7.1.3 Hall unit assembly/disassembly
The Hall unit is an ESD sensitive device. Before connecting the
Hall unit, take appropriate measures for ESD protection (ESD =
electrostatic discharge).
If a Hall unit on the primary part must be retrofitted or exchanged, remove a
dummy or the Hall unit to be changed from the installation space of the sen‐
sor. For easy press out of the dummy or the Hall unit, a small tool is provided
with the accessory delivery. The existing fastening screws can be used for
assembly of the new Hall unit. Observe the allowed tightening torque (see
Fig. 7-1 ) not to be exceeded, when tightening the fastening screws. A too
high tightening torque can damage the fastening thread of the Hall unit and
can make it useless, then.
Fig. 7-3: Hall unit assembly / disassembly
1. Loosen both fastening screws. Store them until the new Hall unit must
be fastened. When loosing the fastening screws, only use screws of the
same design (see Fig. 7-1 )!
2. Press the dummy or the Hall unit with the tool out of the installation
space and remove it.
3. Assemble the new Hall unit.
