13.3.9. 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
“BP1” Blockage due to fault of the pressure sensor
“BP2” Blockage due to fault of the Kiwa 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.

Description
Automatic reset sequence
BL Blockage due to water lack
- One attempt every 10 minutes for a total of 6 attempts.
- One attempt every hour for a total of 24 attempts
- One attempt every 24 hours for a total of 30 attempts
PB
Blockage due to line voltage outside
specifications
- It is reset when it returns to a specific voltage.
OT
Blockage due to overheating of the
power stages
- It is reset when the temperature of the power stages returns
within the specifications.
OC Blockage due to motor overload
- One attempt every 10 minutes for a total of 6 attempts.
- One attempt every hour for a total of 24 attempts.
- One attempt every 24 hours for a total of 30 attempts.

13.4. Operation with control unit
The pump, alone or in a pumping unit, can be connected via radio communication to an external unit hereinafter referred to as the control
unit. Depending on the model, the control unit offers various functions.
Possible control units are:
• Esy I/O
The combination of one or more pumps with a control unit allows you to use:
• Digital Inputs
• Relay outputs
• Remote Pressure Sensor
• Modbus communication protocol
In the following, we will indicate with the term control unit functionality, the set of functions listed above and made available by the
various types of control unit
13.4.1. Functionality available from the control box
The available features are listed in the table below.

13.4.2. Electrical connections to user inputs and outputs
See control unit manual.
13.4.3. Setting Functions from the Control Unit
The default value of all inputs and the remote pressure sensor is Disabled, so in order to use them, they must be activated by the user
see chapter Setup of the auxiliary digitali inputs IN1, IN2, IN3, IN4 and PR: Remote pressure sensor.
