Lockout relay inversion. By default the lockout wires carry crane power supply voltage
as long as the display is in safe condition. When lockout is triggered voltage is cut on the
lockout wires linked to the lockout condition.
Warning! Inverting lockout relays will allow crane operation in the event the GS550
display fails. Operating a crane without a functioning anti-two-block system and load
and angle indication is dangerous and may be against the law.
Exceptionally the lockout relay can be inverted so that lockout wires carry no voltage in safe
condition and carry crane power supply voltage when in a triggered lockout condition. In
this case if the display fails, crane functions will not lockout.
