1. Brief description / 2. Safety advices
The panel meter instrument M3-34H is a 5-digit device for AC current / AC voltage signals (TRMS) and a
visual threshold value monitoring via the display. The configuration happens via three keys at the front or by
the optional PC software PM-TOOL. The integrated programming interlock prevents unrequested changes
of parameters and can be unlocked again with an individual code. Optional the following functions are
available: one analog output and interfaces for further evaluating in the unit.
With help of the two galvanic isolated setpoints (optional), free adjustable limit values can be controlled and
reported to a superior master display.
The electrical connection is done via plug-in terminals on the back side.
Selcetable functions like e.g. the recall of the min/max-value, an averaging of the measuring signals, a
nominal presetting or setpoint presetting, a direct threshold value regulation during operation mode and
further measuring setpoints for linearisation, complete the modern device concept.
2. Safety advices
Please read the following safety advice and the assembly chapter 2 before installation and keep it for future
reference.
Proper use
The M3-34H-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 M3-34H-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 a 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.

5. 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 prof under menu item RUN.
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 uloc 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 safed. 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.

5. Setting up the device
User code (4-digit number-combination, free available), U.CodE:
Default: 0000
If this code was set (>0000), all parameters are locked for the user, if LOC has been selected
before under menu item run. By pressing [P] for 3 seconds in operation mode, the display
shows COde. The U.Code needs to be entered to get to the reduced number of parameter sets.
The code has to be entered befor each parameterisation, until the A.Code (Master code) unlocks
all parameters again.
The same applies to LI-2 !
Function for threshold value undercut / exceedance, Fu-1:
Default: high
A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value
exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function High, an alarm is activated by reaching of the threshold level.
If the threshold value was allocated to Low, an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
Master code (4-digit number-combination, free available), A.CodE:
Default: 1234
All parameters can be unlocked with this code, after LOC has been activated under menu item
run. By pressing [P] for 3 seconds in operation mode, the display shows COde and enables the
user to reach all parameters by entering the A.codE. Under run the parameterisation can be
activated permanently by selecting ULOC or ProF, thus at an anew pushing of [P] in operation
mode, the code needs not to be entered again.
Hysteresis for limit values, HY-1:

Arithmetic, ArItH:
Default: n0
With this function the calculated value, not the measuring value, is shown in the display. With
no, no calculation is deposited. With [P] the selection is confirmed and the device changes into
menu level.
Minimum constant value, con.mi:
Default: -i9999
The minimum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Definite contstant value, const:
Default: 0
The constant value can be evaluated via the alarms or via the analog output, like the current
measurand. The decimal place cannot be changed for this value and is taken over by the
current measurand. Like this a setpoint generator can be realised via the analog output by this
value. Furthermore it can be used for calculating the difference. At this the constant value is
substracted from the current measurand and the difference is evaluated in the alerting or by the
analog output. Thus regulations can be displayed quite easily.
Zero point slowdown, ZErO:
Default: 00
At the zero point slowdown, a value range around the zero point can be preset, so the display
shows a zero. If e.g. a 10 is set, the display would show a zero in the value range from -10 to
+10; below continue with -11 and beyond with +11. The maximum adjustable range of value is
99.
Sliding average determination, AVG:
Default: 1.0
Here, the number of the meterings that need to be averaged is preset. The time of averaging
results of the product of measuring time SEC and the averaged metering AVG. With the selection

Maximum constant value, con.ma:
Default: 99999
The maximum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Brightness control, Light:
Default: 10
The brightness of the display can be adjusted in 16 levels from 00 = very dark to 15 = very
bright via this parameter or alternatively via the navigation keys from the outside. During the
start of the device the level that is deposited under this parameter will always be used, even
though the brightness has been changed via the navigation keys in the meantime.
Display, dISPL:
Default: actua
With this function the current measuring value, min/max value, totaliser value or the process-
controlled Hold-value can be allocated to the display. With [P] the selection is confirmed and
the device changes into menu level.

Assignment (deposit) of key functions, tASt:
Default: no
For the operation mode, special functions can be deposited on the navigation keys [▲] [▼], in
particular this function is made for devices in housing size 48x24mm which do not have a 4th
key ([O]-key). If the min/max-memory is activated with EHtr, all measured min/max-values are
saved during operation and can be recalled via the navigation keys. The values get lost by
restart of the device. If the threshold value correction LI.12 or LI.34 is choosen, the values of the
threshold can be changed during operation without disturbing the operating procedure. With
tArA the device is tared to zero and saved permanently as offset. The device confirms the
correct taring by showing ooooo in the display. Set.tA switches into the offset value and can be
changed via the navigation keys [▲] [▼]. Via totAL the current value of the totaliser can be
displayed, after this the device changes back on the parameterised display value. If tot.rE is
deposited, the totaliser can be set back by pressing of the navigation keys [▲] [▼], the device
acknowledges this with ooooo in the display. The configuration of EHt.rE deletes the min/max-
memory. Under ActuA the measurand is shown, after this the display returns to the para-
meterised display value. If AbS.UA (absolute value) was selected, the display shows the value
that has been measured since voltage connection, without consideration of a previous taring.
Via selection L1.1, L1.1-2, li.1-3, l1.1-4 threshold values can be addressed via the navigation keys;
they can be changed digit per digit or taken over by pushing the [P]-key. The adjustment is
taken over directly, an excisting limit value monitoring and the current measurement will not be
influenced by this. If no is selected, the navigation keys are without any function in the operation
mode.
