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
devices, when configuring the motor protector switch, pay attention to the rated current of the motor.
5.7. Switch on types
Switch on modes with plug
Insert the plug into the intended outlet.
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 another
fault occurs, the machine must be shut down immediately. A new 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

6. Maintenance

6.1. General

The pump as well as the entire system must be inspected and maintained at regular intervals. The interval of the
maintenance is determined by the manufacturer and applies for the general conditions of use. The manufacturer
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
carried out with due diligence, at a safe working place and by trained qualified personnel. The
required protective 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!

If 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 readily available. Tidiness and cleanness ensure
safe and proper work on the machinery. Remove used cleaning 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
Avoidance and Management Act). Respective protective clothing must be worn when carrying out
cleaning work and maintenance work. This must be disposed of according to waste catalogue TA
524 02 and EC directive 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!
