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
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.

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
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 10. 2. 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
