Figure Number 16 - Setting the function of the external sensor
NOTE:
These inputs can be used, for example, to connect door sensor switches when we
want to distinguish which door sensor is open at a given moment and monitor this status
with the name of the sensor, which will be visible in the log, see figure no. 16 (Text). LES-
RACK can therefore have up to 4 door sensor switches that can be distinguished from each
other. If there is no need to differentiate the door sensors, you can connect the door sensor
switches in parallel. However, it is necessary to observe the same connection principle as
shown above and activate the Blocking function. (Alarms -> Select alarm: 6 Sensor1-3).

External temperature monitoring sensor
The installation is carried out in the protected space in which the temperature needs to be
monitored. The temperature sensor is used to check the temperature in the guarded area.
When the preset temperature limits are exceeded, the user-selected relay is switched on. The
length of the temperature monitoring cable (included in the product package) is 25 cm, at the
customer's request we can also deliver a cable with a length of up to 2 m or more.
After connection, the sensors must be activated via the web interface (Temperature ->
Thermometer -> Temperature2-3) Figure no. 17.
