1. Brief description
The panel meter instrument MB3-3V is a 3-digit digital display with a 30 points bargraph display and
optional two galvanic isolated setpoints; designed for direct current/direct voltage signals. The configuration
happens via 4 keys at the front. The integrated programming interlock prevents unrequested changes of
parameters and can be unlocked again with an individual code. Optional the following functions are
available: a supply for the sensor, a digital input for triggering of Hold (Tara), two analog outputs and
interfaces for further evaluating in the unit. The electrical connection is done via plug-in terminals on the
back side.
Selectable functions like e.g. the recall of the min/max-value, an averaging of the measuring signals, a direct
threshold value regulation during operation mode and further measuring setpoints for linearisation, complete
the modern device concept.

4. Description of function and operation
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level was designed for the standard settings of the device. Only menu items which are sufficent to set the
device into operation are displayed. To get into the professional level, run through the menu level and
parameterise prf under menu item RUN.
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, supporting point treatment, totaliser function etc. In
this level function groups which allow an extended parameterisation of the standard settings are availabe. To
leave the menu group level, run through this level and parameterise ulc under menu item RUN.
Parameterisation level:
Parameter deposited in the menu item can here be parameterised. Functions, that can be changed or
adjusted, are always signalised by a flashing of the display. Settings that are made in the parameterisation
level are confirmed with [P] and thus saved. Pressing the [O]-key leads to a break-off of the value input and to
a change into the menu level. All adjustments are saved automatically by the device and changes into
operating mode, if no further key operation is done within the next 10 seconds.

Function chart:
4.1 Parameterisation software PM-TOOL:
Part of the PM-TOOL are the software on CD and the USB-cable with device adapter. The connection
happens via a 4-pole micromatch-plug on the back side of the device, to the PC-side the connection
happens via an USB plug.
System requirements: PC incl. USB interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and saved on the PC. The parameters can
be changed via the easy to handle program surface, whereat the operating mode and the possible selection
options can be preset by the program.
CAUTION!
During parameterisation with connected measuring signal, make sure that the measuring signal has no
mass supply to the programming plug. The programming adapter is galvanic not isolated and directly
connected with the PC. Via polarity of the input signal, a current can discharge via the adapter and destroy
the device as well as other connected components!

ModBus operating modes, b.mo:
Default: asc
There are two different types of operating modes: ASC and rtu. Modbus transfers no binary
cycle, but the ASCII-Code. Thus it is directly readable, however the data throughput is smaller
in comparison to the RTU. Modbus RTU (RTU = Remote Terminal Unit) transfers the data in
binary-coded. This leads to a good data troughput, even though the data cannot be evaluated
directly, as they first need to be transfered into a readable format.
Timeout, t.ou:
Default: 000
The monitoring of the data transfer is parameterised in seconds up to max. 100 seconds; there
is no monitoring with an entry of 000. The timeout is adjusted from the smallest to the highest

Overflow behaviour, O.fl:
Default: Edg
To recognise and evaluate faulty signals, e.g. by a controller, the overflow behaviour of the
analog output can be defined. As overflow can be seen either EdG, that means the analog output
runs on the set limits e.g. 4 and 20 mA, or t.OF (input value smaller than initial value, analog
output switches on e.g. 4 mA), t.En (higher than final value, analog output switches on e.g. 20
mA). If t.MI or t.MA is set, the analog output switches on the smallest or highest possible binary

threshold.
Quiescent current
By quiescent current the alarm S1-S2 is on
below the threshold and switched off on
reaching the threshold.
Switching-on delay
The switching-on delay is activated via an
alarm and e.g. switched 10 seconds after
reaching the switching threshold, a shortterm exceedance of the switching value
does not cause an alarm, respectively does
not cause a switching operation of the relay.
The switching-off delay operates in the
same way, keeps the alarm / the relay
switched longer for the parameterised time.

The interface RS485 is connected via a screened data line with twisted wires (Twisted-Pair). On each end of
the bus segment a termination of the bus lines needs to be connected. This is neccessary to ensure a secure
data transfer to the bus. For this a resistance (120 Ohm) is interposed between the lines Data B (+) and
Data A (–).

10. Safety advices
10. Safety advices
Please read the following safety advices and the assembly chapter 2 before installation and keep
it for future reference.
Proper use
The MB3-31-device is designed for the evaluation and display of sensor signals.
Danger!
Careless use or improper operation can result in
personal injury and/or cause damage to the equipment.
Control of the device
The panel meters are checked before dispatch and sent out in perfect condition. Should there be
any visible damage, we recommend close examination of the packaging. Please inform the
supplier immediately of any damage.
Installation
The MB3-31-device must be installed by a suitably qualified specialist (e.g. with a qualification
in industrial electronics).
Notes on installation
• There must be no magnetic or electric fields in the vicinity of the device, e.g. due to transformers,
mobile phones or electrostatic discharge.
• The fuse rating of the supply voltage should not exceed a value of 6A N.B. fuse.
• Do not install inductive consumers (relays, solenoid valves etc.) near the device and suppress
any interference with the aid of RC spark extinguishing combinations or free-wheeling diodes.
• Keep input, output and supply lines separate from one another and do not lay them parallel with
each other. Position “go” and “return lines” next to one another. Where possible use twisted pair.
So, you receive best measuring results.
• Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect the
screening on one side on a suitable potential equaliser (normally signal ground).
• The device is not suitable for installation in areas where there is a risk of explosion.
• Any electrical connection deviating from the connection diagram can endanger human life and/or
can destroy the equipment.
• The terminal area of the devices is part of the service. Here electrostatic discharge needs to be
avoided. Attention! High voltages can cause dangerous body currents.
• Galvanic isolated potentials within one complex need to be placed on an appropriate point
(normally earth or machines ground). So, a lower disturbance sensibility against impacted energy
can be reached and dangerous potentials, that can occur on long lines or due to faulty wiring, can
be avoided.
