5 1. GENERAL REMARKS 1.1 Standard supply module 1 The converters of the wave range have one single supply for more modules, even if these are heterogeneous. The standard supply module consists of two distinct sections: signals and power. The supply functions are described below Supply of control electronics Through an internal switching supply the module gets from the power dc (+/-dc bus), the 24Vdc needed to supply the whole control electronics of the tunnel and also possible external loads (such as encoder). It also gets +5Vdc for the programming keyboard supply and +/-10Vdc for the external potentiometers. KEYBOARD SERIAL CABLE COLOURED FLAT CABLE SUPPLY TO THE POWER MODULES TO THE FAN MODULES ELECTRICAL CABINET Supply of power electronics It rectifies the ac mains and builds a continuous voltage that, after being filtered by the capacitor modules, supplies the power modules sections. MAINS 1. supply module: rectifies the ac mains 2. capacitor module: filters the supply s voltage 3. and 4. Power module: handles the motor directly and changes its speed. 1.2 Technical features

7 2. INSTALLATION 2.1 Power connections The modules have different sizes, different for deliverable nominal current. The fixing of power cables changes according to sizes: sizes connection on bolt terminal M6 sizes connection through double bolt terminal M6 size 05 connection through bolt M6 on aluminium bar 2 See enclosures Electrical power connections to find map, overall dimensions and connection diagram. 2.2 Signal and control connections The module versions 010 and 011 have two terminal boards for signal connections, one of which is dedicated to connections external to the tunnel, the other one for interconnecting with board 5324 in case of double tunnels (a single supply module with two tunnel parts: see general section). It has also a 20 way- flat connector for interconnecting of the power modules. Versions 012 and 212 have only one terminal board for signal connecting and two 20- way flat connectors for interconnecting of the power modules.

11 3. COMMISSIONING 3.1 General remarks The general section describes all measures and precautions to be taken before putting the device under voltage. That section should be carefully read before feeding the drive. 3.2 Alarm configuration jumper A jumper on the supply module s board allows to choose the tunnel s working in case of an alarm generated by a single power module. The jumper is shown in the map below: 3 SERIAL LINE RS485 Board configuration 010 and 011 version SERIAL LINE RS485 Board configuration 012 and 212 version Note: See also chapter Product versions

12 Jumper 1-2 In case of alarm all inverters belonging to the tunnel are desabled as well as the enabling (standard configuration). Jumper 2-3 In case of alarm only the inverter involved is desabled as well as the enabling output. Such configuration is to be preferred when the machine requires the stopping of the other motors with controlled deceleration. 3.3 Configuration Dip Switch SW1 mains voltage selection Version 012 and 212 (see chapter Product versions have a dip switch called SW2 allowing to select different mains voltage values as planned for the AC WAVE series. 3 DIP SWITCH NO. FUNCTION DEFAULT 1 not used OFF 2 not used OFF 3 mains voltage selection ON 4 mains voltage selection ON The selection logic of dip switch 3 and 4 is the following: DIP 3 DIP 4 MAINS VOLTAGE ON ON V ON OFF 415V OFF ON V OFF OFF not used Dip switches can be seen on map below: SERIAL LINE RS485

15 4. OPTIONALS 4.1 Optional braking module For particular applications, where the working cycles are very charged and decelerations extremely quick, it might be necessary to add a braking unit, in order to limit the unavoidable voltage increase on the dc link during the energy recovering phase. The resistance value to be applied to the braking unit has to be chosen according to the max. urrent the unit itself can endure. NB: The braking circuit checks voltage on the dc link but not current and temperature of the recovery resistor. It is therefore recommended to insert a thermal protection circuit for the resistor itself that will disable the drives when necessary. The power of the dissipation resistor and the braking module s size have to be chosen according to the working cycle. The chart below shows the minimum resistance values to be applied according to the supply module s size. SIZE DELIVERABLE POWER MINIMUM OHM VALUE kva (braking outside the module) /120 kva kva kva kva 3 NOTE: The optional braking module must be ordered together with the supply module, as the braking board cannot be connected after the supply module assembling. On demand, the dissipation resistors can also be supplied by Reel.

16 4.2 Additional braking module An additional braking module was developed only for size 01 (deliverable power 60kVA) that is not integrated in the supply module. This very compact module already has the dynamic braking resistor built inside. In order to increase the radiating surface, it would be better to choose a panel fixing. The modules has only four bolt terminals: +600 for direct connection to the tunnel power bus -600 (dc link) +P for direct connection to the 24Vdc connector s output signal OP connection (pin 08/09 and 06/07 of P5) The Multi-Voltage version gives the possibility of selectig the mains supply through the dip switch shown on the drawing below, according to the indicated chart. 4 JUMPER RETE ac ON OFF Overall dimensions and map are shown below: L= 260 H = 90 P = 85 The integrated resistor has nominal value W (2,2kW for 5 seconds)

17 4.3 Control board and braking protection In order to protect the dynamic braking resistor from a thermal point a view (which is often installed to achieve stop in shortest time, also in case of strong inertial mass), Reel has developed a circuit able to check the power being dissipated. It is a board to be installed in the electrical cabinet, with a parallel connection to the resistor (to measure insertion times) and an interface with the electric devices. It shows the maximum braking alarm through a double contact relay and is therefore very versatile in application. There is a single 24Vdc supply that can be also taken from the supply module directly (terminals 8/9 and 6/7 of terminal board for connection signals). The message regarding the occurred alarm stays and can be reset with a 24Vdc impulse on the related input.

