1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of the AUTONICS AT11DN-24-240 Multi-Function Timer. This device is designed for precise timing control in various industrial and commercial applications, offering a wide timing range from 0.05 seconds to 100 hours and operating on 100VAC-240VAC power.
2. Safety Precautions
Read these safety precautions carefully before using the product to ensure proper and safe operation. Failure to follow these instructions may result in electric shock, fire, or product damage.
- Electrical Safety: Ensure all wiring is performed by qualified personnel in accordance with local and national electrical codes. Disconnect power before installation, inspection, or maintenance.
- Power Supply: Verify that the power supply voltage matches the product's specified voltage range (100VAC-240VAC). Incorrect voltage can cause damage.
- Installation Environment: Install the timer in an environment free from excessive vibration, dust, moisture, corrosive gases, or direct sunlight. Ensure adequate ventilation.
- Terminal Connections: Securely fasten all terminal connections to prevent loose contacts, which can lead to overheating or malfunction.
- Load Capacity: Do not exceed the specified contact rating (5A resistive load). Overloading can damage the internal relay.
3. Product Overview
The AUTONICS AT11DN-24-240 is a compact multi-function timer featuring a clear rotary dial for time setting and various indicators for operational status.
Figure 1: Front panel of the AUTONICS AT11DN-24-240 Multi-Function Timer.
This image displays the front panel of the AUTONICS AT11DN-24-240 Multi-Function Timer. Visible elements include the central rotary dial for time setting, marked with a scale from 0 to 10. Above the dial, there are 'POWER' and 'RUN' indicator lights. To the right, an 'OUT' indicator and a 'MODE' selector switch are present. The brand name 'Autonics' is printed at the bottom right of the panel.
3.1. Front Panel Components
- Time Setting Dial: Rotary dial for setting the desired time value within the selected range.
- POWER Indicator: Illuminates when power is supplied to the timer.
- RUN Indicator: Illuminates during the timing operation.
- OUT Indicator: Illuminates when the output relay is activated.
- MODE Selector: Switch to select the desired operating mode (e.g., ON-delay, Interval).
4. Setup
4.1. Mounting
The AT11DN-24-240 timer is designed for panel mounting. Ensure sufficient space for wiring and ventilation. Secure the timer using the provided mounting hardware.
4.2. Wiring
Refer to the wiring diagram printed on the side of the timer or in the detailed product datasheet for specific terminal connections. Common connections include:
- Power Supply (100-240VAC): Connect the main power supply to the designated terminals.
- Output Contacts: Connect the load to the normally open (NO) and common (COM) terminals of the output relay. Ensure the load current does not exceed 5A resistive.
- Control Input (if applicable): Some modes may utilize external control inputs (e.g., START, RESET). Connect these as per the specific mode's requirements.
Warning: Ensure power is disconnected before performing any wiring.
4.3. Initial Settings
- Time Range Selection: The timer supports various time ranges (e.g., seconds, minutes, hours). Select the appropriate range using the internal DIP switches or external selector, if present (refer to the detailed product datasheet for specific model configuration).
- Operating Mode Selection: Use the 'MODE' selector switch on the front panel to choose the desired timing function (e.g., ON-delay, OFF-delay, Interval, Flicker).
5. Operating Instructions
5.1. Setting the Time
Rotate the central time setting dial to the desired time value. The dial is typically marked with a scale from 0 to 10, representing a percentage of the selected time range. For example, if the range is 10 minutes, setting the dial to '5' would correspond to 5 minutes.
5.2. Powering On
Once wiring and settings are complete, apply power to the timer. The 'POWER' indicator will illuminate.
5.3. Timing Operation
Depending on the selected mode:
- For ON-delay mode, timing begins immediately upon power application or trigger. The 'RUN' indicator will illuminate.
- Upon completion of the set time, the output relay will activate, and the 'OUT' indicator will illuminate.
- For other modes, refer to the specific timing chart in the detailed product datasheet.
6. Maintenance
The AUTONICS AT11DN-24-240 timer is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Cleaning: Gently wipe the exterior of the timer with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect wiring connections for tightness and signs of wear or damage. Check for any unusual sounds or odors during operation.
- Storage: If storing the timer, keep it in a dry, dust-free environment within the specified temperature and humidity ranges.
7. Troubleshooting
If the timer does not operate as expected, consult the following table before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer does not power on (POWER indicator off) | No power supply; Incorrect wiring; Blown fuse (external) | Check power source; Verify wiring connections; Inspect external fuse. |
| Timing does not start (RUN indicator off) | Incorrect mode selection; No trigger signal (if applicable); Faulty unit | Verify operating mode; Check trigger input; Contact support if unit is faulty. |
| Output does not activate (OUT indicator off) | Timing not complete; Incorrect load wiring; Overloaded output | Wait for timing cycle to complete; Check load connections; Ensure load current is within 5A resistive. |
| Inaccurate timing | Incorrect time setting; Incorrect time range selection | Adjust time setting dial; Verify time range selection. |
