On the board you will notice three in-line switches fitted to the
right side of the DIP switches (Fig. 4). Only switch A is used.
Option switch A (when switched ON) provides two functions, a
pre-flush and a purge option.
The pre-flush opens the valve for 1 second after the first 2
seconds of detection. This helps to prevent splashing by wetting
the urinal bowl. After the pre-flush the timing continues.
The purge is initiated every 12 hours of non-use on either channel.
This helps reduce smells from the urinal during periods of non-
use.
Settings:
Switch A ON = Pre-flush plus purge
Whilst the unit is still powered down the time settings can be
setup.
The numbers printed on the switches (1, 2, 3, 4) simply identify
the switch number; the actual time settings available are shown
below:
Switch 1 ON = 1 seconds
Switch 2 ON = 2 seconds
Switch 3 ON = 4 seconds
Switch 4 ON = 8 seconds
Example above (Fig 5) shows switch 2 and 3 ON. This gives a total
flush-time of 6 seconds
Testing the sensors
A test routine is included for verifying the operation of the
sensors.
After installation of external equipment, the supply should be
connected.

To put the unit into test mode set DIP switches 1-4 to the OFF
position.
When power is applied LED’s 2 and 3 (Fig 2) will switch on
corresponding to an object within range. For example, if sensor
1 (left hand channel) detects and object in range then LED 3 (left
hand LED) will be on as long as the sensor detects the object.
Sensor 2 operates LED 2 as above. This routine helps to identify if
the sensors are detecting unwanted objects.
Operation:
When a person comes into range of a sensor a counter starts
and after 10 seconds it is determined that the person is an actual
user.
When the person leaves the sensing range the corresponding
valve is opened for the set flush-time. However, a 2 second delay
is built into the counter to allow the person to leave the range
and return after or before the 10 seconds without effect on
the counter. This also means that the valve will not open for 2
seconds after the user has left the area.
Each of the two channels operates independently, but both use
the same settings.

IMPORTANT :
Changes to settings can only take place when
power has been disconnected for at least 5 seconds.
