WARNING!
... indicates a potentially dangerous situation that can result
in serious injury or death, if not avoided.
Information
... points out useful tips, recommendations and information
for efficient and trouble-free operation.
DANGER!
...identifies hazards caused by electric power. Should the
safety instructions not be observed, there is a risk of serious
or fatal injury.
2 Safety
Before installation, commissioning and operation, ensure that
the appropriate instrument has been selected in terms of
measuring range, design and specific measuring conditions.
Non-observance can result in serious injury and/or damage
to equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The DI30 is designed for the evaluation and display measuring transmitter
signals. With the alarm outputs, it is possible to perform simple control tasks.
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
WIKA operating instructions digital indicator model DI30 5
2 Safety
Please read the following safety advice and the assembly before installation
and keep it for future reference.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in the instrument malfunctioning. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
Notes on installation
There must be no magnetic or electric fields in the vicinity of the device,
e.g. due to transformers, mobile phones or electrostatic discharge.
Do not install inductive consumers (relays, solenoid valves etc.) near
the device and suppress any interference with the aid of RC spark
extinguishing combinations or free-wheeling diodes.
Keep input, output and supply lines separate from one another and do
not lay them parallel with each other. Position “go” and “return lines”
next to one another. Where possible use twisted pair. So, you receive
best measuring results.
Screen off and twist sensor lines. Do not lay current-carrying lines in the
vicinity. Connect the screening on one side on a suitable potential
equaliser (normally signal ground).
The device is not suitable for installation in areas where there is a risk
of explosion.
Any electrical connection deviating from the connection diagram can
endanger human life and/or can destroy the equipment.
The terminal area of the devices is part of the service. Here electrostatic
discharge needs to be avoided. Attention! High voltages can cause
dangerous body currents.
Galvanic insulated potentials within one complex need to be placed on
a appropriate point (normally earth or machines ground). So, a lower
disturbance sensibility against impacted energy can be reached and
dangerous potentials, that can occur on long lines or due to faulty
wiring, can be avoided.
The fuse rating of the supply voltage should not exceed a value of 1A
N.B. fuse.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

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. After the starting procedure, the unit
changes to operation/display mode.
6.3.3 General functi ons MIN/MAX Memory
The measured minimum and maximum values are saved in a volatile memory
in the unit and get lost when the unit is switched off.
You can call up the contents of the memory by pushing (less than 1 second)
the [▲] or [▼] key. The relevant value is indicated for approx. 7 seconds. By
briefly pressing the same key again, you will return immediately to the display
mode.

The alarm outputs have the following properties with regard to their switching
properties:
Active above threshold
The alarm output is off
below the threshold and
switched on when reaching
the threshold.
Active below threshold
The alarm output is on
below the threshold and
switched off on reaching the
threshold.

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: di splay 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.
6.4 Programming
The display shows the program numbers (PN) right-aligned, as a 3-digit
number with a P at the front.
Programming Procedure
The entire programming of the DI30 is done by the steps described below.

Change to the operating mode
If no key is pressed in programming mode for approx. 7 seconds, the unit
automatically returns to operating mode.
6.5 Description of the measuring input
The DI30 is equipped with a measuring input for standard signals that
enables standardised signals (e.g. 4 … 20 mA) from all kinds of different
measuring transmitters on the market to be measured directly.
Factory calibration
For this, various sensor values for 0 … 10 V, 0 … 5 V, 0 … 20 mA and 4 …
20 mA are stored in the unit and can be called up via the parameter PN0.
They are called factory calibrations, because the data were established
during production and are saved permanently in the unit. It means that a preadjusted transmitter can be operated directly with the indicator, without any
need to previously connect the signal to be measured to the indicator.
The indicator can be scaled freely according to the physical dimension to be
measured.
Sensor calibration
If, on the other hand, the sensor has not been pre-calibrated, the indicator
can be adjusted and calibrated direct via the measurement together with the
sensor path. This can be selected via the parameter PN0 = 0 and is
consequently called sensor calibration.

