1. Safety instructions
•Read instruction manual carefully before operating the device! Keep for later
reference.
•Mounting and installation must be carried out by suitably qualified and competent
persons only.
•When working on the device hazardous voltages must not be connected to
the device! The terminals J1-J12 are not isolated from the measuring
circuit.
•The device must not be used as the only protective device or protective
shutdown.
•The device is not intended to protect persons or facilities against harm. Specific
devices must be used to guarantee safety (protection relays, cut-off switches,
etc.).
•When connecting switches to the terminals J1-J6, only switches must be used
whose isolation voltage is at least twice the maximum occurring measurement
voltage. For example, when measuring 30;V DC switches must be isolated for at
least 60;V.
•Do not open the housing!
•Do not use the device in the presence of explosive or flammable substances!
•ll cables carrying hazardous voltages must be secured with external separators.

3. Intended use
•Indoor use non condensing, non corrosive.
•Panel mounting.
•Failure to comply with these instructions will void all guarantee and warranty.
•In operation, supply the device preferably via screw terminals with 12 to 24;V
C/DC. If the device is supplied via USB in operation, USB supply voltage must
be at least 5;V.
4. Description
The measurement modes analogue signal 0/2 to 10 V and 0/4 to 20 m DC are
supported. The multi display with RGB backlight is able to display up to four
parameters simultaneously. Thresholds can be associated with individual warning
colours. The unit can be switched between measurement modes via an external
switch. Minimum and maximum values are recorded and can be displayed and reset
via jumper or an external switch. Measured values are recorded over a timespan of
three minutes up to 14 days. The timebase as well as the display of the measuring
history can be activated by an external switch. The measured values remain stored
as long as the device is supplied with voltage.
The following parameters can be adjusted using the USB configuration software
“Digalox Manager”: scale endpoint, scale caption, display style (pointer, tachometer,
bar graph, and more), splash image, backlight colour, thresholds for alarm output,
threshold warning colour (light, blink), hysteresis, and more. Recorded
measurement values can be read and a continuous transmission of the actual
measuring value can be enabled. Using the software, values can be viewed and
exported as CSV.

6. Mounting
Carefully insert the device into the panel
cut-out. Insert the mounting bracket from
the back and push towards the panel until
the device sits tight. Make sure the
mounting bracket is snapped into the side
of the housing. To ensure IP65 protection
(dust and water jet) when mounting in a
front panel, use optional gasket
(separately available).

8. Configuration
The device can be configured via jumpers manually or with the corresponding
software “Digalox Manager” via USB interface. When configuring via jumpers the
basic settings can be made independently of a PC. The configuration with the
software “Digalox Manager” allows full functionality.
Configuration via jumpers
measurement mode can be selected by setting jumpers at J4-J6 according to the
table “Measurement mode”.

Configuration via USB interface with software “Digalox Manager”
Connect the device via USB to a
computer. fter the automatic driver
installation connect the device to the
“Digalox Manager”. Then settings
can be made on the different tabs
and saved in the device.
Please note that the measurement mode selected in “Digalox Manager” is displayed
only until the power supply of the DPM72 is interrupted.
In further operation, the device always shows the measurement
mode that is selected by the jumpers J4-J6
(see table “Measurement mode”),
in case of a multi display style additionally the following measuring modes.

9. Other settings
The following functions can be activated independently during operation by short-
circuiting connectors J1-J3, e.g. using a jumper or switch:
J1 Graphical historic data display
To activate the graphical historic data
display connector J1 is shorted. The unit
displays the stored values within the set time
base as a graphical trend.
The time base can be set to days (7, 14),
hours (6, 12, 24, 48, 72) or minutes (3, 15,
30, 60).
The time base can be changed by
alternately opening and closing J1 (interval
< 2 sec). When first opening and closing J1
the current time base is displayed. For each
subsequent opening and closing the time
base changes to the next setting. In order to
save the setting permanently, the software
“Digalox Manager” has to be used.
J2 Min-Max display
To activate the Min-Max display connector
J2 is shorted. The display shows the
maximum and minimum values recorded
since the last reset. The values can be reset
by opening and closing connection J2
shortly (interval < 2 sec). The display shows
“Minmax reset”.
J3 Auto-scaling
To activate auto-scaling J3 connector is
shorted. The device automatically changes
the upper scale caption depending on the
current measuring value between 10, 100
and the set upper scale caption.

10. Maintenance
Periodically check all external cable connections.
11. Cleaning
Observe the safety instructions before cleaning the device. Clean the device with a
dry lint-free soft cloth. Do not use solvents.
