Service Information:

If this error is reported, the picker wrist cylinder is probably faulty.

If there are problems during a pick, the firmware does extra steps to try and figure out the real problem. For this error to be reported, the picker will have tried to grab the plate, but the wrist timed out moving out. Even after releasing vacuum, the wrist still wouldn't come out. The picker head was moved out, then back in to try and re-seal the wrist cylinder. The wrist was then moved back in to grab the plate, then the wrsit was moved out. Still the wrist wouldn't come out. This could be a bad sensor, but the sensor is checked before the wrist moves in the first time to grab the plate, and it had read TRUE at that time.

Cause:

• The wrist cylinder is leaking.
• The wrist sensor may be intermittant.
