Opsætning og installation
Proper installation is critical for the safe and effective operation of your time switch. This device is designed for wall mounting.
- Strømafbrydelse: Before beginning any installation, ensure the main power supply to the circuit where the time switch will be installed is turned OFF at the circuit breaker or fuse box. Verify with a voltage tester.
- Montering: Select a suitable indoor location for wall mounting. Secure the steel enclosure firmly to a wall stud or use appropriate wall anchors. The dimensions are approximately 5.13 inches wide by 7.88 inches high by 3.44 inches deep.
- Ledningsføring: Refer to the wiring diagram inside the enclosure (see Figure 1). Connect the electrical wires to the clearly labeled terminals:
- Neutral (A): Connect the neutral wire from your power supply.
- Line (1): Connect the hot (live) wire from your 125 VAC power supply.
- Load (2): Connect the wire leading to the device or circuit you wish to control.
Vigtig: This switch is designed for copper conductors. Do not connect aluminum wires directly to the switch terminals. If aluminum wiring is present, use approved copper-to-aluminum connectors.
- Isolator: Ensure the protective insulator over the wiring terminals is properly in place after wiring. Do not remove this insulator permanently.
- Lukning af kabinet: Close and secure the front cover of the enclosure.
- Strømgendannelse: Genopret strømmen ved hovedafbryderen.
Betjeningsvejledning
The T171 time switch allows for precise scheduling of electrical loads.
- Indstilling af aktuel tid:
Rotate the large yellow 24-hour dial clockwise until the current time aligns with the "TIME SET" arrow located at the top of the dial. The dial is marked with AM/PM indicators.
- Setting ON/OFF Operations:
The dial has small segments around its perimeter. To set an ON time, push an "ON" tripper (usually green or silver) into the desired time slot on the dial. To set an OFF time, push an "OFF" tripper (usually red or black) into the desired time slot. The T171 supports 1 to 10 ON/OFF operations per day. The minimum ON or OFF time is 1 hour.
Note: Trippers are typically supplied with the unit. Additional trippers may be purchased separately if needed for more operations.
- Manuel tilsidesættelse:
A manual lever is provided on the mechanism (see Figure 1). This lever allows you to temporarily override the programmed schedule. Move the lever to the "ON" or "OFF" position as desired. The timer will resume its programmed schedule at the next scheduled ON or OFF event.
- Skip-A-Day Feature:
The T171 is a "24 Hour with Skip A Day" type timer. This feature allows you to prevent the timer from operating on specific days of the week. Consult the detailed instructions provided with your specific unit for setting the skip-a-day pins or segments, if applicable. This typically involves setting small pins on the outer edge of the dial corresponding to days you wish to skip.
Opretholdelse
The Intermatic T171 time switch is designed for long-term, reliable operation with minimal maintenance.
- Rensning: Periodically wipe the exterior of the enclosure with a clean, dry cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning the interior if necessary.
- Inspektion: Annually inspect the wiring connections for tightness and signs of wear or corrosion. Ensure the enclosure remains securely mounted.
- Ingen dele, der kan serviceres af brugeren: The internal mechanism is not user-serviceable. If the unit malfunctions, contact a qualified electrician or Intermatic customer support.
