Description
The DP470V is designed as a fully programmable
digital process indicator and miniature datalogger. The unit
will accept either 0-10 Vdc or 4-20 mA input and is fully
scalable from –999 to +9999 display counts. Scaling and
decimal point placement is selectable through the front panel
keys. PROGRAM (P) and PROCESS (L) status are indicated
by a green, .4" seven segment LED located to the right of the
main display.
The displays are 0.56" in-line red LED type. The
menu driven display prompts and 14-segment alphanumeric
characters make programming simple. A single dash (-)
displayed at the left of the readout indicates a negative
reading. Positive readings are inferred (no dash displayed).
Overload is indicated by an 'OL' on the display. Plus OL
(+OL) indicates a positive over range condition. Negative (OL) indicates a negative over range condition. The DP470V
Series is powered by a 100-240Volt, 50-400Hz AC source and
uses a switching power supply for maximum input power
flexibility.
Serial communications is standard, either RS232 or
RS485. This bi-directional serial port allows the user
complete program set-up, programming and operational
capability. All controls and features are selectable through the
front panel. The front panel lens may be removed to install or
remove the program lockout jumper or fine tune the analog
output if necessary. Power and serial connections to the meter
are made to the rear of the instrument via a removable Euro-
1
style terminal block. Sensor connections are made by screw
terminals also on the rear of the instrument.
Minimum and Maximum values are always available
for viewing. On the Basic model (no options), the information
is accessible through the front panel menu system.
Configuration settings are stored in on-board memory and are
not affected by power loss.

Installation
Panel Installation
1. Prepare a mounting panel cutout by cutting a rectangular
hole (3.62” +0.02/-0.0” X 1.77” + 0.02/-0.0”) in the
desired location (see Figure following page). The
maximum panel thickness is 3/8 inches.
2. Remove the mounting bracket from the instrument
housing by removing the two screws on the rear of the
indicator.
3. Remove the pluggable terminal block located at the rear of
the unit and wire the input power and RS232 or RS485
wires. If an option board is installed in the indicator,
remove
the connector and make the appropriate connections (refer
to
diagram on page 6).
WARNING!
Dangerous voltages are exposed at the screw
terminals. Always remove power before working in
this area for rewiring, disassembly, and all other
activities that involve proximity to electrical
circuitry. Allow at least 10 minutes prior to
working on the unit.

4. Install the indicator in the panel cutout from the
front side of the panel. Be sure the instrument is
right-side-up. See figure on following page.
5. Reinstall the mounting bracket on the indicator.
Tighten the bracket screws to achieve a snug fit
against the panel. Avoid distorting or cracking the
housing by not over- tightening the bracket screws.

For easy installation, remove the pluggable terminal block
located at the rear of the unit. Connect the input power and
RS232 or RS485 wires to the wire entry locations beneath and
perpendicular to the plug-in direction according to figure
below.

Multiple input current configuration:
Remove power and snap off the front panel lens. Leave the
keypad attached to the display board, as it will be required to
enter the calibration menu. Remove the rear pluggable
connectors from the rear of the indicator and slide the main
board electronics out of the case from the front. (Gently lift
the display board above the catch located on the bottom of the
inside of the plastic housing while pushing on the rear male
7
connector on the rear of the main board assembly.) Locate the
three-pin header near the rear of the unit. Move the jumper
from position A to position B. Carefully re-install the
electronics back into the housing and wire the inputs
according to the diagram on page 7.
Note: If the multiple input option is used to switch 4
to 20 mA inputs, note that loop continuity will not
be maintained when changing channels.

PGM
Operation
Your indicator is programmed by a series of menu driven
displays that are operated by three front panel pushbuttons;
Program-PGM, Arrow-∆, and Enter-ENT.
ENT
PROGRAM ARROW ENTER
Addressing the main menu items configures the indicator.
The indicator has a program lockout jumper located behind
the front panel lens. Removing the jumper will prevent any
front panel changes of the indicator programming. The
indicator may still be programmed via the computer interface.
Note: When using the DP470 Viewer Software, the front
panel keyboard is automatically disabled.
The basic unit has three main menu items-
1. SCAL: Sets up desired display counts
including decimal points.
2. MATH: Selection enables viewing of either
minimum or maximum value.
3. CAL: Used for calibrating the voltage or
current limits.
9
The following menu items are displayed only when the
appropriate option is installed-
4. ALM1/ALM2: Sets relay trip points to
programmed values, hysteresis and delay.
5. AOUT: Programs the indicator to translate the
display to a proportional analog voltage or
current output.
6. MULT: Configures indicator for multiple
voltage or current inputs
Pressing the PGM key allows you to access any of the menus
listed above by placing the indicator in program mode,
indicated by a ‘P’ lit to the right of the display. Placing the
indicator in PGM mode will prevent the indicator from
performing measurements. Any alarm monitoring will be
disabled.
If the PGM key is pressed anywhere within a menu,
the menu reverts to the previous menu level. Repeatedly
pressing the PGM key will return the indicator to the display
mode. Choices within a menu are viewed by pressing the
ARROW key. A menu item is selected by pressing the ENT
key for selection, or edited by pressing the ARROW key.
Generally, the ARROW key allows you to scroll horizontally
through a selection of choices while the ENT key enables you
to make selections and move down vertically to the next menu
item.
