PWR Series
Wet Media Remote Pressure Transducer
Product Overview
The PWR Series remote pressure transducers are designed for differential 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 five years.

Approvals
RoHS, IP65, CE
* VFD systems and system wiring generate fields that can disrupt electrical devices. Ensure that these fields are minimized and
are not affecting the sensor or sensor wiring.
** F.S. is defined as full span of selected range.
*** Accuracy combines linearity, hysteresis, and repeatability.

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)

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 specifications. 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 important not to confuse the high side and the low side. To assist, the sensors are labeled,
“HI” and “LO.”

* “Off” position is the default setting for all DIP switches.
** Ignored in mA mode.
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-affix 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
TM
Test Mode
Test mode overrides the output to full-scale. If the PWR is configured for current (mA) operation, Test mode sets the output to 20.0
mA. If configured 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
Differential 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.
