1. Brief description
The panel meter M2-11 is a 5-digit device for direct current/direct voltage signals and a visual
threshold value monitoring via the display. The configuration happens via four front keys or
via the optional PC software PM-TOOL. An integrated programming interlock prevents
unrequested changes of the parameters and can be unlocked again by an individual code.
Optional the following functions are available: a supply for the sensor, a digital input for
triggering of Hold (Tara) or an analog output for further processing in the equipment.
By use of the two optional galvanic isolated setpoints, free adjustable threshold values can
be controlled and reported to a superior master display.
The electrical connection is carried out on the back side via plug-in terminals.
Selectable functions like e.g. the request of the min/max-value, an average determination of
the measuring signals, a nominal preset respectively setpoint preset, a direct change of
threshold value in operation mode and additional measuring supporting points for
linearisation complete the modern device concept.

1. After removing the fixing elements, insert the device.
2. Check the seal to make sure it fits securely.
3. Click the fixing elements back into place and tighten the clamping screws by hand. Then
use a screwdriver to tighten them another half a turn.
CAUTION! The torque should not exceed 0.1 Nm!
The dimension symbols can be exchanged before installation via a channel on the side!

Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level is 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 under menu item .
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, setpoint 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
under menu item .
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. By pressing the [O]-key
(zero-key) it 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 it changes into operating mode, if no
further key operation is done within the next 10 seconds.

4. Function and operation description
4.1 Parameterisation software PM-TOOL:
Part of the PM-TOOL are the software on CD and an 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!
