This parameter keeps track of how often the firmware detects a leaking wrist cylinder. If the
wrist times out moving out, then the plate is released. If, even without the plate, the wrist
still doesn't move out in time, then this counter is incremented. The firmware then moves the picker
head out, then back in to try and reseal the wrist solenoid (when the head is in the out position,
the fixed orifice that controls the speed of the wrist out motion is bypassed. This high/fast flow
causes the cylinder to re-seal).
The firmware then tries again to grab the plate. If the wrist times out again moving out, then
this parameter is incremented a second time, and the device suspends with an error message indicating
a faulty wrist cylinder.
This parameter is updated automatically when an error occurs. It should not be changed.
It is possible for this counter to be incremented without a suspend error ever being reported to the
operator. This counter is often an indicator of potential picking problems that can be fixed before
they become an inconvenience to the customer
