Obvious damage must be reported immediately. 5.
6 Commissoning, operation Store the instrument in its original packaging in a location that fulfils the conditions listed above. If the original packaging is not available, pack and store the instrument as described below: 1. Wrap the instrument in an antistatic plastic film. 2. Place the instrument, along with shock-absorbent material, in the packaging. 3. If stored for a prolonged period of time (more than 30 days), place a bag, containing a desiccant, inside the packaging.
6 Commissoning, operation 1. After removing the fixing elements, insert the device. 2. Check the seal to make sure it fits securely. 3. Click the fixing elements back into place and tighten the clamping screws by hand. Then use a screwdriver to tighten them another half a turn. CAUTION! The torque should not exceed 0.1 Nm! Indicator for wall mounting: The wall-type housing consists of an upper part and a lower part. A suitable seal has been inserted in the lower part to achieve protection IP 66.
6 Commissoning, operation 1. The cover flaps have to be opened on the right and left side. Loose the four fixing screws, which connect the upper and lower part of the enclosure, with a screw driver. Remove the upper part. 2. Fasten the enclosure to the wall. 3. Connecting cables have to be fed into the enclosure via the PG screws. 4. After connection the upper part of DI30 will be placed on the lower part. Using the four fixing screws, screw the upper part to the lower part.
6 Commissoning, operation 6.2 Electrical connection All the necessary signals for operation are connected to the rear terminals. The connecting terminals are designed as removable screw-type terminals with a grid pitch of 5.08 mm. This makes it possible to connect wires of up to 2.5 mm². 6.2.
6 Commissoning, operation Transmitter supply The DC 24 V transmitter supply is available at terminals 13 and 14. The transmitter supply is galvanic insulated from the measuring input. Current loop sensors (2-wire) and 3-wire and 4-wire sensors can be operated via the transmitter supply as long as their current consumption is not higher than 50 mA (Power consumption < 1.2 VA). Transmitter supply 13 Transmitter supply (-) 14 Transmitter supply (+) 6.2.
6 Commissoning, operation c) 0…5 V/0…10 V signal, 3-wire-transmitter The ground is bridged via the sensor, which eliminates the measuring error through the drop in voltage on the transmitter supply wires.
6 Commissoning, operation 6.3 Function and operation description 6.3.1 Operation The DI30 has 4 keys ([P], [], [], [O]), with which you can parameterise and call up various functions during operation. Additionally it has a 4-digit 7-segment display and two LEDs for displaying the alarm contacts.
6 Commissoning, operation 6.3.2 Switching on Before switching on you have to check all the electrical connections to make sure they are correct. On completion of the installation, the device can be switched on by applying the power supply. During the switching-on process a segment test is performed for approx. 1 second, whereby all LEDs on the front (including alarm LEDs) are triggered. After this, the type of software is indicated for approx. 1 second and then, also for 1 second, the software version.
6 Commissoning, operation 6.3.4 Description of the alarm outputs With the aid of the LEDs below the 7-segment display, you can view the switching state of the alarm outputs. An active relay is indicated by the relevant LED lighting up.
6 Commissoning, operation Switch-on delay The relay is on e.g. 10 seconds after reaching the threshold. Briefly exceeding the threshold does not lead to the relay being switched on. The switch-off delay functions in a similar manner, in other words it keeps the alarm output switched on until the parameterised time has elapsed. Optical response: display flashing The switching on of one or more alarm outputs can also be set to trigger a flashing of the display, to enhance the optical response. 6.
6 Commissoning, operation Changing to other program numbers To change between individual program numbers, hold the [P] key down and press the [] key for changing to a higher program number or the [] key for changing to a lower number. By keeping the keys pushed, e.g. [P] & [], the display will begin, after approx. 1 second, to automatically run through the program numbers. Example: Under PN0 a 1 is parameterized. Hold the [P] key down and press the [] key once. PN1 appears in the display.
6 Commissoning, operation Saving parameters All parameters must be acknowledged by the user by pressing the [P] key for one second. The changed parameters are then taken over as the current operating parameters and saved in the EEPROM. This is confirmed by horizontal bars lighting up in the display. Example: Save the parameters by pressing [P] for one second. All the newly entered data are confirmed by the unit. If no confirmation is received, the relevant parameters have not been saved.
6 Commissoning, operation Sensor linearisation In addition, non-linear sensors can be linearised with the aid of a characteristic line that can be saved in the indicator. This is described with the following example: The sensor signal must be parameterised in a strictly monotonously manner, i.e. every new calibration point (e.g. PN104) must have a higher input signal than the previous one (e.g. PN103) so that it is taken over by the indicator. Otherwise, no confirmation will be shown.
6 Commissoning, operation 6.6 Description of device parameters 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.
6 Commissoning, operation PN13: Indication time The indication time is the interval at which the display is updated. The longer the time between two indication cycles, the more calm the display. As a rule, the eye perceives the indication time of 1 sec. as very pleasant. If the adjusted indication time is longer than the adjusted measuring time (PN14), no averaging of the detected measuring values during the display time takes place.
6 Commissoning, operation To activate the set user level, you must enter a 4-digit number under PN51 as a “locking code” and confirm it by pressing the [P] key for approx. 1 second. On changing to programming mode, the unit jumps to the first authorised program number. If user level PN52 = 3, then, for example, the parameters of the alarm outputs can be changed, but changing the parameter of the measuring input (PN0) is not possible at this user level.
6 Commissoning, operation PN100 to PN110: Linearisation Through linearisation, the user has the possibility to linearise a non-linear sensor signal. A detailed description can be found in the chapter on Sensor linearisation. Under PN100, the desired number of additional set points can be released. Only after changing the number are they accessible via the configuration PN101 to max. PN110. If PN100 = 0, then no PN101 will be displayed.
6 Commissoning, operation 6.7 Program number table The program table lists all the program numbers (PN) with their function, range of values, default values and user level. PN Function Range of value 0 Measuring input Current, Voltage: 0 = Sensor calibration 1 = 0 ... 20 mA 2 = 4 ... 20 mA 3 = 0 ... 10 V 4 = 0 ... 5 V -999 ... 9999 -999 ... 9999 0=0 1 = 0.0 2 = 0.00 3 = 0.000 -999 … 9999 Parameters 1 to 4 make use of the factory calibration.

7 Maintenance and cleaning 6.8 Default values Reset to default values To return the unit to a defined basic state, a reset can be carried out to the default values. The following procedure should be used: Switch off the power supply Press button [P] Switch on the power supply and press [P] for further approx. 2 seconds until „- - - -“ is shown in the display. With reset, the default values of the program table are loaded and used for subsequent operation.
8 Faults 8 Faults Fault The unit permanently indicates overflow „ ¯ ¯ ¯ ¯ “ (4 bars in the upper part of the display) The unit permanently indicates underflow „ _ _ _ _ “. (4 bars in the lower part of the display) The device shows “HELP” in the 7segment display. Program numbers for parameterising the input are not available. „Err1“ lights up in the 7-segment display Solution The input has a very high measurement, check the measuring circuit.
