Jewenwils Low-Voltage Transformer

Important Information

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.

• Do not install within 10 feet (3 m) of a pool, spa or fountain.
• There are no serviceable parts inside the power supply unit. DO NOT DISASSEMBLE.
• Do not repair or tamper with cord or plug.
• Do not submerge transformer in water.
• Do not mount the transformer onto combustible material.
• Do not connect two or more transformers in parallel.
• Do not use the transformer with a dimmer switch.
• Plug the power supply unit directly into a GFCI wet location outlet.
• For use with low voltage outdoor landscape lighting system only.
• The maximum output of this transformer is 120 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 120 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 120 Watt transformer has 120 watt circuits which will power up to 120 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 120 Watt transformer.

Installation

1. 1. Preparing the Cable

   Being careful when splitting it. NOT to expose the copper cable. Remove the landscape cable insulation 1/2 inch (12.7 mm) from both cables and twist ends.

   [Diagram: Shows two wires being carefully stripped to expose copper, with insulation removed to a depth of 1/2 inch.]

2. 2. Connecting the cable to the Transformer

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

   [Diagram: Shows the inside of the transformer with terminal blocks. Two wires are shown being inserted into the terminals. Another small diagram shows a hand gently pulling a connected wire to test its strength.]

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

3. 3. Placing Your Fixtures and Routing the cable

   Lay your fixtures (not included) to your desired location. Be sure they do not exceed the 120-watt rating of the transformer. Coil the rest of the cable after the last fixture.

   [Diagram: Illustrates a landscape layout with a transformer, cables running to multiple fixtures placed among plants and rocks. Arrows indicate the direction of cable routing and where excess cable should be coiled.]

4. 4. Attaching Your Fixtures

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

5. 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.

   [Diagram: Shows the transformer mounted on a wall, with a power cord plugged into an outlet. A measurement line indicates the suggested mounting height of 12 to 48 inches from the ground.]

Operating Instruction

The transformer offers several operating modes:

• 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.

  Note: If the '.' on the display goes off after a few seconds, it means that the wiring of the lamps is abnormal or the wire is broken. You need to cut off the power supply of the transformer to eliminate the abnormal situation, then restart the power supply.

• Figure 3: AUTO MODE

  In this mode, it will take 30 seconds for the transformer to detect the external environment firstly. If it is night, the transformer will start output 30 seconds 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 30 seconds.

• Figure 4 & Figure 5: COUNTDOWN MODE

  In this mode, it will also take 30 seconds for the transformer to detect the external environment firstly. If it is night, the transformer will start output 30 seconds later and the load lamps will light. Then they will turn off automatically when 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 30 seconds, the countdown will end, the transformer will stop output, and the load lamps will go out.

• Figure 6: FAILURE MODE

  When the "F" lights, the outlet is overloaded or short circuit. To solve it, pull out the plug and check the circuit. Connect the power again after troubleshooting; the transformer will reset automatically.

Tips

1. When the transformer is working, the dot in the lower right corner of the display lights up. If the dot is not lit 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 transformer has two outputs with a total output power of 120VA.

Troubleshooting

T1. The display shows "F"

1. Unplug the transformer from the power outlet.
2. Check if the transformer is overloaded or not.
3. Check if there is a short circuit at the transformer terminals.
4. Check whether the connection between the lamp and the buried wire is short-circuited.
5. After troubleshooting, replug the transformer; it will automatically reset.

T2. In ON mode, the load lamp is off, the display shows "0"

1. Unplug the transformer from the power outlet.
2. Check if the transformer terminals are properly connected.
3. Check whether the connection between the lamp and the buried wire is correct.
4. After troubleshooting, replug 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).

1. Unplug the transformer from the power outlet.
2. Check if the transformer terminals are properly connected.
3. Check whether the connection between the lamp and the buried wire is correct.
4. After troubleshooting, replug the transformer into the power outlet.
5. Press the up/down button to enter AUTO mode or COUNTDOWN mode, cover the sensor for more than 30 seconds, 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.
