Description Of Blockages; Bl" Anti Dry-Run (Protection Against Dry Running); Anti-Cycling (Protection Against Continuous Cycles Without Utility Request) - DAB E.SYBOX MINI 3 Instrucciones Para La Instalación Y El Mantenimiento

In the case of blockage due to water lack (BL), blockage due to motor over-
load (OC), blockage due to direct short circuit between the motor phases
(SC), you can try to exit the error conditions manually by simultaneously
pressing and releasing the + and – keys. If the error condition remains, you
must take steps to eliminate the cause of the fault.
In the event of blocking due to one of the internal errors E18, E19, E20,
E21 it is necessary to wait 15 minutes with the machine powered until the
blocked status is automatically reset.

6.1 - Description of blockages

6.1.1 - "BL" Anti Dry-Run (Protection against dry running)

In the case of lack of water the pump is stopped automatically after the
time TB. This is indicated by the red "Alarm" led and by the letters "BL" on
the display.
After having restored the correct flow of water you can try to leave the
protective block manually by pressing the "+" and "-" keys simultaneously
and then releasing them.
If the alarm status remains, or if the user does not intervene by restoring
the flow of water and resetting the pump, the automatic restart will try to
restart the pump.
If the parameter SP is not correctly set, the protection against
water lack may not work correctly.
6.1.2 - Anti-Cycling (Protection against continuous cycles without
utility request)
If there are leaks in the delivery section of the plant, the system starts and
stops cyclically even if no water is intentionally being drawn: even just a
slight leak (a few ml) can cause a fall in pressure which in turn starts the
electropump.
The electronic control of the system is able to detect the presence of the
leak, based on its recurrence.
The Anti-Cycling function can be excluded or activated in Basic or Smart
mode (par 5.6.6).
