Greetings,


 The HMS PLC code HMS_controls_V23.acd has been modified


Q1 and Q2 Function block page Sheet 33 the connection that defines polarity status has been broken

Q3 Function block page Sheet 34 the connection that defines polarity status has been broken

The Polarity status has to be manual updated whenever the current leads are physically swapped on the Power supplies.


Q1 and Q2 Function block page Sheet 33 the connection between HMI_Polarity_Neg and the BAND has been broken and input2 of the BAND has been set to Zero to prevent the change polarity command from going out.

Q3 Function block page Sheet 34 the connection between HMI_Polarity_Neg and the BAND has been broken and input2 of the BAND has been set to Zero to prevent the change polarity command from going out.


Cheers

Steven
