Upper and lower limit switches (Configuration B)
Check the condition of the rubber pad on top of the hook and also
on the other end of the chain, at the chain bag. The plastic rings
activate the upper and lower limit switches on the hoist. If a plastic
ring is broken then it is a sign that a limit switch is not functioning
correctly.
Check for correct operation of the limit switches by raising and
lowering the hook at low speed until the limit switches are
activated and prevent further upward or downward movement.
