Dear Teera pong,
Following options are required to be incorporated in the all new Systems you are supplying now. also let me know how to upgrade existing supplied system recently.
1. Connecting existing stirrer to rotate as per pre set timings.- Confirm whether this option is avaialble with the existing PLC?
2. Temperature Indication and control of existing 2 way valve.
3. In Control Panel of In line pump we should be able ON/OFF Main Electrical Pumps. This option is available with earlier supplied systems.
Also when we are commissioning the newly supplied Electrical pumps we are finding liquid overflowing from Motor side ( above overflow hole) when the liquid level is high in the tank even when PUMP is OFF Condition. May be gasket between Pump and motor is not SEALED properly. This is not acceptable, you need revert us back to solve this Issue.
Thanks for Support,
Umesh Kulal
