Direction Of Rotation; Switching On/Operation; Switch-On Types; Maintenance - Homa Sanipower Originalbetriebsanleitung

The faults described above are also indicated by an acous-
tic alarm device integrated in the controller.
The different signals have the following meanings:
• 1 beep/second = maximum runtime exceeded/motor
protection
• 3 beeps/second = high water alarm
The controller also has a test button at the top. This allows
the pump to be activated as a test, independently of the
level in the collection tank. This button can also be used
to activate emergency pump operation if the measuring
system fails or is faulty.
Central fault signal/mains-independent alarm (option)
As an option, the controller can be equipped with a fault
signal module (article number 1964159). The relay contact
can be operated with 5 A/230 VAC. The module is plugged
into the pin base provided for this purpose and secured
with the screws supplied. For the cable connection, install
the cable gland supplied if necessary.
If there is no fault, the relay picks up and contact 11/12 is
opened. In the event of a fault or power failure, the relay
drops out and contact 11/12 is closed.
An external on-site power supply is then required for sig-
nalling with a fault signal lamp.
If a mains-independent fault signal is required, operation
with the AL3 alarm control unit (see HOMA accessories)
with integral 9 V battery is also possible as an option. In-
stead of float switches, the potential-free contact of the
fault signal module can then be connected to the alarm
control unit. (Further described in the AL3 operating in-
structions.)

5.6. Direction of rotation

With single phase motors, it is not necessary to check
the direction of rotation, as they always run in the correct
direction.

5.7. Switching on/operation

To switch on, set the operating switch of the pump con-
troller to the „Auto" position.
As described in chapter 5.5.1, the pumps start to operate
as soon as the water level in the collection tank reaches
the required level. When the switch-off levels are reached,
the pump switches off automatically.

5.8. Switch-on types

Switch-on types with plug/switchgears
Insert the plug into the socket provided for and use the
on/off switch on the switchgear.

6. Maintenance

6.1. General

The entire system must be checked and serviced at reg-
ular intervals.
The following points should be noted:
• Only maintenance work and activities listed here may
be carried out.
• All maintenance, inspection and cleaning work on
the system must be carried out in a safe work space
with utmost care. The machine must be disconnect-
ed from the mains power supply for any work to be
carried out. An unintentional switching on must be
avoided.
• Electrical work on the machine and the system must
be performed by qualified personnel.
• In the event of flammable solvents and cleaning
agents being used, open fire, naked lights and
smoking is prohibited.
• Ensure that the necessary tools and materials are
available. Order and cleanliness guarantee safe and
trouble-free work on the machine. Remove used
cleaning materials and tools from the machine after
completing the work. Keep all materials and tools in
their designated places.
A trial run or functional test of the machine must only
be carried out under the general operating conditions!

6.2. Maintenance dates

Semi-annually:
• Visual inspection of the power supply cable
• Cleaning of the container

6.3. Maintenance work

Visual inspection of the power supply cable
The power supply cable must be examined for bubbles,
cracks, scratches, abrasions and / or pinching points.
Upon detection of damage, the damaged power supply
cord must be replaced immediately.
The cable may only be replaced by the manufactur-
er or an authorized or certified service workshop. The
machine may not be put into operation again until the
damage has been properly fixed!
Cleaning of the container
First, disconnect the container from the mains power
supply. Then remove the top by unscrewing the four
screws (under the covers in the corners) of the lifting
system. Thoroughly rinse the container with clean water.
Then close the container with the four screws.
