MANUAL ON FUNCTION
The
Manual ON
function is facilitated by installing a momentary switch such as Wattsopper LVSW Momentary Toggle Switch. The
switch connects to the sensor’s Manual (Man.) Switch and +24VDC terminals as shown in the wiring diagram. Each time the switch is
pressed, the load changes state. The sensor’s operation as related to the manually operated switch is determined by DIP switch settings
for Occupancy Logic.
Manual Mode
(Trigger Option 6 or 7): In this mode, the switch
is required
to turn
ON
the load. The sensor keeps the load
ON
, based
on occupant activity. After the time delay ends, if there is no movement detected within the 30 second re-trigger period, the load turns
OFF
and the manual switch must be used to turn
ON
the load.
Automatic Mode
(any Trigger Option except 6 or 7): These options use occupancy triggers as well as switch activation to turn the load
ON
. A manual switch provides the following additional functionality:
• The load can be turned
ON
using the manual switch and it stays on according to the occupancy logic setting. The time delay
operates as programmed. When the load turns
OFF
due to lack of occupancy detection, it can be turned
ON
again by occupancy
detection or the switch.
• Activating the manual switch while the load is
ON
turns the load
OFF
.
▸
When the load is turned
OFF
manually, as long as the sensor continues to detect occupancy the load stays
OFF
. The length of
the time delay after the last occupancy detection, the lights stay off and the sensor reverts to the automatic-on mode.
▸
When the load is turned
OFF
manually, pressing the switch again turns the load
ON
and the sensor reverts to the automatic-on
mode.
▸
Once returning to automatic-on mode, either the switch or occupancy detection can turn the load
ON
.
DIP SWITCH SETTING
Time Delay: Switches 1, 2, 3
The sensor will hold the lights
ON
as long as occupancy is detected. The time delay countdown starts
when no motion is detected. After no motion is detected for the length of the time delay, the sensor will
turn the lights
OFF
.
Walk-through: Switch 4
Walk-through mode turns the lights
OFF
three minutes after the area is initially occupied, if no motion is
detected after the first 30 seconds. If motion continues beyond the first 30 seconds, the selected time
delay applies.
PIR Sensitivity: Switch 5
• Minimum forces a reduced detection range for the PIR.
• Maximum causes the DT-200 to monitor the controlled environment and automatically select the
maximum sensitivity that will provide reliable operation without false detection. This setting is
constantly updated.
Occupancy Logic: Switches: 6, 7, 8
The DT-200 has 8 logic configurations for occupancy triggers, set with DIP Switches 6, 7 & 8. Determine
the appropriate Occupancy Logic Option using the Trigger matrix, then set the DIP switches accordingly.
Initial Occupancy:
The method that activates a change from “Standby” (area unoccupied and loads are
OFF
) to “Occupied” (area occupied and loads are
ON
).
• Both requires detection by PIR and Ultrasonic.
• Either requires detection by only one technology.
• PIR requires detection by the PIR.
• Man. requires activation of the Manual Switch. (See
Manual ON
functions for further information.)
Maintain Occupancy:
The method indicating that the area is still occupied and the lights should remain
ON
.
Re-trigger:
After the time delay elapses and the lights turn
OFF
, detection by the selected technology
within the number of seconds indicated turns the lights back
ON
.
OVERLOAD PROTECTION
The occupancy sensor has a built in overload protection function that will automatically turn
OFF
the control output when the load
current exceeds 200mA. The sensor LEDs will then blink rapidly (~ 10Hz) to provide a visual indication of an overload condition. When
the load current is corrected or returns to normal, the control output will turn back
ON
