- The hour meters are instruments for measuring time which are particulary suitable for:- determing the functioning time of electrical machines, elevators, boilers, electrical stoves etc.- determing the intervention time for changing the oil, replacing ball bearings etc. on machinery that is in constant use.- determing the functioning time of new machinery with the purpose of establishing when the guarantee expires, such as current rectifiers,

valves, lamps etc.- determing the sum of the periods during fatigue tests, the duration of electrochemical processes etc.

- In the DC version the movement of the motor is adjusted by a quartz crystal with great stability and a frequency such that, at every 22 degrees of oscillation,an impulse is released when amplified, activates electromagnetic converter. The display is composed by 6 entires and 1 decimal (4 mm height)

- At the end of the counter, the counting begin again automatically from zero. It is not possible to reset the device.- The necessary voltage is 1,2....1,6V.- The precision is obtained by means of a variable condenser with a tolerance of +/-0,2 sec/day at room temperature.- Operating temperature: between -10°C and +55°C. Mounting position is indifferent and the housing is in black plastic material.- The reading class is 1/100 h (36 sec). This hourmeters are manufactured following the UL, IEC, TGL21-366, DIN Standards

AC+DC value(if voltmeter)

AC+DC value(if ammeter)

PUSHED BUTTON RELEASED BUTTON DESCRIPTION

To enter in programming page, make a long pressure (4 seconds about) on the front button. When the programming request is recognised “ Set” page appears. Releasingthe button all words will flash quickly, this situation will remain until the end of procedure. After 4 seconds the pages with configuration parameters start to be displayed;one every 4 seconds showing the actual selected value. If it is necessary to see the values without any modification don’t touch nothing until the automatic end of theshowed pages. To change the values of parameters, it is enough to press the frontal button while this parameter is displayed. To fast forward maintain pressure on thefrontal button. The value is automatically saved in permanent way when the automatic display of the pages starts again.

The following programming pages can be present or not depending by the model used.

End scale

VALUEfrom 500 to 9999

This page selects the end scale value (except the dicimal point) which must be shown when the input signal is maximum.For DC measurements there is simmetricity also for negative values obtained when the input polarity is inverted. Used incombination whit “SSc” parameter it permits personalized visualizations. Default value 500.0

It is the number (n) of single measures effected on the electrical parameter before it’s visualization on the display.Practically it is the filter of the measure stabilization. The numbering rise up from 1 to 255; more higher is the selectednumber, more slow are the eventual variations of reading. This is valid for all the measured parameters.Default value 30.

average

beginning scale

VALUE from-9999 to +9999

Select a beginning scale correction (except the decimal point) used to obtain a certain value when input signal is 0 or whenthe input signal is 0 or has an initial value. Default value 0.Pratical example of SSc and FSc parameters:from a converter you have a signal 4/20mA which rappresent a current 0-300A, we want that an ammeter with input 20 mA(calibrated to the max current 20mA) gives this indication. Solution: assuming that we need 4 mA = 0 and 20 mA = 300 = FScwe will use the formule: knowing that VALMIS at 4mA (with SSc = 0) is a direct proportion of FSc.

To have the SSc value (unknown) we use the following formule: putting VALMIS to 0.

Now is possible to have SSc value by the formule:

