3. Remain still. The red and green LEDs should not flash. The lights should turn OFF after 5 seconds. (If not, see Troubleshooting.)

4. Move about the coverage area. The lights should come ON. Adjust the Ultrasonic Sensitivity as necessary to provide the desired

coverage (Green LED indicates activation from the ultrasonic sensor).

When testing and adjustment is complete, reset DIP Switches to the desired settings, and replace the cover on the sensor.

* Test Mode is a temporary state that starts when you first set the sensor's DIP switches for the "Test Mode/20 minutes" (switches 1, 2,

3 OFF). If you need to invoke the Test Mode and the DIP Switches are already set for Test Mode/20 minutes, toggle DIP Switch 1 ON

then back to the OFF position. This provides a 10 minute test period. During the test period, the Time Delay is only 5 seconds.

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-205 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-205 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.

The Manual ON function is facilitated by installing a momentary switch such as Wattstopper 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.
