3 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 is 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 is 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 entries.
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.
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).

BAL S302 ANA 4.01 7/19
EMC measures
The devices comply with the EU Directive 2004/108/EC (EMC Directive) and provide the required
interference immunity. Observe the following when connecting the operating voltage and data cables:
Use shielded data cables.
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.
The cable thickness must be properly assessed (DIN VDE 0100 Part 540).
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.
Neither excessively long cables nor cable loops may be placed inside the units.
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
conductive clamp
mouting plate
data line terminals
bare
metal surface
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.
Disposal
Units or unit parts which are no longer needed are to be disposed of in accordance with the
regulations in effect in your country.

The signal input is located on the screw-type terminal strip of the control computer.
The units can be activated by means of the analog signals 0...20 mA, 4...20 mA, 0... 10 V and 2...10
V.
The power supply and the signal inputs are gavanically isolated from the internal signal processing.
The operating voltage and the signal input are galvanically isolated from the internal signal processing.
Function inputs
The function inputs are located on the screw-type terminal strip of the control computer. They allow
reduction in brightness and flashing of the display, independently of commands via the analog
interface.
The function inputs 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

BAL S302 ANA 4.01 10/19
Serial interface
The devices have a serial interface RS422. It is located on the screw-type terminal strip of the control
computer and serves for reading out the display values.
Menu display
The parameterization of the units is carried out in a menu of the menu display. In normal mode, the
menu display corresponds to the main display. For devices with more than six positions, ◼◼ is
shown in the menu display in normal operation.
Menu buttons
The menu buttons are used to control the menu.
Switching output
The devices dispose of two switching outputs (relay) with potential-free make contact (output 1: CO1,
NO1; output 2: CO2, NO2).
Status indicators
The status indicators (LEDs) of the control computer have the following meaning:
OUT1Switching output 1 is active
OUT2Switching output 2 is active
Sensor voltage supply
An auxiliary voltage for supply of a sensor (24 V ±20 %, max. 50 mA, reference potential = M), which
is galvanically isolated from the operating voltage, is supplied by the units on terminal P.
Power supply
The screw-type terminals for the power supply are located on the power supply unit in the bottom
section of the housing. They have the following designations:
Devices for a power supply 115 V AC or 230 V AC L, N and PE
Devices for a power supply 24 V DC +, –and PE

BAL S302 ANA 4.01 11/19
5 Control
Input signal
The units can be activated by means of the analog signals 0...20 mA, 4...20 mA, 0... 10 V and 2...10
V. The input signal that activates the unit can be set under menu item 1.
Display area
Start and end value of the display area can be set in the menu items 2 and 3 as follows:
The initial value of the display area is set in menu item 2 and the final value is set in menu item 3. In
the display the menu item will appear (flashing) and the current setting. Also the decimal points flash
one after the other. The digit with the decimal point flashing can be set to the value requested with the
menu button [] .The minus sign is set in the left digit. It appears between 9 and 0.
The display shows a (overflow) in case of a display overrange and a (underflow) in case of a
display underrange.
Increment
The step width of quickly changing measuring signals or large scale values can be incremented in
menu item 4 to allow the reliable reading of the digit with the lowest order.
With setting 5, the position C1 shows only the figures 0 and 5. When setting 10, it shows a fixed zero.
With setting 50, the position C1 only shows a fixed zero, and the position C2 only shows the figures 0
and 5. When setting 100, the positions C2 and C1 show a fixed zero.
Averaging
The analog-digital converter has an integration period of approx. 0.25 s to allow quick measuring
processes to be recorded. In case of strongly superimposed measuring signals it may be useful to
show an average value over several integration intervals.
With setting 1 under menu item 5, no average value over several integration intervals is determined.
With setting 2, 4 or 8, an average value is determined over 2, 4 or 8 integration intervals.
Switching outputs
The units have two switching outputs (relays) with potential-free make-contacts (output 1: CO1, NO1;
Exit 2: CO2, NO2). The switching points can be set in the menu items 6 and 7.
The switching point of the output 1 is set in menu item 6 and the switching point of the output 7 is set
in menu item 7. In the menu display the menu item (flashing) and the current setting will appear. The
decimal point also light up successively. The digit with the decimal point flashing can be set to the
value requested by means of the menu key []. The minus sign can be set in the left digit. It appears
between 9 and 0.
The switching outputs are activated with a measured value equal to or higher than the switching point
set in the menu. They are deactivated as soon as the measuring value drops below the switching point
set by the hysteresis set in menu item 8. The corresponding status indicator of the control computer
(OUT1, OUT2) will light if the switching output is active.
The actual display value is compared. A decimal point set in menu item A is not considered.
The switching functions are not defined in the menu mode.
Wire break
If in menu item 1 the setting 4...20 mA is selected and if the input signal falls below the value of 3.6
mA, the unit interprets it as wire break, and the display shows 
The same applies if 2...10 V is selected in menu item 1 and the input signal falls below 1.8 V.

BAL S302 ANA 4.01 12/19
Serial interface
The devices have a serial interface RS422. It transmits the current display value as ASCII data
telegram containing 6 characters and the final CR/LF (xxxxxx<CR><LF>) in intervals of approx. 0.25
s.
The characters contain the current display value (right-aligned) including the algebraic sign (left-
aligned) or a possible overflow/underflow or wire breakage error. The leading zero suppression and a
decimal point, which was set in menu item A are ignored.
The data telegram always contains six characters and CR/LF independently of how many digits the
unit has. Unneeded characters are blank characters.
The parameters of the serial interface are: 9600 Bd, no parity, 8 data bits, 1 stop bit.
Decimal point
A fixed decimal point can be set in menu item A.
Devices with LRD® display have no decimal points.
Leading zero suppression
In menu item C it is set if leading zeros are to be displayed or suppressed.
Display test
In menu item F, you can set whether a display test is to be performed after the operating voltage is
applied.
Demo operation mode
If the setting ⚫ is selected in menu item F, random characters are displayed. In this case, it is
impossible to control the unit.
Stop the display
An H signal on the F3 function input stops the display but the analog input signal is still evaluated.
Flashing
Flashing of the display can also be activated by application of the H signal to functional input F1.
For devices provided with an LRD®display flashing is not possible.
Brightness
The brightness can be reduced with an H signal on function input F2.
For units provided with a LRD® display brightness reduction is not possible.

BAL S302 ANA 4.01 13/19
6 Parametrization
Menu
The parameterization of the devices is carried out in a menu in the menu display.
Menu operation
To start the menu, press both menu buttons simultaneously (approx. 1 sec.) until the first menu item
appears in the menu display. It is now possible to navigate in the menu as follows:
Next menu item Shortly press key []

To exit the menu shortly press the key [] in menu item U. Depending on the setting in menu item U
the settings made are either saved (set) or not saved (escape) or the factory settings are reset
(default).
Canceling the menu without saving the settings made is possible by pressing both menu buttons
simultaneously (approx. 1 sec.). It will occur automatically if 60 seconds pass without a menu button
being pressed.
Once the menu is closed, the device behaves in the same manner as when the operating voltage was
applied.
In the menu mode the character ✓appears in the main display. Control of the display is not possible.
Menu table
The menu items are displayed in the following menu table. The factory settings are marked with an *.
Individual menu items or settings can be suppressed in another menu item, depending on the unit
version or setting.
