4. 설치 및 설정
4.1 안전 예방 조치
- 경고: Disconnect power at the circuit breaker or fuse box before installing or servicing the timer. Failure to do so may result in serious injury or death.
- 설치는 모든 국가 및 지역 전기 규정에 따라 자격을 갖춘 전기 기술자가 수행해야 합니다.
- 운영 볼륨 확인tage of the timer (240V) matches the supply voltage.
4.2 장착
The MIL72ASTUZH-240 timer module is designed for installation inside a control panel. It supports two mounting methods:
- 표면 실장: Secure the timer directly to a flat surface within the control panel using appropriate fasteners (not included).
- DIN 레일 마운트: Attach the timer to a standard DIN rail within the control panel. Ensure the timer is securely clipped onto the rail.

4.3 배선
Connect the timer to the 240 VAC power supply and the load using the 1/4-inch quick-connect terminals. Refer to the wiring diagram provided with the product packaging for specific connection details. Ensure all connections are tight and secure.
- Identify the Line (L1, L2) and Load terminals.
- Connect the incoming 240V power to the appropriate Line terminals.
- Connect the device to be controlled (load) to the Load terminals.
5. 사용 설명서
5.1 시간 설정
Rotate the dial clockwise until the current time aligns with the time indicator arrow on the timer face. The dial is marked for 24 hours.
5.2 켜짐/꺼짐 시간 프로그래밍
The timer uses captive trippers for programming. Each tripper represents a 15-minute interval.
- 설정하려면 ON period, push the trippers outwards (away from the center) for the desired duration.
- 설정하려면 끄다 period, leave the trippers in their inward position (towards the center).
- Ensure that the desired ON/OFF periods are clearly defined by the tripper positions.
5.3 수동 오버라이드
The MIL72ASTUZH-240 features a 3-way manual override switch. This allows you to temporarily change the timer's state without altering the programmed schedule.
- Consult the timer's face or specific markings for the exact positions of the 3-way override. Common positions include:
- 에: Forces the connected load to remain ON, regardless of the program.
- 자동 : Allows the timer to follow its programmed schedule.
- OFF : Forces the connected load to remain OFF, regardless of the program.
- To return to automatic operation, set the override switch to the "AUTO" position.
6. 유지관리
The Intermatic MIL72ASTUZH-240 is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance.
- 청소: Keep the timer free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
- 사이: 주기적으로 전기 연결부를 점검하여 견고성과 부식 징후가 있는지 확인하세요.
- 배터리: The unit contains a non-replaceable Nickel Metal Hydride battery. This battery is primarily for internal clock operation during power outages and is not user-serviceable. The synchronous drive means the main timing function does not rely on this battery for continuous operation.
- 환경 조건: Ensure the timer is operated within its specified environmental conditions (e.g., temperature, humidity) to prevent damage.
7. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| Timer not operating / Load not switching | No power supply; Incorrect wiring; Manual override engaged; Trippers not set correctly. |
|
| Load remains ON or OFF continuously | Manual override engaged; Trippers stuck or incorrectly set. |
|
| Timer dial not advancing | 타이머에 전원이 들어오지 않습니다. | Verify power supply to the timer. |
If troubleshooting steps do not resolve the issue, contact a qualified electrician or Intermatic customer support for assistance.
