6 General Decription We deigned the INTUITIVE-S to decode and diplay ASCII erial data from RS232, RS422, RS485 or 20mA TTY data port. You can elect your preferred data type by way of rear witch etting. The main purpoe of the INTUITIVE-S i to diplay numeric data coming from meaurement ytem, and from thi data it can give alarm output, caled analogue output and erial data retranmiion. It can alo accept a limited range of alphabetic character, but won t provide alarm or analogue output unle the data i purely numeric.the diplay can be et with up to 254 different addree for ue in multi-drop network. It can alo extract a ection of numeric data from a complex datatring, uing tring editing feature. The front panel ha a 6 digit, 7 egment window for diplaying the decoded numeric data. It allow decimal point and minu ign character to be included and ha 4 alarm annunciator to how the tatu of each alarm relay. Max. AL1 In normal operation, with the lockout witch ON, the LED will flah in repone to valid incoming data. DIGIT TARE MAX / MIN SPECIAL 0% ANALOG 100% ANALOG RESET ALARMS OK AL2 AL3 AL4 Min. Unit of meaure window All programming adjutment are made via the front panel puhbutton, which ue LED annunciator to how which etting i being altered at any time. A clear protective window i provided, behind which you can fit one of our Unit-of-Meaure label, to identify the reading a Kg, or Deg. C, or Bar, etc. A lockout witch on the rear of the meter afeguard your configuration etting in non-volatile memory, which ha a 10 year guaranteed retention period. If the lockout witch i not activated, the diplay ha no parity teting or addre election. Character will be diplayed in real time a they arrive, o long a they match the baud rate which wa et via the front panel. The diplay can be made to flah, and ha 6 level of electable brightne. 3

7 Getting Started Firt, pleae check that the diplay will uit all the requirement of your application. Page 4 ha ome important warning - pleae check that all warning are covered. Next, et the witche on the back of the diplay to uit the data type you ll be uing. See page 6. Check that your panel cutout i correct, 92mm wide, 45mm high. You mut fit the meter in a protective encloure for intallation cla II ervice. Remove the 2 crew holding the U clamp at the rear of the cae. Slide the meter into the cutout and re-fit the U clamp and crew. Tighten the crew jut enough to hold the meter firmly in place. Connect the ignal and power cable, to the appropriate crew terminal connector. See page 6 to check that you are uing the correct terminal. Apply power, and confirm that the meter illuminate all egment for a few econd and then how the oftware verion SEr. 1.X briefly (The X numeral depend on verion). The lockout witch hould be OFF to allow you to change the meter etting. Set baud rate, addre, parity etc. to uit your ytem. Now, if you end an ASCII character of the correct baud rate, the meter hould repond. With the lockout OFF, the meter will repond immediately to each valid character received, ueful for initial diagnotic. However, to operate properly, and to afeguard your etting you mut et the lockout witch to ON. The TERMINAL acceory in Window i a imple and ueful application for generating erial data. It can be ued to check mot feature of the INTUITIVE-S Here how to connect your INTUITIVE to a PC RS232 port...

If a parity error occur, the diplay will how Err P until valid data arrive, or until the diplay time-out. Data with parity error won t update or affect analogue O/P or alarm tatu. Note that the parity etting applie to RECEIVED data only. The output data (if a Serial Data O/P option board i fitted) will alway be in the following format : 1 tart bit, 8 data bit, no parity bit, and will be at the ame baud rate a the received data. 9

13 IDLE timeout etting. The IDLE TIMEOUT i a ueful feature which can be ued to how when data input ha been lot, or can be ued to permanently diplay the lat valid data tring which wa decoded - ueful if data arrive infrequently, for example from an operator manual entry keyboard. All received data will be lot if you witch the diplay off. After you pre OK in the parity etting ection, the diplay will how either IdL.no or IdL. 3 or IdL.10 or IdL.30 or IdL.60 DIGIT TARE SPECIAL MAX / MIN 0% ANALOG 100% ANALOG RESET ALARMS OK Max. AL1 AL2 AL3 AL4 Min. IdL.no mean the diplay will how the lat received data permanently. IdL. 3 mean the diplay will how if no data arrive for 3 econd IdL.10 mean the diplay will how if no data arrive for 10 econd IdL.30 mean the diplay will how if no data arrive for 30 econd IdL.60 mean the diplay will how if no data arrive for 60 econd Chooe one of thee option uing the UP/DOWN button. Pre OK to ave your choice. Note: When timeout occur, the diplay how , all alarm go inactive, analogue output goe to 0% and the erial output tranmit one tring of <CR> and i then idle until new valid numeric data i received and diplayed. Alo, nothing will happen if you activate the TARE or PEAK/VALLEY input. The default etting i IdL.no 10

