LMI Setup-Greer EEC-0066 V1.0
LMI Setup
You will use the Greer Insight system to aid in the crane’s operation. Please
ensure only an operator properly trained in safety procedures, crane manufacturer’s
specifications and the crane’s capacity information operates this unit. There are several
operation functions to be aware of when using this unit:
Boom Angle Sensor: The crane uses a sensor connected to a potentiometer or
pendulum assembly to measure the boom angle. The sensor is mounted within
the cable reeling drum’s assembly.
Extension Sensor: This sensor is mounted inside the cable reeling drum
assembly, and measures the extension of the boom arm.
Pressure Sensors: Two sensors measure the boom hoist cylinder’s pressure;
one sensor measures pressure on the cylinder rod, and the other sensor
measures pressure on the piston.
Anti-Two-Block switch: The ATB switch monitors the hookblock/overhaul ball
on its approach to the boom head. The switch remains closed until the
hookblock/overhaul ball raises a weight that connects to the hoist rope, which
opens the switch. Once open, the switch sends a signal to the LMI computer,
which triggers the ATB alarm, followed by a function kick-out.
Function Kick-Out: A function kick-out uses hydraulic solenoids to disconnect
the control lever functions for boom hoist lowering, telescoping out, and winch up
once the ATB alarm activates.
Operator Programmable Alarms: The operator uses these alarms to set the
crane’s minimum and maximum angle, maximum height, and maximum length.
Work Area Alarm: This alarm allows the operator to define the crane’s operating
zone by only using two set points.
Swing Sensor: The swing sensor measures the rotation angle of the boom as it
relates to the crane chassis. NOTE: This feature is not used on all models.
