Probable Causes (ranked)

Fix Steps

  1. 1 Check air pressure at transfer — gauge should read plant spec
  2. 2 Manually actuate solenoid — use override button on valve body
  3. 3 Check position confirm sensors — clean and adjust as needed
  4. 4 Inspect under pop-up for trapped products or debris
  5. 5 If cylinder slow, check flow control valves — may be closed too much
  6. 6 Check PLC output — verify output LED is ON when transfer commanded

Field Trick

Hit the solenoid manual override. If the transfer pops up, the problem is electrical (PLC output or solenoid driver). If nothing happens, check air first, then the cylinder.
