Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Find a suitable mounting position near the location to be measured. Mount the PW housing using the self-tapping screws
provided.
2. Remove the lid from the housing to reveal the board. Wire the PW terminals to the power source and to the digital control
system as shown. Configure the jumpers for desired operating parameters. Replace the cover.

4. Connect the other ends of the tubing to a pipe or duct, across the pump, filter, or other pressure differential.
Notes
During operation, the LCD shows two pressure values. The value adjacent to the PSID label shows the differential pressure, while
the value adjacent to the PSIG label shows the high port gauge pressure. The gauge pressure value is read from the high port if DIP
switch #5 is in the Normal position. If this DIP switch is in the Port Swap position, the PSIG value is read from the low port, and the
value is usually a negative number.
This product uses a half-wave rectifier power supply. If the installer is using a transformer to power the device, do not use the
same transformer to power other devices utilizing non-isolated full-wave power supplies.
Optional: Connect the Zero terminals to the digital output (contact closure) of the control system. The Zero input is for dry-contact
only. Do not apply voltage to the Zero terminals.
To use the auto zero function, press and hold the Zero button for two seconds or provide contact closure on the auxiliary 'Remote
Zero' terminal to reset the output to zero pressure. To protect the device from accidental zeroing, this feature is only enabled when
the detected pressure is within 5% of factory calibration.
