8 4. INSTALLATION Ensure that the mains power supply specifications correspond to the voltage specified on the data plate of the electrical panel and motor connected, then make the earthing connection before all other connections. STARDELTA-EN 3~400V ± 10% 50/60Hz The power line must be protected by a residual current circuit breaker. Tighten the electrical cables on the relative terminals using a suitable tool correctly sized to avoid the risk of damage to the fixing screws. Take care if using an electric screwdriver. The electrical panel is designed for wall-mounting using screws and plugs in the pre-drilled holes at the corners of the enclosure, or by means of brackets when present. Install the equipment in areas compliant with the protection rating and ensure that the box is kept intact when drilling the holes for fitting the cable clamps. Avoid the use of multicore cables where there are wires connected to inductive loads and power cables and signal cables such as sensors and digital inputs. Keep connection cables as short as possible, preventing any twisting of cables which may be harmful due to inductive effects on the electronic equipment. All wires used in the cabling must be suitably sized to withstand the load to be powered. 8

9 4.1 Electrical power line: Make the ground connection before all other connections. Ensure that the mains voltage corresponds to the specifications on the electrical panel data plate: Ensure that the power cable is able to withstand 150% of the maximum motor current (according to EN Para ) and connect it to the terminals of the main disconnect switch of the electrical panel. The line must be protected in compliance with current standards. 4.2 External command lines In automatic mode, the electric pump is started via normally closed voltage-free contacts (pressure switches); A normally open voltage-free contact (priming tank float) protects the system against potential dry running conditions; Make the connection with the control panel switched off and the main switch (UPLINE of the panel) turned off, taking care to observe the connections as shown in the attached diagram. 9

10 5. OPERATION This device enables management in AUTOMATIC, MANUAL or EMERGENCY mode of an electric pump in accordance with standards EN When necessary, the electric pump is shut down automatically in a pumping system with exclusive use of the network of hydrants (as envisaged by standard UNI July 2007). When the panel is switched on, the display is activated with a brief general check-up lasting a few seconds, after which the control unit displays the control parameters. When the electrical panel is switched on, the system sets up for AUTOMATIC mode, and only when necessary can be set to MANUAL mode by pressing the START button. The panel is equipped with an AUTOMATIC-EMERGENCY selector with key that can be removed in the AUTOMATIC position, to activate the following operating mode: 5.1 Automatic mode With the key set to AUTOMATIC (the key is removable in this position); otherwise automatic start-up is inhibited, as signalled by the flashing indicator (automatic start-up inhibited) and display of the message: AUT. START-UP INHIBITED. When the control unit detects opening of the starting contact (pressure switches), it starts up the electric pump. The control unit controls (without stopping the pump) any faults on the motor during its operation. Automatic start-up occurs on opening of the contacts on the starting pressure switches, indicated by illumination of the indicator for start-up request from the pressure switches. After any closure of the pressure switches, this indicator starts flashing. Automatic start-up occurs also on closure of the contact of the pump priming float; this is indicated by the steady indicator light. After opening of the contact, the indicator starts flashing. The flashing signals continue for the entire duration of motor operation. 5.2 Manual mode To manually start up the electric pump (useful when testing the system), press the START button of the control unit, taking care that the AUTOMATIC-EMERGENCY selector is set to AUTOMATIC. 10

11 5.3 Emergency mode The system envisages the option of manual start-up in EMERGENCY mode in the event of a fault on the electronic control unit or power supply system to the latter. When the key is set to EMERGENCY, this immediately activates the electric pump control contactor (the motor is started up in DELTA mode) by-passing all electronic controls of the panel. This means that the operator will start up the pump. 5.4 Shutdown The motor can only be shut down manually. It cannot be shut down when there is a request from pressure switches or automatic start-up is enabled. If the pressure switch request is activated even when the stop button is pressed, the electric pump does not shut down and the control unit display shows the message: DO NOT SHUT DOWN IN THE EVENT OF FIRE - SHUTDOWN INHIBITED If the pressure switch request is deactivated when the STOP button is pressed, the electric pump shuts down and the control unit display shows the message: DO NOT SHUT DOWN IN THE EVENT OF FIRE In normal operating mode, the MOTOR RUNNING condition (controlled by the amperometric reading) is indicated by the light which turns on when the pump current remains above the set threshold for the entire duration of the intervention delay. Start-up controlled by the pump pressure switches is indicated by the light and is detected once the motor has started up and the pump pressure switch closes before elapse of the intervention delay. START-UP FAILURE is indicated by the light. After a request for automatic start-up of the motor, the START-UP FAILURE status is detected when the power value (KW) of the pump motor remains below the set threshold for the entire duration of the intervention delay, or when the pump pressure switch does not close and the intervention delay elapses. 11

12 6. LUMINOUS INDICATORS AND BUTTONS The user can scroll through the various values by means of the button. 12

13 7. ALARMS The alarms do not cause shutdown of the pump, but are signalled via the relative indicator, the cumulative led, a message on display, and switch the contact (availability of electrical power) to enable remote monitoring. MOTOR POWER SUPPLY ALARMS: Lack of or drop in mains power, even on a single phase. Incorrect phase sequence or fuses blown. MOTOR ALARM: Overcurrent SYSTEM ALARM: Faults on pressure switch for pump in pressure The alarms can be reset by pressing the button : the safety devices are enabled and the startup cycle is released, controlled by the priming tank float. 13

14 8. AUTOMATIC CALIBRATION Automatic calibration enables automatic programming of the thresholds for PUMP RUNNING and START-UP FAILURE. To perform AUTOMATIC calibration, start up the pump primed with delivery closed: then with the key selector set to AUTOMATIC, press the button. Press and hold the three buttons simultaneously to display the message AUTOMATIC CALIBRATION, and keep pressed until the message PROGRAMMED appears on display. On completion of AUTOMATIC CALIBRATION, the following results are obtained: Programming of the threshold for PUMP RUNNING (controlled by the amperometric reading) for a current equal to half of that delivered with the pump running with delivery closed. The threshold is exceeded when the pump current remains above the set threshold for the entire duration of the intervention (5 seconds). Example: Programming of the threshold for START-UP FAILURE (controlled by the power value KW) for a power equal to 20% less than the power with pump started up with delivery closed. The threshold is exceeded when the power value remains below the set threshold for the entire duration of the intervention (5 seconds). Example: 14