14 Data edit LOSE etting. If you have a complex data tring, and only want to diplay a certain part of it, you can ue the LOSE etting to ignore(loe) a defined number of data character. The character we loe will be between the <CR> character and the data of interet. For example, if your tring i <STX>7768*2505_TY456<CR><ETX> and you only want to how the 2505 character, you ll want to loe _TY456 which i a group of 6 character.

After you pre the OK button after the Data edit LOSE etting, the diplay will how dsp.3 or dsp.4 or dsp.5 or dsp.6 (dsp mean diplay ) You can elect any one of thee choice if you pre the UP or DOWN button. So, we can chooe to diplay 3, 4, 5 or 6 digit. In our example above, we would chooe dsp.4 Pre OK when you want to ave your choice. An embedded decimal point in t conidered a a character, but a minu ign i conidered a a character. The default etting i dsp.6 12

16 String Terminator etting. Thi feature i ueful when the data tring i complex and include an eaily identified datum character which can be ued a a reference for the data to be diplayed.the mot common tring terminator i the CARRIAGE RETURN, (commonly identified a ASCII HEX 0d) Conider a tring uch a: :<STX>55555_ABTOL_NETT_386.9Kg_SER02345<CR><ETX> where the data you wih to diplay i and where the urrounding data could vary in length. You could pecify the letter K a being the datum character, if it alway occur immediately after the deired diplay character and nowhere ele. The letter K i repreented a 4B hex in ASCII. Here how we would et the letter K a the tring terminator... After preing OK in the dsp.xx etting, the indicator will how C.r. XX where XX i the HEX code of an ASCII character which you can chooe to ue a a tring terminator, or carriage return. DIGIT TARE SPECIAL MAX / MIN 0% ANALOG 100% ANALOG RESET ALARMS OK Max.

17 Decimal point etting. Thi feature i only of interet if you are etting the meter analogue output or Alarm relay option. If you ue either of thee option, you mut firt know if there i a decimal point in the incoming data, and if o, where it i placed. It mut be fixed, not floating, or you will get unexpected reult. If the data i ent to 2 decimal place, you mut et 2 decimal place in thi variable. Here how you et the decimal point poition... After you pre the OK button in the String Terminator etting, you ll ee a diplay of dddddd, and there will be a decimal point lit too. DIGIT TARE SPECIAL MAX / MIN 0% ANALOG 100% ANALOG RESET ALARMS OK Max. AL1 AL2 AL3 AL4 Min. If you pre the UP or DOWN button, you will ee that the decimal point move poition. Keep moving the decimal point until it matche the decimal point poition of the tranmitted data. When you ve choen your decimal point poition, pre OK to ave the etting. The default etting i dddddd. 14

18 Peak and Valley detection The meter ample the input data and compare the numeric ample to previou peak or trough and update the peak or valley memory if required with the new value. You can view the tored peak and valley, either by the front panel puhbutton or by external contact cloure. Peak i annunciated on the diplay by the upper alarm LED bar illuminating (identified a Max. on the front panel). Valley i annunciated on the diplay by the lower alarm LED bar illuminating (identified a Min. on the front panel). The election of actual reading, peak and valley i equential.

