"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 21 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,
•
maximum speed (parameter RM)
•
The firmware of the connected e.sybox max units must all be the same.
Once the hydraulic system has been made, it is necessary to create the pumping set by carrying out the wireless association of
the devices (see par 8.5.5.)
11.1.3 Wireless communication
The devices communicate with each other and send the flow and pressure signals by wireless communication.
11.1.4 Connection and setting of the photo-coupled inputs
The inputs of the I/O control unit are used to activate the float, auxiliary setpoint, system disabling and low suction pressure functions. The
functions are indicated respectively by the float switch symbols (F1), Px, F3, F4. If activated, the Paux function boosts the pressure in the
