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.

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 input-

current of the frequency input.

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 vo ltage 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 larg e ca pacitive loads a se ries resist or for curren t limit atio n needed , bec ause 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.

Hints: Connections 3 and 5 are internally electrically connected. When switching higher currents (> 50 mA) , the –Uv connec-

When doing this, you get rid off ground displacement.

Inputs and outputs ar e not elec tricall y isolate d. W hen interconnec ting se veral DI 15`s you have to m ak e sure that there is no potential displacement.

Make sure to observe the following points:

- When several DI15`s are connected to the s ame power suppl y unit it is highl y recomm ended to isolate the

sensors, measuring transducers etc.

- When the sensors, m easuring transduc ers etc. are elec tricall y connected, and you ca n’t manage to is olate

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 m ediu m to be m eas ured ( e.g. pH-elec tr od es and cond uc ti vity-electrodes in fluids).

- Press button 1 to validate the delay time. The display shows “A.dEL“ again.

Example:

You want to have a temper ature alar m-monitor ing of a greenhous e. The alarm shoul d start whe n

the temperature rises above 50°C resp. falls below 15°C. Therefore your settings will be 50°C for t he maximum alar m-value “AL.H I“ and 15°C for th e minimum alarm-value “AL.Lo“. The alarm will start after the temp erature rises abov e 50°C and s tays above 50° C for the entered delay time resp. after it ha d 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!

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 ( You have to set: offset = 2

scale = 0.00 Example 2:

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 deviation: 0.06

You have to set: offset = 0.08 scale = 0.30

Example 3: 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 deviation: - 0.17

You have to set: offset = 0.00 scale = - 1.05

Connecting of a 4 ... 20mA-pressure-transmitter

Connecting of a flow-rate-transducer

deviation = 0

(= zero point-deviation)

(= target-slope – actual-slope = 20.00 - 19.94) (= zero point-deviation)

(= deviation / actual-slope = 0.06 / 19.94 = 0.0030 = 0.30% )

(= target-slope – actual slope = 16.00 - 16.17)

(= deviation / actual-slope = - 0.17 / 16.17 = - 0.0105 = - 1.05% )
