Replacing the leader motor safety PCB
Before removing the leader Motor Safety PCB it is impor-
tant to upload hoist data on to your computer or note
book. This will be done through the Guldmann service
console. The data is to be saved and loaded on to the
replacement PCB. (Follow the instructions in the SIC Tech-
nicians Manual).
After data has been uploaded disconnect batteries see
page 27. And remove bottom cover by laying hoist on
top cover see page 36.
Disconnect any wires from the PCB remembering were
they are connected. Taking a photo before unplugging
wires is a good way to record this, also see wiring dia-
grams at back of manual.
