1. Brief description
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.

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
of AVG in the menu level DISPL, the result will be shown in the display and evaluated via the
alarms.
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.
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.
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

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/maxmemory. Under ActuA the measurand is shown, after this the display returns to the parameterised 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.

Three output signals are available 0-10 VDC, 0-20 mA and 4-20 mA. Select the desired signal
with this function.
Setting the final value of the analog output, Out.En:
Default: 10000
The final value is adjusted from the smallest to the highest digit with [▲] [▼] and confirmed
digit per digit with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit the device changes back into menu level.

Setting the initial value of the analog output, Out.OF:
Default: 00000
The initial value is adjusted from the smallest to the highest digit with [▲] [▼] and confirmed
digit per digit with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit the device changes back into menu level.
Overflow behaviour, O.FLoU:
Default: edge
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 EdGE, that means the analog
output runs on the set limits e.g. 4 and 20 mA, or to.OFF (input value smaller than initial value,
analog output switches on e.g. 4 mA), to.End (higher than final value, analog output switches on
e.g. 20 mA). If to.MIn or to.MAX is set, the analog output switches on the smallest or highest
possible binary value. This means that values of e.g. 0 mA, 0 VDC or values higher than 20 mA
or 10 VDC can be reached. With [P] the selection is confirmed and the device changes into
menu level.

Each setpoint (optional) can be linked up via 4 alarms (by default). This can either be inserted
at activated alarms AL1/4 or deactivated alarms ALN1/4. If LOGIC is selected, logical links are
available in the menu level LoG-1 and CoM-1. Access to these two menu levels is via LOGIC, at all
other selected functions, these two parameters are overleaped. Via On/OFF the setpoints can be
activated/deactivated, in this case the output and the setpoint display are set/not set on the
front of the device. The parameters Cal, Cal.of and CAL.en can only be used in accordance with
the semi-automatic calibration (Chapter 9. Sensor alignment). At Cal the relay switches during
sensor calibration, at cal.of during offset calibration and at Cal.en during the calibration of the
final value. With [P] the selection is confirmed and the device changes into menu level.

Dependency alarm 1, ALrM.1:
Default: actua
The dependency of alarm 1 can be related to special functions, in detail these are the current
measurand, the min-value, the max-value, the totaliser value/sum value, the sliding average
value, the constant value or the difference between the current measurand and the constant
value. If Hold is selected the alarm is hold and processed just after deactivation of HOLD. EHtEr
causes the dependency by an external signal via the digital input. With [P] the selection is
confirmed and the device changes into menu level.
Example:
By using the maximum value Alarm.1 = Max.va in combination with a threshold monitoring Fu-1 =
High, an alarm confirmation can be realised. Use the navigation keys or the digital input for
confirmation.

Threshold values / limit values, LI-1:
Default: 2000
The limit value defines the threshold, that activates/deactivates an alarm.
Hysteresis for threshold values, HY-1:
Default: 00000
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.
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.
Switching-on delay, ton-1:
Default: 000
For limit value 1 one can preset a delayed switching-on of 0-100 seconds.

To return the unit to a defined basic state, a reset can be carried out to the default values.
The following procedure should be used:
• Switch off the power supply
• Press button [P]
• Switch on voltage supply and press [P]-button until „- - - - -“ is shown in the display.
With reset, the default values of the program table are loaded and used for subsequent operation.
This sets the unit back to the state in which it was supplied.
Caution! All application-related data are lost.

8. Alarms / Relays
8. Alarms / Relays
This device has 8 virtual alarms that can monitor one limit value in regard of an undercut or exceedance.
Each alarm can be allocated to an optional relay output S1-S2; furthermore alarms can be controlled by
events like e.g. hold value or min/max-value.
Function principle of alarms / relays
Alarm / Relay x
deactivated, instantaneous value, min/max-value, hold-value, totaliser
value, sliding average value, constant value, difference between
instantaneous value and constant value or an activation via the digital
input
Switching threshold
Threshold / limit value of the change-over
Hysteresis

Working principle
Operating current / quiescent current
Operating current
By operating current the alarm S1-S2 is off
below the threshold and on on reaching the
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 short-term 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.

9. Sensor alignment offset / final value
9. Sensor alignment offset / final value
The device is equipped with a semi-automatic sensor calibration (s.300v, se.5a). A switching output
operates the trimming resistor, which exists in some sensors. An adjustment of offset and final
value takes place, after which the sensor can be used directly. Depending on parameterisation,
the calibration can be realized via the 4th key or via the digital input. It is possible to key during
the calibration steps. So, reference signals can be connected manually. However the calibration
will be interrupted after 30 seconds.