18 The board reads the voltage applied to the braking resistor s ends constantly and increases the timer slowly or quickly, according to the power measured at each moment. While the resistor is resting, the timer is decreased. As soon as the timer reaches its limit value, an alarm memory is activated. The circuit has two LEDS indicating the state: L1 green on: start enablement L1 green off: occurred alarm L2 yellow blinking: timer increasing Only two trimmers set the features of the resistor to be protected: Trimmer RV1: setting the overload ratio Trimmer RV2: setting the maximum overload Board setting Foreword The dynamic braking circuit dissipates on the resistor the exceeding energy during the temporary recovery due to the braking through the driving force mass. Energy is dissipated with high instant power peaks, while the effective value is considerably lower. The control tasks are: instant power measuring and comparison with the nominal power (rated value of the resistor used); calculating the overload as sum of instant powers; activating an alarm at the set value.

19 4.3.3 Setting of overload ratio trimmer RV1 The dc link s voltage values at which the braking resistor is inserted are the following: for mains = 660Vdc for mains = 780Vdc Once the resistor s ohm value is known, the instant power can be calculated with the following formula: V = value of intervention voltage R = resistor s ohm value V 2 = instant power R The overload ratio is calculated with formula: PI = overload ratio PN 4 PI = instant power PN = nominal power (rated value) Trimmer RV1 has to be set according to the calculated overload ratio: ratio 20 = trimmer in zero position ratio 3 = trimmer in 100%position intermediate trimmer positions determine ratio values between 3 and 20

20 4.3.4 Setting of maximum overload trimmer RV2 The maximum overload allowed by the resistor can be taken from the rated data or the resistor s technical sheet. The setting of trimmer RV2 can be seen on the chart below, that shows the intervention according to setting made on trimmer RV1. % SETTING TRIMMER RV2 4 INTERVENTION TIME (sec.) Example: rated data mains: 380Vac resistance: W 6.6Kw for 5 seconds RV1 setting NB: mains 380V corresponds to intervention voltage 660V instant power = V 2 = = 24,2Kw R 18 overload ratio = PI = = 26,8 PN 900 position of trimmer RV1 = 0% ( ratio 20) RV2 setting

21 To consider: the resistor is rated 6,6Kw for 5 seconds; being the instant power 24,2Kw, it can be deduced that limit time at that power value is: 6,6 x 5 = 1,36 seconds 24,2 Setting of RV2 can be taken from the chart above: % SETTING TRIMMER RV2 4 INTERVENTION TIME (sec.) RV2 setting = 88% Default setting Reel supplies the board with: trimmer RV1 = 0% trimmer RV2 = 100% The intervention limit time of the integrator at such setting is 1,6 seconds with mains 380Vac.

22 4.4 Integrated programming keyboard The supply module can integrate the keyboard described in he general section, under Parameter input. The keyboard is fixed on the supply module s front side and completes the tunnel by giving the user programming support as well as alarm diagnostics. NOTE: The keyboard communicates with the modules through serial line RS 485 (9 pole connector sub D of the supply module). It can be therefore installed in case the user should use the serial line. See general section for any information on the device. 4

23 5. ANOMALY SOLUTION GUIDE 5.1 Luminous warnings The supply module has a little bar with 10 warning LEDS, whose function is marked. The warnings are very helpful for the running state or anomaly diagnostics. PWR msr RUN TS EN OK HLD RST +/- RSI PWR power: when on, it indicates that 24Vdc is given OK ready to start: f off, it means that an anomaly is occurring msr minimum speed relay: if on, it means that at least one of the motors is rotating HLD hold: if on, it means failure of at least one of the power phases 5 RUN run: if on, it means that the power modules have been enabled RST reset: gets on only when alarms are reset TS thermal sensor: if on, it indicates the intervention of one of the thermal sensors placed on the power radiator +/- +10V -10V supplies: if on, it indicates that power supplies +/-10V are given EN enable: if on, it means that enabling input is on RSI input reset: if on, it means that reset input is on The LEDS can be seen on the map below:

25 5.2 Machine state and alarms Indication on machine state: tunnel is on, but not enabled; following LEDS are on: PWR; OK; +/- tunnel enabled, while motors stand still, following LEDS are on: PWR; OK; RUN; +/-; EN If one motor is rotating msr goes also on Anomaly state Note: Any kind of alarm switches OK off. LED ST, when going on, means: lacking ventilation check w orking of radiator' s fan Thermal sensor intervention of thermal sensor placed on pow er dissipator w eak heat exchange check cooling air and control board temperature 5 too heavy w orking cycle check average current of w orking cycle to be correct according to set parameters if LEDS PWR or +/- are off or weak, they mean overload of the supplies +/-10V o 24Vdc when LEDS are blinking, they warn on a short circuit or an overload on one of the supplies. In this case disconnect the loads in order to find the short circuit, following the steps below: 1. Disconnect the supply s output terminal board 2. Remove programming keyboard 3. Disconnect he coloured flat cable from the modules Once the short circuit cause has been found out, remove it. If no power module shows an alarm state and only the OK LED is off, that means that a minimum or maximum voltage alarm is occurring:
