Since jaws are moving to both directions there is nothing wrong with solenoids.
Check your setup.
To be short, I will explain you the clamping philosophy related to setup of limit swithes.
1. OD clamping. Chuck open means draw bar is advanced forward and the respective LS is activated.
Chuck clamped means draw bar is pulled back and no limit swith is activated.
Workpiece lost is when draw bar is pulled back and the limit switch activated. Means - the drawbar travelled full way back and there is no workpiece in the jams. Alarm, machine stop instantly.
2. ID clamping. Chuck open means draw bar is pulled back and the respective LS is activated.
Chuck clamped means draw bar is advanced forward and no limit swith is activated.
