ICM kontrole ICM203 Uputstvo za upotrebu tajmera za kašnjenje pri prekidu

1. Uvod

The ICM Controls ICM203 is a universal voltage delay on break timer designed to protect compressors from damage caused by rapid short cycling. This anti-short cycle relay ensures that the compressor remains off for a set period after power interruption, allowing system pressures to equalize before restarting. It operates across a wide voltage range and features an adjustable delay setting.

Opći koraci instalacije:

1. Isključite napajanje: Ensure all power to the HVAC unit or compressor is completely disconnected at the circuit breaker.
2. Locate Compressor Contactor: Identify the low voltage control circuit for the compressor contactor.
3. Žičana veza: The ICM203 features a simple 2-wire hookup. Connect the two wires of the ICM203 in series with the 24 VAC control circuit that energizes the compressor contactor coil. This means the timer will interrupt the control voltage to the contactor.
4. Voltage Izbor (ako je primjenjivo): The ICM203 is universal voltage. For 120/240 VAC applications, ensure the red jumper wire is correctly configured or cut as indicated on the device label, if necessary for your specific voltage. Refer to the device's printed instructions for precise wiring diagrams.
5. Montaža: Securely mount the ICM203 in a suitable location within the control panel or near the compressor, ensuring it is protected from environmental elements.
6. Vrati snagu: Once wiring is complete and verified, restore power to the unit.

5. Operacija

The ICM203 operates automatically once installed. Its primary function is to enforce a delay before the compressor can restart after a power interruption or a call for cooling is removed and then immediately reapplied. This delay protects the compressor from short cycling.

Adjusting the Delay Time:

The delay time is adjustable using the red dial located on the front of the unit. The dial is marked in minutes, typically ranging from 0.03 minutes (approximately 1.8 seconds) to 10 minutes (600 seconds). To adjust the delay:

1. Locate the Dial: Find the red adjustment dial on the face of the ICM203.
2. Rotate to Desired Setting: Carefully rotate the dial using a small screwdriver or similar tool to align the indicator with the desired delay time in minutes. Common settings are often between 3 to 5 minutes to allow sufficient pressure equalization.
3. Potvrdite rad: After setting, observe the system's behavior to ensure the delay functions as intended before the compressor restarts.

6. Održavanje

The ICM Controls ICM203 Delay on Break Timer is a solid-state device designed for reliable, maintenance-free operation. No routine maintenance is required. Periodically, ensure that electrical connections remain secure and free from corrosion. If the unit appears damaged or is not functioning correctly, it should be inspected by a qualified technician.

7. Otkrivanje problema

If the ICM203 is not functioning as expected, consider the following:

• No Delay: Verify the dial is set to a non-zero delay time. Ensure the unit is correctly wired in series with the compressor contactor's control circuit.
• Kompresor se ne pokreće: Check for proper power supply to the ICM203. Ensure all wiring connections are secure. If the delay period has elapsed and the compressor still does not start, investigate other components of the HVAC system.
• Incorrect Delay Time: Re-adjust the dial to the desired setting. Note that the adjustment at the very low end of the scale can be sensitive.
• Unit Damage: Visually inspect the ICM203 for any signs of physical damage or burning. If damaged, replace the unit.

For persistent issues, it is recommended to consult a qualified HVAC technician.
