PANEL CUTOUT FOR
WINDOW MOUNTING
Series DPMW LCD Digital Panel Meters
Specifications - Installation and Operating Instructions
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.
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 -.

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.
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).
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).
