Figure 1: Front view of the Dabmar LVT100 Low Voltage Transformer. The clear protective cover reveals the control panel, which includes a circuit breaker reset button on the left, a photocell sensor, and a rotary switch on the right for selecting operating modes (AUTO, ON, OFF) and timer settings (4H, 8H).

Key Components:

• Circuit Breaker Reset Button: Labeled "RESET", this button is used to restore power if the circuit breaker trips due to an overload or short circuit.
• Photocell Sensor: Detects ambient light levels to enable automatic operation (AUTO mode).
• Mode/Timer Selector Dial: A rotary switch with settings for:
  • OFF: Turns the transformer output off.
  • ON: Provides continuous power output.
  • AUTO: Activates the photocell. The transformer will turn on at dusk and off at dawn.
  • 4H (4 Hours): Turns on at dusk via photocell and stays on for 4 hours.
  • 8H (8 Hours): Turns on at dusk via photocell and stays on for 8 hours.
• Power Cord: Connects the transformer to a standard electrical outlet.
• Low Voltage Output Terminals: (Not visible in image, but implied) Connections for low voltage landscape lighting cables.

Setup and Installation

1. Choose a Location: Select a suitable location for the transformer. As per the product label, it is suitable for both indoor and outdoor use. For outdoor installation, choose a location that is protected from direct heavy rain and where the photocell can receive adequate ambient light. The unit is designed for wall mounting.
2. Mount the Transformer: Securely mount the transformer to a wall or sturdy surface using appropriate fasteners (not included) through the mounting holes. Ensure it is mounted vertically with the power cord facing downwards to prevent water ingress.
3. Connect Low Voltage Cables: Route your low voltage landscape lighting cables to the transformer's output terminals. Ensure all connections are secure and properly insulated. Refer to your lighting fixture's instructions for proper wiring. Do not exceed the total bulb usage of 100 watts.
4. Plug In: Once all low voltage connections are made and secured, plug the transformer's power cord into a standard 120V AC grounded electrical outlet.

Operating Instructions

The Dabmar LVT100 transformer offers several operating modes via its selector dial:

• OFF Mode: Rotate the dial to "OFF". The transformer will not provide power to the lights.
• ON Mode: Rotate the dial to "ON". The transformer will provide continuous power to the lights, regardless of light conditions.
• AUTO Mode (Photocell): Rotate the dial to "AUTO". The built-in photocell will detect ambient light. The lights will automatically turn on at dusk and turn off at dawn. Ensure the photocell is not obstructed and is exposed to natural light.
• 4H Mode (4-Hour Timer): Rotate the dial to "4H". The photocell will detect dusk, turn on the lights, and keep them on for approximately 4 hours before automatically turning off.
• 8H Mode (8-Hour Timer): Rotate the dial to "8H". The photocell will detect dusk, turn on the lights, and keep them on for approximately 8 hours before automatically turning off.

Circuit Breaker Reset: If the lights go out unexpectedly, check the circuit breaker reset button. If it has popped out, press the "RESET" button firmly to restore power. This usually indicates an overload or a short circuit in your lighting system. Address the cause of the overload before resetting.

Maintenance

• Cleaning: Periodically clean the exterior of the transformer with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the photocell lens is clean and free of debris for proper operation.
• Photocell Obstruction: Regularly check that the photocell is not obstructed by dirt, leaves, or other objects that could prevent it from sensing light correctly.
• Cable Inspection: Periodically inspect the low voltage cables and connections for any signs of damage, fraying, or corrosion. Repair or replace damaged cables immediately.
• Wattage Check: Ensure the total wattage of connected lights does not exceed the transformer's maximum capacity of 100 watts.
