Modalità operative

Il Dual controller può funzionare nelle seguenti modalità:

LOCAL

REMOTE I/O (input/output)

SERIAL.

Nella modalità LOCAL tutti i comandi sono attivati dal pannello frontale.

Nella modalità REMOTE I/O tutti i comandi sono attivati da un personal computer remoto collegato tramite il connettore di input/output collocato sul pannello posteriore.

Nella modalità SERIAL tutti i comandi sono attivati da un personal computer esterno collegato tramite l’interfaccia seriale

RS 232-422-485.

NOTA La modalità operativa selezionata viene memorizzata dal sistema e quindi al ripristino della tensione in seguito alla sua caduta, il controller Dual ritornerà nella modalità operativa nella quale era al momento dalla caduta di tensione.

NOTA Quando viene selezionata una qualsiasi modalità operativa, il sistema accetterà solamente i comandi della relativa modalità però è in grado di visualizzare informazioni e acquisire segnali e dati contemporaneamente da tutte le interfacce.




L’unità è progettata per funzionare nelle seguenti modalità:

modalità START modalità PROTECTED

Nella modalità START il controller fornisce tutta la potenza, indipendentemente dalle condizioni della pompa, fino a raggiungere la corrente di corto circuito. Questa modalità di funzionamento deve essere utilizzata per avviare la pompa ad alta pressione.

Nella modalità PROTECTED il controller limita la corrente in uscita e spegne l’alta tensione quando il valore di corrente supera la corrente di soglia per oltre 0,2 secondi.

In condizioni di normale funzionamento, questa è la modalità preferita in quanto, in caso di guasto alla pompa ionica o al cavo causato da corto circuito o alto carico, l’alta tensione si spegnerà.

Fare riferimento “Technical Information” per informazioni dettagliate sulle modalità operative.

Modalità operativa Step

La modalità Step deve essere scelta alfine di ottimizzare le prestazioni della pompa e consentire le letture a pressione molto bassa senza influenzare la corrente di dispersione.

Nella modalità Step il controller Dual sceglie la tensione in uscita più appropriata secondo la pressione all’interno della pompa (vedere la figura seguente).

Betriebsarten

Der Dual-Controller kann in den folgenden Modi arbeiten:

LOKAL

FERN-E/A (Ein-/Ausgang)

SERIELL.

Bei LOKAL werden alle Befehle über die vordere Schaltafel gegeben.

Bei FERN-E/A kommen alle Befehle von einem abgesetzten Computer

über den E/A-Stecker auf der hinteren Schalttafel.

Bei SERIELL kommen alle Befehle von einem externen Computer, der über eine serielle Schnittstelle RS 232-422-485 angeschlossen ist.

HINWEIS Das System speichert, welche Betriebsart gewählt ist, und setzt daher bei

Wiederanlauf nach einem Stromausfall mit der Betriebsart fort, die vor der

Unterbrechung gewählt war.

HINWEIS Wenn eine Betriebsart gewählt ist, nimmt das System nur die in diesem Modus gültigen Befehle an. Es kann aber gleichzeitig Informationen anzeigen und

Signale und Daten von allen Schnittstellen entgegennehmen.



Bedienung

2

Der Controller kann in folgenden Betriebsarten betrieben werden:

 START-Modus

 PROTECTED-Modus

In der Betriebsart START arbeitet der Controller unabhängig vom

Pumpenzustand bei voller Leistung bis zum voreingestellten

Kurzschlußstromwert. Diese Betriebsart muß zur Steuerung von

Pumpen bei Hochdruck gewählt werden.

In der Betriebsart PROTECTED werden der Stromausgangswert des

Controllers begrenzt und die Hochspannung abgeschaltet, sobald der

Strom den voreingestellten Schwellenwert länger als 0,2 Sekunden

überschreitet.

Bei Normalbetrieb ist dies der bevorzugte Modus, da bei Versagen von Ionenpumpe oder Kabel wegen Kurzschluss oder Überlastung der

Starkstrom abschaltet.

Detaillierte Angaben zu den beiden Betriebsarten finden sich im

Anhang “Technical Information".

Stufenbetrieb

Stufenbetrieb muss gewählt werden, um die Pumpenleistung zu erhöhen und bei sehr niedrigem Druck ohne Einfluss des Leckstroms ablesen zu können. Im Stufenbetrieb wählt der Dual-Controller die beste Ausgangsspannung entsprechend dem Pumpeneingangsdruck

(siehe die folgende Abbildung).



