Off Delay
The Off Delay may be set between 5 and 35 minutes. A 10-second Off Delay is available for walk-testing the
product. In a typical office environment a 20-minute Off Delay is usually satisfactory.
Movement Detector Operation (Automatic / Semi-Automatic)
Where absence detection is required (ie the user manually turns lights ON if required but lights still turn off
automatically once an area is vacated), semi-automatic operation can be set via the programmer.
Power Up Setting (On/Off)
Set to ON the detector will automatically switch its outputs on when Mains is applied. If set to OFF, the detector will
power up without turning its outputs on, wait for 30 seconds and THEN look for movement. Only if the area is
occupied will the output switch on at this time. The detector must be set to Power Up ON when used in conjunction
with semi-automatic operation.
Photocell Operation (Passive/Active/Disabled)
This detector has an in-built photocell. The photocell has three modes of operation - Passive, Active and Disabled.
Its operational behaviour is governed by the setting chosen and by the values stored in the Upper and Lower
thresholds (see diagram overleaf).
Passive
- The photocell will inhibit turn-on of the controlled load if sufficient natural light is available. It will not turn
the load off whilst an area is occupied
Active
- The photocell will turn the controlled load on and off as required whilst natural light levels fluctuate during a
period of occupancy. This mode of operation operates in conjunction with a passing cloud timer (PCT). The PCT is
asymmetrical in operation - the load will be switched on immediately that the light level falls below the lower set
point, however, the load switches off only if the light level exceeds the upper threshold
continuously
for a period
equal to the Off Delay.
Disabled
- The photocell has no effect.
24hr Cycle (Yes/No)
For use in ‘Washroom Mode’ only (see overleaf). In this mode it is necessary to have a hygiene cycle (flush) if the
area has been unoccupied for 24hrs. Select this feature and the output will switch on for the duration of the Off
Delay once every 24hrs if the area remains unoccupied.
Commissioning
The units are supplied with factory default settings (Power-Up On, fully Automatic operation, a 20 minute Off Delay,
no 24hr Cycle, Photocell Disabled). Programme using an infrared programming tool. Please note that the full
range of parameters is accessible via the HP2000; the HP10 and HP18 offer different/limited programming options.
Walk-test Mode
Walk-test mode is used to check that the detector is operating as required. The short off-delay enables the installer
to check that lights are switching on when movements are made at the edge of the detection zone. It is easier to
carry out a walk-test when the photocell is not holding the lights off.
1. Change the Off Delay to 10 seconds using the HP10 or press ‘TEST’ (HP18) or ‘Utilities/Walk Test/OK’ (HP2000).
2. Move around the area that is being controlled, stopping for 10 seconds to allow the lights to switch off, before
moving and triggering the lights back on. Re-programme the desired Off Delay once testing is complete. Note: If
the HP2000 or HP18 was used to engage ‘soft’ walk test mode as described above, the programmed Off Delay
will be automatically restored after 5 minutes.