GENERAL DESCRIPTIONThe 4 DIN instrument is suited for use in industrial and civil market, specially on sectors related to the production of alternative energy (photovoltaic, wind energy) .Simple and extremely compact, it features an alphanumerical display with 2 lines of eight-character lines, 6 auxiliary LEDS and 2 buttons for display selection and key-board programming. The machine is extremely user-friendly and information is presented clearly on the display. It is unlikely you will need to consult instruction manualwhich is not generally kept readily available at the site. When properly installed, the instrument measures the current from external shunt ..60mV. The instruments havethe possibility to select the current end scale value between 5,0 A to 3000 A DC by steps of 5,0A.Two principal families (direct and “H” insertion) forecast respectively the voltmeter measure in DC direct insertion ( -800,.0 / + 800,0 VDC) or by external voltage divi-der …../ 100VDC. Other executions can be manufactured on request ( ex. 24VDC, 48VDC, 150VDC etc) but must be considered as “special executions” with differentcosts. The instruments related to “H” family have the possibility to select the voltage end scale value between 10.0V to 3000 V DC by steps of 1,0V.The high accuracy class measures offered by each instrument are the most used on the DC field. Every direct measure (Voltage, Current and Power) is bidirectional; sothe inversion of polarity is shown and the measured range is the same in positive or negative case; practically if the end scale is 3000.0A, these instruments are able tomeasure from + 3000,0A to – 3000,0 ADC. The individually resettable Energies and Ampere Hour can be easily calculated when you need to service the system and/or periodical test line operation, determinezone consumption values, establish cost centres, etc.

NOTE: The instruments use simple Energy and Ampere Hour totalizing methods for purposes of diagnostics and statistics. These instruments can-not be considered as substitute of Energy kWhmeters.

The following are provided according to model: 1 threshold with output on “N.O.” control relay (500mA/1000V), fully programmable (model “S”)1 x RS485 3kV optoinsulated programmable high speed interface with MODBUS RTU protocol (model “RS485)

GENERAL OPERATION (FOR ALL MODELS)The instrument calculates and monitors the electrical measurements of the plant to which it is connected. It displays the information on the selected pages of displayby quick pressure of the buttons. The right button is for “next” and the left button is for “previous” page. The 6 LEDS on the right help to indicate the main electrical measurement pages and switch on according to the type of measurement shown on the display at the time. The first measurement page that appears upon start-up can be programmed. The “S” models with threshold allow you to configure the measurement to be controlled, the type of threshold (off, maximum or minimum), the millesimal threshold valuein relation to the full scale of the controlled measurement, time delay upon activation or deactivation, if applicable, and the time delay in tenths of a second up to 25.5seconds (0=no delay). Refer to the “Programming” section for details on programming values and the “Operation of the programmable threshold” section.The “RS485” models with RS485 interface can communicate via network when they are assigned a programmable address between 1 and 255. You are advised notto put more than 32 devices on a network so as to ensure reliable communication. If this is not adequate, there are “special” versions able to support more than 64 devi-ces. Communication speed can be set at between 9600bps and 115,200bps.You are advised to set the communication speed at maximum if only these devices are used.If the speed is set too low and there are frequent requests and/or there is a high number of required records, interactions with the instrument may also slow down.Allmeasurements and parameters can be viewed on the MODBUS RTU reader interface.The instrument also enables “on the fly” remote programming of the work settings via the MODBUS writer interface with the respective records that support it. In certainsituations you are also allowed to carry out some macro-operations and controls, such as restoring the factory settings of models that enable this, resetting of the tota-lizers or direct switching on and off of the output relay for models with threshold.

Note: the “RS485” models offer additional measurements via MODBUS, in particular the TRUE RMS values to verify the presence or not of rippleor alternate components residuals.

All models feature a blackout indication page. It is like the measurement page but with flashing content which has to be programmed like the initial page shown on start-up.When you press the keys to change the measurement page, the “blackout” condition is reset. This is proposed again after any programming of the settings on the key-board. All models feature 2 hour counters; one for total operation and another that can be resetted. The latter allows you to check the average consumption if resettedtogether with one or more Energy totalizers.All models require a 3-digit password (that can be excluded) to change the work settings and reset the counters.This password is not intended to guarantee full protection but to prevent accidental access to the programming area and ensure the settings are not changed by someo-ne not authorized to do so.There is no easy way to recover or cancel a password that has been configured and then forgotten. You will have to try all the combinations or return theproduct to the factory for reprogramming.

