6. Startup
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
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
7. 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
.
8. Taking the product out of operation
1. Disconnect the control box from the power
supply, for instance by unplugging the control box
from the socket.
2. Unplug the pump from the pump control box, or
remove the cables from the terminals in the event
of direct connection to the pump.
3. Remove the electrode bracket from the pump.
4. Carefully wash the electrodes with clean water.
9. Maintenance
The level controller is maintenance-free. However,
the electrode tips must be cleaned at regular
intervals to remove any deposits that could
otherwise lead to malfunctions. The maintenance
intervals to be observed depend on the operating
conditions and the liquid pumped.
Note
Trim the electrodes to the desired length in
advance, depending on the pump. Take
into account the technically feasible
switching levels of the pump.
Warning
Before starting work on the product, switch
off the power supply. Make sure that the
power supply cannot be accidentally
switched on. We recommend that you
unplug the control box from the socket.