Bedienung

Abbildung 7 Änderung der Ausgangsspannung in Funktion des Drucks

Modes de fonctionnement

Le Dual contrôleur peut fonctionner dans les modalités suivantes:

LOCAL

ELOIGNE I/O (input/output)

SERIEL.

Dans le mode LOCAL toutes les commandes sont activées par le panneau frontal.

Dans le mode ELOIGNE I/O toutes les commandes sont activées par un ordinateur éloigné relié par l’intermédiaire d’un connecteur de input/output placé sur le panneau postérieur .

Dans le mode SERIEL toutes les commandes sont activées par un ordinateur externe relié par l’intermédiaire d’une interface sérielle

RS 232-422-485.

NOTE La modalité opérationnelle sélectionnée est mémorisée par le système et donc dès le rétablissement de la tension suite à sa chute, le contrôleur Dual reviendra

à la modalité opérationnelle où il était au moment de la chute de tension.

NOTE Lorsque une modalité opérationnelle est sélectionnée, le systènme acceptera uniquement les commandes de la modalité relative mais il est en mesure de visualiser des informations et d’acqyérir des signaux et des données contemporairement de toutes les interfaces



Utilisation

L’unité est projetée afin de fonctionner dans les modalités suivantes:

 mode START

 mode PROTECTED

Dans le mode START le contrôleur fournit toute la puissance, indépendamment des conditions de la pompe jusqu’à atteindre le courant de court circuit. Cette modalité de fonctionnement doit être utilisée pour actionner la pompe à haute pression.

Dans le mode PROTECTED le contrôleur limite le courant à la sortie et éteint la haute tension lorsque la valeur du courant dépasse le seuil pendant plus de 0,2 secondes.

Dans des conditions de fonctionnement normal, on préfère utiliser cette modalité puisque, en cas de panne de pompe ionique ou câble causée par un court circuit ou une haute charge, la haute tension s’éteint.

Se référer à l’appendice "Technical Information" pour des informations détaillées sur les modalités opérationnelles.

Mode de fonctionnement Step

Le mode Step doit être choisi pour améliorer les performances de la pompe et effectuer des lectures à une pression très basse sans influer sur le courent de dispersion. Dans le mode Step le Dual contrôleur choisit la tension en sortie la plus convenable selon la pression dans la pompe (voir le dessin suivant).

Operating Modes

The Dual controller can work in the following operating modes:

LOCAL

REMOTE I/O (input/output)

SERIAL.

In the LOCAL mode all the commands are given through the front panel.

In the REMOTE I/O mode all the commands are given from a remote computer through the input/output connector located on the rear panel.

In the SERIAL mode. All the commands are given from an external computer through the RS 232-422-485 serial line.

NOTE The selected mode of operation is stored by the system and therefore even if a power failure occurs, when the power is restored, the Dual controller will return to the mode of operation that it was in prior to the blackout.

NOTE When any one mode of operation is selected, the system will only accept the commands of that related mode while being able to simultaneously display information and acquire signals and data from all the interfaces.




The unit is designed to work in the following modes:

 START mode

 PROTECTED mode

In the START mode the controller provides all the power regardless of the pump’s conditions, until reaching the short circuit current.

This mode of operation must be used to start the pump at High

Pressure.

In the PROTECTED mode the controller limits the output current and switches off the high voltage when the current exceeds the threshold current for more that 0.2 seconds.

In normal operation, this is the preferred mode, as any failure of the ion pump or cable due to short circuit or high load will cause the high current to switch off.

Refer to the appendix entitled “Technical Information" for detailed information on the modes of operation.

Step Mode of Operation

The Step mode has to be chosen in order to increase the performance of the pump and to read at very low pressure without influence of leakage current.

In Step mode the Dual controller chooses the best output voltage according to the pressure into the pump (see the following figure).

Figure 7 Output voltage change-over vs pressure

Powering On the Controller from the Front Panel

(LOCAL Mode)

NOTE To switch on the H.V. the external interlock must be closed (connector inserted).

If no external connection is made, insert the interlock-closing jumper that are provided with the unit.

Proceed as follows to power on the controller and enable the voltage on the H.V. connectors:

Insert the cable from the pump and the interlock loopback pin of the H.V. cable into the related connectors on the rear panel.

