– All the LED segments are activated for approx. 5 seconds directly
after switching power on to make sure that the display is
functioning correctly ("lamp test"). During this period, internal test
routines are run in the remote access box.
– "RAB" will then flash on the display for a period of approx.
60 seconds. During this time, it is not possible to access all
the menus.
– After approx. 65 seconds, the remote access box is ready for
operation and changes to standby mode (see page 28).
 Change into operation for maintenance (see page 29) to check
the communication between remote access box and gas
transmitter.
 Reassemble the housing cover of the remote access box –
ensuring that it is free of dust – and refasten the cover screws.
CAUTION
There is no dust explosion protection after opening the cover of the
energised remote access box. The hazardous area has to be
temporary de-classified if necessary.