OPERATION

When you start up the device, the firmware information page appears for a few seconds and all the LEDS switch on in sequence (initial diagnostics).You will then see, for a few seconds, the page with the “title” of the measurements that will appear on the display, and the respective LED will switch on if the page requi-res it to do so. When the first measurement page appears, you can press the buttons to scroll through the available pages.You can scroll FORWARDS by QUICKLY PRESSING the RIGHT-HAND button, or BACKWARDS by pressing the LEFT-HAND button.Pressing and holding the right-hand button will take you to the next page as well as allow you to program the instrument’s settings.Pressing one of the 2 buttons quickly displays the “title” of the measurement page to be displayed

NOTES AND OPERATING INSTRUCTIONS

DO NOT PRESS ANY OF THE KEYS while switching on the instrument (i.e. when connecting it to the auxiliary power supply).

Otherwise you may accidentally start the calibration procedure normally carried out at the factory which, if the instrument is connected to the system rather than to therespective calibration devices, could cause the instrument to be permanently not calibrated.

In the interest of safety, ALWAYS WAIT FOR THE INITIAL DIAGNOSTICSTO FINISH (scanning of the LEDS) before pressing any of the keys.

“S” instruments with threshold: The threshold relay is blocked for the first ten seconds after the instrument is switched on.The relay is “frozen” until you have finished configuring the settings.


15

OPERATION OF THE PROGRAMMABLE THRESHOLD (“S” models only). These models allow you to apply a max or min threshold as a percentage of the requiredsize, in relation toits intended full scale.

The threshold activation (threshold active) point is the condition “more than Th1 Val” if Th1 Sel = Hi; otherwise “less than Th1 Val” if Th1 Sel = LoThe threshold’s quiescent operating (threshold inactive) point is the condition “less than or equal to Th1 Val” if Th1 Sel=Hi; otherwise “more than or equal to Th1 Val”

if Th1 Sel=Lo.

The “active threshold” condition attempts to CLOSE the relay’s “N.O.” contacts and this occurs instantly unless there is the delay Th1 Dly if Th1 DD is “Off-On”The “inactive threshold” condition attempts to OPEN the relay’s “N.O.” contacts and this occurs instantly unless there is the delay Th1 Dly if Th1 DD is “On-Off”.

There are 2 cases whereby the output relay does NOT mirror the threshold condition. These are as follows:- During the first 10 seconds from starting up the instrument, when the relay is kept inactive to avoid unwanted operation while the measurements are stabilized, and- when the settings are being programmed on the keypad, it is kept at the same status at the time of starting the procedure, to prevent partial modification of the set-

tings from causing unwanted change to its status.Relay status is shown on the display at page “OUT”, together with the title of the size of the threshold selected in Th1 Src.Closing of the relay also determines flashing of the LED associated with the selected size (when applicable), providing the selected measurement page is not the one associated with the LED, in which case the LED light remains steady.

“RS485” Models: when Th1 Sel=OFF (threshold OFF), there is the option of controlling the relay directly by means of MODBUS commands to open and closeINSTANTLY, regardless of the Th1 Dly and Th1 DD settings. “Src=REM”(REMOTE) appears on the OUT page to indicate remote access of the relay.

For programming, press and hold the RIGHT-HAND button (for 4 seconds or more). The first page to appear when you are granted access to the programming mode isthe one of programmable values. Releasing the button will make the display flash (to indicate you are in programming mode) and the pages begin to scroll through slowly(one every 4 seconds or so), indicating the title and value of the current set-point. If you do not touch the button when you get the last page, normal operation is resto-red without saving any changes. To make a change, simply press one of the buttons when the required page appears, respectively:LEFT-HAND button = DECREASES the value; RIGHT-HAND button = INCREASES the value.At that point (after pressing the button) the display remains steady so you can check the modification and the value changes by one unit. If you have to modify a valuequite considerably, you can press and hold the button for more than 2 seconds to speed up the process. The longer you hold down the button, the faster you can scrollthrough the numbers (4 speeds). They are all “roll” values so when you get to the maximum permitted value you restarted from the minimum value, and vice versa. Whenyou have set the value as required, release the button and wait for over 4 seconds. The pages then continue scrolling and the modification is automatically saved.Modifiable pages then follow.

