Launch of the controller 

After turning on the power supply, the whole LCD Display lights up and loads the highest meassured concentration, which 
remains on the display for cca 3s. After that the controller goes into preheating mode. The main LCD displays a countdown to 
the end of preheating and the secondary segments display the inscription „HEATING“.

Basic status/alarms 

The controller displays the concentration on 4 main segments. To it's right, units and the detected gas are being displayed. The 

8 auxiliary segments display the location or an evnetual sensor malfunction. If the displayed channel is digital 

 (1 to 

32), the adress 

 of the connected sensor is also displayed. Connected analog transmitters 

 have a range 

of 41 to 48. The controller sequentially switches the configured channels in a 3s interval.  If we want to select a transmitter 
manually, we can do so with the buttons LEFT and RIGHT. 
The status of the sensor bundled with an output relais (alarms, time-weigted avarages, statuses of temperature sensors and 
floodings, malfunctions) is displayed in the right part of the LCD.  
In case of an increased concentration, the LED ALARM starts shining and the controller switches to the channel, which 
meansured this concentration. After 30s the channels will again be sequentially switched. 

The latch function

 – catalytic and semiconducter sensors can, when exceeding the measuring range, indicate a lower 

measured value than it really is. If the measured concentration of these sensors exceed 100% of the lower explosion level, the 
latch will activate. Even after a drop of the measured concentration, the transmitter will still be in it's highest alarm level. The 
detection area must be physically checked by an independent transmitter and after that the controller can be unblocked by 
pressing the ENTER button. 
The ENTER button also serves as a confirmation button for the acoustic alarm.
