Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product.
‐Make sure that the power supply
cannot be switched on accidentally.
‐We recommend that you unplug the
control box from the socket.
If the potential-free alarm contact is to be
used to forward the alarm signal to a main
controller, connect the signal cable to
terminal block X2, terminals 3 and 4.
If the filling function is to be used instead
of the emptying function, move the lead
from terminal X1-1 to terminal X1-2.
7. Startup
Trim the electrodes to the desired length in
advance, depending on the pump. Take
into account the technically feasible
switching levels of the pump.
After installation, plug the control box into a socket
and plug the pump plug into the control box socket.
Carry out test runs. To do so, press and hold the
switch on the control box. The level controller will not
operate when the switch is actuated. The pump runs
for as long as the button is held.
If you encounter faults during test operation, verify
that the power supply is correct, that the connected
units function properly, and that the liquid has
sufficient conductivity. See section Fault finding for
more details.
If the switch on the control box is not pressed, the
level controller operates automatically.
Change over from the emptying function (delivery
state) to the filling function is described in section
Electrical connection.
8. Operation
Once the level controller has been installed and
started up, no further action is required.
The level controller operates automatically and
switches the connected wastewater pumps on and off
based on the liquid level.
For a trial run or to briefly switch the pump on and off
during commissioning or service work, the pump can
be manually operated by pushing the switch on the
control box. See also section Startup.
