3.2.1 Control Outputs
Designed for fail-safe operation, the control outputs are wired to an external controller, drive or contact that
controls the trolley, bridge and hoist motions. The Fast Permissive will allow the bridge or trolley to run at
full speed when outside of the No-Fly Zone Slow Down Boundary. If the crane enters the Slow Down Zone
these relays would change state. The Forward/Reverse Permissive will allow the bridge or trolley to run
when outside of the No-Fly Zone Stop Boundary. If the crane enters the Stop Zone, these relays would
change state.
• Forward / Reverse Fast Permissive used to allow the bridge or trolley to run at full speed
• Forward / Reverse Permissive used to allow the bridge or trolley to run
• Hoist Lower Permissive output provides a control signal to an external controller or hoist drive
signaling that the crane and hoist are over the No-Fly Zone to prevent the hoist from lowering in the
No-Fly Zone (used for both hoist upper limit and machine down configurations)
• Clear of Machine Permissive output provides a control signal to an external controller or hoist drive
signaling that the crane and hoist is no longer above the machine
