Hi,
 The JT valve #1 connector is miss-wired.
Pins F and G are swapped on the connector. for cable 402-08.

This particular wiring setup allows the motor to still operate: close = close and open = open, but nullifies the action of the limit switches. This could have serious damaged the internal bellows of the JT stem assembly.

The remainder of the JT actuators have been tested and the valve position calibrated.

Also there is no  valve setting capabilities for the two HX valves in the HMI. No POSP or gain setting menus for them.

I am still working on getting any of the valves to operate from the HMI screens. The POSP functions blocks are not responding yet within the PLC.

Steven
