Steps for setting the current protection:
1. Login to the web server and go to page for the Main Controlled Device
.
2. Click the "
Close
" button so the door (barrier, window, tent) will start
CLOSING
;
3. The "
Real Time Current Sensor Value
" will start updating;
4. After the door (barrier, window, tent) is closed the "
Max Current Read Value
" will be
updated with the maximum measured value.
5. Set the "
Current Protection Limit
" with higher value than the "
Max Current Read Value
".
The "
Current Protection Limit
" must be higher than "
Max Current Read Value
" so that
there will not be fake detections but it must be also as low as possible so that over-
currents will be detected easily
Use "
Current Protection Limit"
feature only if possible and with HIGH ATTENTION as
per the Main Controlled Device manufacturer. It may damage your stuff if not proper
tuned.
smartDEN Opener
can control motor with maximum consumption 4A or that is about
300 ADC raw units which means when the "
CLOSE
" button is clicked, the "
Real Time
Current Sensor Value"
and "
Max Current Sensor Value
" must be less than 300.
This type of protection is not suitable for all types of applications. Please use it with care!
Set up the parameters only as per the Main Controlled Device manufacturer.

Setting the secondary protection via digital input
smartDEN Opener
provides additional protection using digital input. In this way it is suitable to
use for example barrier detector with SPST output showing when there is human or car under the
barrier (door). One digital input could be attached as a DI protection sensor.
Figure 6.38.
DI protection sensor options (Main Controlled Device page)
When this protection type is used the Main Controlled Device may be closed automatically
(auto-close) if DI protection sensor is deactivated depending on the settings. When attaching DI
protections, the activated level must be selected as well. For example if high level is selected for
activation then low level will deactivate the DI protection sensor:
Never
- selected digital input does not make
CLOSE
automatically;
On Close Command
- CLOSE automatically on deactivated DI protection sensor if only
there is a
CLOSE
command. If DI protection sensor is in activated level then
CLOSING
operation is delayed until deactivation level occurs (i.e. car is not under the barrier anymore
for example);
Always
-
CLOSE
every time when DI protection sensor is deactivated;
