Bp1" Blockage Due To Fault Of The Delivery Pressure Sensor (System Pressurisation); Bp2" Blockage Due To Fault Of The Suction Pressure Sensor; Pb" Blockage Due To Supply Voltage Outside Specifications; Sc" Blockage Due To Short Circuit Between The Motor Phases - DAB esybox mini3 Installations- Und Wartungsanleitungen

The Anti-Freeze protection works only if the system is regularly fed: with the plug disconnected or in the absence of current the
protection cannot work.
However, it is advised not to leave the system full during long periods of inactivity: drain the system accurately through the drainage cap and put
it away in a sheltered place.

6.1.4 - "BP1" Blockage due to fault of the delivery pressure sensor (system pressurisation)

If the device detects a fault in the delivery pressure sensor the pump remains blocked and the error signal "BP1" is given. This status begins as
soon as the problem is detected and ends automatically when correct conditions have been restored.

6.1.5 - "BP2" Blockage due to fault of the suction pressure sensor

If the device detects a fault in the suction pressure sensor the pump remains blocked and the error signal "BP2" is given. This status begins as
soon as the problem is detected and ends automatically when correct conditions have been restored.

6.1.6 - "PB" Blockage due to supply voltage outside specifications

This occurs when the allowed line voltage at the supply terminal assumes values outside the specifications. It is reset only automatically when the
voltage at the terminal returns within the allowed values.

6.1.7 - "SC" Blockage due to short circuit between the motor phases

The device is provided with protection against the direct short circuit which may occur between the motor phases. When this blockage is indicated
you can attempt to restore operation by simultaneously holding down the ˄ and ˅ keys, but this will not have any effect until 10 seconds have
passed since the moment the short circuit occurred.

6.2 - Manual reset of error conditions

In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the ˄ and ˅ keys.

6.3 - Self-reset of error conditions

For some malfunctions and blockage conditions, the system attempts automatic self-reset.
The auto self-reset procedure concerns in particular:
"BL" Blockage due to water lack
"PB" Blockage due to line voltage outside specifications
"OT" Blockage due to overheating of the power stages
For example, if the system is blocked due to water lack, the device automatically starts a test procedure to check whether the machine is really
left definitively and permanently dry. If during the sequence of operations an attempted reset is successful (for example, the water comes back),
the procedure is interrupted and normal operation is resumed.
Table 13 shows the sequences of the operations performed by the device for the different types of blockage..
