Reset Crane Data
Reset the systems crane data using the
‘Reset Crane Personality Data’
routine
in the calibration
‘Crane Data’
menu selection. This process uses some of the geometric data entered in the capacity
chip to prepare the system for calibration.
See the calibration manual for instructions on how to use the routine.
Zero Angle sensor
Mechanically zero the Boom Angle Sensor. Instructions for setting the potentiometer are contained within
the Extension Reel installation manual.
Double check that the boom has been set level prior to setting.
Set the angle sensor pot voltage to 1/10
th
of the drive voltage at the extension reel (0.5V nominal)
Zero Extension Sensor
Mechanically zero the Boom Extension Sensor. Instructions for setting the potentiometer are contained
within the Extension Reel installation manual.
Double check that the boom is fully retracted prior to setting.
Set the reeling Drum zero by measuring the drive voltage and adjusting the pot until the extension voltage
is equal to 1/20
th
of the drive voltage (0.25V nominal)
Span Angle Sensor
It is essential that the angle sensor is spanned as accurately as possible (preferably to within 0.1
degrees).
Boom up to at least 60 degrees and measure the boom angle with an inclinometer. Be careful to check
that a correct reading is obtained from the inclinometer.
Calibrate the angle span.
Before continuing, check the angle at an intermediate point such as 35 degrees and ensure that the
inclinometer and angle reading match within 0.2 degrees.
Span Extension Sensor
Fully extend the boom and calibrate the span of the extension sensor. It may be necessary to check the
actual extension by measuring with a tape. For this the boom may need to be flat to obtain a
measurement (If it is possible).
For extension sensors measuring intermediate lengths, the extension should be known before spanning
the sensor. It is always a good idea to check by taping with the boom flat if possible.
