Reset
The height encoder can be easily reset to ground level (0.0) at any time.
To reset height select appropriate winch, then press and hold “UP” and “DOWN” buttons together. After a
few seconds hook height will reset to “0.0”.
Fault Finding
Function codes “View Uncalibrated Main Hook Height Input” (Main) and “View Uncalibrated Auxiliary Hook
Height Input” (Auxiliary) display uncalibrated data from the encoders. The displayed numbers should change
as the encoder rotates. This can be useful to ensure correct operation of the encoder and also for fault
finding.
Periodic System Testing
Hook height should be re-calibrated whenever boom length is changed.
Hook height should be reset whenever crane tower height is changed.
There is no periodic testing or re-calibration required.
