2. Declaration of Conformity
The device was tested according to the applicable standards.
Conformity was proofed. The declaration of conformity is
available at the manufacturer BTR NETCOM GmbH.
Notes Regarding Device Description
These instructions include indications for use and mounting of
the device. In case of questions that cannot be answered with
these instructions please consult supplier or manufacturer.
The indicated installation directions or rules are applicable to
the Federal Republic of Germany. If the device is used in other
countries it applies to the equipment installer or the user to
meet the national directions.
Safety Instructions
Keep the applicable directions for industrial safety and preventi-
on of accidents as well as the VDE rules.
Technicians and/or installers are informed that they have to
electrically discharge themselves as prescribed before installati-
on or maintenance of the devices.
Only qualified personnel shall do mounting and installation
work with the devices, see section “qualified personnel”.
The information of these instructions have to be read and un-
derstood by every person using this device.
Symbols
Warning of dangerous electrical voltage
Danger
means that non-observance may cause risk of life,
grievous bodily harm or heavy material damage.
Qualified Personnel
Qualified personnel in the sense of these instructions are persons
who are well versed in the use and installation of such devices
and whose professional qualification meets the requirements of
their work.
This includes for example:
• Qualification to connect the device according to the VDE
specifications and the local regulations and a qualification to
put this device into operation, to power it down or to activate
it by respecting the internal directions.
• Knowledge of safety rules.
• Knowledge about application and use of the device within the
equipment system etc.
1. Description
The Modbus module with 4 analog outputs is designed for local
switching operations. It is suitable as variable encoder, for ex-
ample ventilation or mixing valves, valve positions etc. The out-
puts can be adjusted via a Modbus-Master. Setting of the slave
address, bit rate and parity is done with the two address
switches (x1 / x10) on the front. Possible settings are addresses 00
to 99 and bit rates 1200, 2400, 4800, 9600, 19200, 38400, 57600
und 115200 Bd.
The device does not participate in bus communication if the
address is 00 (reserved for broadcast commands).
Communication with the master can be monitored with a
watchdog timer. If master or communication fail the outputs are
switched to their basic state (secure state) and the red LED is ligh-
ting. The timer restarts with each valid message addressed to the
device. When defining the time constant it is necessary to take
account of the baud rate, the number of slaves on the bus and the
length of the messages per slave.
