Setting the Photocell
Washroom Mode
1.
If the lights are not already on, switch them on manually by pressing the
‘
up
’
button of the SENP (96004189).
Fluorescent lights do not reach full output until up to 15 minutes after being switched on, so ensure that the lights are
fully warmed up before continuing. This stage may be omitted if the intention is to operate the detector
’
s photocell
in Passive Mode only [the detector must have already been programmed to Passive Mode].
2.
Wait until the time of day when the natural light level is at the point below which you
want the lights to be on,
and above which you
want the lights to be on.
3.
Start the internal self-programming mechanism by pressing the
‘
Store
’
button of the SENP. The detector takes a
measurement, adds a small amount and stores the value in the Upper Threshold. Then it turns the lights off, makes
another measurement and stores the value in the Lower Threshold.
The lights now switch on again to
acknowledge a successful programming operation.
The two switching thresholds have now been set, and the difference between them is equal to the contribution made by
the electric lighting; this is the perfect amount of hysteresis to ensure that the lights will not oscillate. Please note that
the values are non-specific units i.e. not lx.
The unit may be used in conjunction with a 230V solenoid valve and a trickle valve or
‘
petcock
’
to effect a urinal flush
system. Set the water flow rate by adjusting the petcock so that the cistern
fills within the chosen Off Delay period of
the detector. Note that in this mode, the photocell should be disabled, unless using the dual output unit.
