Fig. 1a: Insulated connection Fig.1b: NOT insulated connection

On overmentioned figures (Fig.1a and Fig.1b) are shown connections to be used for pushbuttons but it is possible to connect: relay, TTL lines, transistors, etc. In order to light-on the LED emitters, internal to the opto-couplers, a voltage ranging from +12 to +28 Vdc must be supplied to each input. Opto-coupler’s electrical characteristics:

• Insulation: 3000 Vrms • Settling time: 18 µS ( max ) • Release time: 18 µS ( max )

2.12 Earth connection (CE norms) In order to obtain the maximum immunity to electrical disturbs, following are some recommendations:

• Power supply common must be connected to earth. • If AN401 plus is powered by a power supply separated from the rest of the machine,

connect the “EARTH” screw terminal to the nearest earth connection (avoid earth loops or earth connections disturbed by high power devices).

• When connecting signal lines from AN401 plus (analogue outputs, RS232 serial lines, etc) please remember that they are referred to earth, in order to avoid the creation of earth loops

• Best condition is obtained when all commons (signal and power supply) are connected to earth at the same point (star connection).

• Avoid wiring any input/output cable, directed to AN 401, with high power cables.

If the application is free from electrical disturbs, Earth connection may be avoided.

2.14.2 RS485 and RS422 line terminator resistor

MULTI DROP connections, like RS485 and RS422, require having a resistance applied at both ends of the communication line (if not yet present inside the connected devices); one is to be placed in parallel to the last AN401plus and one on the PLC or computer on the other end. AN401plus has no internal resistance for RS485 or RS422 but It can be applied under customer’s request. This resistor has to be 120 Ohm ¼ Watt. This resistance is to be applied solely on the last AN401plus of the serial net, in order not to lower, too much, the overall line impedance (fig.11).

3 Instrument setup

3.1 How to set parameters This chapter describes the sequence to be used to set AN401plus, as working parameters and It is valid for all of Its different menus. All different operational modes share the same sequence to set the desired values or parameters, or levels.

7.1 Peak function The peak function stores and displays the maximum value reached by transducer’s signal when the KEY4 rear contact is activated (see table 1) Key 4 rear contact has to be kept closed as long as peak value is to be displayed (see chapter 2.10). When this function is active, the leftmost LED dot under the minus sign is powered on. The stored peak value can be zeroed by: • Pressing C (ESC) push button on AN401plus front panel; • Closing KEY2 terminal on rear terminal panel (see chapter 2.10).

7.2 Hold Hold function freezes the measurement actually shown on the display, until it is disabled. All function measurements are freezed and it is activated by closing KEY 1 contact (see chapter 2.10). To de-activate this function open the contact

7.3 Protection AN401plus has a protection system that prevents not authorized personnel to tamper with the instrument settings, nor with programming menus. To activate protection, connect KEY3 as for chapter 2.10. When protection is enabled it is not possible to access to start-up programming menus. In order to apply authorized changes to the instrument, remove the connection on KEY3. Protection may be applied solely if an O5 I/O card is installed on slot C


-18 / 20-

8 DSENET serial protocol NOTE: for protocol compactness it was decided to use only one character to address an instrument. After the first ten numbers, address numbering continues with alphabet letters, thus A means 10, B means 11 and so on until Z that means 35.

8.1 “R” Command Command “R” allows to request, from a remote computer, the measure acquired by AN401plus within the active operating mode. The command argument defines which measures is requested to the instrument and is independent from the actual measurement function. Argument of the R command is an ASCII character and may assume the following values:

Command format @ ID R Index ( ind ) CR

Where:

ID = address of the connected AN401plus (in case only one AN401 is connected, by sending “?” the instrument will always reply). The identifier shall be a character in the set 0-9 or A-Z; ID can also be the character “?” if a message is to be sent to an instrument the identifier of which is unknown.

• R = read measure command. • Index = 1 digits numeric index indicating to AN401plus which measure is requested; see “Ind” column.

Note: RO means that the parameter is Read Only and cannot be modified by user. • CR = “Carriage Return” must close every message sent to the instrument and is represented by an ASCII

character. Ind Prot Parameter Symbol

0 RO Measured value A/D converter points VAL_AD 1 RO Filtered measured value A/D converter points VAL_ADF 2 RO Gross value in engineering units VAL_UMEC 3 RO Net value in engineering units

(GROSS–ZDYN) VAL_NZDYN

VAL_NTARE

5 RO Peak value (only for operating mode 7) with Kg engineering units VAL_ROTT 6 RO Peak value (only for operating mode 7) with N engineering units VAL_ROTTN

Example: Measured value, in A/D converter points, is requested with @?R0CR. Reply to command “R”: xxRyyyyyyyy Where: xx = sent command index ( Ind ): 2 digits. R = reply to command “R”: 1 digit. Yyyyyyyy = measured value: 8 digits.


-19 / 20-

8.2 Timestamp “r ” To obtain, from AN401plus, measured value with timestamp reference send command “r”. Timestamp is obtained from an incremental counter related to the measure performed by AN401plus and its value is ranging from 0 to 65535; when maximum is reached It restarts from zero. Working of “r” command is like “R” command (same command structure). Example: To request measured A/D converter value, send the following string: @?r0CR. Reply to command “r”: xxRyyyyyyyyzzzzz Where: xx = sent command index ( Ind ): 2 digits. R = reply to command “R”: 1 digit. Yyyyyyyy = measured value: 8 digits. zzzzz = timestamp: 5 digits.