SCARICATORI CON LIMITATORE DI CORRENTE - GRUPPO C

Dopo anni di vendite, esperienze e prove è risultato evidente al mercato, che il problema più importante da risolvere negli scaricatori fosse quello di annullare o quantomeno ridurre almassimo il rischio di incendi dovuti al formarsi dell’arco fotovoltaico nel contatto del relè termico durante la commutazione. In aggiunta al fatto che recentemente le nuove normativestanno prendendo in considerazione questa problematica, Revalco ha deciso di sviluppare una nuova generazione di scaricatori adottando una diversa tecnologia; il relè termico ècollegato in linea con il varistore (MOV) e se la corrente aumenta, il secondo stadio di protezione reagisce scollegando il varistore stesso dall’alimentazione.

T.C.T.C.T.C.

1. Condizione 2. Come funziona 3. In caso di sovratensioniNormale di lunga durata - In caso di sovra tensioni fino al 50% della Uc, poiché interviene il limitatore di

corrente ( attorno a 10mA), il variatore (MOV) non viene danneggiato.

- In caso di sovra tensioni oltre il 50% della Uc, il limitatore di corrente interviene aproteggere il relè termico

- Questo nuovo sistema di protezione (brevettato) non permette la formazione dell’arcofotovoltaico; l’energia che quindi attraversa lo scaricatore è molto bassa (I2 x T)

Operative system “Open Loop (O/L)”The magnetic flux creaded by primary current IP, is concentradet in amagnetic circuit and measured on the open part of toroid by and Hallsensor. The signal exiting from this sensor is conditioned in the wayto represent exactly the primary current value.

This type of C.T. can be used as alternative to the shunts when high voltages are in the field and it is necesasry to have more higher galvanicseparations.

Function of sensor is based on “Hall effect” fisic principe:when a magnetic field is applied in a perpendicular way to a cable, atransverse voltage to the current flux direction is generated (Hall vol-tage).

The purpose of the shunt is to permit the passage of the current which exceeds the capacity of the instrument. The latter will therefore be supplied only with acurrent which corresponds to its capacity, thus avoiding the risk of damaging the measuring equipment. The shunts are resistances of very little value and forthis reason they are at times formed by conductors with a bar of limited length and substantial rectangular section. For heat dissipation several bars in parallelare used, terminating in two clamps with a large contact surface. Alongside the two current clamps there are a further two clamps which serve to connect theammeter.These clamps have lesser section as the current necessary for the instrument is much lower than that of the shunt. Infact , it is not so much a que-stion of the shunt being parallel with the instrument as the instrument deriving from the clamps of the shunt, of which it utilizes the drop in voltage, withdrawinga part of the current of the circuit, proportionate with the total current.

GENERALStandard application: 60 mV and 150 mVThe 60mV shunts are used with a maximum load of 0,25 ohm ; in the case of greater loads or long connection cables, the 150mV shunts shouldbe used.Standards require the following primary values: 1 - 1,5 - 2,5 - 4 - 6 - 10 - 15 - 25 - 40 - 60 - 100 - 150 - 250 - 400 - 600 - 1000 - 1500 - 2500 -4000 - 6000 - 10000 - 15000 A. Primary values different from the standard can be manufactured on request.To ensure the unit functions perfectly Revalco insists the following points are observed:

1. They can be fitted in either a horizontal or vertical position (if horizontal there is a greater dissipation of heat)2. The contact surface must be completely used.3. The contact surface must be clean; after connecting, cover with special grease.4. The screws and bolts must be perfectly tightened.5. The shunts must be sufficiently ventilated.

Due the fact that the shunts are not insulated, it is better to protect them against accidental contacts.
