- Remove the front cover of the time switch.
- Knock out the appropriate conduit holes for wiring entry.
- Connect the incoming LINE (hot) wire to the terminal labeled 'LINE'.
- Connect the NEUTRAL wire to the terminal labeled 'NEUTRAL'.
- Connect the LOAD (to appliance/fixture) wire to the terminal labeled 'LOAD'.
- Ensure all connections are tight and secure.

Operating Instructions
The Woods 59101WD uses a mechanical dial for setting ON/OFF times.
Setting the Current Time:
- Rotate the outer dial clockwise until the current time aligns with the 'TIME SET' arrow (usually located near the top of the dial). The dial is marked with AM/PM indicators.
Programming ON/OFF Times:
- The outer dial has segments around its perimeter. Each segment represents a 30-minute interval.
- To set an 'ON' period, push the pins (segments) outwards for the desired duration.
- To set an 'OFF' period, leave the pins (segments) in their inward position.
- The timer will activate the connected device when the dial rotates to an 'ON' segment and deactivate it when it rotates to an 'OFF' segment.
- The settings will repeat daily.
Manual Override:
A manual override switch is typically located on the side of the timer mechanism. This allows you to temporarily turn the connected device ON or OFF, overriding the programmed settings without affecting the timer's schedule. Return the switch to the 'TIMER' position for automatic operation.
Maintenance
The Woods 59101WD is designed for minimal maintenance. Regular inspection is recommended.
- Periodically inspect the time switch for any signs of damage, loose connections, or wear.
- Keep the enclosure clean and free of dust and debris. Use a dry cloth for cleaning.
- Do not use liquid cleaners or solvents.
- Ensure the lockable cover is securely closed to protect internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn ON/OFF at programmed times. | Incorrect time setting on dial. Pins not pushed out/in correctly. Manual override switch is engaged. | Verify current time is set accurately. Ensure pins are correctly set for ON/OFF periods. Check manual override switch position; return to 'TIMER' for automatic operation. |
| Device does not turn ON at all. | No power to the time switch. Loose wiring connections. Overload or faulty device. | Check circuit breaker/fuse. Turn off power at main panel and check all wiring connections. Test the connected device directly to ensure it is functional. |
| Timer dial is not rotating. | No power to the time switch. Internal mechanical issue. | Check power supply. If power is present and dial is not moving, the unit may require service or replacement. |
