SAFETY INSTRUCTIONS

Important safety information to reduce risk of fire injury.

1. Do not install within 10 feet (3 m) of a pool, spa or fountain.
2. There are no serviceable parts inside the power supply unit. DO NOT DISASSEMBLE.
3. Do not repair or tamper with cord or plug.
4. Do not submerge transformer in water.
5. Do not mount the transformer onto combustible material.
6. Do not connect two or more transformers in parallel.
7. Do not use the transformer with a dimmer switch.
8. Plug the power supply unit directly into a GFCI wet location outlet.
9. For use with low voltage outdoor landscape lighting system only.
10. The maximum output of this transformer is 100 watts. Do not overload the transformer. Be sure that the total cumulative wattage of all 12 volt fixtures connected to the transformer is equal to or less than 100 watts.

CAUTION: This landscape light system must be installed in accordance with all local codes and ordinances. If you are experiencing problems, contact a qualified electrician.

CALCULATION LIGHTING CAPACITY

The 100 Watt transformer has 100 watt circuits which will power up to 100 watts of light. To make sure the maximum number of fixtures can be safely connected to this transformer, add up the individual wattages of  all the fixtures. The total wattage of your fixtures must not exceed output capacity of the 100 Watt transformer.

INSTALLATION

1. Preparing the Cable
   Being careful when splitting it. NOT to expose the copper cable. Remove the landscape cable insulation 1/2 inch from both cables and twist ends.

2. Connecting the cable to the Transformer
   Lay the transformer on a flat, stable surface and use screwdriver to connect the stripped ends of the cable under the terminal clamping plate.

3. Placing Your Fixtures and Routing the cable
   Lay your fixtures (not included) to your desired location. Be sure they do not exceed the 100-watt rating of the transformer. Coil the rest of the cable after the last fixture.

4. Attaching Your Fixtures
   Use the cable connectors to attach your fixtures with the cable. Plug the transformer in the GFCI outlet and enter the ON mode. Then the lamps will light up.

5. Mounting the Transformer
   Use the screw to mount the transformer directly on a wall. 12 inch to 48 inch (0.3 m to 1.2 m) high from the ground would be suggested. Mount the photo eye bracket on a wall with the screw provided. Snap the  sensor into the bracket. Route or coil the excess wire to protect it from lawn mowers, trimmers, etc.

OPERATING INSTRUCTION

Figure 1: OFF MODE
The transformer does not work, there is no output voltage, and the load lamps will not light.
Figure 2: ON MODE
The transformer will maintain the output throughout the day, and the load lamps will always be on.
Figure 3: AUTO MODE
In this mode, it will take O ~30s for the transformer to detect the external environment firstly. If it is night, the currently selected output port of the transformer will start output later, then the load lamps will light on automatically and off at dawn. If it is during the day, the currently selected output port of the transformer will have no output and the load lamps will not light.
Note:
If the light emitted by the load lamps shines on the sensor at night, it may cause the transformer to continuously switch on/off, and the load lamps flash continuously, with a flash interval of 30s.
Figure 4 & Figure 5: COUNTDOWN MODE
In this mode, it will also take 0~30s for the transformer to detect the external environment firstly. If it is night, the currently selected output port of the transformer will start output later and the load lamps will light. Then they will turn off automatically when the the countdown is over. If it is during the day, the currently selected output port of the transformer will have no output and the load lamps will not light.
Note: When the system starts to count down, if the surrounding light shines on the sensor for more than 30s, the countdown will end, the currently selected output port of the transformer will stop output, and the  load lamps will go out.
: Selecting the function On-Auto-Countdown-Off.
TIPS:

1. When the transformer is working, the dot in the lower right corner of the display lights up. If the dot is not light up, it means that the transformer has no output voltage.
2. The transformer has a power-off memory function. When the transformer powers on again, the transformer will enter the working mode before the power failure.

TROUBLE SHOOTING

T1. The display shows “F”
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer is overloaded or not.
Step 3: Check if there is a short circuit at the transformer terminals.
Step 4: Check whether the connection between the lamp and the buried wire is short-circuited.
Step 5: Press the circuit breaker button switch.
Step 6: After troubleshooting, relog the transformer, it will automatically reset.
T2. In ON mode, the load lamp is off, the display shows “O”
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer terminals are properly connected.
Step 3: Check whether the connection between the lamp and the buried wire is correct.
Step 4: After troubleshooting, relog the transformer, it will automatically reset.
T3. In AUTO mode or COUNTDOWN mode, the load lamp does not light, the display shows “A” or “N” (N is the selected timing time).
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer terminals are properly connected.
Step 3: Check whether the connection between the lamp and the buried wire is correct.
Step 4: After troubleshooting, replug the transformer into the power outlet.
Step 5: Press the up/down button to enter AUTO mode or COUNTDOWN mode, cover the sensor for more than 30s, the load lamp will light up.

CABLE SELECTION CHART

AWG¹ Not recommended for Halogen Landscape.

NOTE: This data is provided as a general guideline. Actual performance ail depend on the installation layout, the fixtures, and the condition of the cable. If the wire diameter you use is thinner than the wire diameter recommended in the table, it may cause the flickering of the end lamps.
