MCC FOR CIP TANK & PUMPS CONTROL

For the provided MCC (Motor Control Center) set up for the CIP (Clean-in-Place) system controlling 6 submersible pumps, tank agitators, and vessel agitators, here’s how it could be configured.

Motor Control Centre Configuration:

• Main Power Supply: The MCC would receive power from the main electrical supply.
• Siemens G120 PM240-2 Power Modules: These modules would serve as the variable speed drives (VSDs) for the submersible pumps, tank agitators, and vessel agitators. Each pump and agitator would be connected to a dedicated PM240-2 power module.
• CU240-E Control Units: The control units would provide the interface for programming and controlling the VSDs. Each PM240-2 power module would be paired with a CU240-E control unit.
• IOP-2 Interfaces: These interfaces would facilitate communication between the control units and the operators or supervisory systems. They provide a means for monitoring and adjusting the VSD parameters.
• Braking Resistors: Braking resistors would be connected to the VSDs to dissipate excess energy during deceleration of the pumps and agitators.
• Output Reactors: Output reactors would be installed to improve the performance and efficiency of the VSDs by reducing harmonics and protecting against voltage spikes.

Pump and Agitator Configuration:

Submersible Pumps (6 in total):

• 3 duty pumps ranging from 7.5 kW to 11 kW.
• 3 standby pumps of similar power ratings.
• Each pump would be connected to a dedicated PM240-2 power module and CU240-E control unit.

Tank Agitator (11 kW):

• The tank agitator would be connected to a separate PM240-2 power module and CU240-E control unit.

Holding Vessel Agitator (2.2 kW):

• The holding vessel agitator would be connected to another PM240-2 power module and CU240-E control unit.

Yogurt CIP Return Pumps:

• The pumps for yogurt CIP return would also be integrated into the MCC setup, each connected to its respective PM240-2 power module and CU240-E control unit.

Overall Functionality:

• The MCC would allow for precise control and monitoring of the pumps and agitators, enabling efficient operation of the CIP system.
• Variable speed drives would optimize energy consumption and provide flexibility in adjusting flow rates and agitation speeds as per process requirements.
• The use of braking resistors and output reactors would ensure smooth operation and protection of equipment.

This configuration provides a comprehensive solution for controlling the CIP system with multiple pumps and agitators, ensuring reliability, efficiency, and ease of maintenance.