Set the power switch on the rear panel to the ON position.

Set the ENABLE HV switch on the front panel to the ON position.

Press the HV 1/2 ON/OFF buttons (ON LED lit).



Maintenance

NOTE With only one H.V. circuit installed both rows on the display are dedicated to pump number one, while with two circuits installed each row is dedicated to a different pump.

Starting the Pump

To start the pump, press the corresponding HV ON/OFF button; the

ON LED will come on.

Stopping the Pump

To stop the pump press the corresponding HV ON/OFF button; the

Dual Controller Description


The Dual Controller base is available in versions which differ in the factory set input voltage and in the internal configuration.

Models 929-7000/1/2/3 and 929-7008/09/10/11 require an input voltage from 100 to 120 Vac, frequency of 50/60 Hz,

Models 929-7004/5/6/7 and 929-7012/13/14/15 require an input voltage from 200 to 240 Vac, frequency of 50/60 Hz.

The models are provided with a front panel with an LCD alphanumeric display to indicate the operating conditions/parameters of the Ion pump and a keyboard, and a rear panel with input/output connectors.

The figure below shows the Dual controller.

The controller unit can be operated via:

Front panel switches

Remote signals via rear panel connectors

RS 232/485/422 serial link (option).

A maximum power of 420 W is delivered simultaneously on the two channels, while a maximum power of 400 W is delivered on a single channel. If a total of more than 420 W is requested, the power delivered by the controller is distributed by means of an appropriate algorithm resident in the DSP.

The Dual is a power supply designed to meet a wide range of requirements.

It is a compact unit, specifically designed to operate ion pumps with both positive and negative polarity from 20 l/s to 500 l/s and up to

400 W output power.

5




The unit is programmed with pre-defined pump settings and the user can tailor for his purpose the voltage, short circuit current, maximum power, pressure versus current curve for one more pump not included in the pre-defined type of pumps. Using a patented operation principle, the controller is capable of reading pressure down to the 10 -11 Torr range, while optimising the pumping speed in the entire operating range.

Algorithm for the Distribution of the Available

Power

During the start-up phase, priority is given to the pump that is started first. Consequently, this pump is provided with all the power required while the second pump is provided with the power that remains.

Upon completion of this start-up phase the controller, if necessary, will proportionally distribute the available power according to the maximum power that the pumps can require.

If more than 420 W are requested, to reach a stabilized condition the controller will act on the pump power supply voltage so as to maintain constant the power delivered.

If one of the two pumps enters into the short circuit range the start phase is resumed. In this case, priority is assigned to the pump that is in the short circuit range; if both pumps are in this range, priority is assigned to the one that entered this range first.

If the HV output voltage drops below 150 V with a current equivalent to 80% of the short circuit value for a time frame exceeding 5 seconds, the related output is disabled and the following message is displayed: HV (X) ERROR SHORT CIRCUIT.

In other words, program the conversion table from current to press.

Store the pressure value for other three pump current values (10 μa,

10 mA, 400 mA).

Since an exponential value is displayed, press the CHANGE button to change the mantissa of the pressure and then confirm by pressing the

ENTER button; now press the CHANGE button to modify the exponent and then press ENTER to confirm the selection made.

Storing these values allows the Dual to convert the pump current into pressure values even if the operating voltage is different from 5000 V.

The correction factor due to the different voltage is automatically applied by the Dual software in order to obtain a continuous correct pressure reading.

Serial Interface

5


General

After having described the connector and the pinouts in the different configurations, this section provides information on Dual controller’s serial interface. In particular, bear in mind that compatibility with the existing protocols on the MultiVac (Binary and ASCII) has been maintained as far as the data format and different commands are concerned. Furthermore, a new protocol called MultiGauge

Compatible is introduced. It derives from the Mini B/A Eye Sys specifications and implements the data format above all, while the majority of the commands are new.

General Definitions of the Hardware Protocol

The Dual controller implements the following data exchange protocols:

Tab. 16

Binary

Ascii

MultiGauge

Compatible

Protocol

Derived from the MultiVac’s binary protocol

Derived from the MultiVac’s ASCII protocol

Derived from the protocol used for the MiniGauge Eyesys

With respect to the three native protocols, compatibility is guaranteed at format level (header, terminator, checksum, etc.), while the different commands are implemented in compliance with the characteristics of the Dual controller.




