Setting DIP Switches for Cable Length
The hazardous area control unit has a display barrier (BAREX4120) which the display is connected to.
This has a PCB with three DIP switches to match various display cable lengths to the display barrier.
After trimming the display cable to required length these DIP switches must be set as follows:
o
If the cable length is up to 2.5 metres in length then the 2.5 meter switch (SW3) is set to “ON”
and switches SW1 and SW2 are set to “OFF”.
o
If the cable length is greater than 2.5 metres up to 5 metres in length then the 5 meter switch
(SW2) is set to “ON” and switches SW1 and SW3 are set to “OFF”.
o
If the cable length is greater than 5 metres up to 10 metres in length then the 10 meter switch
(SW1) is set to “ON” and switches SW2 and SW3 are set to “OFF”.
