ducts, etc.), devices provided with big magnetos (big speakers, etc.),

locations subject to direct sunlight, rain, humidity, dust, mechanical

vibrations or bumps

• according to the safety legislation, the protection against electrical

parts must be ensured by a correct installation of the instrument; the

parts that ensure the protection must be installed so that you can not

remove them if not by using a tool.

1.3 Wiring diagram

With reference to the wiring diagrams:

• the serial port (by request) is the port for the communication with the

supervision system (through a serial interface, via TTL, with MODBUS

communication protocol) or with the programming key; the port must

not be used at the same time for the same purposes.

Additional information for electrical connection:

• do not operate on the terminal blocks with electrical or pneumatic

screwers

• if the instrument has been moved from a cold location to a warm one,

the humidity could condense on the inside; wait about an hour be-

fore supplying it

• test the working power supply voltage, working electrical frequency

and working electrical power of the instrument; they must correspond

with the local power supply

• disconnect the local power supply before servicing the instrument

• do not use the instrument as safety device

• for repairs and information on the instrument please contact Evco

sales network.

2 USER INTERFACE

2.1 Turning on/off the instrument

To turn on the instrument you have to supply it; to turn it off it is enough

to cut off the power supply.

If a lack of power supply arises when the count is running, the opera-

tion of the instrument to the restoration of the power supply will de-

pend on parameter t26.

2.2 Starting the count

• make sure no procedure is running

• provoke the effect you have set with parameter t11:

- if t11 = 0, press or activate input start

- if t11 = 1, press

- if t11 = 2, activate input start.

2.3 Stopping the count

• make sure parameter t17 has value 0

• provoke the effect you have set with parameter t12:

- if t12 = 0, press or activate input stop

- if t12 = 1, press

- if t12 = 2, activate input stop.

Otherwise:

• press 4 s.

2.4 Suspending/resuming the count

To suspend the count:

• make sure parameter t17 has value 2

• provoke the effect you have set with parameter t12:

- if t12 = 0, press or activate input stop

- if t12 = 1, press

- if t12 = 2, activate input stop.

If the count is suspended when load 1 (or load 2) is turned on, the load

status during the suspension will depend on parameter t24 (or t25):

- if t24 (or t25) = 0, the load will be turned off

- if t24 (or t25) = 1, the load will remain turned on.

To resume the count:

• provoke the effect you have set with parameter t11:

- if t11 = 0, press or activate input start

- if t11 = 1, press

- if t11 = 2, activate input start.

2.5 The display

If the count is running, the display will show the kind of count you have

set with parameter t15:

• if t15 = 0, the display will show the remaining time (count down)

• if t15 = 0, the display will show the elapsed time (count up).

If the count is suspended, the display will flash.

2.6 Silencing the buzzer in alarm

• press a button (the first pressure of the button does not provoke its

usual effect).

mento elettrico; conservare queste istruzioni con lo strumento per con-

sultazioni future.

1.2 Installazione

A pannello, con le staffe a scatto in dotazione (si vedano i disegni del

paragrafo 1.2 della sezione in Inglese).

Avvertenze per l’installazione:

• 59,0 è la profondità massima con morsettiere a vite

• 83,0 è la profondità massima con morsettiere estraibili

• lo spessore del pannello non deve essere superiore a 8,0 mm

• accertarsi che le condizioni di lavoro (temperatura di impiego, umidi-

tà, ecc.) rientrino nei limiti indicati nei dati tecnici

• non installare lo strumento in prossimità di fonti di calore (resistenze,

condotti dell’aria calda, ecc.), di apparecchi con forti magneti (grossi

diffusori, ecc.), di luoghi soggetti alla luce solare diretta, pioggia, umi-

dità, polvere eccessiva, vibrazioni meccaniche o scosse

• in conformità alle normative sulla sicurezza, la protezione contro even-

tuali contatti con le parti elettriche deve essere assicurata mediante

una corretta installazione dello strumento; tutte le parti che assicurano

la protezione devono essere fissate in modo tale da non poter essere

rimosse senza l’aiuto di un utensile.

1.3 Collegamento elettrico

Si vedano i disegni del paragrafo 1.3 della sezione in Inglese.

Con riferimento agli schemi elettrici:

• la porta seriale (su richiesta) è la porta per la comunicazione con il

sistema di supervisione (attraverso un’interfaccia seriale, via TTL, con

protocollo di comunicazione MODBUS) o con la chiave di program-

mazione; la porta non deve essere utilizzata contemporaneamente

per i due scopi.

Avvertenze per il collegamento elettrico:

• non operare sulle morsettiere utilizzando avvitatori elettrici o pneuma-

tici

• se lo strumento è stato portato da un luogo freddo a uno caldo, l’umi-

dità potrebbe condensare all’interno; attendere circa un’ora prima di

alimentarlo

• accertarsi che la tensione di alimentazione, la frequenza e la potenza

elettrica operativa dello strumento corrispondano a quelle dell’alimen-

tazione locale

• disconnettere l’alimentazione prima di procedere con qualunque tipo

di manutenzione

• non utilizzare lo strumento come dispositivo di sicurezza

alla rete di vendita Evco.

2 INTERFACCIA UTENTE

2.1 Accensione/spegnimento dello strumento

Per accendere lo strumento è necessario alimentarlo; per spegnerlo basta

togliere l’alimentazione.

Se si manifesta un’interruzione dell’alimentazione quando il conteggio

è in corso, il funzionamento dello strumento al ripristino dell’alimenta-

zione dipenderà dal parametro t26.

2.2 Avvio del conteggio

• assicurarsi che non sia in corso alcuna procedura

• provocare l’evento stabilito con il parametro t11:

- se t11 = 0, premere o attivare l’ingresso start

- se t11 = 1, premere

- se t11 = 2, attivare l’ingresso start.

2.3 Interruzione del conteggio

• assicurarsi che il parametro t17 sia impostato a 0

• provocare l’evento stabilito con il parametro t12:

- se t12 = 0, premere o attivare l’ingresso stop

- se t12 = 1, premere

- se t12 = 2, attivare l’ingresso stop.

In alternativa:

• premere per 4 s.

2.4 Sospensione/ripresa del conteggio

Per sospendere il conteggio:

• assicurarsi che il parametro t17 sia impostato a 2

• provocare l’evento stabilito con il parametro t12:

- se t12 = 0, premere o attivare l’ingresso stop

- se t12 = 1, premere

- se t12 = 2, attivare l’ingresso stop.

Se il conteggio viene sospeso quando il carico 1 (o il carico 2) è acceso,

lo stato del carico durante la sospensione dipenderà dal parametro t24

(o t25):

• se t24 (o t25) = 0, il carico verrà spento

• se t24 (o t25) = 1, il carico rimarrà acceso.

Per riprendere il conteggio:

• provocare l’evento stabilito con il parametro t11:

- se t11 = 0, premere o attivare l’ingresso start

- se t11 = 1, premere

- se t11 = 2, attivare l’ingresso start.

2.5 Il display

Se il conteggio è in corso, il display visualizzerà il tipo di conteggio stabi-

lito con il parametro t15:

• se t15 = 0, il display visualizzerà il tempo residuo (count down)

• se t15 = 1, il display visualizzerà il tempo trascorso (count up).

Se il conteggio è sospeso, il display lampeggerà.

2.6 Tacitazione buzzer in allarme

• premere un tasto (la prima pressione del tasto non provoca l’effetto

associato).
