quick install

1. Select a location for the installation suitable to the gauge’s physical dimensions
that will allow access to the display and keypad. Plan for a ¼" M-NPT connection
or a hose to a ¼" tting.

2. Thread the gauge onto the tting. Apply tightening torque only to the metal
wrench ats, not to the PD housing. Use a 5/8” wrench. Do not overtighten.

3. Wire the device. See the wiring diagram in this guide.

4. Remove the protective lm from the gauge front.

5. Program the gauge.

DescriPtion

PD analog digital pressure gauges are media isolated, so they can be used with any
gas, liquid, or solid compatible with 17-4 PH stainless steel within the specied
pressure range. The transducer consists of a one-piece, high-strength pressure sensor
that uses no silicone oils, welds, O-rings, or seals. The sensor is coupled to a 4-20 mA
loop powered internal display and keypad. The keypad controls setup and operation
of the sensor as described below.

installation anD Wiring

Allow space to turn the PD Analog onto the pipe or tting during mounting. The PD is
delivered with the connector attached to the device.

Electrical

Select a loop power supply voltage and total loop resistance such that when the loop
current is 20 mA, the gauge will have at least 7.5 VDC at its terminals. Too large a loop
resistance will cause the gauge output to "limit" or saturate before reaching its full
20 mA output.

The minimum loop supply voltage is calculated from the formula:

V

= 7.5V + (20mA * total loop resistance).

If the loop voltage drops too low, the PDxAM will display the LOW LOOP icon. At this
time, all calibration functions are disabled.

The LCD is loop-powered. If no voltage is applied, or if the connector is removed, the
display will be blank.

test

To switch the PD into Test Mode, press and hold down the TEST button. The Test Mode
allows setup and testing of the output voltage without altering the system pressure.
To change the test output level, press and hold the TEST button, and press the CALIB
button while holding TEST. Each time the CALIB button is pressed, the test level
output increases by 2 mA.

Notes:

Only attempt Span ca libration if the user has access to a pressure reference of known accuracy. Use

calibration equipment swith at least four times the gauge accuracy. Perform Zero calibration
before span calibration.

If the user tries to calibrate the unit beyond ±10% of the factory calibratio n, the display will read

“ERR” indicating an erroneous calibration.

To cancel calibration, press and release the CALIB button.

To restore factory calibration, repeat steps 1 and 2, then h old the ZERO button for 3 seconds, u ntil

the display reads “FAC.”

1. Press to select pressure units.

2. Press and hold for 3 seconds, until display alternately
reads “CAL” and the calibration pressure (e.g. “CAL” and
“500” to calibrate at 500 psi).

3. Connect the gauge port to a pressure reference of known
accuracy. Apply pressure level selected in Step 2.

4. Press and hold the CALIB button for 3 seconds until
display reads “DONE.” Calibration is now complete.

Open gauge por t.

The PD can be re-zeroed without aecting the span calibration. The gauge port must
be open with no pressure or vacuum applied.

Perform this step when pressure uni ts show in the display (not mA). Zero calibration is retained
after unit is turned o .

current outPut calibration

The current output on the PD analog pressure gauge has been set at the factory.
These setting will not normally need adjustment. Perform these steps only if
necessary.

1. Press to select the mA units.

2. Connect the leads to an accurate current measurement
device.

3. Press and hold for 3 seconds, until the display ashes
between “CAL” and “4.00.” Set the loop current to 4.00
mA

4. Press TEST to decrease the output by 0.01 mA. Press UNITS
to increase the output. While the output will change, the
display will not.

5. Press and hold for 3 seconds to accept the calibration at

4.00 mA. The display will change to “CAL” and “20.00.”

6. Repeat steps 3 through 5 to calibrate at 20 mA. Display will now read “DONE.”

Notes:

To cancel calibration changes, briey press and rel ease the CALIB button.

To restore factory calibration, repeat step 3 on ly, then hold the ZERO button for 3 seconds, unti l the

display reads “ FAC.”
