PRECAUTIONS

• Do not switch pressure range and output mode when power is on. Make sure to power oﬀ the unit ﬁrst, then set the DIP Switches to the correct positions and then power on the

transmitter.

GENERAL INFORMATION

The DLP Series is based on a piezoresistive, silicon sensing element which senses Dierential Pressure and provides an analog output. Field selectable analog outputs include 0-5 and 0-10 VDC, or 4-20 mA which correlate to a uni or bi-directional pressure range from 0-0.1” up to 0-40” of water column, depending on your model selection. Each unit has up to 8 eld selectable, uni or bi-directional ranges (see Figure 6 p. 3).

CORDGRIP / 1/2 “ CONDUIT FITTING

MEDIA

The DLP can be used to monitor the dierential pressure in any application that uses dry air or inert gas.

Mounting

Find a suitable location for the enclosure. The DLP has 2 two mounting holes located on the top and bottom anges. Drill pilot holes for the (2) #8 x 3/4” self-drilling screws(supplied). Use the enclosure ange as a guide, or use the dimensions listed in Figure 1. Mount the unit vertically with the brass ttings pointing towards the ground. This ensures that any condensation that may form in the tubing does not have an eect on the pressure sensor. If mounting the unit horizontally, a slight zero shift may occur and care must be taken to prevent moisture from building up in the sensor.

DIN RAIL MOUNTING (Optional)

Attach the DIN Rail Mounting accessory to the back of the enclosure using the two screws provided. To mount the sensor on the DIN Rail, place the bottom of the DIN Rail Clip into the 35mm DIN Rail and push the unit upward to engage the spring clip. Now press the top of the unit back until it locks into place - see

FIGURE 2 (p.1).

PITOT TUBE INSTALLATION

(Optional)

Slip the rubber washer over the threaded end of the pitot tube, keeping the washer as close to the threaded end as possible. Fasten the pitot into the threaded insert on the back of the enclosure. Press the rubber washer against the enclosure - see FIGURE 3.

Tubing Setup When Pitot Tube is Installed

Units will be shipped with silicone tubing attached to the high and low pressure barb ttings. The silicone tubing will need to be removed from the High Pressure (H) barb tting and secured onto the pitot tube barb tting. This will leave the high pressure barb tting open to atmosphere, and the Low pressure barb tting remaining at default setup.

Pressure Connections

The recommended connection tubing is ¼” O.D push-on tubing (1/8” to 3/16” I.D.). For best results, all tubing lengths should be limited to a maximum length of 75 feet (23 meters). Longer runs will aect the response time.

WIRING

PRECAUTIONS

FIGURE 6: SW1 and SW3 OUTPUT

SWITCHES

• Remove power before wiring. Never connect or disconnect wiring with power applied.

• When using a shielded cable, ground the shield only at the controller end. Grounding both ends can cause a ground loop.

• It is recommended you use an isolated UL-listed class 2 transformer when powering the unit with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may result in

damage to any device powered by the shared transformer.

• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DC Transorb or diode, connects to the positive side of the power supply. Without these snubbers, coils produce very large voltage spikes when de-energizing that can cause malfunction or destruction of electronic circuits.

Open the cover of the enclosure. ACI recommends 16 to 26 AWG twisted pair wires or shielded cable for all transmitters. Twisted pair may be used for 2-wire current output transmitters or 3-wire for voltage output. Connect the wires to the unit’s nger push-button terminal blocks. Each DLP unit can be congured to three output signals: 4-20 mA, 0-5 V or 0-10 V. Use the Wiring Connections and diagrams to determine the proper wiring for your application. See TABLE 1 (p.3) for Output Mode and Output Signal switch positions.

Note: When using 1/2” conduit, the strain relief tting must be removed from the enclosure.

Note: Make sure that any conduit or metal ttings do not come in contact with the circuit board.

ZERO FUNCTION

FIGURE 8: AUTO ZERO BUTON - SW2

The DLP unit should be “ZEROED” before pressure is applied to the unit. The zero button is used to cancel out any osets caused by installation and sensor drift. The Zero adjustment must be performed with NO pressure applied to either side of the sensor.

AUTO

ZERO

SW2

Remove the tubing connected to the H(High) and/or L(Low) pressure ttings. Push “ZERO” button for more than three seconds before installation or whenever necessary.

For units with LCD display, “AUTOZERO” icon will be on when the unit enters zero mode. If zeroing process is successful, the “AUTOZERO” icon will ash twice.

PRESSURE RANGE SELECTION

If a custom calibrated pressure range is ordered, DO NOT change the Pressure Range Selection DIP switch settings. Table 2 lists ACI’s 12 standard model #’s.

UNIDIRECTIONAL AND BIDIRECTIONAL MODE

The DLP can operate in either unidirectional mode (0 – X inWC) or bidirectional mode (± X inWC). Each unit could have up to eight eld selectable, uni or bidirectional ranges.

CAUTION

• See TABLE 3 for your DLP model’s maximum pressure.

• DO NOT switch pressure range or output mode when POWER is ON. Make sure POWER to the

unit is OFF. Failure to do so WILL NOT ALLOW any new switch settings to take place.

• Choose diﬀerential pressure range based on the expected diﬀerential pressure in your

application. Move switches to the correct positions and THEN POWER ON the transmitter.

Unidirectional Mode

• DIP switch SW3 position ve set at UNI side.

• DIP switch SW3 positions one and two are for Pressure Range Selection

Bidrectional Mode

• DIP switch SW3 position ve set at BI side.

• DIP switch SW3 positions one and two are for Pressure Range Selection.

Note: In Bidirectional mode, a value of 0 inWC will have an output equal to 50% of the output signal range

(12mA, 2.5V, 5V).

ADDITIONAL LCD FEATURES

LCD Engineering Units Adjustment

This option is ONLY for units with LCD display. Switch DIP switch SW3 position three to select Pa or inWC. If switched with power on, unit change will not take place until power is cycled.

“Out Of Range”

“OUT OF RANGE” icon will be on when dierential pressure is over or under the minimum or maximum pressure range selected. If a DLP unit is outputting “OUT OF RANGE”, please turn o the unit immediately, and check the pressure input with a gauge or other test instrument. Once the pressure has been veried, set the Pressure Range Selection DIP switch to the proper positions based upon your maximum expected dierential pressure.

CALIBRATION

DLP utilizes a digital pot for Span calibration and is factory set. There is no Span potentiometer for adjustment. In the event you require Span calibration, the unit must be sent back to ACI.

The Oset can be adjusted using the Auto Zero function discussed on pg 4. Drift is a function of stress relaxation over time and this results in the oset shifting, and not the span . Periodically re-zeroing the device will eliminate the eect of drift.
