Direct on line start
If persons are likely to come into
physical contact with the machine
or mixed/pumped media (liquid),
e.g. on farms etc, the earthed
(grounded) socket must have an additional
earth-(ground-) fault protection
device (GFI) connected.
When mixing/pumping near a lake (jetties,
beaches and ponds etc) a safety distance of at
least 20 meters (65 ft) between the person and
the machine is necessary. The machine must
never be placed directly into a swimming pool.
If used in connection with swimming pools,
special safety regulations apply.
Monitoring equipment
Make sure that the monitoring
equipment incorporated in the
product is correctly connected.
Capacitive leakage sensor CLS-30 and
leakage sensor FLS (built in version).
The machine is available with leakage sensors for
sensing water in the oil and/or the stator casing.
A plate in the junction box shows that the machine is
equipped with sensors.
CLS-30 is a leakage sensor for sensing water in the oil
casing and issues an alarm when the oil contains 30%
water. Oil change is recommended within 14 days of
alarm. If the sensor issues an alarm shortly after the oil
is changed, contact your nearest Flygt representative.
The CLS-30 sensor is installed in the bearing housing
and goes down into the oil casing. Available for 4650
to 4680. The CLS-30 sensor is not applicable to Ex-
approved machines.
Observe that the CLS cover is
made of glass and can cause
personal damage.
The FLS sensor consists of a small float switch for
sensing water in the stator casing.
The FLS sensor is installed in the bottom of the stator
casing.
The two sensors, CLS-30 and FLS, can be used in the
same machine. They are connected in parallel. Follow
the instruction for monitoring equipment.
