Series DPMX Extra Large Digital Panel Meter
Specifications - Installation and Operating Instructions
Bulletin G-62
The Series DPMX Extra Large LED Digital Panel Meter can easily be
viewed from across a room or in dark areas. The 2.3” LED segments are
available in red, green, or blue. These panel meters come equipped with
a universal power supply and user selectable process inputs to fit most
applications. The Series DPMX includes a mounting bracket that can be
adjusted up to 180°.
INSTALLATION
The Series DPMX is designed to be bezel mounted or gimbal mounted.
Mounting brackets are included in the box.
BEZEL MOUNT
Remove the two U-brackets from the back of the panel meter. Slide the
unit through the panel from the front. Next, attach the U-brackets to the
rear and tighten the four retaining bolts.
See Figure 1 for dimensions of the cutout.
Figure 1
GIMBAL MOUNT
If the panel meter is to be gimbal mounted, remove and discard the two
U-brackets from the back of the panel meter. Fasten the gimbal brackets
to the mounting surface using appropriate hardware. Lastly, fasten the
panel meter loosely to the gimbals using the thumbscrews. Note that
detents are provided on both sides of the case. Adjust the meter to the
desired viewing angle and securely tighten the thumb screws.
WIRING
The unit accepts signal inputs of 200 mVDC, 2 VDC, 5 VDC, 20 VDC,
10 VDC, and a 4 to 20 mA DC loop. The screw terminals for wiring are
located on the back of the adder board beneath the cover. The cable
clamps must be unfastened to access the screw terminals. In order to
reduce electrical noise, install the line voltage and the process signal
through separate cable clamps as shown in Figure 2.
Figure 2
On the terminal cover, remove two thin break out sections that best
match the diameter of the wiring cables being used.
