Operational faults

An operational fault is a failure in operation of either the display card or input module.
Operational faults are either
• critical – card may stop working, or
• advisory – card will continue to work safely, but its functions may be limited
When an operational fault occurs:
• Power LED flashes once a second
• If fault is critical, fault relay alternately energises and de-energises at 1Hz
• Display shows fault code alternately with normal display
In the situation where multiple faults occur consecutively, the first fault to occur will be
displayed. When that is cleared subsequent faults may be displayed if they are
unaffected by the clearing of prior faults.
In the situation where multiple faults occur simultaneously, only one will be indicated on
the display. The fault states are monitored continuously in the following order:
C, CM, BR, B , B , B, B , BS, BR, RR, D, E, I, L and H.
Any of these may be overridden by the hardware exception faults M and We.
Press R to clear the fault. If fault will not clear, or recurs, call DraegerService.
