3.3.6. Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s configuration.
There is the possibility of connecting an active signal (= TTL, ...), a passive sensor-signal with NPN
(= NPN-output, push-button, relay, ...) or PNP (= a PNP output switching to +Ub, high-side push-button, ...).
When configuring the device with a NPN switching output, a pull-up-resistor (~11k referring to +3.3V) is
connected internally. So when you use a device with NPN output you don‘t need to connect a resistor
externally.
When configuring the device with a PNP switching output, a pull-down resistor (~11k referring to GND)
is connected internally. So when you use a device with PNP output you don‘t need a resistor externally.
It may be that your measuring-signal source needs the connection of an external resistor e.g. the pull-upvoltage of 3.3V is not enough for the signal source, or you want to measure in the top level frequency
range. In this case the input signal has to be treated like an active signal and you have to configure the device as „TTL“.
Hint:
when connecting the device you have to take care not to exceed the limits of the input
voltage respective the input current of the frequency-input.

(Rv1 is a current limiting resistor and may be shorted if necessary. It should never exceed the mentioned value.)
3.3.7. Connecting a counter signal
When configuring the device you can select 3 different input signal modes similar to the connection of
frequency- and rotation-signals. The connection of a sensor-signal for a counter-signal is the same used
for the frequency- and rotation-signal.
Please use the wiring diagram given below.
There is the possibility to reset the counter. When connecting contact 8 with GND (e.g. contact 7) the
counter will be reset. You can do this manually (e.g. with the help of a push-button) or automatically
(with one switching output of the device).
Hint:
When connecting the device, take care not to exceed the limits of the input-voltage or the inputcurrent of the frequency input.

Operating Instructions Digital Indicator DI15
3.4. Connecting switching outputs
The device features two switching outputs, with three different operating modes for each switching output, which are:
Low-Side:
“GND-switching“ NPN output (open-collector)
The switching output is connected to the negative rail of the supply voltage (connection 3
or 5) when active (switching output on).
High-Side:
“+Ub-switching“ PNP output (open-collector)
The switching output is connected to the positive rail of the supply voltage (connection 4)
when active (switching output on).
Push-Pull:
The switching output is connected to the negative rail of the supply voltage (connection 3
or 5) when inactive. When the switching output is active, it’s connected to the positive rail
of the supply voltage (connection 4).
In case of configuring one output as an alarm output, the output will be active in idle state (no alarm present). The output transistor switches or the push-pull output changes from +Uv to –Uv when an alarm
condition occurred.
Hint:
In order to avoid unwanted or wrong switching processes, we suggest to connect the
device’s switching outputs after you have configured the device’s switching outputs
properly.
Please take care that you must not exceed the limits of the voltage and of the maximum current
of the switching outputs (not even for a short period of time). Please take extreme care when
switching inductive loads (like coils or relays, etc.) because of their high voltage peaks, protective measures to limit these peaks have to be taken.
When switching large capacitive loads a series resistor for current limitation needed, because of
the high turn-on-current of high capacitive loads. The same applies to incandescent lamps,
whose turn-on-current is also quite high due to their low cold resistance.

3.5. Common wiring of several DI15
Inputs and outputs are not electrically isolated. When interconnecting several DI15`s you have to make sure
that there is no potential displacement.
Make sure to observe the following points:
- When several DI15`s are connected to the same power supply unit it is highly recommended to isolate the
sensors, measuring transducers etc.
- When the sensors, measuring transducers etc. are electrically connected, and you can’t manage to isolate
them, you should use separate electrically isolated power supply units for each device. Please note, that an
electric connection may also be created via the medium to be measured (e.g. pH-electrodes and conductivity-electrodes in fluids).

By this factor you can adapt the device to your transmitter or select a pre-scaling factor for large values
Example 1: Your flow rate transmitter supplies 165 pulses per litre. When setting a pre-scaling factor of 165, every
165th pulse (so 1 pulse per litre) will be used for further processing.
Example 2: Your transmitter is supplying about 5 000 000 pulses during the measurement, which exceeds the limit
of the DI15. But when setting a pre-scaling factor of 1000 only every 1000th pulse is used for further processing. So
you only got a value 5000 which won’t exceed the limit of the DI15.

