1. The DI30 has a number of unit parameters with which the function of the indicator can be adjusted to the relevant measuring tasks Because of the large number of these settings and the limited possibility of displaying them on the 7 segment display the parameters have been given consecutive numbers see chapter 6 7 Program Number Table PNO Measuring input One of the aspects in the basic configuration is the desired measuring input which consists of the terminal selection and the relevant factory or sensor calibration PN1 and PN2 Scaling The two program numbers 1 and 2 are used to scale the indication With these two parameters the end value and start value are parameterised If sensor calibration has been selected via PNO 0 then the current for the relevant sensor signal must be applied during programming Otherwise a simple allocation of the selected input configuration will be made For example at PNO 3 which corresponds to a standard signal input 0 10 V the value saved under PN1 will be indicated at 10 V and the value saved under PN2 will be indicated at 0 V PN3 Decimal point By changing this parameter the number of places shown after the decimal point in the display is changed This parameter has no influence on the scaling of the indication value only on the position of the decimal point in the display PN5 Offset shift With this parameter it is possible to carry out a parallel shift of the parameteris2. fixed via screws for panel thicknesses from 1 mm to 10 mm Wall mounting enclosure Material ABS black cable gland Ingress protection IP 65 Dimensions 160 x 130 x 60 mm w x h x d Cable gland Cable thickness 4 0 8 0 mm Mounting Fixing holes for screws Permissible ambient conditions Operating temperature 0 60 C Storage temperature 20 80 C Humidity 0 75 relative humidity non condensing CE conformity EMC directive 2004 108 EC EN 61326 1 Emission Group 1 Class B and Immunity industrial locations Low voltage directive 2006 95 EC EN 61010 1 Items in curved brackets are optional extras for additional price For further specifications see WIKA data sheet AC 80 05 and the order documentation 10 WIKA operating instructions digital indicator DI30 4 Design and function Operating elements 1 2 3 4 1 Program key 4 Zero key 2 DOWN key 5 7 segment display 3 UP key 6 7 LEDs for displaying the alarm contacts 4 Design and function 4 1 Short description With the digital indicator DI30 standard signals DC 0 4 20 mA or DC 0 5 10 V can be measured The 4 digit display shows the measurements or the scaled value of the measurement During programming the display is used to indicate the set values and the user prompts Two relays alarm outputs 1 and 2 are available to monitor threshold values the status of which is displayed via two separate LED on the front The integrated DC 2
