7. Commissioning
POTENTIALLY fatal danger due to electrical
voltage!
Incorrect electrical connections can cause fa-
tal electric shocks! Electrical connections may
only be inspected by a qualified electrician
approved by the local energy supply company,
in accordance with locally applicable regula-
tions.
The "Commissioning" section contains all the
important instructions for operating personnel
on commissioning and operating the switchgear
safely.
Always keep this manual either by the switchgear
or in a place specially reserved for it, where it is
accessible for all operating personnel at all times.
All persons working on or with the switchgear
must have been provided with this operating and
maintenance manual and have read and under-
stood it.
In order to prevent damage or serious injury when
commissioning the switchgear, the following
points must always be observed:
• The switchgear must be installed as described in
the "Installation" section and in accordance with
the applicable national regulations.
• The switchgear must be properly fused and
grounded.
• All unit safety devices and emergency cut-outs
must be connected and inspected to ensure that
they are working properly.
• The switchgear is suitable for use under the spec-
ified operating conditions.
7.1. Level control
The signal transmitters are installed according to
the unit specifications and the desired switching
points set.
When using a level sensor, the switching points
were set via the menu.
7.2. Operation in potentially explosive areas
The switchgear may not be installed or used in
potentially explosive areas.
Monitoring devices and signal transmitters used
within potentially explosive areas must only be
connected to the Ex variant of the switchgear
(SC-L...-Ex).
RISK of fatal injury due to explosive atmos-
phere!
The switchgear is not Ex-rated. Operation
in potentially explosive areas will lead to
explosions! The switchgear must always be
installed outside potentially explosive areas!
7.3. Activating the switchgear
NOTE
Following a power supply interruption, the
switchgear will automatically start up in the last
operating mode set!

1.
Turn main switch to ON position.
2.
All LEDs light up for 2 s and the current operat-
ing data and the standby icon appear on the LC
display.
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-run-
ning 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.
7.4. 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 connecting 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 min-
utes. Thereafter the pump will switch off auto-
matically 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
conditions. For this, observe the installation
and operating instructions for the pump and
ensure that the required operating conditions
are complied with.
