Safety Information
WARNING: Risk of Electric Shock. Read all instructions before installation and operation.
- Always disconnect power at the circuit breaker before installing or servicing the transformer.
- Installation must be performed by a qualified electrician in accordance with all local and national electrical codes.
- Do not operate the transformer with damaged cords or wires.
- Ensure the transformer is mounted securely to a stable surface.
- This transformer is designed for outdoor use. Ensure all connections are watertight.
Setup
1. Mounting the Transformer
The DX-150-M transformer can be mounted as a chassis mount or rack mount. Select a suitable location that is protected from direct impact and allows for proper ventilation. The dimensions of the unit are 5.04"D x 7.14"W x 11.4"H. Use appropriate hardware to secure the transformer firmly to a wall or other stable structure.

2. Electrical Connections
Ensure the main power supply is OFF before making any electrical connections. The transformer operates on a corded electric power source. Connect the low-voltage lighting wires to the appropriate terminals inside the transformer. The unit provides common (C), 12V, 13V, and 14V output terminals to accommodate various lighting requirements. An external input option is also available for integration with other control systems.

3. Initial Power-Up
After all connections are securely made and verified, restore power to the transformer. The digital face-pack will illuminate, indicating the unit is powered on. Follow the on-screen prompts for initial setup, including date, time, and location settings for astronomical timing.
Operating Instructions
The DX-150-M features a digital face-pack for easy programming and control of your lighting system.
1. Digital Face-Pack Control
Navigate through the menus using the control knob and buttons on the face-pack. The display shows current time, date, and programming options. The interface allows for intuitive setup of lighting schedules.

2. Astronomical Timing
The built-in astronomical timing feature automatically adjusts lighting schedules based on local sunrise and sunset times. Ensure your location is correctly set during the initial setup for accurate operation.
3. Event-Based Programming
Program specific lighting events with timed offsets from sunrise or sunset. This allows for customized lighting scenes throughout the day or night. Refer to the on-screen menu for detailed event creation and modification.
4. Manual On/Off
A manual override function is available on the face-pack, allowing you to turn the lights on or off independently of the programmed schedule. This is useful for temporary adjustments or testing.
Maintenance
The DX-150-M transformer is designed for minimal maintenance. However, regular checks can ensure optimal performance and longevity.
- Periodically inspect the transformer housing for any signs of damage or corrosion.
- Ensure all wiring connections remain tight and free from debris.
- Keep the digital face-pack clean and free of dust or moisture. Use a soft, dry cloth for cleaning.
- Do not attempt to open the sealed internal components of the transformer. Refer servicing to qualified personnel.
Troubleshooting
If you encounter issues with your DX-150-M transformer, consider the following common troubleshooting steps:
- No Power to Lights: Check the main power supply at the circuit breaker. Verify all low-voltage wiring connections are secure and not corroded. Ensure the transformer is receiving input power.
- Lights Not Turning On/Off as Programmed: Verify the astronomical timing settings, including your geographical location. Check programmed events for correct times and offsets. Ensure the manual override is not active.
- Display Not Working: Ensure the transformer has power. If the display remains blank or shows errors, contact customer support.
- Flickering Lights: This may indicate a loose connection, an overloaded circuit, or a faulty lamp. Inspect wiring and ensure the total wattage of connected lights does not exceed the transformer's 150 Watt capacity.
