While the overload control indicator is integrated with the Load Cell product, it provides easy connection to industrial control devices.It is a robust and high quality control unit designed to be used in cranes with 8 relay outputs.With double cat / double hook cranes, it can measure the weight and total weight of the load attached to each hook separately.
ISSUES TO BE CONSIDERED BEFORE CALIBRATION
Be sure that you have already connected 4 different cables at the loadcell to the control unit subject to their colors
After connecting supply voltage and LoadCell duly then any value is seen on load control screen. As far as tensioning at crane rope then there should be increasing value. Otherwise no calibration is applied, in this case, standard factory settings of load control unit should be downloaded and re-test should be applied.
Before applying calibration, rope should not be descended and shouldn’t be keep at position without load and it should be waited until motionless.
