Safety Instructions
Safety instructions for DEWETRON amplifiers
The DEWETRON data acquisition systems and ampliers may only be installed by experts.
Read your manual carefully before operating.
Observe local laws when using the ampliers.
Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal), a
non interruptible safety earth ground must be provided from the mains power source to the product input
wiring terminals or supplied power cable.
DO NOT operate the product in an explosive atmosphere or in the presence of ammable gases
or fumes.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built
into this product have been impaired, either through physical damage, excessive moisture, or any other
reason, REMOVE POWER and do not use the product until safe operation can be veried by service-
trained personnel. If necessary, return the product to a DEWETRON sales and service o󰀩ce for service
and repair to ensure that safety features are maintained.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields.
Procedures involving the removal of covers or shields are for use by service-trained personnel only.
Under certain conditions, dangerous voltages may exist even with the equipment switched o󰀨. To avoid
dangerous electrical shock, DO NOT perform procedures involving cover or shield removal unless you
are qualied to do so.
No modications are allowed at the ampliers.
DO NOT service or adjust alone. Do not attempt internal service or adjustment unless another person,
capable of rendering rst aid and resuscitation, is present.
DO NOT substitute parts or modify equipment: Because of the danger of introducing additional hazards,
do not install substitute parts or perform any unauthorized modication to the product. Return the product
to a DEWETRON sales and service o󰀩ce for service and repair to ensure that safety features are
maintained.
DO NOT touch internal wiring!
DO NOT use higher supply voltage than specied!
Use only original plugs and cables for harnessing.
Safety of the operator and the unit depend on following these rules.

Calibration information
All DEWETRON modules are calibrated at 25 °C after a warmup time of 30 minutes and meet their
specications when leaving the factory.
The time interval for recalibration depends on environmental conditions. Typically, the calibration should be
checked once a year.
Calibration certicates are available from DEWETRON as an option. DEWETRON o󰀨ers two types:
ISO traceable DEWETRON certicate
Calibration certicate according to ÖKD (equivalent to DKD)
This manual contains no calibration information. For self calibration, there is a separate calibration kit for the
DAQ series modules available. The CAL-KIT contains the required cables, software and instructions.

RS-232/485 interface
HSI/DAQP modules can be congured via
RS-485 interface, PAD modules require
this interface for all data transfers.
For all DEWETRON systems, an internal
RS-232/485 converter is available
(standard with DEWE-800, -2000, -2500, -3000, -4000, -5000 series systems). This converter allows
communication with HSI/DAQP and PAD modules.
To communicate with the modules, the RS-232 interface has to be set to the following parameters:
baud rate: 9600 bps
data bits: 8
parity: no parity
stop bits: 1
handshake: not required
HSI/DAQP module configuration
1. Push button selection
All ranges and lters can be selected directly by pressing the push buttons on the module. Approx. 15 sec.
after changing range and / or lter, the range and lter information is stored in an EEPROM. This procedure
increases the livetime of the EEPROM.
The current input range setting is shown all the time by LED. To change the range just press RANGE button
a few times until the required range is displayed.
To see the current lter setting just press the FILTER button once. The corresponding LED is ashing for
approx. 3 seconds. Within this time, the lter can be selected by pressing the FILTER button again. Approx.
3 seconds after the last key activity, the information will be stored, the LED stops ashing and shows the
input range again.
CAUTION: Power loss during this time leaves the module in the former settings.
2. RS-232/485 programming
All ranges and lters can also be selected via RS-232/485 interface. All new DEWE-800, -2000, -2500,
-3000, -4000, -5000 series systems are prepared as a standard to work with HSI/DAQP modules.
The easiest way to change the conguration is to use the DEWECong software, which comes as a standard
with the DEWETRON data acquisition system.
Detailed information about HSI/DAQP modules programming for customer applications is available in the
DEWE-Modules Programmers Reference Manual.
CAUTION: All range and lter changes which are done via RS-232/485 interface are not stored in the
EEPROM of the HSI/DAQP modules! You have to store this information in a separat initialisation le to
keep settings information for next system start!
PAD module communication
All PAD modules are only working through the RS-232/485 interface. All new DEWE-800, -2000, -2500,
-3000, -4000, -5000 series systems are prepared as a standard to work with PAD modules. The easiest
way to change the conguration is to use the DEWECong software, which comes as a standard with the
DEWETRON data acquisition system.
Detailed information about PAD modules programming for customer applications is available in the
DEWE-Modules Programmers Reference Manual.

Front panel control
LED indication:
The HSI-LV series module has a set of 8 LEDs showing the current input range (constant active)
and lter range (ashing) setting.
Filter Range Range Filter
20 Hz 50 V 200 mV 105
10 Hz 10 V 50 mV 104
3 Hz 5 V 10 mV 103
1 Hz 1 V U/B 102
The U/B LED shows the input mode: If this LED is o󰀨, the bipolar input range is selected, otherwise the
unipolar mode is selected.
Power On Default function
You can store the actual settings of the module in the internal EE-Prom memory. Once the module restarts,
it comes up automatically with these setting. This is important for stand alone applications and for fail save
reasons. If the function is deactivated the module automatically remembers the last pushbutton selected
range and lter.
Push button operation:
Select range: Push the RANGE button several times shortly until the LED displays the
desired input range.
Select lter: Push the FILTER button once - the LEDs will ash for approx. 3 seconds and
display the current lter setting. Push the FILTER button within the three seconds
several times until the ashing LED displays the desired lter range.
Change input mode: Keeping the RANGE button pressed for more than 3 seconds, the input mode
changes from unipolar to bipolar or vice versa.

The module has 9 selectable low pass lters from 100 Hz to 1 MHz. The lter characteristic could be chosen
between Butterworth 2nd order or Bessel 2nd order. The highest lter is a 3rd order lter with a guaranteed
-3 dB bandwidth of 2 MHz. This lter structure is the same for all HSI modules.
Typical lter transfer function:
AC accuracy with activated filter
With activated hardware lter an additional % of reading error has to be considered due to the damping of
the lter. This error depends on the signal frequency f and the selected ler frequency f0.
HSI Ready
Please ensure that also the Hardware that carries the HSI Module
is not limiting the 2 MHz bandwidth.
Older systems may have a x installed 350 kHz lter. The HSI series
modules will also work in these systems, but the bandwidth will be
limited to the system bandwidth.
