Chapter 1
Safety precautions
Important information
Read these operating instructions before starting the unit. They provide you with
important information on the use, safety and maintenance of the units. This helps
you to protect yourself and prevent damage to the unit.
Information intended to help you to avoid death, bodily harm or considerable
damage to property are highlighted by the warning triangle shown here; it is
imperative that this information be properly heeded.
The operating instructions are intended for trained professional electricians familiar
with the safety standards of electrical technology and industrial electronics.
Store these operating instructions in an appropriate place.
The manufacturer is not liable if the information in these operating instructions are
not complied with.
Safety
Components inside the units are energized with electricity during operation.
For this reason, mounting and maintenance work may only be performed by
professionally-trained personnel while observing the corresponding safety
regulations.
The repair and replacement of components and modules may only be carried out
by the manufacturer for safety reasons and due to the required compliance with
the documented unit properties.
The units do not have a power switch. They are operative as soon as the operating
voltage is applied.
Intended use
The units are intended for use in industrial environments. They may only be
operated within the limit values stipulated by the technical data.
When configuring, installing, maintaining and testing the units, the safety and
accident-prevention regulations relevant to use in each individual case must be
complied with.
Trouble-free, safe operation of the units requires proper transport, storage,
installation, mounting and careful operation and maintenance of the units.
Mounting and installation
The attachment options for the units were conceived in such a way as to ensure
safe, reliable mounting.
The user must ensure that the attachment hardware, the unit carrier and the
anchoring at the unit carrier are sufficient to securely support the unit under
the given surrounding conditions.
The units are to be mounted in such a way that they can be opened up while
mounted. Sufficient space for the cables must be available in the unit near the
cable infeed.
Sufficient space is to be kept clear around the units to ensure air circulation and to
prevent the build-up of heat resulting from use. The relevant information must be
heeded in the case of units ventilated by other means.
When the housing fasteners are opened, the front frame of the housing
hinges out upward or downward (depending on the unit version)
automatically.
BAL C9302 SER EN 1.21

Grounding
All devices are equipped with a metal housing. They comply with safety class I and
require a protective earth connection. The connecting cable for the operating
voltage must contain a protective earth wire of a sufficient cross section (DIN VDE
0106 part 1, DIN VDE 0411 part 1).
EMC measures
The devices comply with the EU Directive 89/336/EEC (EMC Directive) and
provide the required interference immunity. Observe the following when connecting
the operating voltage and data cables:
ƒ
Use shielded data cables.
ƒ
The data and operating voltage cables must be laid separately. They may not
be laid together with heavy-current cables or other interference-producing
cables.
ƒ
The cable thickness must be properly assessed (DIN VDE 0100 Part 540).
ƒ
The cable lengths inside the units are to be kept as short as possible to
prevent interference. This applies especially to unshielded operating voltage
cables. Shielded cables are also to be kept short due to any interference which
might be emitted by the shielding.
ƒ
Neither excessively long cables nor cable loops may be placed inside the
units.
ƒ
The connection of the cable shielding to the functional ground (PE) must be as
short and low-impedance as possible. It should be made directly to the
mounting plate over a large area with a conductive clip:
control
data line terminals
bare
metal surface
mouting plate
conductive clamp
ƒ
Disposal
6
The cable shielding is to be connected at both cable ends. If equipotential
bonding currents are expected due to the cable arrangement, electrical
isolation is to be performed on one side. In this case, capacitive connection
(approx. 0.1µF/600 V AC) of the shielding on the isolated side must occur.
Units or unit parts which are no longer needed are to be disposed of in accordance
with the regulations in effect in your country.

