2.2 Basics of operation
In order to keep the operating and programming of the printing recorder clear
and simple, the individual parameters and functions are divided into several
levels:
- Basic status
- Operating level (S-level)
- Parameter level (P-level)
- Configuration level 1 (C1-level)
- Configuration level 2 (C2-level)
- Configuration level 3 (C3-level)
12
The levels, parameters and sub-parameters are arranged as a tree structure.
Starting from the basic status, it branches out into the individual levels, and
from there further into the corresponding parameters and, if available, subparameters.
If it is necessary to alter a certain parameter, then step through the relevant
level until this parameter is reached.
Pressing E starts the editing process.
If a parameter has several sub-parameters, these can also be accessed by
pressing E.

Key inhibit If the printing recorder is fitted with the extra code “logic inputs”, then it is
possible when a selected logic input is closed, in connection with the parameter Configuration level 3
The following keys or functions can be inhibited in the basic status:
- e chart fast-forward, when the recording mode is stopped
- S start/stop of recording mode
- F function key, to activate scaling print-out
- h + R change from the basic status to the operating level
Even when the keys are inhibited, certain functions are still possible in the ba-
sic status:
- l + r switch error messages on/off
- h , R channel selection
- E switch between cyclic and static display
Key inhibit has no effect as long as the printing recorder is in the basic status
or in one of the configuration levels. On leaving these levels the keys will be inhibited if the logic input is set. It is only possible to call up the operating or
configuration levels again after opening this logic input.

Basic status After the supply voltage has been applied, the printing recorder will be initial-
ised and is then in the basic status. Measurements are made, processed, and
recorded.
The 24-character LED dot-matrix display can show:
- instrument designation (name), date and time
(the time can be switched off via the parameter Parameter level
time)
- channel number and measurements (incl. units) of all active channels
(in pairs)
- channel number, name and measurement (incl. units) of all active channels
(sequentially)
- status and error messages
-interface texts
v Section 10.6 “Interface (RS422/RS485)”
- customer-specific texts
The display can be either cyclic or static:
Î Display
Cyclic display
The printing recorder switches automatically to the next display after about
3sec.
Static display
In the basic status, the static display is activated and de-activated with E.
If it is activated, then the present display remains, and is regularly updated.
In the basic status, the information in the display can be changed over with the
h and R keys.
Status and error messages will be identified in plain language by a regularly
flashing display, instead of the present display.
The display of status and error messages can be inhibited, or activated again,
by pressing l + r .
If a measurement is outside the valid range of the A/D converter
(out-of-range), or if a probe break has been detected, then the
character combination “>>>>>>” will appear in place of the value.
The recording can be stopped or re-started with the S key. In the stop status
“STOP” will flash in the LED dot-matrix display.
Using the e key, in the stop status, activates the chart fast-forward.
Pressing the F key for at least 4 sec will restart the scaling print-out.
The operating level can be accessed by pressing the h + R keys simultane-
ously.

Parameter
level (P-level)
The parameter level can be accessed from the operating level with the aid of
the h + R keys, from the configuration level 1 by using e.
The parameter level and configuration levels are protected by a four-figure
code number.
There are two different code numbers:
- Code number for the restricted parameter set (factory setting 9200)
- Code number for the full parameter set (factory setting 9210)
The parameters which belong to the restricted parameter set are defined in the
setup program under Edit
Here, parameters which are not needed for the application, or only have to be
programmed once, can be appropriately marked. They will no longer be displayed on the recorder after the new setup has been transferred.
If one of the two code numbers is entered, then
- signal acquisition and
-recording
will be interrupted.
Furthermore
Î Instrument operation …
- events will no longer be recorded,
- reports will be aborted and reset,
- limits will no longer be monitored,
- the Code for the mathematics module will no longer be applied,
- the fault signal output will be set to fault, and
- all other outputs will remain in their last state.
The parameters can now be programmed.
If the wrong code number is entered, then the recorder will remain
in the normal mode. Signal acquisition, processing and recording
are still active.
The parameters can be looked at, but not programmed.
The code numbers can be altered through the setup program

2. The parameter can only be edited if the extra code “RS 422”
or “RS 485” has been implemented in the recorder.
3 Operation and visualisation
The printing recorder has a large variety of possibilities for presenting the
measurements acquired at the signal inputs on the paper, for monitoring them,
and for control.
The functions are available for:
- limit monitoring through limit comparators
-open-collector outputs
- different chart paper speeds
- graphics printing
- text printing
3.1 Limit monitoring by limit comparators
8 limit comparators are available for monitoring limits. They are set up through
the parameter Configuration level 1
rameters can be used to establish the limit values, switching differential (hysteresis) limits, texts, limit comparator functions (lk) and the response to a
probe break.
Î Limit comparator. Appropriate sub-pa-
The texts are printed out when the values go out-of-range or exceed the differential values, as described in the section on text printing.
v Section 3.5.4 “Limit comparator texts, external text, binary-linked external
text”
The limit comparators produce a logical 0 or 1 as output. The sub-parameter
“LK-function” also decides what the result of the limit state is.
LK function: lk7
23
3 Operation and visualisation
LK function: lk8
As well as producing the text print-out, the results from
- limit comparators 1 to 3 can be fed to the open-collector outputs 1 to 3,
and/or
- those from limit comparators 1 to 8 to the relay outputs 1 to 8 (option).
The relay outputs are available as an option (extra code ER8).
v Section 10.3 “External relay module ER8”
The state of the limit comparators can be documented by using
the event traces on the chart paper.
v Section 3.4.2 “Event traces”
The response of the limit comparators to out-of-range measurements or a probe break can be defined with the parameter Config-
uration level 1 ➔ Limit comparator ➔ Probe break.
The limit values can be printed out in the form of limit marks (“l”)
together with the scaling.
v Section 3.5.8 “Scaling”
24
3 Operation and visualisation
3.2 Open-collector outputs
The printing recorder is equipped with four open-collector outputs. The outputs 1 to 3 have a fixed assignment to the limit comparators 1 to 3. Output 4 is
used as a fault signal output. The outputs can be activated by using the parameter Configuration level 2
Fault output The fault signal output can be used to indicate a fault. During correct operation
of the printing recorder this output is active. In the event of a fault or disturbance, or if the status in the parameter Configuration level 2
is OFF, it becomes inactive (open).
The following causes will lead to a fault signal:
- Chart paper end
- Power off
- The battery of the recorder is discharged
- No communication with the external relay module ER8
- Fatal errors

