4. Funcionament

This section describes how to configure and operate your UTR-433 timer.

4.1 Funcions clau

• SET: Enters programming mode or confirms a setting.
• MAJÚS: Moves cursor or shifts digits during parameter setting.
• INC (Increment): Increases the value of the selected digit or parameter.
• ENT/RST (Enter/Reset): Confirms a setting or initiates a reset function.

4.2 Modes de programació

The UTR-433 supports several operating modes. To select a mode:

1. Premeu el botó SET key to enter programming mode.
2. Navigate through the parameters using MAJÚS i INC until you reach the 'Operating Mode' setting.
3. Ús INC to select one of the following modes:
   • Delayed ON: The output relay activates after a set delay time once the input pulse is received.
   • OFF retardat: The output relay deactivates after a set delay time once the input pulse is received.
   • Cyclic On Timer: The relay cycles ON for a set time, then OFF for a set time, continuously.
   • Cyclic Off Timer: The relay cycles OFF for a set time, then ON for a set time, continuously.
4. Premeu ENT/RST to confirm the selection and exit programming mode.

4.3 Configuració de l'interval de temps

The timer's range can be set in seconds, minutes, or hours with varying decimal precision.

1. Enter programming mode using the SET clau.
2. Locate the 'Time Range' parameter.
3. Ús INC to cycle through options like 9.99 Sec, 99.9 Sec, 999 Sec, 9.59 Min, 99.9 Min, 999 Min, 9.59 Hrs, 99.9 Hrs, 999 Hrs.
4. Confirmeu la vostra selecció amb ENT/RST.

4.4 Counting Direction and Memory

• Counting Direction: The timer can be configured to count UP or DOWN. Access this setting in programming mode and use INC per alternar entre opcions.
• Memòria: The memory function (YES/NO) determines if the timer retains its count or state after a power cycle. Configure this setting in programming mode as needed.

4.5 Opcions de restabliment

• Front Panel Reset: Prement el ENT/RST key on the front panel can reset the timer, depending on configuration.
• Terminal Reset: An external reset signal can be applied to the dedicated reset terminals (6 and 7) for remote resetting.

5. Manteniment

The UTR-433 timer is designed for reliable operation with minimal maintenance.

• Neteja: Keep the timer's display and housing clean. Use a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Condicions ambientals: Ensure the operating environment adheres to the specified temperature (0°C to 55°C) and humidity (up to 95% RH non-condensing) limits to prevent damage and ensure longevity.
• Inspecció: Periodically check electrical connections for tightness and signs of wear.

6. Solució De Problemes

If you encounter issues with your UTR-433 timer, consider the following basic troubleshooting steps:

• Sense alimentació/pantalla: Check the auxiliary supply connections (Terminals 1 and 2) and ensure the voltage is within the 100-270V AC range. Verify the power source is active.
• Horari incorrecte: Review the programmed time range and operating mode settings. Ensure the input pulse is correctly detected.
• Relé no activat: Check the relay output connections (Terminals 8, 9, 10, 11, 12). Verify the operating mode and set time are correct, and the timer has reached its activation condition.
• Input Not Detected: Ensure the input sensor (Micro Switch, Limit Switch, Proximity) is correctly wired to Terminals 4 and 5 (GND) and is functioning properly. Check the +12V supply if using an active sensor.
• El dispositiu no respon: Attempt a front panel reset. If the issue persists, power cycle the device.
