1. Intended Use
Indoor use non condensing, non corrosive.
anel mounting.
Failure to comply with these instructions will void all guarantee and warranty.
In operation, supply the device preferably via screw terminals with 10 to 24 V
AC/DC. If the device is supplied via USB in operation, USB supply voltage must
be at least 5 V.
2. Safet instructions
Note: The measurement inputs of the device can carr life-threatening
voltages!
When working on the device hazardous voltages must not be connected to
the device!
The device must not be used as the onl protective device or protective
shutdown.
Read instruction manual carefully before operating the device!
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 250 V AC switches must be isolated for
at least 500 V.

3. Description
The multi display with RGB backlight is able to display up to 4 parameters
simultaneously. Thresholds can be associated with individual warning backlight
colours. The unit can be switched between measurement modes via an external
switch. Minimum and maximum values for each parameter are recorded and can be
displayed optionally using an external switch. Measured values of one parameter are
recorded over a time span of three minutes up to 14 days. The time base 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 software: 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 up to four measuring values can be enabled. Using the
software, values can be viewed and exported as CSV file.

5. Configuration
The device can be configured via DI switches and jumpers manually or with the
corresponding software “Digalox Manager” via USB interface. When configuring via
DI switches and jumpers the basic settings can be made computer-independent.
The configuration with the software “Digalox Manager” allows full functionality.
Scaling via DIP switches
When setting the scaling via DI switch to represent the correct measurement value
(e.g. 60 mV DC for shunt) the upper scale caption corresponds to the primary value
of the shunt.
Example:
upper scale value = 50 = primary value of the current transformer
Configuration via USB interface with software “Digalox Manager”
For configuration with software set DI switch 10 to OFF position.
lease note that the measurement mode selected in "Digalox Manager" is displayed
only until the power supply of the D M72 is interrupted.
In further operation, the device alwa s shows the measurement mode,
which is selected b the jumpers J4-J6 or the DIP switches 11-12
respectivel !
(see table "Measurement mode").
Configuration via DIP switches and jumpers if onl one measurement mode is
required (Manual mode)
1. Set DI switch 10 to ON position.
2. Set measurement mode with jumpers at J4-J6 according to table "Measurement
mode”, column “Manual mode".
3. Set upper scale caption for the first measurement mode with DI switches 1-9
(see “Configuration of the upper scale caption”).
4. Connect supply voltage.
----- 4 -----

Configuration via DIP switches and jumpers if it is required to switch between
multiple measurement modes via an external switch (Save mode)
The required measurement modes are configured and saved sequentially.
1. Set DI -switch 10, 11 and 12 to OFF position.
2. Connect supply voltage.
3. Set the measurement mode with jumpers at J4-J6 according to table
"Measurement mode”, column “Save mode".
4. Set DI switch 10 to ON position.
5. Set upper scale caption for the first measurement mode with DI switches 1-9
(see “Configuration of the upper scale caption”).
6. Set time base for graphical historic data display (optional, see “Other settings”).
7. Set DI switch 10 to OFF position.
8. "Saved” appears on the display. The configuration of the first measurement
mode is now completed.
9. When using multiple measurement modes repeat steps 3-8 until all required
measurement modes are configured. The time base does not need to be set
again, as it is used for all measurement modes.
10. In operation the measurement modes can be changed with a switch at J4-J6
according to table "Measurement mode”, column “Save mode".
Configuration of the upper scale caption
The upper scale caption is binary coded using DI switches 1-9. ossible values are
1 to 500. Switch 1 corresponds to 256, switch 2 corresponds to 128, switch 3
corresponds to 64, etc., switch 9 corresponds to 1. For configuration, proceed as
follows:
1. Connect supply voltage.
2. Set DI switches 1-9 to OFF position.
3. Set DI switch 10 to ON osition.
4. Start with 1st switch.
5. Set switch to ON position.
6. If the displayed value is greater than the desired value, set the switch back to
OFF position.
7. If the displayed value is less than the desired value, leave the switch in ON
position and move on to the next switch.
8. Repeat steps 5 to 7 until the desired value is displayed.

6. Other settings
The following functions can be activated independently by short-circuiting
connectors J1-J3 by jumper or switch during operation:
J1: Graphical historic data displa
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, DI
switch 10 must be switched from ON to
OFF position.
J2: Min-Max-displa
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.

7. Mounting
Carefully insert the instrument into the panel cut-out. Insert the mounting bracket
from the back and push towards the panel until the instrument sits tight. Make sure
the mounting bracket is snapped into the side of the housing. To ensure I 65
protection (dust and water jet) when mounting in a front panel, use optional gasket
(separately available).
