The operation and maintenance manual must always be
kept with the machinery, or in a dedicated place where it
is accessible for the entire operating personnel.
The following points must be taken into account to avoid
personal and material damage when troubleshooting ma-
chinery failures:
The commissioning of the machinery must only be
carried out by qualified and trained personnel in com-
pliance with the safety regulations.
•
All personnel that is working on the machinery must
have received, read and understood the operating in-
structions.
•
Activate all safety equipment and emergency switch-
offs before commissioning.
•
Electrotechnical and mechanical settings must only
be carried out by specialists.
•
This machinery is only suitable for the use under the
indicated operating conditions.
5.5. Preparation work
The machinery was constructed and fitted according to
the latest technology, so that it works for a long time and
reliably under normal operating conditions. This requires
however that you comply with all requirements and in-
formation. Small oil leakages of the floating ring seals on
delivery are not problematic, but they must be removed
before lowering/immersion into the medium.
Please check the following points:
•
Cable run - no loops, slightly tightened
•
Check temperature of the medium and submersion
depth - see machinery data sheet
•
If a tube is used for pressure, this must be rinsed with
clear water so that no deposits lead to obstruction.
•
The pump pit must be cleaned for wet installation
•
The pressure-sided and suction-sided pipework sys-
tem must be cleaned and all gate valves must be
opened
•
The pump casing must be flooded, e.g. it must be
filled completely with the medium and it must not
contain an air. The de-aeration can be carried out by
means of suitable venting devices in the system or, if
available, by air-vent screws on the pressure socket.
•
Check accessories, pipework, suspension devices for
firm and correct fitting
•
Check available level controls/protection against dry
run
5.6. Electrical system
The respective local and VDE regulations must be com-
plied with when choosing and installing the electrical
leads as well as connecting the motor. The motor must be
protected with a circuit breaker.
Electric shock hazard!
Faulty dealing with current may jeopardize your life! All pumps
with free cable ends must be connected by a qualified electri-
cian.
5.7. Direction of rotation
For 1Ph-motors, control of the direction of rotation is not
necessary as these always run in the correct direction of
rotation.
The stated specifications and performance can only
be achieved if there is a clockwise rotating field. The
machine is not designed for use on a left rotating field.
5.8. Motor protection
The minimal requirement is thermal relay / circuit break-
er with temperature compensation, differential trigger
and anti-pumping device in accordance with VDE 0660/
respective local regulations. If the machinery is connect-
ed to electric circuits in which frequent interferences oc-
cur, we recommend additional installation of safeguarding
equipment (e. g. overvoltage relay, under voltage relay or
phase failure relay, lightning protection, etc.). The local and
legal regulations must be complied with when connecting
the machinery.
5.9. Start-up methods
Start-up with plug
Plug the connector into the socket provided and press the
on/off switch on the switching device.
5.9.1. After turning on
The nominal current is briefly exceeded on start-up. After
completion of this operation, the operating current should
not exceed the nominal current. If the motor does not start
immediately after switching on, it must be shut down im-
mediately. The switch breaks according to the technical
data must be adhered to before turning on again. If there
is a new fault, the machine must again be shut down im-
mediately. The machine may be powered-on again only
after troubleshooting.
The following items should be checked:
•
Operating voltage (permissible deviation +/- 5% of
the rated voltage)
•
Frequency (permissible deviation -2% of the rated fre-
quency)
•
Current consumption (permissible deviation between
phases max. 5%)
•
Voltage difference between the individual phases
(max. 1%)
•
Switching frequency and pauses (see Technical Data)
•
Air entry at the intake - if necessary, a baffle plate
must be attached
•
Minimum water coverage, level control, dry run pro-
tection
•
Smooth running
•
Check for leaks: if necessary, take the necessary
steps according to the chapter „ Maintenance"
