Green flashing light on / off
. By using the
right
and
left
keys you can turn the green
flashing LED, located on the head and controller,
on
or
off
. This is a useful way of
identifying the beam head you are working with (press
enter
to return to
mode
change
or
down
to go to
phase
).
Phase
. When using multiple beams that face each other the beam output signals could
phase together and can cause unreliable readings, by setting each beam to phase
differently alleviates this problem. Use the
right
and
left
keys to give each beam a
different phase pattern (length between output beam sample times) you can choose
between
0 (default setting)
and
6
(press
enter
to return to
mode change
or
down
to
go to
hysteresis
).
Hysteresis
. Changing the
hysteresis
will change the delay in returning from a
fire
state
back to a
normal
state, for example, the beam is factory set at 15% so if the beam
falls into fire at 65% (35% threshold) it has to recover 15% to 80% before it returns
to normal. This action prevents small fluctuations in returned signal causing the
beam to fall in and out of a fire state. This can be adjusted between
1%
and
40%
by
using the
right
and
left
keys (press
enter
to return to
mode change
or
down
to go to
compensation fire / fault
).
4. Press
enter
to go into
beam maintenance
.
Dirt Comp
. This screen shows how much the beam has compensated for dust build-
up on the beam head and reflectors,
ALWAYS
take a note of this value as part of your
routine maintenance to see any build-up pattern, if you see figures above
+50%
you
should clean both the lens face and the reflectors (once cleaned you should instigate
an
auto alignment
to re-calibrate the beams settings).
It is possible that you may see a negative number here, this can happen when the
ZetaBeam has been commissioned in a ‘dirty’ atmosphere such as builders dust which,
once cleared, the beam then compensates for. To reset, perform an
auto alignment
to
re-calibrate the beam (press
enter
to return to
beam maintenance
or
down
to go to
event counts
).
