INTRODUCTION:

In the realm of maintaining operational efficiency in industrial environments, encountering issues with critical machinery can be a common occurrence. One such challenge arises when the CSF/CSD machine fails to initiate upon pressing the start button, accompanied by an alarm message displayed on the Human Machine Interface (HMI) screen. This technical guide outlines a systematic approach to rectify this situation by addressing a specific concern related to the thermal relays. By following the steps detailed below, technicians can effectively diagnose and resolve the issue, ensuring the swift restoration of the machine's functionality.

PROCEDURE: Thermal Relay Reset

Step 1: Inspection of Electrical Cabinet Begin the diagnostic process by gaining access to the electrical cabinet housing the CSF/CSD machine's control components. Locate the section dedicated to thermal relays, which play a crucial role in safeguarding the machinery against overheating and electrical abnormalities.

Step 2: Identification of Thermal Relay Status Within the thermal relay section, observe a small white flap designed to indicate the operational status of the thermal relays. When the system is prepared for operation, this flap should be extended outward. Identify any thermal relay that appears to be in a deactivated state, as indicated by the position of the white flap.

Step 3: Execution of Thermal Relay Reset For the identified inactive thermal relay, initiate the reset process by engaging a white reset button situated on the relay itself. This strategic button press serves as a means to reinitialize the thermal relay, potentially alleviating any disruptions that hindered its functionality.

Step 4: Closure of Electrical Cabinet and System Reset After successfully executing the thermal relay reset, secure the electrical cabinet by closing it. Proceed by activating the system reset through the designated reset button. With the prescribed actions completed, the CSF/CSD machine should be primed to resume its intended operations seamlessly.

CONCLUSION:

The provided technical guide underscores a methodical approach to address a specific malfunction encountered when initiating the CSF/CSD machine. By focusing on the thermal relays and their associated reset procedure, technicians can systematically diagnose and rectify issues, promoting the efficient functioning of the industrial apparatus. Following these outlined steps serves as a testament to the significance of a well-structured troubleshooting process in ensuring the continued productivity of critical machinery.

If the CSF/CSD machine is not working when you press the start button and you notice this alarm message on the HMI screen, here are the steps you must to follow.
