• The stator incorporates three thermal contacts connected in series that activate the
alarm and stops the pump at overtemperature
• The thermal contacts open at 125°C (257°F) or 140°C (284°F). For more information,
see Technical Reference on page 58.
• Ex-approved pumps must have thermal contacts connected to the control panel.
• The sensors must be connected to either the MiniCAS II monitoring equipment or an
equivalent equipment.
• The monitoring equipment must be of a design that makes automatic restart
impossible.
Optional sensors
FLS FLS is a miniature float switch for detection of liquid in the stator housing. Due to its
design it is best suited for pumps in a vertical position. The FLS sensor is installed in
the bottom of the stator housing.
