Note: Before replacement can be done, the data stored on
the PCB must be down loaded on to the, Guldmann ser-
vice console . See how to do this in the SIC manual .
After data has been loaded on to service console it is safe
to replace the Motor safety PCB, pull the emergency cord
to turn the hoist off, and remove the bottom cover .
Note: It is important to always use a antistatic mat and
wrist band when working inside the hoist .
Disconnect the battery wires as described on page 74 .
Disconnect all wires from PCB remembering were they are
connected to . Taking a photo is a good way of recording
this .
Now remove the PCB from the plastic housing . Replace
with new PCB and reconnect wires leaving battery wires
until last .
Note:
It is important to register all PCB exchanges on the
Guldmann traceability web site.
Before hoist can be put back into service the PCB needs to
be be configured by using the data taken off the old PCB,
