Hi we want to change a Grammatic on a GSV 331 to a standard PLC, the customer
what to uniform his range of PLC to 1.

We have previous developed a standard PLC unit for a Vilter screwcompressor.

My problem is the calculation of where the Volume is to be compared to Vi ratio and
where the Cap is. For Vilter it is a table which we lookup.

Impossible to get information from the now owner of the compressors. Gram was sold to York which was sold to JCI. Have been in touch with JCI they want help.

Any help out here?
