6.1.3. Operating principle

In automatic mode, the connected pump(s) are actuated depend-
ing on the fi ll levels defi ned. Measurement of the individual fi ll
levels can be performed via a fl oat switch or a level sensor:

"Empty" operating mode using the example of two pumps

pump OFF
• Level measurement via a fl oat switch
Up to fi ve fl oat switches can be connected to the switchgear:
• Base-load pump ON
• Peak-load pump ON
• Base-load and peak-load pump OFF
• Dry-running protection
• High water
This enables actuation of 1 or 2 pumps.
The fl oat switch should be equipped with an NO contact i.e. on
reaching or exceeding the switching point, the contact is closed.

"Empty" operating mode using the example of two pumps

* Also realised via a fl oat switch for increased operational reli-
ability.

• Level measurement via a level sensor
A level sensor can be connected to the switchgear, with which up
to 10 switching points can be defi ned:
• Base-load pump ON/OFF
• Peak-load pump 1 ON/OFF
• Peak-load pump 2 ON/OFF
• Peak-load pump 3 ON/OFF
• Dry-running protection
• High water
This enables actuation of 1 to 4 pumps.
On reaching the fi rst activation point, the base-load pump is
switched on. When the second activation point is reached, the
peak-load pump is cut-in after the set activation delay time has
elapsed. A visual indicator appears on the LC display and the green
LED lights up while the pump(s) is/are in operation.

On reaching the deactivation points, the base-load pump and
peak-load pump are switched off after the set stop delay and the
set follow-up time for the base-load pump have elapsed.
To optimise pump running times general pump cycling can take
place each time all pumps are switched off or periodical pump
cycling depending on a preset operation time can take place.
During operation, all safety functions are active. In case of one
pump malfunctioning, automatic changeover to a fully-functional
pump takes place. An optical alarm signal is output and the collec-
tive fault signal contact (SSM) is active.
Once dry run level or high water level is reached, a visual alarm
signal is output, the collective fault signal contact (SSM) and high
water alarm contact (only in case of overfl ow) are active. In addi-
tion forced switch-on or switch-off of all available pumps takes
place to increase operational reliability.
NOTE
In case of level measurement using a level sensor,
forced switch-on or switch-off only takes place if
dry-running protection and the high water alarm are
additionally realised with a fl oat switch!

Menu control and structure

6.2.1. Control
Fig. 6.: Operation
The menu is controlled via the operating knob:
• Turn: Selection and set values
• Press: Change menu level or confi rm value
6.2.2. Set-up
The menu is divided into two areas:
• Easy menu
For quick commissioning using the factory settings, only
the operating mode and the activation and deactivation
values need to be set here.
• Expert menu
For display and setting of all parameters.
Open menu
1. Press operating knob for 3 seconds.
2. Menu item 1.0.0.0 appears.
3. Turn operating knob to left: Easy menu
Turn operating knob to right: Expert menu
6.3.

Initial commissioning

NOTE
Observe the installation and operating instructions
for products provided onsite (fl oat switches, level
sensors, connected consumers) as well as the system
documentation!
