• Carefully read this manual in all its parts.

• Installation and maintenance must be carried out by qualied personnel responsible for establishing the electrical connections in accordance with the existing rules and regulations.

• The manufacturer does not accept any responsibility for damage caused by maintenance or repairs carried out by unqualied personnel and /or by spare parts which are not original.

• The use of spare parts which are not original, tampering or misuse will result in the forfeiture of the guarantee. During the initial installation and in case of maintenance make sure that:

• The power supply has been switched o

• The power supply is provided with safeguards and in particular a highly sensitive circuit breaker (30 mA in class A for domestic applications and in class B for industrial applications) and grounding in conformity with the rules.

• Before removing the lid of the inverter or starting procedures on it the power supply must be disconnected before waiting at least ve minutes so that the capacitors have the time to lose their charge through the incorporated discharge resistors.

• Do not remove the board cover and/or disconnect the electricity to the pump if the inverter is in operation.

• WARNING: when the TISSEL-200 is out of service (red LED ashing) it is still electrically charged. Before any form of intervention on the pump or on the inverter it is obligatory to disconnect the power supply to the pump. Emergency Stop Whilst the TISSEL-200 is in operation it is possible to carry out an emergency stop by pressing the OFF/ON switch.28 | ENGLISH

DESCRIPTION OF THE PRODUCT

TISSEL-200 is a speed regulator with the following characteristics.

• Input is a single-phase alternating voltage.

• Supplies a three-phase alternating voltage.

• Keeps the pressure of the installation constant (curves with variable revolutions).

• Controls the hydraulic and electrical operating parameters, and protects the pump from faults.

• It can be tted with an expansion card which enables it to work in parallel with other inverters in the pump units and to man- age an input signal and an output signal.

• It adapts to function with any type of pressurisation plant including current ones.

• It is energy saving as it limits the start-up and operating electric current.

• Allows the selection of the supply and output voltage.

TISSEL-200 is live but the pump is not running (STAND-BY) TISSEL-200 is live and the pump is running TISSEL-200 is live but OUT OF SERVICE (or in TEST), restoration is only manual TISSEL-200 is in a state of alarm, restoration is only manual30 | ENGLISH INSTALLATION

6. Foot valves with suction lter

During both the rst installation and maintenance ensure THERE IS NO POWER in the line During both the rst installation and maintenance ensure the plant is UNPRESSURED DO NOT OPEN THE COVERS OF THE INVERTER In addition ensure that the electricity supply has protections and in particular has a dierential switch of great sensitivity (30 mA in class A for domestic applications and in class B for industrial applications) and grounding in conformity with the regulations. Verify that the data on the plate are those desired and that they are adequate for the installation. Install TISSEL-200 in a place: – protected from external agents – ventilated, free of excess humidity or too much dust – where it does not suer from harmful vibrations or mechanical stresses from the tubes connected to it.

POSITIONING OF THE PRODUCT

• Fix the unit with screws onto a solid horizontal base.

• If the pump has to be installed externally where it might freeze protect it to avoid freezing. IMPORTANT For the correct functioning of the TISSEL-200 the installation of an adequate expansion tank is absolutely necessary.

• The expansion tank: – Accumulates water under pressure in order to reduce to a minimum the start of the pumps. – It is indispensable in the presence of small losses of the installation. – It absorbs eventual over-pressures coming from the plant. – The minimum volume required in litres (for models with a membrane) is indicatively equal to 10% of the maximum ow rate of a single pump, expressed in l/min. Example of a standard application: Qmax = 80 l/min Æ V = 80 x 10% = 8 litres (rounded up by excess to the commercial size) – Pre-load pressure (with an empty plant): approximately 70% of the work pressure: Example: Pset = 4 bar Æ Pre-load pressure = 4 x 70% = 2.8 bar

• Correctly connect the supplied pressure sensor to the installation (see next chapter). PRESSURE SENSOR A pressure sensor is a transducer which measures the pressure of a liquid or a gas by means of an electrical signal sent to a receiver in analogue format. Pressure sensors are therefore also called pressure transducers. The operating principle is based on the physical deformation of the strain gauge lament present in the membrane of the trans- ducer: the electrical resistance is proportional to the applied pressure, which is converted into an electrical signal, the exit is transmitted as a current which varies from 4 to 20 milliamps. The pressure sensor should be indicatively positioned in the installation as shown in the drawings (see previous page)32 | ENGLISH ELECTRICAL CONNECTIONS

• The electric connections between the pump and the inverter are implemented in full in the factory and therefore for its func- tioning nothing needs to be done.

• TISSEL-200 is connected to the electricity supply (230 V/50 Hz) by means of an electric cable.

• Before switching on read the attached manual and follow the instructions, in order to avoid errors in settings and operations which could cause anomalies in functioning.

• Do not switch on the pump when it is dry, not even for a few seconds.

• Before switching on the pump, prime the pump.

• Insert the plug in the socket.

