lower mounting plate (9) and raise the plate sufficiently to allow the
7
release of the antenna's cable. See Figure 12. Lower the lower plate, insuring that the white
end bearing on the plate fits back into the shaft assembly. Temporarily tighten screws.
Using a 1.5 mm (approx. 1/16") allen wrench, loosen the locking set screw (10) at the antenna
8
base. Note that its position may differ from illustrated. Unscrew the antenna from the sensor.
Remove the antenna (11) and its connector from the sensor.
Lubricate the new antenna's threads and O-ring (12) with a Silicone Grease such as Dow
9
Corning #55 or equivalent. Feed the new antenna's connector (8) through the antenna hole to
the front of the sensor. Do not connect to sensor module cable yet. Screw new antenna into
sensor body until finger-tight. For elbow type, back off 180 degrees to permit adjustment later.
Loosen two screws on lower mounting plate (9) and raise the plate sufficiently to allow the
10
insertion of the antenna's cable back into the notch in the plate. See Figure 12. Tighten
screws and torque to 0,4 – 0,6 N-M (3.5 – 5.3 Lb-in).
Use tweezers or needle nose pliers to grip the right angle antenna connector, hold the lower
11
end of the antenna jumper cable steady, and carefully press the connectors together. A distinct
click should be heard as the connector is fully seated.
Insert sensor/battery module. Tighten the two captive battery module screws. Torque screws
12
to 0,4 – 0,6 N-M (3.5 – 5.3 Lb-in).
Plug cable from potentiometer (4) into Jack J2 on battery board. Note that the potentiometer
13
cable goes to the outside of the antenna cable. See Figure 12).
