PANEL CUTOUT FOR
WINDOW MOUNTING
INSTALLATION
The Series DPMW is designed for window mounting in a 2.31˝ (58.4
mm) W x .91˝ (22.9 mm) H panel cutout.
WIRING
The unit is powered by a 4-20 mA loop and the screw terminals for wiring
are located on the back of the adder board marked with + SIG -. The
backlighting requires a 24 VDC power supply and should be connected
to terminals identified with + B/L -.
Note: If backlight supply is not loop supply, ground should be referenced
together.
The Series DPMW LCD Digital Panel Meter is designed with a 3-1/2
digit, high contrast LCD display. The colored segments are available in
red, amber, or green - ideal for viewing at a distance. The Series DPMW
features user selectable engineering units, selectable decimal point
position and adjustable zero and span. The meter accepts a 4 to 20 mA
input signal for pressure, level, flow, and temperature transmitter. A 24
VDC power supply is required to illuminate the colored segments. The
series DPMW can be quickly installed in a window cutout.

OPERATION
Selecting Engineering Units
Four sets of jumper pins are located in the back of the meter, between the
meter and the adder board. Move the jumper to fit over the appropriate pins
which correspond to the desired engineering units. See Figure 1.
Selecting Decimal Point Position
Four decimal point positions are available on the digital panel meter. Move
the jumper to correspond to the desired decimal point location. See Figure
2.
Setting Min/Max Display Value J1, J2, J3 (See Figure 3 & 4):
If:
The minimum display is ≤ 0 or
Minimum display is > 0 and the (maximum display minimum display) >
5; The J1, J2 & J3 should be all set to the top jumper (see Figure 3).
If:
The minimum display is > 0 and the (maximum display minimum display)
< 5; The J1, J2 & J3 should be all set to the bottom jumper (see Figure 4).
MAINTENANCE/REPAIR
Upon final installation of the Series DPMW, no routine maintenance is
required. The Series DPMW is not field serviceable and should be returned
if repair is needed. Field repair should not be attempted and may void
warranty.
