dewenwils HSLT05A Low Voltage Transformer

Please pay attention to the warning signs.
Read the instructions with caution before operating and keep it properly.

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 300 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 300 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 300 Watt transformer has 300 watt circuits which will power up to 300 watts of light.
• To make sure the maximum number of fixtures can be safely connected to this transformer, add up the individual wattage of all the fixtures.
• The total wattage of your fixtures must not exceed output capacity of the 300 Watt transformer.

INSTALLATION

Preparing the Cable

Be careful when splitting the landscape cable. Do NOT expose the copper cable. Remove 1/2 inch of insulation from both cables and twist the ends.
– DO NOT MIX SOLID AND STRANDED TYPE WIRES IN THE SAME
TERMINAL BLOCK SCREW.

• Split the cable 2″ and strip ½” of insulation from wire ends.
• Insert the stripped wire ends into the terminals.
• Tighten screws securely. SCREW
• CONNECTIONS MUST BE TIGHTENED 18lb-in.
• Plug transformer power cord into a 120V GFCI protected receptacle marked ” wet location.”

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.

NOTE: Gently pull on the landscape cable to verify if the connection is strong.

• This transformer has multiple output terminals: 2 x Common (COM), 12V & 15V. The total load applied to the two commons must not exceed 300VA.
• Different voltage terminals can be used simultaneously as long as the total lamp VA does not exceed 300VA. One wire of each cable needs to be connected to a common. Make sure all unused taps (leads) are separately insulated.

Placing Your Fixtures and Routing the cable

• Lay your fixtures (not included) to your desired location.
• Be sure they do not exceed the 300-watt rating of the transformer.
• Coil the rest of the cable after connecting the last fixture.

Attaching Your Fixtures

• Turn the transformer on. Use the cable connectors to attach your fixtures with the cable. Then it will light up.

Mounting the Transformer

• Mount the transformer directly to a solid wall surface using supplied screws and mounting bracket with slotted holes. 12 inches to 48 inches (0.3m to 1.2m) height from the ground would be recommended.

Operating Instructions

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, the transformer will take 30s to detect the external environment firstly. If it is night, the transformer will start output 30s later, then the load lamps will light on automatically and off at dawn. If it is during the day, 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, the transformer will also take 30s to detect the external environment firstly. If it is night, the transformer will start output 30s later and the load lamp will light. Then it will turn off automatically when the the countdown is over. If it is during the day, 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 transformer will stop output, and the load lamp will go out.

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. After the transformer has been working in the current mode for 24 hours, the transformer will remember the current working mode. When the transformer powers on again, the transformer will enter the working mode before the power failure.

3. The display shows “F”
   Step 1: Unplug the transformer from the power outlet.
   Step 2: Check if the transformer is overloaded.
   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: After troubleshooting, replug the transformer, it will automatically reset.

4. In ON mode, the load lamp is off, the display shows “0”
   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
   Step 4: After troubleshooting, replug the transformer, it will automatically reset.

5. 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 will 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.
