Statistical values, overload and non-standard condition The control unit stores: values, calibration values, list of features and condi- tions accessed *Can drop to 20V under load. Disturbing peak voltage generated by the lifting unit can be max. 60 V. The current peak when starting the motor can take up a maximum of 15A at 42V and it should drop to the maxi- mum value of permanent current consumption in 0.5s. -
