MS4800FS system.
4-3-2 MS4800FS Segment Reduction Restart Procedure
!WARNING
Do not remove cascaded segments from your installation without making sure
that the accessible areas are protected by other measures. Failure to do so
may result in serious injury.
When you reduce the number of cascaded segments you cause a flex bus
fault. The MS4800FS will enter a fault condition, indicated by error code "95"
on the indicators in the bottom part of the device. This fault code indicates that
there was a reduction in the number of cascaded segments. If the number of
segments is reduced while power is off, the light curtain will power on with
fault code "100".
There is one possibility to clear this fault and restore operation on the reduced
size MS4800FS. The start switch needs to be pressed while the power is
applied. The three indicator LEDs (red, yellow, amber) will flash for approxi-
mately three seconds. The start switch must be released while the LEDs are
flashing to clear fault code "100". Since the MS4800FS has a configurable
start input, care must be taken to ensure that the correct contact configuration
is used and that it is wired properly.
The transmitter will not fault if the number of segments is reduced. However,
to operate normally the transmitter must always match the receiver in the
number of segments and beams.
