- HL: Maximum level alarm

This error comes from the depth sensor, when its indication exceeds the threshold ML (Maximum Level). This can
happen when the depth sensor is used for the maximum and minimum level alarms. The solution of the problem
always consists of checking the set thresholds, the level of liquid in the tank and the sensor status. The panel
behaviour is different depending on the operative mode. In drainage this error causes the forced start of the pumps
and in filling the forced stop of the pumps.

- LL: Minimum level alarm

This error comes from the depth sensor, when its indication is below the threshold LOL (Minimum Level). This can
happen when the depth sensor is used for the maximum and minimum level alarms. The solution of the problem
always consists of checking the set thresholds, the level of liquid in the tank and the sensor status. The panel
behaviour is different depending on the operative mode. In filling this error causes the forced start of the pumps and in
drainage the forced stop of the pumps.

- BP1/BP2: Pressure sensor / depth sensor alarm

If operation with a pressure or depth sensor is selected, but the panel does not detect the sensor, the pumps are
deactivated and an alarm is indicated. In this case check the wiring.
If the sensor has been correctly installed, but the sensor signal is outside the measuring range, the pumps are
deactivated and an alarm is indicated. Check the pressure in the plant and, if the sensor reading is not correct, change
the sensor.

- FI: Floats or level probes state incoherence

This error occurs when the state of the floats or of the level probes is not correct, for example the float on the highest
level of the tank indicates the presence of water and the lower floats do not. To solve these problems, check the wiring
and the state of the floats. It is possible to see the position detected by the panel on the display. It is recommended to
check that there are no holes in the floats.

- DS: Dip Switch alarm

The Dip Switch alarm appears if the positions of the dip switches have been changed.
If the new configuration of the dip switches is valid, you are asked whether to accept it or ignore it. If it is accepted, the
E.Box will start to work with the new configuration. If the new configuration is not valid, it is proposed that you ignore
it.

- W1: Trimmer SP

This error appears if the trimmer SP inside the panel has been moved. You are asked whether to accept or ignore the
new value of SP. If it is accepted, the value of the dip switches will also be accepted.

- W2: Trimmer DP

This error appears if the trimmer DP inside the panel has been moved. You are asked whether to accept or ignore the
new value of DP. If it is accepted, the value of the dip switches will also be accepted.

- W3: Trimmer Imax

This error appears if the trimmer Imax inside the panel has been moved. You are asked whether to accept or ignore
the new value of Imax. If it is accepted, the value of the dip switches will also be accepted.
ENGLISH
This error appears in pressure boosting and indicates that the maximum
pressure switch is activated or that the contact N has not been jumpered.
The E.Box stops. In KIWA pressure boosting the error is not self-resetting
and manual intervention is necessary.
This error appears in filling and indicates that the minimum level float is
activated or that the contact N has not been jumpered. The E.Box stops the
pumps.
This error appears in drainage and indicates that the minimum level float is
activated or that the contact N has not been jumpered. The E.Box stops the
pumps.
This error appears in drainage and indicates that the level probe for
minimum level is activated or that the contact N has not been jumpered. The
E.Box stops the pumps.
This error appears in filling and indicates that the level probe for maximum
level is activated or that the contact N has been jumpered. The E.Box
activates the pumps.
