General Wiring Steps:

1. Open the timer box cover.
2. Identify the appropriate wiring diagram for your application (SPDT or DPDT, voltage, and load type).
3. Connect the incoming power supply wires to the designated terminals (e.g., TIMER, COM).
4. Connect the load wires (to your appliance) to the appropriate output terminals (e.g., NO1, NO2, COM1, COM2).
5. Ensure all connections are secure and properly insulated.
6. Close the timer box cover securely.

Note: Jumper wires and strain reliefs are typically required for installation and are not included with the timer. Ensure these are sourced and installed correctly.

Operating Instructions

Setting the Current Time

Rotate the dial clockwise until the arrow on the timer indicates the current time. The dial represents a 24-hour cycle.

Programming ON/OFF Times

1. The timer dial has 96 pins around its circumference, each representing a 15-minute interval.
2. To set an "ON" period, push the pins down for the desired time duration. Each pushed-down pin corresponds to 15 minutes of "ON" time.
3. To set an "OFF" period, leave the pins in the "UP" position for the desired time duration.
4. You can program up to 48 ON/OFF cycles per day.

Using the Manual Switch (Override)

The timer features a manual switch with three positions:

• AUTO: In this position, the timer will operate according to your programmed ON/OFF settings.
• ON: This position overrides the timer and keeps the connected device continuously ON.
• OFF: This position overrides the timer and keeps the connected device continuously OFF.

Always return the switch to the "AUTO" position for programmed operation.

Power Failure

In the event of a power failure, the timer will stop. After power is restored, rotate the dial clockwise until the arrow indicates the current time to reset the timer's internal clock.

Maintenance

The BN-LINK U49 Mechanical Timer Box requires minimal maintenance. To ensure optimal performance and longevity:

• Periodically inspect the timer box for any signs of damage, such as cracks in the casing or loose wiring.
• Keep the exterior of the timer clean by wiping it with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
