Overload Protection - LEGRAND Wattstopper Manual De Instrucciones

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-305 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-305 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 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.
For any unexpected operation:
1. Check DIP switch settings. Make sure the switches are set according to the defined settings in the DIP Switch Setting chart.
Lights do not turn on when entering the room.
Neither LED Flashes.
1. Check that the circuit breaker has been turned back on.
2. Check all sensor and power pack wire connections.
3. Check for 24VDC input to the sensor between the red and black low voltage wires.
• If 24VDC is present, replace the sensor.
• If 24VDC is not present, check the high voltage connections to the power pack.
• If high voltage connections are good and high voltage is present, replace the power pack.
Red LED does not flash.
1. When power is initially applied to the sensor, there is a warm-up period of 30 to 60 seconds before the LED becomes active.
2. Make sure PIR sensitivity is set to 100% (DIP switch #5 is in the "off" position).
