10.2 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.

10.3 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
"OC" Blockage due to motor overload
"BP" Blockage due to fault of the pressure sensor
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.

11. PARTICULAR INSTALLATIONS

11.1 Multiple Sets

11.1.1 Introduction to multipump systems
By multipump systems we mean a pump set made up of a number of pumps whose deliveries all flow into a common manifold.
The devices communicate with one another by means of the connection provided (wireless).
The group may be made up of a maximum of 4 devices.
A multipump system is used mainly for:
Increasing hydraulic performance in comparison with a single device.
•
Ensuring continuity of operation in the event of a device developing a fault.
•
Sharing out the maximum power.
•
11.1.2 Making a multipump system
The hydraulic plant must be created as symmetrically as possible to obtain a hydraulic load uniformly distributed over all the pumps.
The pumps must all be connected to a single delivery manifold.
For good operation of the pressure boosting set, the following must be the same for each device:
hydraulic connections,