To avoid excessively frequent chart speed changes, a switching
differential (hysteresis) of 0.5% is applied to the switching level.
The switching differential is referred to the scaling and zoom.
Se = scaling end
Sa = scaling start
Ze = zoom end
Za = zoom start

3.4 Graphic print-out
The printing recorder is fitted with a print head which always has 6 colour
pens, regardless of the number of channels. For the 3-channel version the colour sequence is: violet, red, black, violet, red, black. For the 6-channel version
it is: violet, red, black, green, blue, brown. This means that in the 3-channel
version the colours last twice as long. When using the setup program, if colours are assigned to a 3-channel recorder which are not available (green, blue,
brown), they will automatically be replaced (violet, red, black). The printing of
measurements and texts is always made in the same direction (unidirectional
printing).
The time which is needed to print out one line depends on the number of
points which have to be printed in this line. If the maximum number of points
are printed, then about 12 seconds are required for one line.
As the chart speed increases, more and more measurements, and so more
and more lines, have to be printed. So the printer must reduce the time which
it needs to try and print a line as the speed increases. These times can be seen
in the following table.

Up to a speed of 120mm/h every line can be printed in the time available,
since there are never more than 12 seconds required. At higher speed, if the
time taken to print a line is longer than the value in the table, then the lag is
compensated for by speeding up to the next line.
Example:
At a speed of 300mm/h the printing recorder attempts to print a line every 6
seconds, according to the table. But it needs 9 seconds to print a line. This is
compensated by increasing the speed by 50% for the next line.
The recorder has been so developed that the printed traces are always as visible as possible. For instance, an alternating print of the different colours
avoids a mixing and waste of colour if the measurements are the same.

Example:
If three traces lie on top of one another, then the alternating print pattern ensures that no point has a multiple print, but that each channel uses one point
at a time, sequentially.

3.4.1 Measurement traces (signal traces)
In the factory setting, all the measurement traces are printed over the full chart
width. The parameters “zoom” and ”presentation range” offer the possibility of
altering the print-out.
Zoom
(plot area)
Zoom operation is used to record a section of the complete measurement
range in an enlargement. Zoom operation is activated by the parameter Con-
figuration level 1
The values to be entered for the start (ZOOM-START) and end (ZOOM-END)
are made in %, and can be calculated as follows:
Mk = smallest measurement to be recorded
Mg = largest measurement to be recorded
Sa = scaling start
Se = scaling end
The difference between start and end values must be at least 10%.
Example:
The selected input signal is a voltage in the range 0 — 10V, and the scaling is
set to the range 0 — 2000m/h. The section of the range from 500 — 1500m/h
is to be displayed.
Î Zoom.
Presentation
range (offset)
Peak value recording
This parameter can be used to determine a range of the chart paper on which
the trace will be recorded. Either the complete chart paper width of 100 mm
can be used, or just a portion. In this way it can be arranged that all the channels are presented next to one another (strip recording). The presentation
range is activated by the parameter Configuration level 1
The printing recorder can acquire considerably more values than it can print.
At a chart speed of 20 mm/h, for instance, approximately only every 24th
measurement is recorded on the chart. The peak value recording function can
deal with this situation.
Peak value recording = OFF:
When the peak value recording is switched off, the latest value present at the
instant of printing is recorded on the chart.
Peak value recording = ON:
When the peak value recording is switched on, the minimum and maximum
measurements are stored internally between two lines which are to be printed.
Î Offset.

3 Operation and visualisation
These minimum and maximum values are printed when peak value recording
is activated. One advantage of the peak value recording is that at least an impression of the measurement trace on the chart can be gained, even at slow
chart speeds and after text printing in the “Interrupt measurement trace”
mode.
The peak value recording can be switched on and off for each channel by using the parameter Configuration level 1
Î Peak value recording.
Colour
assignment
The colours which are used to print the traces can be set with the aid of the
setup program.
In the basic status, for a 3-channel recorder, the colours violet, red and black
are assigned to the channels 1 — 3.
When using a 6-channel recorder, the colours green, blue and brown are also
used, for the additional channels 4 — 6.
3.4.2 Event traces
In addition to the measurement traces, the printing recorder offers the possibility of recording up to 8 event traces. The sources for the events can be the
limit comparators as well as the logic inputs (extra code).
The source selection and trace selection are made by the parameter Configu-
ration level 3
The setup program can be used to select the start position of the event traces
on the chart paper, between 0 and 100%.
If not all the event traces are selected, then a gap will appear at the corresponding positions. This means that every trace has the same spacing from
the defined start position.
Î Event traces.
Colour
assignment
30
In the 6-channel version, the colours violet, red, black, green, blue, brown, violet and red are assigned to the event traces 1 — 8. In the 3-channel version
the colours green, blue, brown are replaced by violet, red, black.
The colours can be changed with the aid of the setup program.
