Dwyer Instruments DPMW Series 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 -.
Note: If backlight supply is not loop supply, ground should be
referenced together.
