Differential Pressure Transducer Multi-Range
DP150 Series Installation Guide
Introduction
The Johnson Controls® DP150 Series senses differential
pressure over a multi-sense range. Every DP150
transducer is calibrated and tested before shipment to
guarantee performance for all pressure ranges. The DP150
is available in four versions that have field-selectable
range capability through slide switch and jumpers. See
Table 1. Units are either in inches (in.) of water column
(WC) or Pascal (Pa)

DP150

Compatibility
Use the Johnson Controls DP150 transducers with air or
nonconducting gases.
Note: Use with liquids or corrosive gases will
damage the unit.
The operating temperature limits of the DP150 are as
follows:
• Operating temperature: 32°F to 122°F (0°C to 50°C)
• Compensated temperature range: 32°F to 122°F (0°C to
50°C)
Mounting
About this task:
Mount and calibrate the DP150 in a vertical position for
quick and easy installation on ducts, walls, or ceilings
and in control rooms. The DP150 comes calibrated as if
mounted to a wall or a perpendicular surface to the floor
or ceiling. If you mount the DP150 in another orientation,
the unit may show a slight zero shift. See Zero adjustment
to correct the zero shift.
Installation
About this task:
The DP150 has a removable terminal block for easy
wiring. For CE compliance, you require a shielded cable
with both ends correctly grounded.
To install the DP150 transducer, complete the following
steps:
1. Wire and turn on the unit. See Figure 2 for 2-wire
configuration and Figure 3 for 3-wire configuration.
2. After you complete wiring requirements, turn on
the DP150.
3. Turn on the LCD unit. Display toggles through all
existing setup parameters.
4. The display indicates the pressure. Units are either
in inches of WC or Pa.
5. Select pressure range. Use the slide switch
multiplier and JMP4 jumper to set the appropriate
full-scale range. See Figure 4.
Note: A to D is WC, E to H is Pa. LCD will
indicate the selected range. To select E-H
position, move JMP to Pa position.

6. Select unidirectional or bi-directional mode.
7. Select current, mA, or voltage: 0 VDC to 5 VDC or 0
VDC to 10 VDC output range. See Figure 4.
Note: If you use 0 VDC to 5 VDC or 5 VDC to
10 VDC outputs, set the mA/volt switch to volt
position.
Figure 4: DP150 range specifications
8. While at zero pressure, press and hold the zero
button until you see 0. Release the zero button to
automatically reset the output to zero.
Optional configuration
About this task:
For optional configuration of the DP150 transducer,
complete the following steps:
1. Press and hold the zero or config button, until you
see 0.
2. Hold down for 7 secs until you see the Conf screen.
3. Release button and screen reads Filt.
4. Hold down button until Filt flashes. Filt is a
sampling filter with 4 options: Nor (normal), SLo
(slow), FAS (fast), and Off (no filter). See Table 2.
5. Press the zero or config button to cycle through the
options.

6. To select an option, press and hold the button until
the screen flashes.
7. After selecting the filter, the screen shows Filt.
Cycle through the options and press Done.
8. Press the button until it flashes. The sampling filter
increases the sample size before it updates the
output and the display.
9. For noisy pressure environments, increase the
sample size to slow the setting. For faster updates,
change the setting to fast or off. The default setting
is normal.

Zero and span adjustment
Use the zero or span button to recalibrate the unit in the
field. You can calibrate the unit in any of the pressure
ranges.
Figure 5: DP150 transducer
Zero adjustment
About this task:
To make the zero adjustment, complete the following
steps:
1. With the unit at zero differential pressure, press
and hold the Zero or Config button until the 0
display blinks.
2. Release the button. The display briefly shows ---- to
re-zero the unit.
3. If the re-zero is successful, the display shows good.
The new zero value is automatically stored in
nonvolatile memory.
4. If the re-zero is unsuccessful, the display shows
bAd. This usually occurs because the re-zeroring
pressure is more than ±10% off of the sensor range
factory setting.
Span adjustment
About this task:
To make the span adjustment, complete the following
steps:
1. Perform Zero adjustment before Span adjustment.
2. Use a reference grade calibrator to apply positive
full-scale differential pressure.
3. Press and hold the Zero or Config button until the
display shows 0, and the display stops blinking and
shows Conf.
4. Release the button to get into the Configuration
menu. The first selection is Filt for the Filter setting.
5. Press but do not hold the button until the display
shows -SP- for the Set Span setting.
6. Press and hold the button until the display blinks to
select it. The display shows yes.
7. Press and hold the button until the display blinks
and then release the button. The display shows ---
briefly to re-span the unit.
8. If the re-span is successful, the display shows good.
The new span value is stored automatically in
nonvolatile memory.
9. If the re-span is unsuccessful, the display shows
bAd. This usually occurs because the re-zeroring
pressure is more than ±10% off of the sensor range
factory setting.
Repair information
If the DP150 transducer fails to operate within its
specifications, replace the unit. For a replacement
assembly, contact the nearest Johnson Controls
representative.
