NOTICE

PWR Series

Wet Media Remote Pressure Transducer

Product Overview

The PWR Series remote pressure transducers are designed for dierential pressure applications. The sensors are remotely installed on existing plumbing runs. The PWR is available with either armored (6 ft.) or shielded (10 or 20 ft) sensor cables, and it requires a 15 to 30 VDC or 24 VAC power source to generate its output. The PWR is warranted for a period of ve years.

Installation

Disconnect power from the power source before beginning the installation.

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

1. Mount the housing using the included screws. Avoid locations where excessive vibrations occur.

2. Remove the housing cover by pressing the corner tabs. There are two tabs on each side of the housing. One side is shown below.

Press tabs to remove cover (2 tabs per side)

Installation (cont.)

3. Run the digital control and power source wiring and connect to the left-most terminal block.

4. The sensors and monitor assembly are matched at the factory and calibrated as a unit. They must be kept paired to obtain the

accuracy stated in the product specications. Verify that the serial numbers on the sensors match the serial number on the main housing.

5. Run wires from the remote pressure sensor cables and connect to the pair of 4-terminal blocks at the right side of the board. To

maintain the correct calibration, it is impor tant not to confuse the high side and the low side. To assist, the sensors are labeled, “HI” and “LO.”

6. If the sensors are installed on the wrong side, they can be reversed in one of two ways:

• Swap the cables at the sensor end.

• Swap the headers at the control unit end.

7. Adjust the switches on the board as desired.

8. Reconnect power to the power source. Check that the green LED illuminates, indicating normal operation. If not, check the

wiring.

9. Re-ax the cover onto the housing, ensuring that the cover is properly seated. .Do not operate the PWR without the housing

cover in place.

10. Choose sensor mounting locations that minimize cable length. Use plumbing connections of appropriate “tees” or equivalent,

made of compatible material. Observe safety precautions for plumbing connections. Release pressure from the system. Tighten sensor connections according to ANSI B1.20.3 (hand tighten plus one turn).

Conﬁguration

Test Mode

Test mode overrides the output to full-scale. If the PWR is congured for current (mA) operation, Test mode sets the output to 20.0 mA. If congured for voltage (VDC) operation, Test mode sets the output to 5.0 VDC or 10.0 VDC (depending on the position of the output selection switch).

Status LED

LED Status

Solid Green Normal operation.

Flashing Green Low > High; use port swap jumper or bidirectional mode.

Solid Red Dierential pressure is too high; select a higher pressure range.

Flashing Red Gauge pressure over sensor range; reduce line pressure or replace with a higher range device.

Alternating Red/Green Flash Sensor input is below sensor range. Verify that the sensor is connected correctly.

Auto Zero Function

To automatically reset the output to zero pressure, press and hold the Zero push-button for 2 seconds or provide contact closure on the auxiliary remote tare terminal. To protect the unit from accidental tare, this feature is enabled only when the detected pressure is within 5% of factory calibration.