BAL C9302 SER EN 1.21
Parameterization
The parameterization of the unit is done by means of a menu in the menu display
(see chapter 3).
Serial Interface
The serial interface is located on the screw-type terminal strip of the control
computer. Depending on the device model, it has the following formats:
C9302-S0
C9302-T0
RS485 and RS232
TTY 20mA and RS232
The interface format is set in menu item 1 (see chapter 3).
The switches S1 (Tx) and S2 (Rx) serve for locking the data lines of the RS485
(see chapter 5).
Preferably, the interfaces RS485 or TTY 20 mA are to be used for activation. They
are galvanically isolated from all other electric circuits and provide the best
preconditions for a reliable and safe operation of the devices due to its physical
characteristics.
The interface RS232 is determined for testing purposes and is not recommended
for activation because of its physical properties.
Function inputs
The functional inputs allow, independently of commands, via Ethernet interface to
reduce the brightness and flashing of the display(see chapter 3). It is located on
the screw type terminal of the control computer.
The function inputs are PLC-compatible and are designed for the following signal
voltages:
Signal voltage: L = -3.5...+5 V (open input = L)
H = +18...30 V (active H), M = reference potential
Auxiliary voltage
The units supply terminal P with an auxiliary voltage galvanically isolated from the
operating voltage (24 V ± 25%, max. 50 mA, M = reference potential). It can be
used for supplying power to the current loop or as H signal.
Menu display
The menu display represents a menu for unit parameterization (see chapter 3).
In normal operation, On nE is shown in the menu display.
Menu buttons
The menu can be operated by means of the menu buttons (see chapter 3).
Switching output
The devices dispose of a switching output (relay) with potential-free change-over
contact (NC, NO, CO).
Status indicators
The status indicators (LEDs) of the central processing unit have the following
function:
DATA Data are received

Control
Serial Interface
Select in menu item 1 between the interface formats which are available in the
central processing unit.
C9302-S0
C9302-T0
RS485 or RS232
TTY 20mA or RS232
In the interface format RS485, you can select several settings in the menu item 1.
Which settings are to be selected is described in chapter 5.
Parity, baud rate and protocol reply are set in menu items 3, 4 and 6.
In the interface format RS485, the XON/XOFF handshake is active.
In the interface format RS232, the RTS/CTS handshake is active.
If ACK/NAK is selected in menu item 6, the control computer transmits the
character ACK (06h) after receipt of correctly addressed data. In case of an error, it
transmits the character NAK (15h).
Addressing
The address of the control computer (= basic address) is set in menu item 9. The
address precedes the data to be displayed in a 2-digit ASCII format.
Commands which apply to all display fields are transmitted to the basic address.
Commands for a single display field are transmitted to its field address.
The field address is composed of the basic address and an address offset. Display
field H1 has the offset 1, display field H2 the offset 2 etc.. The caption of the
display fields is documented in the included logic diagram of the XC-Boards®.
Example 1: The control computer has the basic address 40. The field address of
the display field H2 is 40 + 2 = 42.
Example 2: The control computer has the basic address 40 (protocol CR/LF). The
brightness of all display fields shall be reduced. The command is
40$L1<CR><LF>.
Example 3: The control computer has the basic address 40 (protocol CR/LF). The
display field H2 shall display the value 123. The command is 42123<CR><LF>.
Broadcast address
The control computer also reacts on the basic address 00, independently from the
basic address set in menu item 9. It allows the activation of all control computers
provided in an XC-Board®.
Example: The brightness of all display fields shall be reduced in an XC-Board® with
several control computers. The command is (protocol CR/LF): 00$L1<CR><LF>
In case of an interfacing with the basic address 00 the control computer does not
transmit any telegram answer, independently from the setting under menu item 6.
Protocol
The data to be displayed are transmitted to the control computer in ASCII format,
including the field address.
If the protocol CR/LF is selected under menu item 5, each telegram is to be
terminated with the character <CR> (0Dh), <LF> (0Ah) or the combination
<CR><LF>.
If the protocol STX/ETX is selected, the data including the address are embedded
between the characters <STX> (02h) and <ETX> (03h).
The representation in numeric display fields is right-aligned. The representation in
alphanumeric fields is left-aligned.

