Night Activated Switch w/ Timer

1 - 12 Hour Timer
Power Supply 12 VDC
Consumption: 50 mA Max
Uses one switch to control all operations and settings
6 LEDs 3mm, indicates timer settings
Delay on: 5 seconds
Delay off when photo transistor detects light: 5 seconds
500 Watts max load
Dimensions: 70mm x 55mm or 2.76 x 2.15 inchs"

CONNECTING AND TUNING
- "12V" and "G" point is used for connecting the 12VDC power supply available at a 2 pole screw terminal connector
- Switch SW are used for setting the timer, start and stop.
- NO, COM, NC contacts are available at a 3 pole screw terminal connector

- Trim pot for adjusting the sensitivity of the photo transistor.

OPERATION
1. When 12VDC is applied to the circuit, LEDs will each light indicating the delay time.
2. When the photo transistor has no light to detect, the circuit will start timing. LED or LEDs will begin to blink, in 5 seconds the relay will turn on. If you push the switch within 5 seconds the relay will come on immediately. If you wait after 5 seconds of darkness the relay will energize. The relay LED comes on and the setting display LEDs will flash.
3. When the circuit has completed counting the 5 second delay, the LED will turn on or stop flashing and the relay will turn off.
4. If the photo transistor detects light the circuit will stop. The light will have to be steady and last at least 5 seconds or it will have no effect.
