PRODUCT DESCRIPTION
DOL 61 Display and Alarm Unit can be used
with all sensors with 24VDC supply voltage and
0-10VDC or 0-20mADC outputs. DOL 61
features a relay, that can be programmed to
activate when a specific input criterion is met.
The relays can for example be used to sound
a horn or flash a lamp when the ammonia level
in a house exceeds 50ppm.
DOL 61 is capable of powering a sensor with
24VDC.

1: Status – measurement
2: Current measurement
3: Channel (analogue input) 1-1
4: History
5: Configurations
6: Current date/year
7: Current time
2. FRONT MENU
The front view displays the measured values from the sensor.
When Threshold 1 is exceeded, the status changes from green to orange .
When Threshold 2 is exceeded, the status is shown as red .
DOL 61 supports one channel.
There is also access to the history view and the configuration menu .
The current date and time is also shown.
3. HISTORY
The history view shows the measured values during the current week. Switch between
weeks by means of the arrows , .
4. CONFIGURATIONS
In the configurations menu, all settings can be made. Tap a field to be able to make settings.
Settings are stored by means of the save button .

4.1 CONFIGURATIONS – NUMBER OF CHANNELS
DOL 61 supports one channel/one sensor.
Settings are stored with the save button .
To return to the configuration menu, tap the close button .If you do not save the settings before
returning to the configurations menu, the settings are deleted.
4.2 CONFIGURATIONS – SETTING CHANNEL
Make settings for the channel/sensor. Tap the pencil to rename it.
Select the unit of measure (Unit), the upper and lower limit for the sensor measurement range
(Scaling) as well as the thresholds.
If the input is changed from 0-10VDC to 0-20mA, the scaling for 0mA must be set at “Scaling 0V”
and 20mA at “Scaling 10V”.
When Threshold 1 is exceeded, the status changes from green to orange .
When Threshold 2 is exceeded, the status is shown as red .
Both Thresholds are set according to the scaling for the input.
RELAY
When threshold 2 is exceeded, the relay changes.
Value on channel 1 below threshold 2, shorted relay.
Value on channel 1 above threshold 2, open relay.
No power connected to DOL 61, open relay.
4.3 CONFIGURATIONS – LANGUAGE
Here you can select the displayed language.
4.4 CONFIGURATIONS – SYSTEM DATE
Here you can set the date and time (DD/MM/YYYY).
4.5 CONFIGURATIONS – SYSTEM TIME
Here you can set the system time (hh/mm).
4.6 CONFIGURATIONS – DATA ON USB
In this menu, the measured values which are saved on the Mini SD card can be copied to a
USB stick. This is done to avoid losing data, when the Mini SD card is removed.
4.7 CONFIGURATIONS – RESTART
Tapping Restart resets the unit to default.TECHNICAL USER GUIDE

4.8 CONFIGURATIONS – UPDATE SOFTWARE
In this menu, the software can be updated from a USB stick.
The files must be stored on a stick in a folder named “bin” (Stick:/bin/).
The update function lists the firmware-files (.bin) when starting it.
If more than five files are stored, you can navigate between them using the arrow buttons. Pushing
the up button while placed at the top of the list, scans the folder again.
If no stick is detected, the stick must be removed and connected again, push the up button to re-
scan the folder.
When a file is selected, it can be installed by pushing the button .
The text „Install…“ shows that the installation is active. The selection is displayed again after a
successful installation.
Push the play button to make the application start.
4.9 CONFIGURATIONS – DECIMAL SEPARATOR
Here the decimal separator can be set for the data logged on the SD-card/USB stick, the
decimal separator on the screen is always a dot.
4.10 CONFIGURATIONS – ABOUT
Here the current unit version is displayed.
