is accomplished by use of the check valves installed on both cylinders. By holding the
STROKE CHANGE switch, you have interrupted the cycle and are forcing more oil into
the head side of the extending cylinder. Since that cavity is full, pressure is built up in the
rod side of the fully retracted cylinder, which unseats the head-side check valve and
forces the excess oil out of the slave loop and back to the tank. Once the extending
cylinder has reached its full stroke, regular operation can continue.
Short stroking can also occur from incorrect proximity sensor location or leaking check
valves.
