2.2 Function
It is a universally applicable microprocessor controlled displaying, monitoring and controlling device.
The device is supporting one universal interface for the connection of:
- Standard transmitter signals (0-20 mA, 4-20 mA, 0-50 mV, 0-1 V, 0-2 V
and 0-10 V),
- RTD (Pt 100 and Pt 1000),
- Thermocouple probes (type K, J, N, T and S)
- Frequency (TTL and switching contact)
As well as rotation measuring, counting, etc...
Additionally two switching outputs, which can be configured as 2-point-controller, 3-point-controller, 2-point-
controller with min./max. alarm common or individual min./max. alarm. The state of the switching outputs is
displayed with 2 LED, whereby the LED (label 1) is displayed the state of the contact from relay 1 and the
LED (label 2) the state of the contact from relay 2.
(LED on = contact connected).
Furthermore both devices support one EASY Bus-interface for communicating with a host computer that
makes the device to a EASY Bus-module.
The device is being examined and completely calibrated.
Before the device can be used, it has to be configured for the customer’s application.
In order to avoid undefined input states and unwanted or wrong switching
processes, we suggest to connect the device’s switching outputs after You
have configured the device properly.
By calling a configuration menu (configuration of the measuring input, con-
figuration of the analog output, configuration of the output function, offset-
and slope-adjustment) the measurement and regulation of the device will be
deactivated.
By leaving the menu the device will be reinitialised and the measur-
ing/regulation will be started again.
At the input function “counter” the counter state will be reset by leaving the
menu.

5.3.6 Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s con-
figuration. 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 +Us, high-side push-button,
...)
When configuring the device with a NPN switching output, a pull-up-resistor (~7 kΩreferring 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 (~7 kΩreferring 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-
up-voltage of 3.3V is not enough for the signal source, or you want to measure in the top level fre-
quency range. In this case the input signal has to be treated like an active signal and you have to con-
figure the device as „TTL“.
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.

5.3.7 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 in this chapter.
There is the possibility to reset the counter. When connecting contact 4 with GND (e.g. contact 6) 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).
When connecting the device, take care not to exceed the limits of the input-
voltage or the input-current of the frequency input.

E44.X.01.6C-04 Mounting- and Operating Manual GIR 300 page 13 of 34
5.4 Connecting switching outputs
In order to avoid unwanted or wrong switching processes, we suggest to connect the de-
vice’s switching outputs after you have configured the device’s switching outputs properly.
The device have 2 outputs:
•Output 1: Relay, make contact
• Output 2: Relay, break contact
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 relays, coils etc.).
Because of their high voltage peaks, protective measures (e.g. RC-element) to
limit these peaks have to be taken.
More information about switch states from the output functions, see chapter Feh-
ler! Verweisquelle konnte nicht gefunden werden.
In case of configuring one output as an alarm output, the output will be closed in
idle state (no alarm present). The output relay opens when an alarm condition oc-
curred. See chapter7.2 and 7.3
5.5 Common wiring of several devices
The inputs of the device are not electrically isolated to the power supply.
When interconnecting several of these devices you have to make sure that there is no potential displace-
ment.
Especially consider the following points:
- If several encoders are supplied with the same voltage (sensors, transducers), it is advisable to isolate
each other electrically.
- If encoders have an electrical connection, the supply voltage should be electrically isolated. Please note
that electrical connection of the encoders also can be arising with the measuring medium (e.g. liquid).
6 Configuration
6.1 General description and notes to the operating of the menu
Selection of parameters:
Switch to the next parameter with Button1 resp. save after the last pa-
rameter.
Parameter adjustment:
With button 2 or button 3you can adjust its value.
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 of the range, the device
switches to the lower limit, vice versa.
Button 1 Button 2 Button 3

E44.X.01.6C-04 Mounting- and Operating Manual GIR 300 page 14 of 34
If no key is pressed > 60 sec. the menu will be automatically closed.
When changing the measuring mode “FUNC“ the values for the offset and slope-
adjustment will be reset. Furthermore a change of the device scaling for standard sig-
nals (di.Lo, di.Hi, dP) or of the resolution can possibly influence the values of the offset
and slope-adjustment. Therefore you may check your offset and slope-adjustment after
changing the input configuration.
The change of the device scaling for standard signals (di.Lo, di.Hi, dP) can possibly
change the switching and alarm points. Therefore you may check your output settings
afterwards!
The alarm-output is inverted!
This means, that the output will be active when there is no alarm!
6.2 Selecting an input signal type
- Turn the device on and wait until it completed its built-in segment
test.
- Press button 2 for >2 sec. (e.g. with a small screw driver)
The device displays “InP“ ('INPUT').
- Use button 2 or button 3 (middle or right button) to select the in-
put
signal (see table below).
- Validate the selection with button 1 (the left button). The display
will show “InP“ again
Depending on the selected input signal, additional configurations will be needed.
