When telescopic beam hinge pin switch is moved and held in
engage (in) position, an input signal from wireless
transmitter is sent to a receiver on the crane. The receiver
sends the input signal to Node-1 controller. Node-7 sends a
24 volt output to enable telescopic beam hinge pins solenoid
HS-90 and shifts valve to the engage position. Node-3
controller sends a variable zero to 24 volt output to enable
accessory system proportional relief solenoid HS-68 for a
system pressure of 400 psi (28 bar) to hinge pin cylinders.
Hydraulic fluid pressure at approximately 400 psi (28 bar)
flows to beam hinge pin accessory valve. Hydraulic fluid
leaves the accessory valve and enters piston end of beam
pin cylinder, extending cylinder rod to engage beam hinge
pins. Hydraulic fluid from rod end of beam pin cylinder leaves
accessory system valve and returns to tank.
When beam hinge pins switch is released, an input signal is
sent to Node-1 controller. Node-7 controller sends a zero volt
output to hydraulic solenoid HS-90 to return valve to center
position.
Node-3 sends a variable voltage output to accessory system
proportional relief solenoid HS-68 to provide approximately
3,000 psi (207 bar) system pressure.
Install locking pins in engaged position.
