Set Flush Timing
Power connection (from power supply)
Flush time selection (Seconds)
Test mode:
The rotary switch on the board is marked 0 to 9
Position 0 is test mode, where the system will operate automatically for a number of cycles.
Operational mode:
Positions 1 to 9 are flush times in seconds (i.e. Valve opening times).
When first powered the sensor will wait 2.5 minutes and then calibrate it’s surroundings,
after this period it will be ready to detect.
Setting Flush Time:
The beam from the sensor is very narrow so care should be taken when installing so that it
is mounted above the urinal where the user would be.
The sensor will only accept someone as a user if they stand under the beam for 5 seconds
or more, when the user walks away there is a 3 second delay and it will flush for the time
you have set on the rotary switch.
The unit can only be used with the supplied power pack.
Mount the sensor away from lights, hot pipes, ceiling transformers and direct sunlight.
Do not touch components on the board with your fingers.
If the water pressure is greater than 700 kPa then a 350 kPa pressure reducing valve must
be fitted upstream of the latching valve.
Adjust the timing of the flush to ensure an adequate flush, by setting the flush switches on
the sensor board (see diags. below)
When setting the fill time ensure the water does not backup the connection pipe and spill
out of the Air break. If the water is overflowing, or close to overflowing, reduce the fill time,
or pressure. Alternatively, fit a 6 l/m flow restrictor.
Recommended flush settings:
The recommended setting for a single urinal is No.2, when supplied with 350 kPa water
pressure. (see notes on page 11)
NOTE:
Units supplied with
a YELLOW rotary
switch, will not have
a test mode.
For these units
Position 0 will be
non functional
