BEFORE INSTALLATION AND USE READ THE FOLLOWING INSTRUCTIONS CAREFULLY. THE MANUFACTURER DECLINES ALL RESPONSA-
BILITY IN THE EVENT OF ACCIDENT OR DAMAGE DUE TO NEGLIGENCE OR FAILURE TO OBSERVE THE INSTRUCTIONS DESCRIBED IN
THIS MANUAL OR IN CONDITIONS THAT DIFFER FROM THOSE INDICATED ON THE DEVICE.
OPERATION
Is a wall mounted automatic control device designed for the automation of single-phase borehole pumps. It inclu-
des a frequency inverter that modulates the speed of the pump in order to keep constant the pressure indepen-
dently of the flow given.
The system incorporates an LCD screen where the parameters configuration is very easy and intuitive. Once the con-
figuration parameters are set, the device manages the start-up of the pump and the frequency inverter. It assures
a constant pressure and an important costs reduction because at any time the control will feed the system with the
right and necessary output, obtaining a maximum energetic efficiency.
It is also integrated a 16A MCB in order to protect the pump and the unit against overcurrents. Finally are also inclu-
ded fixing and positioning elements to locate the capacitor of the submersible pump.
MASTER AND SLAVE OPERATION
The group MASTER-SLAVE is constituted by a device configured as MASTER - responsible of the group´s control - and
another device configured as SLAVE controlled by the master device.
Due to the alternating sequence of operation, the device configured as MASTER began the first cycle as MAIN devi-
ce - its pump is the first to start - but in the next cycle it becomes SECONDARY - its pump is the second to start - and
so on. Therefore, the fact that a device is configured as MASTER involves control of the group but this fact does not
avoid its operation alternately as SECONDARY device. Each device must be provided with its transmitter.
MAIN CHARACTERISTICS
• Wall mounted frequency inverter for the pump control.
• Integrated 16A MCB.
• Control and safety system against over-intensities.
• Control and safety system against dry operation.
• ART function (Automatic Reset Test). If the device has been stopped due to the action of the safety system
against over-current, the ART tries to connect the pump, with a programmed periodicity because the water
supply could have been restored
• Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC mode kee-
ping the configuration parameters (see "CONFIGURATION" chapter).
• External pressure transducer (4..20 mA) under demand.
• Possibility of communication with another device to operate in MASTER & SLAVE regime
• Control panel (Fig.1):
• Display with back light for alarm menu with permanent pressure indication as digital gauge.
• START/STOP, ENTER, MENU and ON/OFF push-buttons.
• Keyboard for the access to programming menu.
• Indication led-lights.
• Connections for detection of minimum water level in aspiration tank. This system is independent of the safety
against dry operation. Is optional.
• Common alarm volt-free contact (under request).
• Register of operational controls: infomation about operating hours, counter of starts, counter of connections to
the power supply.
• Register of alarms: information about type and number of alarms since the starting up of the device.
