1.6 Design and mode of operation
The device is based on a ceramic sensor element that is suitable for measuring
over-pressure and under-pressure. The pressure deforms the measuring membrane causing a change in resistance on the attached measuring bridge. This
change is evaluated by the device's electronics and transformed into the display, switch contacts or an standardised analogue output signal.
The optional output signal can be dampened, spread, inverted and transformed
via a table function even if it is non-linear. Overstepped limits can be visualised
with the LCD colour change display.
The unit is configured with a keyboard or by means of remote configuration from
a PC.

The two switching outputs are configured by four parameters respectively.
For the switch point 1 these are
Page 15
FISCHER Mess- und Regltechnik GmbH Commissioning | 3
BA_EN_MS13 15 / 32
• SP1 On
• SP1 Off
• SP1 delay
• SP1 Function
Accordingly for switch point 2:
• SP2 On
• SP2 Off
• SP2 delay
• SP2 Function
The function of the individual parameters is explained for both switch points using Switch point 1 as an example.
SP1 On defines the activation point, SP1 Off the deactivation point of switching
output 1. The values are shown in the valid unit and set accordingly. The values
are shown in the valid unit and set accordingly. Both parameters can be set independently over the entire value range.
The value range ranges from MBA – 50% to MBE + 50%. MBA stands for start
of measuring range and MBE for the end of the measuring range.
Example: Measuring range = 0 … 160 kPa
The value range for this measuring range is -80 kPa … +240 kPa.
Together, the two parameters SP1 On and SP1 Off determine the switch function of switching output 1:
• If SP1 On > SP1 Off, the output switches on, if the measured value exceeds SP1 On. It is only switched off again if the measured value SP1 Off is
undercut (hysteresis function).
• If SP1 On = SP1 Off, the output switches on if the measured value exceeds
SP1 On and off if the measured value undercuts the same value (SP1 Off).
• If SP1 On < SP1 Off, the output switches on, if the measured value lies
within these switch points: i.e:
SP1 On < Measured value < SP1 Off (window function).
SP1 Delay allows the reaction of the switch output to be delayed by between 0
and 1800 s. This parameter applies equally for switching on and off.
SP1 Function changes the function of the switching output 1. It is possible here
to define whether the contact should work as a open contact (NO) or a break
contact (NC).

range
Zero-pt. wind. Zero-point window ⅓ basic measuring
range
If there are unsteady pressure readings during operation, you can use the parameters Absorption and Zero-pt. wind. to stabilise the reading and the output
signal.
The parameter Absorption functions like a capillary throttle. However, it only
acts on the display, output signal and switch points (if these exist) but not on the
measuring cell itself.
You can set the response time to pressure jumps in the range 0.0 to 100 s.
Page 16

16 / 32 BA_EN_MS13
NOTICE
Response time
At maximum damping it can take over 2 minutes until the pressure jump from
the nominal pressure 100% to 0% is also shown as zero in the display.
In many cases, unsteady readings are not a problem during normal operating
mode, but this is not true for the idle state, i.e. if a measured value of zero is expected. The parameter Zero-pt. wind. is designed to solve this. Its value
defines a range around zero at which the measured value is set to zero (see
fig.).
The display only stops showing zero when the pressure leaves the set window.
When twice the window value is reached, the measuring pressure and the display correspond again. This avoids jumps in the display.

Zero-point window
Illustration16: Zero-point window
It makes sense to set the Offset (zero-point displacement) if, without differential
pressure (remove measuring line), the display shows a value that is not zero.
Before the offset correction, the zero-point window must be set to zero.
Select the Offset corr. parameter and correct the reading using the buttons
or
until zero is shown in the display.
When setting the offset, the current measured value is displayed. The zeropoint window is not active during the offset setting.

The transmitter output signal primarily depends on the sensed pressure. However, you have the option of adjusting the output signal to a large extent to suit
your requirements.

FISCHER Mess- und Regltechnik GmbH Commissioning | 3
BA_EN_MS13 17 / 32
NOTICE
Adjustment of the output signal
The basic measuring range (indicated on the type label) and the type of output
signal (voltage / current) are not variable.
The parameters MB start and MB end initially define the two pressures
between which the output signal will change at all. Both values are adjustable
across the entire basic measuring range. The set values also refer to the pressure in the respective unit. However, the signal values (current / voltage) for
‘Start of measuring range’ and ‘End of measuring range’ are fixed.
If MB start is smaller than MB end, this is called an increasing characteristic
curve; the output signal increases as the pressure increases.
If MB end is smaller than MB start, this is a decreasing characteristic curve and
the output signal decreases as the pressure increases.
The difference between the values MB start and MB end must be at least 25 %
of the basic measuring range.
You can select a unit other than the unit of the basic measuring range with the
parameter Unit. The user should remember however that not every unit is suitable. The conversion is automatic.
The parameter Limit allows the display, output and switching points to be limited to the range between Start of measuring range and End of measuring
range. This makes sense when content is measured to avoid "negative contents". If Limit is set to "no", those measured values that are greater or smaller
than the end values are shown.

Error signal Measuring range unit
The parameters min. output, max. output and error signal define the limits of
the output signal that may not be undercut or exceeded regardless of the pressure. The limit values take priority over the range defined by the MB start and
MB end parameters! These parameters primarily serve to prevent error mes-
sages in downstream systems caused by brief overstepping of measuring
ranges.
The parameter min. output is usually only used for devices with an output signal 4…20 mA because frequently values of below 3.8 mA are evaluated as error signals.
The max. output value can be used for the voltage and current to limit the maximum value.
The value defined via the parameter Error signal is issued if the device detects
an internal error and can no longer work correctly. It should be noted here that
not all potential errors and faults can be detected by the device itself.