• Press the switch (1) and wait for it to START (about 10 seconds).

• After 10 seconds the STARTING phase ends and TISSEL-200 returns to the same operating conditions which it was in when it was last switched o: – IN SERVICE if when it was last switched o it was IN SERVICE. – OUT OF SERVICE if when it was last switched o it was OUT OF SERVICE (OFF). In the case of an accidental fall in power, if TISSEL-200 was IN SERVICE (ON), when the power returns it will automatically return to IN SERVICE (ON).

• To put TISSEL-200 in service press the key (2) ON/OFF on the control panel.

• TISSEL-200 starts to function.

• If the pump is not correctly primed place Tissel-200 into the TEST mode (manual control) and gradually open the delivery valve (for its functioning in TEST mode see the respective chapter later in this manual). ATTENTION: the inverter is perfectly congured in accordance with the predened factory settings, in order to function correctly with the associated pump. If it were necessary to modify the factory settings of the TISSEL-200 set the inverter using the parameters in the HIDDEN LIST (see chapter SETTING UP PARAMETERS IN THE HIDDEN LISTS).34 | ENGLISH

DEFINITION OF THE SWITCH OFF FREQUENCY

(only possible in the AUTOMATIC FUNCTION mode)

• The switch o frequency is a dened minimum frequency threshold and as long as the functional frequency is above this threshold (namely there will be a demand for water) the inverter will keep the pump switched on. When the frequency of operation falls below this threshold (namely there will no longer by a demand for water) the inverter stops the pump. P 3,5

CALIBRATION OF THE PRESSURE SENSOR

In order to calibrate the pressure sensor the following must be supplied:

• A value of ZERO (system at zero pressure).

• A reference value (eg. system at 5 bar). It is necessary to have:

• An auxiliary manometer on the same mandate circuit of the inverter.

• Set the pomp in action (open a tap). To access the calibration, starting with the INVERTER in STAND-BY P 3,5 STARTING within 10 sec.

Inverter in STAND-BY Remove the current Wait 30 sec. Restore current During the STARTING phase (time 10 sec) press the 4 arrows SIMULTANEOUSLY Calibration SP 0,0 SP 5,0

Requires the ZERO bar reference If P in system = 0 Conrm with SET Requires the 5.0 bar reference If the pump does NOT reach 5 bar REDUCE the reference pressure Open a tap Switch on the pump Verify the pressure in the system

SP 5,0 OFF Increase the velocity of the pump until the set reference pressure is reached on the manometer Conrm the reference pressure Calibration accomplished43ENGLISH | ALARMS OVER CURRENT Alarm due to overcurrent greater than the planned tolerance. The inverter stops the pump; the reset is only manual. CURRENT LIMIT Alarm due to overcurrent greater than the capacity of the module The inverter stops the pump the reset is only manual. DRY RUNNING It arises if the pump is unable to reach the pre-set percentage of the set pressure, expressed by the parameter Pd (see Chapter SETTING OF THE ADVANCED PARAMETERS); the inverter stops the pump. The error is zeroed after the TP time (see chapter SETTING OF THE ADVANCED PARAMETERS). DRY RUNNING PF It arises if the electrical parameter COSFI falls to the value which indicates the dry running of the motor. The inverter stops the pump. The error is zeroed after the TP time (see chapter SETTING OF THE ADVANCED PARAMETERS). P ERROR It arises if the control card does not receive the signal from the pressure sensor. The error is automatically cancelled on receipt of the signal. LOW PRESS It arises if the pump is rotating at maximum frequency in the presence of a ow, and the pressure does not reach the value of the parameter LP (see chapter SETTING OF THE ADVANCED PARAMETERS – default 0.2 bar); the inverter stops the pump. The error is overcome after the TP time (see chapter SETTING OF THE ADVANCED PARAMETERS). LOW VOLTAGE A drop in voltage has been registered (even very briey) which exceeds the functional tolerance (-15%); the inverter stops the pump; the error is overcome after one minute and the inverter restarts automatically. HIGH VOLTAGE A surge in voltage (even very briey) which exceeds the functional tolerance (+15%) has been registered; the inverter stops the pump; the error is overcome after one minute and the inverter restarts automatically. OVER TEMP. The temperature of the module of the inverter has reached the critical threshold. The inverter stops the pump, the error is overcome when the temperature falls below 70°C and the inverter restarts automatically. COM ERROR There has been an error in the internal communications; if the error persists the electronic cards could be damaged. LOW LEVEL It arises when the digital entrance EI is congured as a signal of the level (EI = 1 – see chapter SETTING OF THE ADVANCED PARAMETERS), and the signal is not present. When the signal returns the message disappears and the inverter returns to function normally. EXT OFF This arises when the digital entrance EI is congured as being activated by an external order (EI = 2 - see chapter SETTING OF THE ADVANCED PARAMETERS), and the signal is not present. When the signal is again present (external restoration) the message disappears and the inverter returns to function normally.44 | ENGLISH