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. On the
other hand, the relevant indication values do not need to increase constantly.
They can also fall or alternate between rising and falling.
Example: Linearisation of a pressure transmitter (0...100 mbar) with output
0…20 mA.
To program e.g. 5 additional calibration points, “5” must be entered under
PN100.
Subsequently, for each of the calibration points, the voltage/current must be
applied to the unit and the respective indication value programmed under the
following program numbers PN101 - PN105.
The indicated value before correction can be either calculated from the known
characteristic line of the transmitter or determined empirically.
The non-linear range is between 0 ... 75 mbar. For calibration point 101, this
means:
A pressure of 15 mbar, the transmitter delivers 3.3 mbar instead of the ideal
value of 3.0 mbar. Since 20 mA in the display corresponds to 100.0 mbar, 3.3
mA in the display corresponds to 16.5 mA before the correction.

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 “6.7 Program Number Table”)
PN0: Measuri ng 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 PN0 = 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 PN0 = 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
parameterised characteristic line. This may be necessary, if for example a
pressure transmitter ages over the course of time, giving rise to a shift in the
zero point. With the parallel shift the transmitter can be adjusted back to the
zero point. Another application is to parameterise a certain tank level to zero
and have any deviation from this level displayed.
PN10: Zero point suppression
Via the zero point suppression, an indication value window can be defined as
zero. This means, for example, that at PN10 = 10, all indication values
between –10 … +10 are shown in the display as zero. This function is
intended to produce a reliable zero indication at high display resolution and
low sensor accuracy around zero. This could be, for example, the rpm of an
engine for which a zero would be expected in the display when standing still.

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. The display will be always refreshed with the newest detected
measuring value.
PN14: Measuring time
The measuring time corresponds to the conversion time of the A/D
conversion, which determines the response time of the alarm outputs. The
longer the conversion time the smaller the influence of disturbances and the
higher the resolution of the measured signal.
PN50 to PN52: Security setting, user level
With the parameters in the security settings, access to the program numbers
is regulated through the setting of various user levels. The user levels divide
the access into various levels. The user is only given access to the settings
authorised by the system operator, such as the setting of thresholds. The
lower the figure for the user level given in PN52, the lower is the security level
of the unit parameters against user intervention. (●: available function at the
selected userlevel)
The user levels 1, 3 and 7 are reserved user levels at which access to the
higher numbered user level is active.
The parameterised user level PN52 is active as long as the locking code
PN51 and the access code PN50 are different. On delivery of the DI30 both
parameters are set to 0000, so that the programming lock is deactivated.
WIKA operating instructions digital indicator model DI30 27
6 Commissoning, ope ration
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.
In order to obtain access to all program numbers later (equivalent to user
level 0), you have to enter under PN50 the same code you entered before
under PN51. You must then acknowledge this by pressing the [P] key for
approx. 1 s. After this you have access to all program numbers.
Information
If the locking code becomes lost, the unit can be set to the
default value 0000 at the manufacturer's without any data
loss.
PN54: Allocation of functions of the zero k ey
By pushing of the zero key [O] functions like e.g. TARA and HOLD can be
actuated or an offset shift can be preset. By allocation of TARA the key needs
to be pushed for at least 1 second. The device confirms the function by
showing „0000“ in the display. With activated offset shift, the value in PN5 will
be added to the initial value directly by pushing the key. A display hold can
only be actuated for approx. 20 seconds. By pushing the zero key again one
turns back into the current measurement directly.
During HOLD phase the display flashes.
PN59: Display flashing
By activating the display flashing, various alarm states can be optically
reinforced. The trigger for the display flashing can be freely assigned to the
setpoint outputs.
PN60 to PN75: Alarm out put s
The behaviour of the alarm outputs can be influenced via various program
numbers. The data refer to the scaled measurement and are updated with the
set measuring time. A description of the various parameters is given in
chapter “6.3.4 Description of alarm outputs”.

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. To
monitor the desired linearisation, all the set points should first be
parameterised, otherwise there may be deviations from the desired value in
the display!
PN200: Serial number
Under PN200 the 4-digit serial number can be called up, that allows allocation
to the production process and the manufacturing procedure. This parameter
can only be viewed.