BAL C9302 SER EN 1.21
Flashing
The flashing of all display fields can be activated by means of the following
commands to the basic address of the control computer (protocol CR/LF):
$F1<CR><LF>
$F0<CR><LF>
Flashing on
Flashing off
If $F1 is sent in the data telegram to a field address, the succeeding digits will flash
until the end of the data telegram or until $F0 is sent in the data telegram.
Flashing of all display fields can also be activated by the H signal on functional
input F1 (priority compared to the commands).
For units provided with an LRD® display flashing is not possible.
Brightness
The brightness of all display fields can be reduced by means of the following
commands to the basic address of the control computer (protocol CR/LF):
$L1<CR><LF>
$L0<CR><LF>
Reduced brightness
Normal brightness
The brightness of the display fields can also be reduced with an H signal applied to
functional input F2 (priority compared to the commands).
For units provided with an LRD® display brightness reduction is not possible.
Blanking
The display can be blanked with the following command (priority over flashing)
(protocol CR/LF):
$B1<CR><LF>
$B0<CR><LF>
Decimal point
Blanking on
Blanking off
In the menu items A1...A8, the decimal point can be set for each display (for
numeric display fields only).
The decimal points may also be activated via the serial interface. For this purpose,
you must select setting 0 (no fixed decimal point) in the respective menu item.
Units with a LRD® display have no decimal points.
Leading zero suppression
In menu item C1…C8 you can set if leading zeros are to be displayed or
suppressed (for numeric display fields only). If leading zeros shoud be suppressed
for units with LRD® display and fixed decimal point (e.g. self-adhesive foil), the
corresponding position must be set in menu item A1…A8.
Display test
In menu item F, you can set whether a short-time display test is automatically
carried
out
in all display fields after power-on.
LED color
Devices with switchable LED color display the digits in red by default. If the
command $A… is sent in the data telegram, the subsequent digits are displayed in
the corresponding LED color:
$A0 = red, $A1 = green, $A2 = orange
Example: The display field H3 shall display the value 123 in green. The command
is 03$A1123.
Power-on reset
BAL C9302 SER EN 1.21
After switching the operating voltage on, minus signs are displayed in all display
fields to signalize that the unit is ready for operation. If a display test has been
preselected in menu item F, it will run beforehand.
11
Overflow
If more data are transmitted than can be displayed in a display field, o (overflow) is
displayed in all digits of the display field.
For alphanumeric display fields, o is displayed in all digits of the display field.
Switching output
The devices dispose of a switching output (relay) with potential-free change-over
contact (NC, NO, CO).
When setting OFF in menu item r, the switching output can be activated with the
following command:
$Q@1
$Q@0
Activate switching contact
Deactivate switching contact
The relay does not switch before the end of the telegram.
When setting 1, 2 or 4 in menu item r, the command $Q@1 causes a wiping pulse
at the switching output with a duration of 1, 2 or 4 seconds.
When setting A1, A2 or A4 in menu item r, each telegram to the basic address or a
field address causes automatically a wiping pulse at the switching output with a
duration of 1, 2 or 4 seconds.
The wiping function is suitable, for example, for activating optical and acoustic
signal transmitters.
The status indicator OUT of the control computer is lighted with active switching
output.

Notes on RS485 interface configuration
Menu settings
The interface format RS485 allows the settings
,
and
in the
menu item 1 (see chapter 4). The selected setting depends on whether the
protocol reply is to be sent by the unit:
If the unit should not send a protocol reply (normal case), application example A
applies for activating one or more units.
If a protocol reply is expected, a differentiation has to be made whether one single
unit or more units are to be activated. If one single unit is activated, application
example B is valid.
If several units are to be activated, a bus wiring is necessary. You have to
differentiate, if a 4-wire bus (full-duplex) or a 2-wire bus (half-duplex) is used.
Application example C applies for 4-wire bus and application example D applies for
2-wire bus.
Data lines
To achieve the highest possible interference immunity, the data lines of the RS485
have to be terminated on both ends. The required resistors are provided in the unit
and can be connected on the screw terminal strip with the jumpers S1 (Tx) and S2
(Rx) (see chapter 2, block diagram).
The polarization of the data lines must be ensured by means of the master.
For the data lines, you always have to ensure that:
BAL C9302 SER EN 1.21
ƒ
Shielded twisted-pair cables of sufficiently large cross-section are used.
ƒ
The shielding is connected on both line ends.
ƒ
For the signal ground (GND) use a wire pair short-circuited on both ends in the
data cable. The shielding may not be used as the signal ground.
ƒ
A twisted core pair is used each for Tx+ and Tx- and for Rx+ and Rx-. Nonobservance of this instruction causes the protective function of the twisted-pair
cable to be lost.
ƒ
Improperly terminated data lines cause faults during data transfer.
