3. Cynnyrch Drosview
The Intermatic MIL72ESTUZH-120 is a robust 24-hour electromechanical timer module designed for flush or panel mounting within a control panel. It is suitable for light-duty commercial applications requiring precise time control for 120 VAC single-phase circuits. Common uses include lighting, HVACR systems, pumps, motors, and general electrical circuit management.

Delwedd: Blaen view of the Intermatic MIL72ESTUZH-120 timer. The device features a clear protective cover over a black dial. The dial displays a 24-hour format with AM/PM indicators and minute markings. A central clock mechanism with hour and minute hands indicates the current time. The outer edge of the dial contains captive trippers for setting ON/OFF periods. A manual override switch is visible on the right side of the dial.
Nodweddion Allweddol:
- 21 A SPDT Switch: Provides reliable switching for various loads.
- Synchronous Drive with Self-Recharging Battery Backup: Ensures accurate timekeeping and operation during power outages.
- Captive Trippers: Allows for easy setting of 15-minute ON/OFF intervals.
- Diystyru â Llaw: Provides flexibility to temporarily bypass programmed settings.
- Dyluniad Mownt Fflysio: Integrates seamlessly into control panels.

5. Gosod
Cyn i Chi Ddechrau:
- Ensure power is OFF at the main circuit breaker.
- Gwiriwch fod y cyflenwad cyftage matches the timer's rating (120V AC).
- Have appropriate tools ready (screwdriver, wire strippers, etc.).
Mowntio:
- Select a suitable location within a control panel for flush mounting.
- Cut an appropriate opening in the panel according to the timer's dimensions.
- Insert the timer into the opening and secure it using the provided mounting hardware.
Gwifrau:
Refer to the wiring diagram provided with the product packaging for specific connections. General wiring steps include:
- Connect the incoming 120V AC line wire to the designated terminal.
- Cysylltwch y wifren niwtral â'r derfynell niwtral.
- Connect the load wire(s) (e.g., to lights, motor) to the appropriate switched terminals (normally open or normally closed, depending on desired operation).
- Sicrhewch fod pob cysylltiad yn ddiogel ac wedi'i inswleiddio.
After wiring, restore power and proceed to initial setup.
6. Gweithrediad
Gosod Amser Presennol:
- Rotate the entire dial clockwise until the current time aligns with the time indicator arrow (usually a small triangle or line on the stationary part of the timer housing).
- Ensure you distinguish between AM and PM hours on the 24-hour dial.
Setting ON/OFF Programs:
The timer uses captive trippers around the dial to set program times. Each tripper represents a 15-minute interval.
- To set an ON period, push the trippers outwards for the desired duration.
- To set an OFF period, leave the trippers in their inward position for the desired duration.
- The timer will activate the connected load when the dial rotates past an outward-pushed tripper and deactivate it when it rotates past an inward-pushed tripper.
Diystyru â Llaw:
The MIL72ESTUZH-120 features a manual override switch, typically a small lever or button, located on the timer face. This allows you to temporarily switch the load ON or OFF, overriding the programmed schedule without affecting future cycles.
- Move the override switch to the desired position (ON or OFF).
- The timer will resume its programmed schedule at the next scheduled ON or OFF event.
7. cynnal
The Intermatic MIL72ESTUZH-120 is designed for minimal maintenance.
- Glanhau: Periodically wipe the exterior of the timer with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Batri: The unit contains a non-replaceable, self-recharging Nickel Metal Hydride battery for power outage carry-over. No user maintenance is required for the battery.
- Arolygiad: Annually inspect the timer for any signs of damage, loose connections, or unusual operation. If any issues are found, disconnect power and consult a qualified electrician.