20 Alarm Configuration & Adjutment We et our alarm output for failafe operation (where contact open on alarm or when power i lot to the meter) with jumper et for OPEN CONTACTS and DE-ENERGISE on alarm. If you want to change thi action, firt remove power from meter, including any power which might be preent on the alarm output circuitry. Select relay output contact tatu, when relay are de-energied (power removed from meter) by placing thee jumper... Open Contact Cloed Contact Look on the top and bottom urface of the cae, near the rear. You will ee two mall crew, one on each urface. Energie De-energie Alarm Setting AL1 AL2 AL3 AL4 Energie De-energie Energie De-energie Energie De-energie Remove both crew. Now, clip off the front bezel and lide the meter aembly carefully out via the front of the cae and eparate the upper and lower card. To re-aemble, revere thi procedure, and be careful to enure that the upper board i properly plugged into the lower board connector. If you pre the ALARMS button momentarily you can view each alarm etting (each pre will illuminate in turn AL1, AL2, AL3 and AL4 annunciator) To change alarm etting, elect the alarm you wih to change a above, then pre ALARM key for more than 3 econd. You will firt ee the preent alarm action, a HI, LO or off. You can alter thi by preing the UP or DOWN button. Pre OK to ave your choice.next, you will ee the actual alarm level, with one digit brighter than the other. Thi may be changed in value uing the UP/DOWN button, and the digit may be elected uing the DIGIT SELECT puhbutton. The HYSTERESIS value i identified with a Hy prompt, and may imilarly be amended to the deired value. The hyterei value i directly related to your meaurement, o, for example, if you have a high alarm, et to 500, and et the hyterei value to 7, the alarm will occur when the meter reading rie above 500, and will reet when the meter reading fall to

21 Analogue O/P Configuration & Adjutment The analogue output board i et for either -5 to +5V, 0-10V or 4-20mA and will need no adjutment other than etting the reading value to generate 0% and 100% of output, uing the front panel puhbutton. -5 to 0 to +5V 0-10V 4-20mA Thi potentiometer may not be fitted on all board. It i only to be adjuted in the factory To change a range, for example from 0-10V to 4-20mA, you mut repoition ome jumper a hown above, and adjut the zero and pan potentiometer to get the correct output level at 0% and 100%. Look on the top and bottom urface of the cae, near the rear. You will ee two mall crew, one on each urface. Remove both crew. Now, clip off the front bezel and lide the meter aembly carefully out via the front of the cae and eparate the upper and lower card.(unplug the board from the hot to change jumper poition). Make any adjutment a required, and eal the potentiometer with varnih. To re-aemble, revere thi procedure, and be careful to enure that the upper board i properly plugged into the lower board connector. Analogue O/P Setting Firtly, you ll need to et the rear lockout witch to OFF (down) 1) Pre the OUTPUT button for 3 econd 2) You hould ee the 0% O/P LED flah 3) Set the diplay to the reading value at which you wih to generate 0% Output by uing DIGIT SELECT & UP/DOWN 4) When the diplay i correctly et, pre OK 5) Now you hould ee the 100% O/P LED flahing. 6) Set the diplay to the reading value at which you wih to generate 100% Output by uing DIGIT SELECT & UP/DOWN 7) When the diplay i correctly et, pre OK 8) Set the lockout witch to ON (up) when finihed, to ave your etting.

25 Data Inverion Facility We have found that ome ytem ue inverted data polarity, particularly in 20mA TTY application. If thi applie to your ytem, you can alter an internal link pair a hown below. Remove the board from it cae and find S101 a hown below... S101 Normal (Default) Invert Refit the board into the cae, replace the mall retaining crew and re-intall. 22

26 Troublehooting Problem Diplay update with new data, but the value eem wrong. For example, you know you are ending 100 but the diplay only read 83. Poible caue and cure 1. The meter may have been TARED at ome time and the tare offet value ha been tored in memory and i being ubtracted from new data. Cure: Switch the meter off. Connect terminal 7 to10 on the rear of the diplay. Switch meter on. Pre the RESET button on the front of the meter. Switch off and remove the link between terminal 7 and Check that the Data Edit DISPLAY and Data Edit LOSE etting uit your data tring. Diplay how trange illegible character 1. Baud rate may be incorrect. Check that the meter ha been et to the ame baud rate a the tranmitting device. 2. Connection tranpoed. If uing RS422/485, try tranpoing the cable to terminal 2 and 3 If uing 20mA TTY, ee page 21 23
