Required Tools

• Drill with 13/32-inch (10.3 mm) bit

• Power screwdriver with standard screw chuck

or medium flat-blade screwdriver

• Wire cutter/stripper

Expected Installation Time

45 minutes

Prerequisite

The appropriate field wiring, within the maximum

wiring length, should be routed through the conduit.

Installation

NOTE: All wiring must comply with National Electric

Code (NEC) and local regulations.

1. Drill a 13/32-inch (10.3 mm) hole into the duct at

the desired location of the sensor. See Figure 1.

2. Remove the conduit box cover and remove

gasket. Assemble gasket onto sensor assembly.

See Figure 1.

3. Insert the sensor tube into the hole.

4. Hold the conduit box against the duct and secure

the sensor to the duct with the two No. 18-8 self-

tapping sheet metal screws supplied with the

sensor.

5. Attach the flexible conduit and field wiring to the

conduit box. Ensure that the conduit and field

wiring have enough length to allow the

installation/removal of the sensor assembly.

Figure 1. Duct Point Sensor Installation.

6. Connect the field wiring to the transmitter with the

positive (+) 26V supply lead to the PWR wire and

negative signal lead to the SIG wire. See Figure

2 and Table 1.

NOTE: For 544-560-XX

variants, connect the

field wiring to the transmitter with the

positive (+) 26V supply lead to

terminal No. 1 and the negative

signal lead to terminal No. 2.

7. Replace the conduit box cover.

8. Connect the field wiring at the controller as

shown in the wiring diagram. See Figure 2 and

Table 1.

The installation is now complete.
