DAB E.Box Plus Instructions Pour L'installation Et La Maintenance page 113

- Relay/remote control switch alarm
This error appears if the pump remote control switches have malfunctions. If this alarm occurs, check the wiring. If defects are found, the panel
must be repaired.
- Pump disconnected
This error appears if the E.Box panel does not "feel" current towards a pump. This error also appears if input KK (motor thermal protection) opens.
The alarm is specific for the pump. For each pump the alarm allows a series of restart attempts with a variable pause time between one start and
the next which is increased by 1 minute for the first 60 minutes (1-2-3 min.... 60 min.), after which there will be one attempt every hour.
To solve this error, check the pumps and the wiring and check the value of the set rated current (trimmer lmax).
- Dry running protection/alarm
When the pressure falls to a value of less than 0.5 bar for about 10 seconds, the alarm is activated with stopping of the pump and lighting of the
led. The dry running protection/alarm is activated in pressure boosting mode when an analog pressure sensor is connected.
This protection may be selected by the DS_A4.
After 1 minute there will be 1 reset attempt for maximum 30 seconds. If this attempt succeeds the alarm is reset, otherwise the pump will remain
in blocked status.
The dry running protection/alarm is not activated if the electropumps are started manually.
To solve the problem, check the hydraulic part of the plant. Check that everything is in order. Check also the pressure sensor and ensure the
pressure reading is regular.
- Protection against too frequent starts
This error appears when the system needs more than 8 starts per pump per minute; this normally occurs when there are leaks in the system or
the expansion vessel is deflated.
The protection against rapid starts allows each pump a maximum number of 8 starts per minute.
The protection does not intervene if the number of starts per minute is less than 8.
To solve the problem, check whether there are any leaks and check the expansion vessel if present.
- Current overload protection/alarm (overload protection)
This alarm appears in the event of a current overload on the pumps. The alarm is specific for the pump.
For each pump the current overload alarm allows 6 auto-reset attempts, every 10 minutes, in the space of 24 working hours. At the seventh
attempt the panel no longer makes auto-resets, unless after manual reset by the user. To solve this problem, check the pumps, the wiring, and
ensure the rated current of the pumps is set correctly. This error may be generated by a blocked pump.
- Pressure or depth sensor alarm
If operation with a 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.
- Floats and/or probes incoherence alarm
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.
- Dip-Switch alarm
The Dip Switch alarm is activated in the following cases:
Incoherence of the Dip Switch with the respective functions (incorrect configuration).
To reset the alarm:
Return the Dip Switches to the correct position.
•
Press the RESET key.
•
Dip Switch regulation with the panel live.
To reset the alarm, press the RESET key.
- Error alarm
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!
- Input voltage
If the alternating input voltage of the panel is not within the limits established in the specifications, the alarm is given for irregular alternating input
voltage. The alarm is deactivated one minute after the alternating input voltage returns within the limits. If this alarm occurs, check the panel input
voltage. If it is regular, the panel must be replaced.