Hardware Signals Management

The RX, TX and GND signals are present on the data exchange line.

There is no flow control implemented through RTS/CTS and the DTR and DSR signals are not handled.

The RS232, RS422 and RS485 physical interfaces are implemented.

NOTE The RS485 requires software addressing and therefore a binary protocol is needed.

Transmission Format and Timeout

The serial data transmission parameters are listed below:

Tab. 17

Start bit

Stop bit

Data bit

Parity

1

1

8

None, Odd, Even

1 All the baud rates indicated are supported; the default rate is 9600.

Data exchange is performed in the Half-Duplex mode.

To guarantee a synchronized data flow and to prevent conflicts, the timings indicated in the table below must be respected:




Tab. 18

Treset

Tmin

Tmax

Maximum delay between consecutive bytes of the same data packet. The controller can reinitialize reception if this time frame expires without data exchange.

Minimum time frame before a reply can be initiated. The controller’s reply message cannot begin until the expiry of this time frame, which is initiated at the end of the Host message.

Maximum time frame within which a reply can be given. The controller’s reply message cannot begin until the expiry of this time frame, which is initiated at the end of the Host message.

Minimum time frame for query transmission.

2 byte time 2

4 msec

100 msec

Tquery

Tresponse Minimum time frame for reply transmission. nº byte x byte time nº byte x byte time

2 byte time Trelease Maximum time frame within which the RS485 line can be freed.

Within this time frame the controller must free the serial line upon completion of reply transmission. Such time out is relevant in the RS485 mode only.

2 Equivalent to the transmission time of a single byte at the selected baud rate and assumes the following values:

8.33 msec at 1200, 4.16 msec at 2400, 2.08 msec at 4800, 1.04 msec at 9600.

A data exchange session will therefore assume the timing shown in the following figure:

5

Figure 30 Timing




Data Exchange Error Management

The following data exchange errors are handled (during reception by the controller):

Tab. 19

Error Type

Overrun

Possible Cause

Problems with the Dual controller’s data exchange driver

Frame error Line noise, incorrect baud rate or data corruption

Checksum error Data corruption (not on the MultiGauge Protocol)

Full buffer

Bad header

Time-out

Too many bytes or data corruption

Inexistant or incorrect header

Unrespected time out (Treset)

When a data exchange error occurs, the Dual controller does not react in any way to the command received but replies with an NACK message except in cases when an RS485 serial line is used.

If an unrecoverable error (crash error) occurs on the Dual controller, the serial line will not be able to handle any type of data exchange.



Software Protocol

5


The Dual controller automatically detects the type of software protocol used by analyzing the header and provides its related reply.

The three protocols have equivalent data fields which comply with the following formats:

Tab. 20

Status

No. of Bytes.

1

String

7 n

Description

“?” (3Fh3) performs reads on the Dual controller

“0” (30h) = false = off,

“1” (31h) = true = on 5 represented in BCD4 on 5 digits

(always positive)

Like the integer type, but with meanings associated to the number’s single bits

“x.xEsxx” where x is BCD digits, E is the 45h character and s is the (“+” o “-“ sign

Sequence of n characters included within the 20h and 7Fh range

3 the “h” notation following a number indicates that the number is expressed in hexadecimal format

4 BCD: the number is represented by digits included within the “0” and “9” range (ASCII 30h - 39h).

5 Status can also assume values greater than “1”.

The commands have a read and a write mode. By specifying the type of read operation being performed, the Host queries the Dual controller which in turn replies in a format compliant with the command sent. As long as a write operation can be carried out, the write and read formats for the same command coincide.




The write modes will have the following possible replies:

ACK command correctly received and executed: run a query to check that the value has been written

(typical for High Voltage/Gauge power on/power off)

(“!” 21h) (see Protocol Errors)

Value command received and executed: the value is immediately returned in the same format of the write command (the query is not required).

The commands are associated to the channel which is specified in the

Channel field. The following table indicates the values that can be assigned in this field:

Tab. 21

Value Channel Description

“0” 30h No channel The command does not act on any specific channel but overall on the entire Dual controller

(e.g. firmware version read)

“1” 31h High Voltage 1 The command acts on a Channel 1 corresponding to the

High Voltage 1 module

“2” 32h High Voltage 2

“3” 33h

“4” 34h

“5” 35h

Gauge1

Gauge2

Serial

The command acts on a Channel 2 corresponding to the

High Voltage 2 module


MiniGauge 1 module


MiniGauge 2 module

The command acts on a Channel 5 corresponding to the Serial Communication module


NOTE



5

Furthermore, the physical measurements visible from the serial line will always have the related unit of measure indicated. This applies, above all, for pressure measurements that are not subject to the settings made on the Dual controller.

