WIRING
•
Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage.
•
Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
•
Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wire diagram for the applicable power
supply and output signal type as shown in Figure 8.
•
Select desired signal output type (mA or Vdc) by setting switch on PCB to desired output configuration (mA or V) as shown in Figure 6.
•
If mA was selected, no further Output set up is required. If VOLT output is selected in Figure 6, Set DIP switch for desired voltage output as
shown in Figure 7. Setting one DIP switch to ON position will select the output (10V, 5V or 1V). NOTE: Only one of the Voltage select switches
should be in the ON position.
•
Connect the DC positive or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply Common is connected
to the COM terminal. The device is reverse voltage protected and will not operate if connected backwards. It has a half-wave power supply so
the supply Common is the same as the signal Common. See Figure 8.
•
The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper connection before applying
power as shown in Figure 8.
•
If installed, the resistance temperature output is available on the two terminals labeled TS1 and TS2 as shown in Figure 9.
•
The RH and Temperature sensor PCB can be field replaced by removing filter at end of Duct Probe. Please refer to the product submittal sheet
for replacement sensor selection.
