Sensors

 PRECAUTIONS

• Remove Power Before Wiring. Never Connect Or 

Disconnect Wiring With The Power Applied. Do Not 
Allow Live Wires To Touch The Circuit Board. 

• An Isolation Transformer Is Recommended When 

Powering The Device With 24vac. 

• Do Not Run The Wiring In Any Conduit With Line 

Voltage. 

• Failure To Wire Devices With The Correct Polarity 

When Using A Shared Transformer May Result In 
Damage To Any Device Powered By The Shared 
Transformer. 

• Do Not Remove The Cover. All User Features Are 

Accessible From The Outside Of The Unit 

MOUNTING

Using the two #8 x 3/4-in. self-drilling mounting screws, 
or the integrated 35mm DIN rail clip on the back, mount 
the unit vertically with the brass fittings pointing toward 
the ground.

Attach the unit to the mounting surface using the two 
mounting openings located on the top and bottom 
flanges. This ensures that any condensation that may 
form in the tubing does not have an effect on the pressure 
sensor. If mounting the unit horizontally, a slight zero shift 
may occur and care must be taken to prevent moisture 
from building up in the sensor.

WIRING

Shielded cable with 16 to 22AWG conductors is 
recommended. Use the Wiring Connections table below to 
determine the proper wiring for your application. Insert the 
wire into the depluggable terminal block sockets and 
tighten the screws. In some circumstances, it may be 
easier to remove the terminal blocks while connecting the 
wires.

NOTE:

When using a shielded cable, be sure to connect 
only (1) end of the shield to ground at the control-
ler. Connecting both ends of the shield to ground 
may cause a ground loop. When removing the 
shield from the sensor end, make sure to properly 
trim the shield to prevent any chance of shorting.

Pressure Connections

The recommended connection tubing is ¼” push-on 
tubing (1/8” – 3/16” I.D.). Keep the tubing runs as short as 
possible so as to not affect the response time.
