9.3 Fault indication
[OL]
overload pressure (measuring range exceeded)
[UL]
underpressure range (measuring range below the minimum value)
[SC1]
short circuit in OUT1*
[SC2]
short circuit in OUT2*
[SC]
short circuit in both switching outputs*
[Err]
internal fault
•
nominal pressure (final value of the measuring range) exceeded by 5
•
times�
*The output concerned is switched off as long as the short circuit continues�
The faults SC1, SC2, SC, Err are indicated even if the display is deactivated.