3.3.5 Menu Level Function
The Function menu level is a variable menu whose appearance depends on the
value of the Function parameter. There are linear, square rooted and table functions
Linear function
The input signal is linear before being sent to the display and the output. The
range defined in the menu "Measuring" serves as the measuring range. If the
function LINEAR is active, the other menu items are cancelled.
Parameter name Description Value range
Function Function Value = linear
Square rooted function
Here, the input signal is square rooted before being sent to the display and the
output. This is necessary e.g. for flow measurements with differential pressure.
A free unit can be defined for the display. To do this, the start and end of the
display range and the number of decimal points are defined. It is also possible
to define the unit with 4 characters.

The display range is defined with the parameters MB decimal pl., MB start and
MB end. The user can select the configuration freely.
Using the parameter MB decimal pl., it is possible to select between a 5 or 6digit presentation. The resolution is not increased. Only an extra zero or two
zeros are added. This serves the correct display of larger values. The measuring range must be positive for the 6 digit presentation.
The MB unit gives the user the option of defining a completely independent
unit. Letters, numbers or special characters can be used. The unit can be max.
4 characters long.
If the function TABLE is selected, then it is also necessary to state the No. of
pairs. It is defined here how many pairs of values (support points) are used in
the table. A table is made up of at least 3, max. 30 support points.

The mots important parameter is Colour. A fixed colour can be defined for the
background colour here. There are also two auto-functions with colour switching
available. Alternatively, the background illumination can be permanently deactivated.
If permanent lighting is not required, the parameter Lighting time can be used
to define when the lighting should be switched off after the last time a button is
pressed. In addition to permanent lighting (0 s), automatic shut-down after 10…
600 s is also possible. The set time is only valid if the parameter Colour is not
set to "off".
Amongst other things, the legibility of the display depends on the temperature
and the reading angle. To ensure optimised legibility, the display can be adjusted using the parameter Contrast. When the contrast is changed, it is possible
that the display appears empty or almost completely black. In this case, the
contrast must be turned up or down.
Via the parameter Bar chart, the display can be switched between a display
where the measured value is either shown in large digits or the display shows
small digits and an additional barchart.
Auto1: Colour-change red to green
In the mode with the automatic colour switchover, it is possible to enter the required switch thresholds "red-green switchover", "green-red switchover".
The switching thresholds can be moved within the measuring range. The series
of switch points cannot be altered.

The parameter Hysteresis can be used to prevent fast and unwanted colour
changes. The hysteresis is set in the range 0.1... 10%.
NOTICE
Overlapping colour areas
Note: In the case of large hysteresis values, steps must be taken to ensure that
the ranges of the individual colours do not overlap. Otherwise it is possible that
the colour change may not function in the desired way.
The parameter Delay offers a further option to prevent unwanted colour
changes. The colour change here can be delayed between 0…1800 s.
The parameter Lighting can be used to define when the lighting should be
switched off after the last time a button is pressed. In addition to permanent
lighting, automatic shut-down after 10…600 s is also possible. The set time is
only valid if the parameter Colour is not set to "off". The lighting can be
switched on permanently with the value 0s.
The legibility of the display can be adjusted using the parameter Contrast.
When the contrast is changed, it is possible that the display appears empty or
almost completely black. In this case, the contrast must be turned up or down
again.
Via the parameter Bar chart, the display can be switched between a display
where the measured value is either shown in large digits or the display shows
small digits and an additional barchart.
Auto2: Colour-change red-yellow-green
In the Auto 2 mode with the automatic colour switchover, it is possible to enter
the required switch thresholds "red-yellow switchover", "yellow-green
switchover", green-yellow switchover, "yellow-red switchover".
The switching thresholds can be moved within the measuring range. The series
of switch points cannot be altered.

Unused range
If a range is not to be used, the associated switch thresholds (F1…F4) can be
set to the same value.
Example
The parameter Colour is set to Auto2. Only the green, yellow and red ranges
are required here. To fade out the lower ranges red and yellow, the switch
thresholds "red-yellow switching" and "yellow-green switching" are set to the
start of the measuring range.

The user menu can be switched to German, English, French, Spanish, Italian,
Portuguese or Hungarian using the parameter Language.
The menu items Software - Info and Config - Info provide information about
the device. This information helps to answer questions about the device quickly.
• The device type, controller ID and the firmware version is shown in the soft-
ware info.
• The basic measuring range, the defined output signal and existing contacts
are stated in the Config Info.
The Statistics provide information about the operating time and the relay
switching cycles from the time of delivery. The operating time is shown in days
(d) and hours (h)
A Password can be used to protect the menu against unauthorised access.
The password is a figure from 1 to 999. The input 0 means that no password is
active.
The password needs to be set if the user presses the button in normal mode to
enter the menu. If a wrong password is entered, the system automatically jumps
back to normal mode again. If no password is active, the display immediately
jumps to the menu.
NOTICE
Forgotten password
The user cannot restore a forgotten password. Please contact the manufacturer
in this case.
The user can load a saved configuration via the menu item Load config. This
means that a functional set of parameters can be loaded after trying out various
settings.
The menu item Save config. serves to save the existing parameters in a protected memory area. This is helpful if the settings of a functional device needs
to be optimised. Save config. and Load config. can be used to quickly restore
the initial status again.
NOTICE
Delivery condition
If the user has not yet saved a configuration, the default values (status on delivery) are loaded. In this case, any measuring range spreads or switch points are
reset and the device needs to be newly configured.
