Off Delay
The Off Delay may be set between 5 and 35 minutes (SLOCSP only). 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)
The SCLOCSP 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)
Not applicable.
Defaults
(where applicable)
The units are supplied with factory default settings (Power-Up On, fully Automatic operation, a 20 minute Off
Delay, no 24hr Cycle, Passive Photocell). Programme using the SENSALINK SENLP Programmer with LCD
display, or the SENSA SENP Programmer incorporating 12 dil switches.
Please note that additional
parameters are available
