7.1. Level control
The signal transmitter is installed according to
the unit specifications and the desired switching
points are set via the menu.
7.2. Operation in potentially explosive areas
• The switchgear may not be installed or used in
potentially explosive areas.
• Pumps may not be connected within an explosive
atmosphere.
• Connection of the level sensor is made using an
intrinsically safe electric circuit. Consequently, the
level sensor can be installed within an explosive
atmosphere.
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 operating
data and the standby icon appear on the LC dis-
play.
Check the following operating parameters:
• Threshold values for activation/deactivation
level (menu 1.2.2.0)
• Start and stop delay (menu 1.2.5.0)
• Limit values for high water and dry-running
protection (menu 5.4.0.0)
• Pumps are enabled: Operating mode switch on
the switch cabinet front is at "AUTO"
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.
38
7.4.1. Checking the direction of rotation
The rotation control of the connected pump can
be performed using a brief test run. To do this,
manual mode needs to be started for each pump.
1.
Set the operating mode switch of the required
pump to "HAND".
2.
The pump operates until you set the operating
mode switch back to "0" (OFF).
3.
If the direction of rotation is correct and the
pump should be used for automatic mode, set the
operating mode switch to "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.
7.4.2. If the direction of rotation is incorrect
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. Connec-
tion 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 connec-
tions of two windings need to swapped over, e.g.
U1 with V1 and U2 with V2.
7.5. Automatic mode on the unit
NOTE
Observe the installation and operating in-
structions for products provided on-site (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 applicable laws and regulations for work
safety, accident prevention and handling electri-
cal products.
To help ensure safe working practice, the respon-
sibilities of employees should be clearly specified
