Check the following operating parameters:
• Operating mode: "empty" or "fill" (Menu 1.1.0.0)
• Selection of signal transmitter: "Floater" or "Sensor"
(menu 5.2.6.0)
• Threshold values for activation/deactivation level when
using a level sensor (menu 1.2.2.0)
• Installation and switching points when using float
switches
• Start and stop delay (menu 1.2.5.0)
• Limit values for high water and dry-running protection
when using a level sensor (menu 5.4.0.0)
• Pumps are enabled: AUTO (menu 3.2.1.0)
If corrections are necessary, proceed as in the section "Operation".
3. The switchgear is now ready for operation.
NOTE
If the error code "E06" appears on the display after
activation, a phase error is present in the mains
connection. Follow the instructions under "Rotation
control" for this.

Rotation control of connected three-phase AC motors

In the factory, a switchgear for a clockwise rotating field is
checked for correct direction of rotation and set.
Observe the wire designations on the wiring diagram when con-
necting the switchgear and the connected pumps.
7.4.1. Checking the direction of rotation
Rotation of the connected pumps can be checked using a brief
test run of max. 2 minutes. To do this, manual mode needs to be
started for each pump via the menu.
1. Select the relevant menu item for the appropriate pump:
• Pump 1: 3.2.1.1
• Pump 2: 3.2.2.1
• Pump 3: 3.2.3.1
• Pump 4: 3.2.4.1
2. Select "HAND"
3. The connected pump will run for a max. 2 minutes. There-
after the pump will switch off automatically and "OFF" will
appear.
4. If the direction of rotation is correct and the pump is to be
used for automatic mode, select "AUTO".
BEWARE of damage to the pump
A test run of the connected pump should only be
performed under the permissible operating condi-
tions. For this, observe the installation and operat-
ing instructions for the pump and ensure that the
required operating conditions are complied with.
7.4.2. If the direction of rotation is not correct
The fault code "E06" (rotating field error) will appear on
the display.
The switchgear is incorrectly connected and all connected pumps
are operating incorrectly.
2 phases/conductors of the power supply on mains side to the
switchgear need to be swapped over.
Pump is operating incorrectly (without error code E06):
Connection of the switchgear is correct. Connection of the pump
is incorrect.
• In case of motors with direct starting, 2 phases of the
pump supply line must be swapped over.
• With star delta activation motors, the connections of two
windings need to swapped over, e.g. U1 with V1 and U2
with V2.

Automatic mode on the unit

NOTE
Observe the installation and operating instructions
for products provided onsite (float switches, level
sensors, connected consumers) as well as the system
documentation!
7.5.1. Activating automatic mode on the unit
If all settings have been checked, you can switch the unit on using
menu item 3.1.0.0.
1. Select menu item 3.1.0.0.
2. Select "ON"
3. The unit now runs in automatic mode. As soon as the
signal transmitters supply a corresponding signal, the
relevant pumps are activated
7.5.2. Conduct during operation
When operating the switchgear, always follow the locally applica-
ble laws and regulations for work safety, accident prevention and
handling electrical products.
To help to ensure safe working practice, the responsibilities of
employees should be clearly set out by the operator. All personnel
are responsible for ensuring that regulations are observed.
Check the settings at regular intervals as to whether they meet
the current requirements. The settings may need to be adjusted.
7.6.

Emergency operation

POTENTIALLY fatal danger due to electrical voltage
To operate the separate main switches for each
pump by hand, the cover must be opened. There
is a risk of fatal injury due to live parts! This work
may only be carried out by a qualified electrician.
In case of a control failing, the individual pumps can be switched
on manually.
In such cases, each connected pump can be activated separately
via the relevant HAND-0-AUTO switch on the switchgear.
• Switch-on: Set the switch to "HAND (H)".
• Switch off: Set the switch to "0 (OFF)".
• For automatic mode, the switches need to be reset to
"AUTO (A)".
If the connected pump is switched on via the sepa-
rate HAND-0-AUTO switch in the switchgear, this
will run constantly. No regulation will take place via
the control. Make sure that the permissible usage
conditions for the pump are observed accordingly!
