3. Description

The measurement modes volt AC/DC, ampere AC/DC, frequency and 5 A current

transformer are supported Scale endpoint of the indicator as well as scaling of the

analogue signal and current transformer measurement can be adjusted freely via

the DIP switch, alternatively there is an option for automatic adaption of the scale

endpoint The unit can be switched between volt and ampere measurement via an

external switch Minimum and maximum values are recorded and can be displayed

optionally using an external switch Measured values are recorded over a time

span of 3 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, thresholds for alarm output, 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

Warning:

The device may only be operated in one of the connection options shown

above!

Current measurement on the high side (between plus and load) is

recommended only for voltages up to 50 V!

In this case the entire device is on high potential. Particularly to be considered

when connecting switches to J1-6.

5. Configuration

The device can be configured via DIP switches and jumpers manually or with the

corresponding software “Digalox Manager” via USB interface When configuring via

DIP switches and jumpers the basic settings can be made computer-independent

The configuration with the software “Digalox Manager” allows full functionality

caling

In modes where a scaling is necessary to represent the correct measurement value

(for example 5 A AC for current transformer) the upper scale value corresponds to

the primary value of the current transformer or shunt

Example:

upper scale value = 50 = primary value of the current transformer

Configuration via U B interface with software “Digalox Manager”

For configuration with software set DIP switch 10 to OFF position

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,

which is selected by the jumpers J4-J6 or the DIP switches 11-12

respectively!

(see table "Measurement mode").

Configuration via DIP switches and jumpers if only one measurement mode is

required (Manual mode)

1 Set DIP 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 DIP 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 ( ave mode)

The required measurement modes are configured and saved sequentially

1 Connect supply voltage

2 Set DIP-switch 10, 11 and 12 to OFF position

3 Set the measurement mode with jumpers at J4-J6 according to table

"Measurement mode”, column “Save mode"

4 Set DIP switch 10 to ON position

5 Set upper scale caption for the first measurement mode with DIP 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 DIP 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 2-8 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 DIP switches 1-9 Possible 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 DIP switches 1-9 to OFF position

3 Set DIP switch 10 to ON position

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 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, DIP switch 10

must be switched from ON to OFF position

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

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 IP65

protection (dust and water jet) when mounting in a front panel, use optional gasket

(separately available)
