Setting up the SPC-E
Once power has been applied
(24VDC) the Beam Detector can now
be aligned. The covers on both the
Emitter and Receiver need to be
open. The green polling LED on the
Receiver should now be flashing once
per 3 seconds, but please note the
units require between 30 and 60
seconds to fully power-up.
On the top right of the Receiver there
is a sight hole, when looking through
this the Emitter should be clearly
visible in the centre of this hole
(please refer to Fig.4.). If it isn’t, then
using the silver alignment wheels (left
wheel horizontal adjustment, right
wheel vertical adjustment) the
Receiver should be adjusted until the
Emitter is clearly visible.
Fig.4
This procedure should then be repeated at the Emitter end. Set the distance switch on the emitter according to the
monitoring distance and close the cover of the emitter. Close the cover, then fasten the locking screw, refer to Fig.5.
Once this has been achieved
the 4-part DIP switch needs to
be set. Bits 1 and 2 are set
according to which signal
strength is required; there are
three choices available, 25%,
50% and 60%.
Bit 3 can be set to switch the
signals to be emitted when the
beam is blocked to fault and
fire(OFF), or to fault alone(ON).
Bit 4 can be set to switch
between the automatic(OFF) or
manual(ON) recovery from the
fault status.
Please note that if
the SPC-ET is set to show a
non-latching fault on total
obscuration, and the SPC-ET
beam is blocked for more than
30 minutes then the fault will
LATCH. To remove this fault
the SPC-ET will need to be
powered down, or the receiver
cover will need to be opened
and then closed to re-
synchronise the receiver with
the emitter.
The cover on the Receiver can
now be closed (please refer to
Fig.5.), this should be done
carefully, avoiding the possibility
of moving the SPC-E out of
alignment.
Fig.5
Closing the cover on the receiver synchronizes the receiver with the emitter, then automatically adjusts the
amplification factor of the reception circuit, then initiates fire monitoring.
