Selecting the type of gas monitored for each sensor

The switch number 3 is used to select  reading the type of gas that the probe is connected to detect.
The LEL reading is obtained by shifting the switch to ON.

Explosive gas.

The ppm reading is obtained by shifting the switch to OFF

.

Toxic gas.

Positive  Safety-  Working  mode  of  the  relay  and  the  main  alarm

Switch  1  –  Selection  of  the  positive  safety
In  the  ON  position,  the  positive  safety  function  is  enabled.
The  relay  is  energized  after  performing  the  step  of  waiting  and  switches  when  the  BX150  is  main  alarm
In  the  OFF

 

position,  the  positive  safety  function  is  disabled.

The  relay  is  energized  only  when  the  BX150  goes  into  the  mainl  alarm

Switch  2  -  Working  mode  of  the  main  alarm  relay.
In  the  ON

 

(continuous)  position,  the  relay  remains  closed  until  the  N  button  is  pressed.

In  the    OFF

 

  (impulse)  position,  the  relay  remains  closed  for  20  seconds,  and  then  disenergizes  afterwards.
