1 Safety
1.1 General note
Read this document carefully and get used to the operation of the device before you use it.
Keep this document within easy reach near the device for consulting in case of doubt.
Mounting, start-up, operating, maintenance and removing from operation must be done by qualified, spe-
cially trained staff that have carefully read and understood this manual before starting any work.
The manufacturer will assume no liability or warranty in case of usage for other purpose than the intended
one, ignoring advices of this manual, operating by unqualified staff as well as unauthorized modifications
to the device.
1.2 Intended use
The device is a universal microcontroller based display -, monitoring - and controlling device.
The device has 1 universal-input, 2 relay outputs and an EASY Bus-interface. It can be used by measure-
ment and –regulation, limit monitoring, etc.
Prior to fulfil the referring requirements, the device has to be configured on the base of this manual. Wrong
configuration may lead to malfunction in the application. The commissioning expert / the operator is liable
for a suitable configuration.
The device is only to be operated in control panels ore suitable electric housings, where the connection
terminal area is sufficiently protected against touch.
The device is designed for industrial or commercial use.
Outdoor installation without suitable means of protection is not allowed.
The counting function is not to be used for e.g. consumption metering in the sense of the measuring in-
struments directive 2014/32/EU.
The safety guidelines of the manual are followed!
The unit does not contain any components that you can service or repair yourself.
All the described operations are only to be performed of skilled personnel that are authorized by the opera-
tor.
Any other use or use exceeding this is considered as non-conforming and leads to the expiration of any
liability or guarantee claims from the manufacturer.
Note: Combination / connection to other electrical equipment with CE marking does not automatically de-
liver a conform system. A new evaluation of the system’s conformity to the low voltage directive
(2014/35/EU) and EMC directive (2014/30/EU) by the manufacturer may be necessary, eventually others
have to be considered (e.g. machinery directive).
1.3 Skilled personnel
The mounting, electrical installation, start of operation, maintenance and decommissioning must only per-
formed by a skilled electrician.
Users of the readily installed device have to be sufficiently skilled in the operation of the device and able to
avoid risks. The operator of the arrangement is responsible for sufficient qualification the operators.

1.6 Reasonably foreseeable misusee
1.
This device must not be used at potentially explosive areas!
Do not use these products as safety or emergency stop devices or in any other
application where failure of the product could result in personal injury or material
damage.
Failure to comply with these instructions could result in death or serious injury
and material damage.
2.
This device must not be used at a patient for diagnostic or other medical
purpose.
1.7 Safety guidelines
1.
Faultless operation and reliability in operation of the measuring device can only be assured if
the device is used within the climatic conditions specified in the chapter 0
2.
Always disconnect the device from its supply before opening it. Take care that nobody can
touch any of the unit‘s contacts after installing the device.
3.
Standard regulations for operation and safety for electrical, light and heavy current equipment
have to be observed, with particular attention paid to the national safety regulations
(e.g. VDE 0100).
4.
When connecting the device to other devices (e.g. the PC) the interconnection has to be de-
signed most thoroughly, as internal connections in third-party devices (e.g. connection of
ground with protective earth) may lead to undesired voltage potentials.
5.
The device must be switched off and must be marked against using again, in
case of obvious malfunctions of the device which are e.g.:
- Visible damage.
- Device does not work like prescribed.
- Storing the device under inappropriate conditions for longer time.
When not sure, the device should be sent to the manufacturer for repairing or
servicing.
6.
Modifications or repairs of the device may not be performed by the customer. For maintenance
or repair the device must be sent to the manufacturer.

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.

Menu: press short = increase value
press long = roll-function with overflow-function *)
Button 3:
display min. value
button 3 + 5, >2s: activates menu „Offset- and slope adjustment“
button 3 + 2, >2s: reset min-/max. value

*) The input is made with the buttons 2 and 3. When pressing the button once the value will be raised (but-
ton 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 count-
ing 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.

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.
