QUICK INSTALL

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Mount the PXR onto DIN rail.

2. Congure the tubing for dierential or static pressure monitoring.

PXR

OPERATION

PX Series devices employ ceramic capacitive sensors and sophisticated temperature compensation circuitry to achieve accurate pressure readings in dry media applications. For best results, allow an initial warm-up period to ensure accuracy at the lowest pressure ranges.

The PXR has a ZERO pushbutton to reset the output and display to zero pressure. Press and hold the ZERO pushbutton for 2 seconds or provide contact closure on the “AUX ZERO” terminal. To protect the unit from accidental zero, this feature is enabled only when the detected pressure is within about 0.1 in. W.C. (25 Pa) of the factory calibration. The optional LCD displays the current reading and the selec ted units. “SET” appears each time a selection is made. “OVER” appears when the measured pressure is over the device’s range.

INSTALLATION

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

Disconnect power to the panel.

1. Select a location in the panel, near the area to be monitored. Mount the PXR onto DIN Rail.

INSTALLATION GUIDE

Wire the PXR: connect the transmitter to the control system and the power supply as indicated below. Optional: Connect the ZERO terminals to the digital output (contact closure) of the control system.
