Before Startup
When operating the signal converter, certain parts
of the module can carry dangerous voltage!
Ignoring the warnings can lead to serious injury
and/or cause damage!
The signal converter should only be installed and
put into operation by qualified staff. The staff must
have studied the warnings in these operating
instructions thoroughly.
The signal converter may not be put into operation if
the housing is open.
In applications with high operating voltages
sufficient distance and isolation as well as shock
protection must be ensured.
Safe and trouble-free operation of this device can
only be guaranteed if transport, storage and
installation are carried out correctly and operation
an maintenance are carried out with care.
Appropriate safety measures against electrostatic
discharge (ESD) should be taken during range
selection and assembly on the transmitter.
►
Short description
The programmable transmitter is designed for operating various
industrial sensors. The measured values are converted into a
current or voltage signal. The configuration can be done either via
DIP switch for preference measuring ranges or extensive ranges via
an USB-interface with the PC configuration program DRAGOset.
The 3-way isolation guarantees reliable decoupling of the sensor
circuit from the processing circuit and prevents linked measurement
circuits from influencing each other. The auxiliary power can either
be supplied via the connection terminals or via the In-Rail-Bus
connector (see Accessories).
►
Configuration and startup
Configuring with DIP switch
Use the DIP switches to configure the device, according to table.
Via the DIP switches you can select only a limited number of
sensors. A wider range of sensors you can select via software
configuration.
Configuring with software DRAGOset
Use the software DRAGOset to configure the device. Changes to
the configuration and parameterization data can be performed both
during operation with a connected measuring circuit and in a
disconnected state.
The DRAGOset software is available for download free of charge at:
www.drago-automation.de
The device is equipped with a programming socket on the front. Use
the DRAGOset USB Converter (Order no.: DZU1201) for connecting
the device to the PC. To change the configuration and
parameterization DIP switch S1- 1, 2, 3 have to be set ON!
Commissioning Function
The Commissioning Function with a stepped keystone signal on
output supports a fast and simple testing of cabling and connection
of downstream devices or measuring adjustment. Press the function
button located behind the front cover for longer than 3 seconds. The
Commissioning Function will be indicated with a yellow LED
(quick double off).

The stepped keystone signal is output continuously. Exit the
Commissioning Function by pressing the button again for 3 seconds
or power off.
Teach-In Function
for Potentiometer, Resistor and mV- Input
The Teach-In function can be used to teach in the start value and
end value. There are two ways of the Teach-In function:
●
Automatic set up mode (Auto Teach-In)
●
Manual Teach-In of the start and end value (Manual-Teach-In)
The taught-in values remain stored under the Teach-In setting. The
start value is 0 % and the end value is 100 % by default.
Starting the Teach-In Function
Use the function button located behind the front cover of the device
to teach in the device (use screw driver to push).
1. Configure the device using the DIP switches on the side of the device.
2. Press the function button for longer than 3 seconds.
The yellow LED will flash quickly
3.
Auto Teach-In
: Set input signal to both min and max range limits
as often as desired. Start value and end value will be
automatically
determined and recorded.
or
Manual Teach-In
: Set input signal to first range limit and press
the function button for around 0.5 seconds. Set second limit and
press the function button for around 0.5 seconds.
This can be
repeated as often as required. The value of the last two
keystrokes will be stored for start value and end value.
Ending the Teach-In, Saving the Start Value and End Value
Press the function button for longer than 3 seconds. Release the
button when the yellow LED lights up constant. The values are
stored. The green LED indicates the successfully storage.
Ending the Teach-In without Saving the Start Value and End Value
Press the function button for longer than 6 seconds. Release the
button when the yellow LED starts to flash again after lit up
constant. The values are ignored and not stored.
or
Switch off the device. The values are not stored.
Teach-In Fault
If the span between the start value and the end value is too small,
the red LED will flash slowly after saving the values (configuration
error). In case of a fault, the Teach-In function must be performed
again in its entirety.
