5.6. Motor Protection
Single-phase motor
Pumps with 230 V/single-phase motor are equipped with
a control unit with a motor protection switch, capacitor
start and run capacitor. These HOMA switching devices
are also available as accessories. With other switching de-
vices, when configuring the motor protector switch, pay
attention to the rated current of the motor.
Three-phase motor
Pumps with three-phase motors have no standard switch-
gear with a motor protection switch. The matching
HOMA-switching devices are available as accessories.
5.7. Switch on Modes
Switch on modes with plug/switching devices
Insert the plug into the appropriate socket and press the
power button on the control unit.
Switch on modes with bare cables ends (without plug)
Switch on directly
With full load, the motor protection should be set to the
rated current. With part load operation, it is recommend-
ed to set the motor protection 5% at the operating point
above the measured current.
5.7.1. After Switch On
During start-up, the rated current is temporarily exceeded.
After completion of this operation, the operating current
should no longer exceed the rated current. If the motor
does not start immediately, it must be switched off at
once. Before switching it on again, all switching pauses
must be observed according to the specifications. If an-
other fault occurs, the machine must be shut down im-
mediately. Another switching may be started only after
troubleshooting.
The following points should be checked:
•
Operating voltage (permissible deviation +/- 5% of
rated voltage)
•
Frequency (permissible deviation -2% of the rated
frequency)
•
Power consumption (allowable deviation between
phases 5% max.)
•
Voltage difference between the individual phases
(max. 1%)
•
Switching frequency and pauses (see Specifications)
•
Minimum water coverage, level control, dry run
protection
•
Smooth running operation
•
Check for leaks, if the necessary, take necessary
steps according to Chapter „Maintenance".

6. Maintenance
6.1. General
The pump as well as the entire system must be inspec-
ted and maintained at regular intervals. The interval of
the maintenance is determined by the manufacturer and
applies for the general conditions of use. The manufac-
turer must be contacted in the event of aggressive and/
or abrasive pumped mediums, since the interval could be
shortened in these cases.
The following points must be noted:
•
The operating instructions must be available to the
maintenance personnel and must be followed. Only
maintenance work and measures listed here must be
carried out.
•
All maintenance work, inspection work and cleaning
work on the machinery and the system must be car-
ried out with due diligence, at a safe working place
and by trained qualified personnel. The required pro-
tective gear must be worn. The machinery must be
disconnected from the power supply for all work.
Unintentional start must be prevented. Furthermore
the respective protective measures according to the
Employers' Liability Association regulations, BGV/the
Statutory Accident insurance, GUV must be complied
with when working in basins and/or containers.
Ensure that sling gear, ropes and the safety equipment
of the hand winch are technically sound. The work
must only be started when the auxiliary hoisting gear
is technically in order. Failure to carry out these checks
may jeopardize your life!
•
easily inflammable dissolvers and cleaning materials
are used, open fire, open light as well as smoking are
prohibited.
•
Ensure that the required tools and materials are rea-
dily available. Tidiness and cleanness ensure safe and
proper work on the machinery. Remove used clea-
ning materials and tools from the machinery after
the work has been carried out. Keep all materials and
tools in a dedicated place.
•
Service media (such as for example oils, lubricants,
etc.) must be captured in a suitable container and
must be disposed of according to the regulation
75/439/EEC and writ §§5a, 5b abfG, Waste Avoidan-
ce and Management Act). Respective protective clo-
thing must be worn when carrying out cleaning work
and maintenance work. This must be disposed of ac-
cording to waste catalogue TA 524 02 and EC directi-
ve 91/689/EEC. Only lubricants recommended by the
manufacturer must be used. Oils and lubricants must
not be mixed. Only use manufacturer's original parts.
A test run or function test of the machinery must only
be carried out according to the general operating
conditions!
6.2. Maintenance schedule
Every six months:
•
Visual inspection of the power supply leads
•
Visual inspection of the cable holders and the wiring