The RS485 mode is normally used in a data exchange network where the software addressing of the different nodes connected (maximum 32) is only made possible by means of the binary protocol. Therefore in the RS485 mode, the Dual controller will only recognize the binary protocol and will ignore any data exchange performed using the ASCII and MultiGauge Compatible Protocol.

In the Remote I/O mode, only the commands present on the digital outputs of the Remote I/O (Fixed/Step, Local/Remote, Start/Protect, pump on/off) are read-only active.

The write commands are enabled in the automatic mode only. In addition, the remote mode cannot be selected during a menu editing phase using the front panel.

Specific Protocol Settings

5


Ack/Nack Mode

Setting the appropriate bit via the Serial Property command enables the Dual to transmit the Acknowledge (06h) flow control.

Write Reply

Setting the appropriate bit via the Serial Property command enables the Dual to provide a reply after a write command with the typical read communication.

Example:

HV power on: reply (HV on): reply (HV not on):

[header]A011[chk]

[header]A011[chk]

[header]A010[chk]

Multiple Commands

Setting the appropriate bit via the Serial Property command enables multiple command function. With this function, it is possible to transmit to the Dual query command sequences within the same data packet, by linking 1 up to 6 query commands to the command-

channel-data fields.




In the case of multiple commands, the data format has the following limitations:

Format errors in only one of the commands sent will cause an error with the entire packet

With the multiple command it is not possible to read the strings

(eg., software version)

Multiple commands are not enabled with the Lexington protocol

The query has to be as follows:

[command][channel][data query (?)][8 byte space] [next command]….[chk]

The reply data are collected in 12-byte packets as follows:

[command][channel][data answer][n space]

Following is an example of a multiple command where a space is indicated with the letter s: query: HV1 state, HV2 state, Vmax ch1, Vmax ch2:

[header]A01?ssssssssA02? ssssssssH01? ssssssssH02?ssssssss [chk] reply HV1 off, HV2 on, Vmax ch1 5000V, Vmax ch2 7000V

[header]A010ssssssssA021ssssssssH0105000 ssssssssH0207000ssss[chk]

Automatic Serial Mode

Setting the appropriate bit via the Serial Property command enables the automatic Serial Mode function. When the Dual receives a serial write command, it automatically switches to the Serial Mode state in which it can accept the serial command. If a read command is received instead, the operating mode remains unaltered.

If this bit is not set, the serial write command is not accepted (the reply will be an error code) and the Dual will remain in the selected operating mode (either Local or Remote I/O).




5

Compatibility with MultiVac

The Binary and ASCII protocols are implemented, for the most part, by the protocol used on the MultiVac but are characterized by certain differences consisting of new features and certain Dual controller structural variations with respect to the MultiVac.

The new features implemented are the following:

Multiple commands

Ack/Nack mode

Reply on write mode

Even and odd parity management

New serial commands

MiniGauge serial commands

Configuration serial commands.

The structural variations mostly concern the command set and formats. In particular, it is not possible to make up for the differences resulting from the hardware implementation such as the presence of the HV microcontroller, the Remote I/O, the MiniGauge options and the configuration commands.

NOTE These differences can be limited by using the Serial Property command to set the full compatibility MultiVac bit to 1. Its purpose is to render compatible the already existing programs but introduces certain limitations that advise against its use with new applications. In the case of a full compatibility MultiVac, the following settings will also be made:

Multiple command disable

Reply on write disable

Lexington protocol exclusion

The following table lists the incompatibilities that remain even though full compatibility MultiVac has been set:

The following commands, therefore, remain unchanged:

Vmax, Imax, Pmax, Iprotect, Vstep1, Istep1, Istep2, SetPt1, SetPt2,

P100nA, P10uA, P10mA, P400mA.

The part relating to the Gauges will not guarantee compatibility since the Gauge cards implemented have been changed with respect to

MultiVac.

In addition, configuration commands were unavailable on the

MultiVac.
