5. Setup and Installation

This timer is designed for surface mounting. Ensure the mounting surface is stable and suitable for electrical installations.

1. Power Disconnection: Before beginning any installation, ensure the main power supply to the circuit is turned off at the circuit breaker. Verify with a voltage tester.
2. Mounting Location: Choose a suitable, dry, and easily accessible location for mounting the timer. Mark the drilling points for the mounting screws.
3. Secure Mounting: Drill pilot holes if necessary and securely fasten the timer to the surface using appropriate screws.
4. Wiring:
   • Open the terminal cover of the timer.
   • Connect the incoming live (L) and neutral (N) wires to the designated input terminals.
   • Connect the live (L') and neutral (N') wires of the load (e.g., light fixture, appliance) to the designated output terminals.
   • Ensure all connections are tight and secure. Refer to the wiring diagram inside the timer's terminal cover for precise connections.
5. Close Cover: Replace the terminal cover securely.
6. Power Restoration: Restore power at the main circuit breaker.

6. Operating Instructions

The CRONO QRD timer operates on a 24-hour analogue dial system.

1. Set Current Time: Rotate the outer dial clockwise until the current time aligns with the small arrow or marker on the timer's body. The dial typically has markings for hours (e.g., 0-24) and possibly minutes.
2. Program ON/OFF Times: The dial is surrounded by small segments or pins.
   • To set an "ON" period, push the corresponding segments/pins outwards.
   • To set an "OFF" period, leave the segments/pins pushed inwards.
   • Each segment typically represents a specific time interval (e.g., 15 minutes).
3. Manual Override (if applicable): Some models may include a manual override switch (e.g., ON/AUTO/OFF). Set this switch to "AUTO" for programmed operation. Use "ON" or "OFF" for continuous operation or to temporarily disable the timer.
4. Verification: Observe the timer's operation over a short period to ensure it switches the load ON and OFF according to your programmed schedule.

7. Maintenance

The ORBIS CRONO QRD timer requires minimal maintenance.

• Cleaning: Disconnect power before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically check for any signs of damage, loose connections, or overheating. If any issues are observed, disconnect power and consult a qualified electrician.

8. Troubleshooting

If the problem persists after attempting these solutions, please contact ORBIS customer support or a qualified electrician.