-
Press button 1 to validate your selection. The display shows “AL.Lo“ again.
-
When pressing button 1 again, the device will be displaying “A.dEL“. (delay of the alarm-function)
-
Use button 2 and button 3 to set the desired delay of the alarm-function.
Note:
-
The unit of the value to be set is in [sec.]. The device will turn on the alarm after minimum
resp. maximum alarm value was active for the delay-time you have set.
Press button 1 to validate the delay time. The display shows “A.dEL“ again.
Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should start when
the temperature rises above 50°C resp. falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-value “AL.HI“ and 15°C for the minimum alarm-value “AL.Lo“.
The alarm will start after the temperature rises above 50°C and stays above 50°C for the entered
delay time resp. after it had been falling below 15°C and stays below 15°C for the entered delay
time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when there is no
alarm!
Now you finished configuring your device. Press button 3 to switch over to display the measuring value.

6. Offset- and slope-adjustment
The offset and slope-adjustment function can be used for compensating the tolerance of the used sensor,
resp. for fine adjustment of the used transducer resp. transmitter.
Please note:
The settings of the offset- / slope-adjustment will be cancelled, if no button was pressed for
more than 60 sec. Changes you may have made already won‘t be saved and will be lost!
Please note:
The settings of the offset- / slope-adjustment and alarm-boundaries will automatically be reset to
factory default when any changes for the settings “InP”, “SEnS“ resp. “Unit“ had been made!
Hint:
The buttons 2 and 3 are featured with a ‘roll-function‘. When pressing the button once the value will be raised
(button 2) by one or lowered (button 3) by one. When holding the button pressed for longer than 1 sec. the
value starts counting up or down, the counting speed will be raised after a short period of time.
The device also features a ‘overflow-function‘, when reaching the upper limit the device switches to the lower
limit, vice versa.
-
Turn on the device and wait after it finished its built-in segment test.
-
Press button 3 > 2 sec. (e.g. with a small screwdriver).
The device will be displaying „OFFS“ (offset).
-
Use button 2 and button 3 for setting the desired zero point offset-value.
Button 1 Button 2 Button 3
The input of the offset will be in digit resp. °C/°F.
The value that had been set will be subtracted from the measured value. (see below for further information)
-
Press button 1 to validate your selection. The display shows “OFFS“ again.
-
When pressing button 1 again, the device will be displaying “SCAL“. (scale = slope)
-
Use button 2 and button 3 to select the desired slope-adjustment.
The slope adjustment will be entered in %. The value displayed can be calculated like this:
Displayed value = (measured value – zero point offset) * (1 + slope adjustment [% / 100]).
Example: The setting is 2.00 => the slope has risen 2.00% => slope = 102%.
When measuring a value of 1000 (without slope-adjustment) the device would display 1020 (with slope adjustment of 102%)
-
Press button 1 to validate the selection of the slope-adjustment. The display shows “SCAL“ again.
Examples for offset- and slope-adjustment:
Example 1: Connecting a Pt1000-sensor (with an offset error depending on the cable-length of the sensor)
The device displays the following values (without offset- or slope-adjustment): 2°C at 0°C and 102°C at 100°C
Therefore you calculated: zero point: 2
slope:
102 – 2 = 100 (deviation = 0)
You have to set:
offset =
2
(= zero point-deviation)
scale =
0.00
Example 2: Connecting of a 4 ... 20mA-pressure-transmitter
The device displays the following values (without offset- or slope-adjustment): 0.08 at 0.00 bar and 20.02 at 20.00 bar
Therefore you calculated: zero point: 0.08
slope:
20.02 – 0.08 = 19.94
(= target-slope – actual-slope = 20.00 - 19.94)
deviation: 0.06
You have to set:
offset =
0.08
(= zero point-deviation)
(= deviation / actual-slope = 0.06 / 19.94 = 0.0030 = 0.30% )
scale =
0.30
Example 3: Connecting of a flow-rate-transducer
The device displays the following values (without offset- or slope-adjustment): 0.00 at 0.00 l/min and 16.17 at 16.00 l/min
Therefore you calculated: zero point: 0.00
slope:
16.17 – 0.00 = 16.17
(= target-slope – actual slope = 16.00 - 16.17)
deviation: - 0.17
You have to set:
offset =
0.00
(= deviation / actual-slope = - 0.17 / 16.17 = - 0.0105 = - 1.05% )
scale =
- 1.05
