A. Manually Changing Sensor Range
1.
Turn power to sensor OFF. Wait 60 secs, turn power back ON.
2.
Red light in the sensor flashes quickly for 5 secs (approx 2 flashes per sec).
3.
While the light is flashing, move a hand close to sensor (30 to 50mm).
4.
When the light stops flashing, it goes to solid red (stays ON). Take hand away from the sensor.
5.
Stand in front of the urinal at the required distance (range 400 to 800mm).
6.
Wait 5 seconds until sensor light starts to flash again. (Range is now set).
Manually changing run time (with run times restricted)
If required to change run time, carry out steps 1 to 6, then
7.
IMMEDIATELY move hand very close to the sensor.
8.
After 5 secs., the fast flashing red light in the sensor will flash slowly (1 flash every 2 secs.).
9.
Count slow flashes; take hand away from sensing region after required number of flashes:
i.e.:
By taking hand away after 3 slow flashes, the run time will have been set to 3.5 seconds

(SENSOR SHOULD NOT BE LOCATED DIRECTLY OPPOSITE A WALL MIRROR.)
The sensing range & run time can both be adjusted.
Default factory settings
are 400mm range & 4 seconds run time.
Run time of 4 to 10 secs is considered satisfactory for most applications. Too short a run
time will reduce the frequency at which an auto cistern flushes. A long run time can
increase water consumption.
This can be done in one of two ways: (A) manually or by (B) using a remote sensor programming unit
with some manual actions.

SENSOR RANGING & RUN TIME ADJUSTMENT
DURING SETTING UP PROCEDURE AVOID WEARING HIGH
VISIBILITY CLOTHING IN FRONT OF THE SENSOR
For example, with a run time set at 6.5 seconds, this would give 0.65 litres of water discharged into an
auto cistern for each usage of the urinal (sensor activation).
Therefore, based on a auto cistern of 4.5 litre capacity, the urinal would have to be used 7 times before
the siphon is triggered to flush.
General fill rates & capacities
The flush volumes shown in the table above are based on 6L/min (0.1L/second).
