1. Brief description
The panel meter instrument IMB2-2F is a 5-digit digital display with a 55 points bargraph
display and two galvanic isolated setpoints; designed for pulse signals respectively 2- and
3-wire sensors. The configuration happens via four 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 nominal presetting or setpoint presetting, 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 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 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.

5. Setting up the device
Menu level Parameterisation level
Selection of the input signal, tYPE:
Default: fre9u
If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to
be preset under rAnGE and is adjusted by application of the final value / initial value. If FrEqU
(factory calibration) is preferred, the final value needs to be entered under End and the final
frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and
under OFFSA the initial frequency. There is no application of the measuring signal. Confirm the
selection with [P] and the display switches back to menu level.
Setting the end value of the measuring range, END:
Default: 100e3
Choose between six different frequency ranges. Confirm the selection with [P] and the display
switches back to menu level.
Setting the final value of the measuring range, END:
Default: 10000
Set the final value from the smallest to the highest digit with [▲][▼]and confirm each digit with
[P]. A minus sign can only be parameterized on the highest value digit. After the last digit, the
display switches back to the menu level. If Sens was selected as input option, you can only
select between noca and cal.With noca, only the previously set display value is taken over, and
with cal, the device takes over both the display value and the analogue input value.

Setting the start/offset value of the measuring range, offs:
Default: 0
Enter the start/offset value from the smallest to the highest digit [▲][▼]and confirm each digit
with [P]. After the last digit the display switches back to the menu level. If Sens.F was selected
as the input option, you can only select between noca and cal.With noca, only the previously set
display value is taken over, and with cal, the device takes over both the display value and the
analogue input value.
Setting the decimal point, dot:
Default: 0
The decimal point on the display can be moved with [▲][▼]and confirmed with [P].The
display then switches back to the menu level again.

Menu level Parameterisation level
Setting of the pulse delay, dELAY:
Default: 0
With the pulse delay of 0–250 seconds (max), frequencies can be collected, which are even
smaller than by the predetermined measuring time of the device. If e.g. a delay of 250 seconds
is set, it means that the device waits up to 250 seconds for an edge, before it assumes a 0 Hz
frequency. Thus frequencies up to 0.004 Hz can be collected.
Adjustment of the optimum digital frequency filter, fi.frq:
Default: NO
If the optional filter is not activated by the adjustment „No“, frequences are ignored by the
adjusted frequency filter. Act on the assumption that the pulse-duty factor is 1:1. Accordingly
the minimal pulse duration is derived from the half of the time of oscillation. Use a filter of 10 Hz
or 20 Hz for contact bounce suppression.
Setting up the final value of the bargraph, ba.ENd:
Default: 1000
Set the final value from the smallest to the highest digit with [▲][▼] and confirm each digit
with [P]. A minus sign can only be parameterized on the highest value digit. After the last digit,
the display switches back to the menu level.
Setting up the initial value of the bargraph, baoff:
Default: O
Set the initial value from the smallest to the highest digit with [▲][▼] and confirm each digit
with [P]. A minus sign can only be parameterized on the highest value digit. After the last digit,
the display switches back to the menu level.
Selection of the bargraph functions, ba.fct:
Default: bar.fo
The bargraph can be displayed with the following possibilites: bars from left to right (top to
bottom) or bars from right to left (bottom to top), bars from the middle, a dot display of the
bargraph or a dot display with a permanently displayed midpoint. Confirm the selection by
pressing the [P] button. The display then switches back to the menu level again.

demanded signal is selected.
Setting up the final value of the analog output, Out.En:
Default: 10000
The final value is adjusted from the smallest digit to the highest digit with [▲][▼]and digit by
digit confirmed 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 up the initial value of the analog output, Out.OF:
Default: 00000
The final value is adjusted from the smallest digit to the highest digit with [▲][▼]and digit by
digit confirmed with [P]. A minus sign can only be parametrised on the highest digit. After the
last digit, the device changes back into menu level.
Threshold values / limit values, LI-1:
Default: 2000
For both limit values, two different values can be parameterized. With this, the parameters for
each limit value are called up one after another.
Hysteresis for limit 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 if display falls below / exceeds limit value, FU-1:
Default: high
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value
exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a
switching threshold of 100 and occupied with function „high“, the alarm will be activated by
reaching the threshold. If the limit value is allocated to „Low“, an alarm will be activated by
undercut of the threshold. See page 29.
Threshold values / limit values, LI-2:
Default: 3000
For both limit values, two different values can be parameterized. With this, the parameters for
each limit value are called up one after another.
Hysteresis for limit values, HY-2:
Default: 00000
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.
Function if display falls below / exceeds limit value, FU-2:
Default: high
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value
exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a
switching threshold of 100 and occupied with function high, the alarm will be activated by
reaching the threshold. If the limit value is allocated to Low, an alarm will be activated by
undercut of the threshold.
User code (4-digit number-combination, free available), U.CodE:
Default: 0000
If this code is set (>0000), all parameters are locked, if LOC has been selected before under
menu item run. By pushing [P] during operation mode for approx. 3 seconds, Code appears in
the display. To get to the unlocked reduced parameter, the user needs to enter the preset
U.Code. This code has to be entered before each parameterisation, until the A.Code (master code)
unlocks all parameters again.

Master code (4-digit number-combination free available), A.CodE:
Default: 1234
This code can unlock all parameters, if LOC has been activated before under menu item run.By
pushing [P] during operation mode for approx. 3 seconds, Code appears in the display. The user
can now reach all parameters by entering A.codE. Leaving the parameterisation, under menu
item run, the user can unlock them permanently by choosing ULOC or ProF. So, there is no need
for anew code entering, even by pushing [P] during operation mode again.
5.3. Programming interlock „run“
Activation / deactivation of the programming lock or completion of the standard
parameterisation with change into menu group level (complete function range), run:
Default: uloc
Use the navigation keys [▲][▼]to choose between the deactivated key lock Uloc (works
setting) and the activated key lock Loc, or the menu group level ProF. Confirm the selection with
[P]. After this, the display confirms the settings with "-----"and switches automatically to
operating mode. If Loc was selected, the keyboard is locked. To get back into the menu level,
press [P] for 3 seconds in operating mode. Now enter the CODE (works setting 1234) that
appears using [▲][▼]plus [P] to unlock the keyboard. FAIL appears if the input is wrong.
To parameterise further functions ProF needs to be set. The device confirms this setting with
„-----„and changes automatically into operation mode. By pressing [P] for approx. 3 seconds
in operation mode, the first menu group InP is shown in the display and thus confirms the
change into the extended parameterisation. It stays activated as long as ULOC is entered in
menu group RUN , thus the display is set back in standard parameterisation again.
