- 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.
- PK: Key error
If pressing of the buttons on the front board is detected in the first 30 seconds of power supply, the buttons incoherence alarm is activated.
Check that the buttons function efficiently!

- NL: Input voltage error

If the alternating input voltage of the panel is not within the limits established in the specifications, the input voltage alarm is given. The alarm is
deactivated one minute after the alternating input voltage returns within the limits. If this error appears, check that the supply voltage is within
the limits accepted by the E.Box panel, see table 1 - Technical Data.

- VS: Voltage selector error

This error may occur on the E.Box plus, in the case of a fault of the E.Box Plus or breakage of the fuse FU2. In the case of an alarm, check the
fuse FU2 and ensure the panel is supplied with an adequate voltage, as specified in Table 1 – Technical Data.
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.
