Installation

Operation

It is possible to replace the connections (supplied as spare-parts and included in the package) on the inlet and/or outlet of the device, depending on the system requirements, without compromising its operation.Mount the device in a vertical position directly onto the pump or between the pump and the first tap.While not necessary to install a ball valve between the device and the system, this makes it possible to identify whether any anomalies derive from the device or the system.Carry out the electrical wiring and energize.On the panel, the green “Power On” Led and the red “Off” Led light up and blinking dashes appear on all the displays while the device performs the setup.At the end of the setup, the current values and the pressure set in the factory will appear (CURRENT 1.5 A- SYSTEM PRESSURE 3.0 Bar – CUT-IN PRESSURE 1.5 bar) and the “CURRENT” display will start blinking.Now set the first current value absorbed by the motor as indicated on its nameplate.To adapt the system to the desired operation, it may be necessary to change the factory-set values: system pressure 3 bar- cut-in pressure 1.5 bar.The set pressure value of the system must be less than the maximum effective pressure generated by the pump and compatible with the desired pump delivery.The set cut-in pressure value must be less than the maximum effective pressure generated by the pump and higher than the pressure delivered by the height of water column exerted on the device.

EXAMPLE OF SETTING PARAMETERSCurrentAdjustment step 0.5A up to 10A – 1 A above 10 ASet the value immediately after the value indicated on the nameplate.Example: motor absorption (nameplate data) 6.3 A ! max. 6.5 A

System pressureAdjustment step 0.5 bar.Set the desired value provided it is lower than the maximum effective pressuregenerated by the pump.Example: maximum pump pressure 9 bar ! max. 8 bar

Cut-in pressureAdjustment step 0.1 bar.Set the desired value provided it is higher (~ 0.5 bar) than the pressure generatedby the water column.Example: water column pressure 1 bar ! min. 1.5 bar.

After setting the values press the green “ON” button on the switch (green Led lit up) to turn on. The set pressure values can also be changed while the pump is operating.

The device varies the number of motor revolutions of the electric pump depending on the water withdrawn by the system in order to maintain a constant delivery and pressure, provided compatible with the characteristics of the relative electric pump and the system.

• In case of malfunctioning, the device will stop the pump, the red “Failure” Led will start blinking on the panel and the respective code will ap-pear on the “CURRENT” display. Example: H1 incoming water shortage.

• In case of failure, the pressure sensor (available on request as spare-parts) can be easily replaced even by the user without removing the device from the system.

• In case of a pump stop due to an input water shortage, the device will automatically make 6 double attempts to rearm the pump, according to a tredetermined sequence to allow the system to reload after the pump stop. After the last failed attempt to rearm, the device will remain permanently in “Failure” status (blinking red Led) pending manual rearming by pressing the red “Restart” button.

The user can rearm the device at all times by pressing the red “Restart” button.• If the pump remains stopped for 24 consecutive hours for any reason, the device will carry out a start up of the pump motor of approximately

5 seconds (anti-jamming function).• In case of blackout, the device will automatically rearm once the electricity returns.• The device is designed for the connection of a command and / or an alarm (light and siren) remote, a float switch and / or a level probe.

The device can be fitted on request of additional keyboard to access to the serial output RS 485 to allow communication between two or more devices of the Logic series and a device with a control panel if enabled for communication.

Electronic FlowswitchStarts and stops the pump and protects it from dry running

Logicflow is also available in the “Special” version equipped with automatic restarts.

LOGICFLOWMade in Italy

The device must be mounted in a vertical position. In order to operate, the flowswitch requires a minimum flow that passes through it when a tap of the system is opened. For this reason the device and the system tap must be installed underneath the tank (Fig. 1 - Fig. 2). It stops and starts the pump depending on the opening and closing of the system taps. It stops the motor and saves the pump in the case of a water shortage. To restore normal operation to the device and the system simply press the red “Restart” button. In case of a blackout, it will automatically rearm again several seconds after the electricity returns.

Electronic Motor-SaverStops the motor and protects the pump in case of water shortage and overcurrent.

LOGICSTOPMade in Italy

In order to operate, the electrical power supply of the pump must be connected to the mains. For this reason the power supply plug of the pump must be inserted in the socket of the device which is in turn connected to the power point (Fig. 1). In case of a water shortage on suction, the device will stop the pump and protect it against dry running. This malfunctioning is indicated with the red “Failure” Led lit up. In case of the current absorption exceeding 8 amperes, the device will stop the pump motor and protect it against over-current. This malfunctioning is indicated with the red “Failure” Led lit up. To restore normal operation to the device and the system simply press the red “Restart” button. In case of a blackout, it will automatically rearm again several seconds after the electricity returns.
