English
The "Commissioning" section contains all the important instruc-
tions 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 per-
sonnel 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 understood 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 "In-
stallation" 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 specified
operating conditions.
7.1.

Level control

The float switches are installed according to the specifications for
the unit and the desired switching points have been set.
7.2.

Operation in potentially explosive areas

The switchgear may not be installed or used in potentially explo-
sive areas.
Connection of monitoring devices and signal transmitters used
within potentially explosive areas is strictly prohibited.
DANGER of explosions!
If the switchgear or the connected pump and signal
transmitter are used in potentially explosive areas,
there is a danger of fatal injuries from explosions!
The switchgear and connected pump and signal
transmitter must always be used outside of poten-
tially explosive areas.
7.3.

Activating the switchgear

POTENTIALLY fatal danger due to electrical voltage
All settings need to be made on the switchgear
components. When performing work on the un-
covered switchgear, there is a risk of fatal electric
shocks occurring. All work must be carried out by a
qualified electrician.
NOTE
Following a power supply interruption, the switch-
gear will automatically start up in the last operating
mode set!
The following points must be checked before activation:
• Check the installation.
• All terminals must be retightened.
• DIP switches 1 and 2 correctly set:
• Motor protection (DIP switch 1 DIP 1-5)
• Pump kick (DIP switch 1 DIP 6)
• Buzzer (DIP switch 1 DIP 7)
• Pumps activated (DIP switch 2, DIP 6 and 7)
• Follow-up time
If corrections are necessary, proceed as in the section "Electrical
connection".
1. Turn main switch to ON position.
2. All LEDs light up for 2 sec.
3. The switchgear is ready for operation.
• The "on" LED lights up constantly.
• The "auto" LED flashes: The switchgear is in stand-by
mode, automatic mode is off.
• The "auto" LED lights up: The switchgear is active, auto-
matic mode is on. To set the switchgear to stand-by mode,
press the Stop button.
NOTE
If an audible signal is sounded after activation and all
LEDs flash anti-clockwise in turn (in light sequence),
there is a phase fault 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 con-
necting the switchgear and the connected pumps.
7.4.1. Checking the direction of rotation
The rotation control of the connected pump can be performed
using a brief test run, max. 2 minutes.
1. Press the "Manual" button on the control panel for the
relevant pump.
2. The pump operates as long as the button is held down.
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
After activation, an audible signal sounds and all LEDs
flash in turn anti-clockwise:
The switchgear is incorrectly connected and the connected pump
is not operating correctly.
2 phases/conductors of the power supply on mains side to the
switchgear need to be swapped over.
Pump running incorrectly:
Connection of the switchgear is correct. Connection of the pump
is incorrect. 2 phases of the mains supply to the pump supply line
need to be swapped.
7.5.

Activating automatic mode on the unit

Before automatic mode is switched on, check the settings for the
switching level and follow-up time.
