mers on the top of the housing.
The module switching threshold
level must be raised in case of dis-
turbances on the connection lines
between the module inputs and
the motor winding so that the
module is no longer sensitive to
the disturbances.
FAULT DIAGNOSIS
The list of possible safety module
faults or anomalous behaviour are
listed below along with the
respective solution (and it is by no
means exhaustive).
It is recommended to contact
Carlo Gavazzi service centre for
faults inside the safety module. In
case of any repairs carried out
inside the safety module by unau-
thorised personnel, Carlo Gavazzi
does not guarantee the correct
functioning of the safety module.
