Product Overview
The Perry Astro-Lux-Time switch features a clear LCD display and intuitive button interface for programming. It is designed for DIN rail mounting within electrical enclosures.
Components:
- LCD Display: Shows current time, date, program status, and menu options.
- MENU Button: Accesses the main programming menu.
- Arrow Buttons (Up/Down): Navigate through menu options and adjust values.
- OK Button: Confirms selections and saves settings.
- RESET Button: Resets the device to factory defaults (use with caution).
- Terminal Blocks: Connections for power supply and load. Numbered 1-10.
Setup
1. Installation:
- Mounting: Securely mount the time switch onto a standard 35mm DIN rail within an electrical distribution board or enclosure.
- Wiring:
- Connect the main power supply (Live and Neutral) to the designated input terminals (refer to the wiring diagram on the device or packaging).
- Connect the load to the output terminals. Ensure the load's current and voltage ratings do not exceed the switch's specifications.
- If using the lux function, connect the external lux sensor to its dedicated terminals (if applicable to your model).
- Power On: Restore power to the circuit. The display should illuminate.
2. Initial Configuration:
- Language Selection: Upon first power-up, the device may prompt for language selection. Use arrow buttons to select and OK to confirm.
- Date and Time Setting:
- Navigate to the "Time/Date" menu.
- Adjust year, month, day, hour, and minute using the arrow buttons. Confirm each setting with OK.
- Geographic Location (for Astro function):
- Access the "Astro" or "Location" menu.
- Select your country and city from the pre-programmed list. If your exact location is not available, choose the nearest major city or manually enter latitude/longitude if the device supports it.
- This setting is crucial for accurate sunrise/sunset calculations.
Operating Instructions
1. Programming Modes:
The device typically supports multiple programming modes:
- Astro Mode: Switches the load ON/OFF based on calculated sunrise and sunset times for your configured location.
- Timed Mode: Allows setting specific ON/OFF times for each day of the week or for specific days.
- Lux Mode (if applicable): Controls the load based on the ambient light level detected by an external sensor.
2. Setting Programs:
- Press the MENU button to enter the main menu.
- Navigate to "Programs" or "Schedules" using the arrow buttons and press OK.
- Select the desired program number (e.g., P1, P2) or create a new one.
- Choose the program type (Astro ON/OFF, Timed ON/OFF, Lux ON/OFF).
- For Timed Programs: Set the desired ON time and OFF time. Select the days of the week for which the program should be active.
- For Astro Programs: You may have options for offset (e.g., 15 minutes before sunset).
- Confirm and save each program step with the OK button.
3. Manual Override:
The device usually has a manual override function to temporarily switch the load ON or OFF, irrespective of the programmed schedule.
- Locate the manual override button (often labeled with a hand icon or "MANU").
- Pressing it typically toggles the output state (e.g., from OFF to ON, or ON to OFF).
- The display will indicate the manual override status. The program will resume control at the next scheduled event.
Maintenance
The Perry Astro-Lux-Time switch requires minimal maintenance.
- Cleaning: Gently wipe the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery: The device contains an internal battery for retaining settings during power outages. This battery is typically long-lasting and not user-replaceable. If the display goes blank or settings are lost frequently during power interruptions, contact a qualified technician for service.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power supply. | Check circuit breaker and wiring connections. Ensure power is supplied to the correct terminals. |
| Load does not switch ON/OFF as programmed. | Incorrect program settings; Manual override active; Wiring error; Incorrect date/time/location. | Verify program times and days. Check if manual override is active. Inspect load wiring. Re-check date, time, and geographic location settings. |
| Time or settings are lost after power outage. | Internal battery depleted. | The internal battery may need replacement by a qualified technician. |
| Astro function is inaccurate. | Incorrect geographic location set. | Verify and correct the geographic location (country/city or latitude/longitude) in the settings. |
