4.9 Manual switching

—on in case of sufficient ambient light / forced

shutdown (switch off)

In full automatic mode, the detector automatically switches on as soon as it detects
movement and ambient light is too low. If switch-on is also permitted via an external switch
at high ambient light levels (above the selected threshold), this must be enabled through a
parameter (Manual switching-on in case of sufficient ambient light).

In semi-automatic mode, the detector must essentially be switched on manually. Here, a
parameter defines whether the detector can be switched on only at a brightness level below
the selected brightness threshold, or also above it.

If the detector is switched on manually at a high ambient light level (above the selected
threshold), its behaviour depends on the selected mode:

• In switching mode, the detector switches on the lighting and remains active as long
as  there  are  people  in  the  room.  After  the  follow-up  time  has  expired,  the  lighting
switches off (re-triggered by each new movement). If forced shutdown is active,  the
lighting  is  switched  off  after  15  minutes  if  the  ambient  light  is  continuously  bright
enough.
• In regulating mode, the detector switches on the lighting at 10% for the duration of
the follow-up time (re-triggered by each new movement) or for forced shutdown (switch
off), for 15 minutes, as long as brightness remains above the set value. As soon as the
light level falls below the set value when the lighting is active, lighting regulation is used
(starting from 10%).

Manual switching-on when ambient light is sufficient reduces the potential for saving energy.
With forced shutdown (switch

off), the manually “forced” switch-on period can be limited to

15  minutes.  This  parameter  is  visible  once  the  “Manual  switch-on  in  case  of  sufficient
ambient  light”  parameter  is  activated.  Forced  shutdown  (switch  off)  is  active  if  a  manual
switch-on takes place at sufficient ambient light levels. If it continues to be bright enough for
15  minutes,  the  regulating/switching  channel  is  switched  off.  In  regulating  mode,  if
brightness falls below the set value, normal regulation is used.
