1. General About this document The language of the original operating instructions is French. All other languages of these instructions are transations of the original operating instructions. These installation and operating instructions are an integral part of the product. They must be kept readily available at the place where the product is installed. Strict adherence to these instructions is a precondition for the proper use and correct operation of the product. These installation and operating instructions conform to the relevant version of the product and the underlying safety...

and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. If hot or cold components on the product/the unit lead to hazards, local measures must be taken to guard them against touching. Guards protecting against touching moving components (such as the coupling) must not be removed whilst the product is in operation. Leakages (e.g. from the shaft seals) of hazardous fluids (which are explosive, toxic or hot) must be led away...

• Weld-on (Steel) or screw-on (Stainless Steel) counterflange. • Non-return valves (with nose or spring ring when operating in constant pressure). • Strainer-foot valve. • Vibrationless sleeves. • Protection kit against dry-running • Sensor kit for pressure regulation (accuracy : ≤ 1 % ; use between 30 % and 100 % of the reading range). 5. Installation Two standard types. Fig. 1: pump in suction Fig. 2: pump in load on storage tank (item 9) or town water supply (item 10). Altitude 5.1 Montage - Install the pump in a place easy to reach, protected against frost and as close as possible from...

Power terminals Connect the 4 wires cable on the power terminals (phases + earth). Not used Remote control ON/OFF • The sensor, external setpoint and [ext.off] inputs cable must be necessarily screened. Inputs / outputs terminals Connection of inputs / outputs Connection to mains supply Example: Float switch, pressure gauge for dry-running… • The remote control allows the switching On or Off of the pump (free contact), this function has priority on the others. • This remote control can be removed by shunting the terminals (3 and 4). Connection terminals of the interface PLR The optional...

DANGER! Danger of death! Contact voltage hazardous due to the discharge of the converter capacitors. Before any intervention on the converter, wait for 5 minutes after disconnecting of the supply voltage. Check whether all electrical connections and contacts are voltagefree. Check the righ allocation of the connection terminals. Check the right earth connection of the pump and installation. Control laws IN1 : Input signal in « Constant pressure » and « P.I.D. control » mode Between 0 and 2 mA, cable is considered as broken Safety area in % of the range of measurement of the sensor in % of...

6.1.3 Description of standard symbols 6.1.1 Control elements The converter operates using the following control elements: Operating in « Speed control » mode. 2 Setting with encoder Operating in « Constant pressure » or « P.I.D. control » mode. Input IN2 activated (external setpoint). Access locked. When this symbol appears, current settings or measurements cannot be changed. Information displayed is only in reading. • The selection of a new parameter is done only with a simple rotation, « + » on right and « - » on left. • A short impulse on the encoder validates this new setting. Switch...

Navigation element • The arborescence of the menu allows to call the functions of the converter. A number is attributed to every menu and submenu. • The rotation of the encoder allows the scrolling of a same menu level (example 4000->5000). • Any blinking elements (value, menu number, symbol or icon) allow the choice of a new value, a new menu number or a new function. Symbol Description Only reading for the « Information » menu. • The « Information » menu displays measuring, device and operating data, (Fig. 12). <5.0.0.0> Position When the arrow appears: • An impulse on the encoder allows...
