2 Identifying the instrument version
2.1 Instrument description
The pen recorder provides 1, 2 or 3 channels for recording; the channels are isolated
from each other by optocouplers. Channel 1
can be used to write text in addition to the
signal trace. All three channels are zeroed
using Hall sensors.
A 24-place 5x 5 LED dot matrix display is
available for signal indication and programming. Operation is by eight keys on the instrument front and via a setup program using a PC. The configuration data are stored
permanently in EEPROM.
Input signals include resistance thermometers, resistance transmitters, thermocouples,
standard current and voltage signals. The
necessary linearisation is performed automatically. Eight logic inputs are available for
operating functions. An external relay module ER8 for rail mounting supplements the
pen recorder by eight switching outputs.
A 2-wire transmitter can be operated from
an isolated supply. The watchdog monitors
the recorder operation and triggers a restart
in case of a fault. On a power failure the
real-time clock is supplied by a lithium battery or a storage capacitor.
A summary of all recorder parameters is
given in the Appendix ( Section 12.6).

3.1 Location and climatic
conditions
The instrument location should as far as
possible be free from shock and vibration.
Stray electromagnetic fields, e.g. from motors, transformers etc., should be avoided
where possible.
The ambient temperature at the location
may be between –10 and+50 °C at a relative
humidity not exceeding 75 %, without condensation.
Corrosive air or fumes may interfere with the
function and life of the recorder.

4 Electrical connection
4.1 Notes on installation
❏ The choice of cable, the installation and
the electrical connection of the instrument must conform to the requirements
of VDE 0100 “Regulations on the Installation of Power Circuits with nominal
voltages below 1000V” or the appropriate local regulations.
❏ Work inside the instrument must only be
carried out to the extent described and,
like the electrical connection, only by
properly qualified personnel.
❏ If contact with live parts is possible when
working on the instrument, it has to be
isolated on both poles from the supply.
❏ Earth the instrument at terminal PE to
the earth conductor. This line should
have at least the same cross-section as
the supply lines. Earth lines should be
run in a star layout to a common earth
point which is connected to the earth
conductor of the supply. Do not loop the
earth connections, i.e. do not run them
from one instrument to another.
❏ Do not connect any additional loads to
the supply terminals of the instrument.
❏ The instrument is not suitable for instal-
lation in hazardous areas.
❏ Electromagnetic compatibility (EMC)
conforms to the standards and regulations listed under Technical Data.
Section 12.1
❏ Run input, output and supply lines sepa-
rately, and not parallel to each other.
❏ All input and output lines that are not
connected to the supply network must
be laid out as shielded and twisted
cables. The shielding must be grounded
to the earth potential on the instrument
side.
❏ Inductive loads in the neighbourhood of
the instrument, such as contactors or
solenoid valves, should be fitted with RC
modules for interference suppression.
❏ The instrument must be provided with
external fusing and disconnection. Depending on the supply voltage, the following fuse values apply for the external
fusing:
20 — 53V AC/DC, 48 — 63Hz
fuse 5A slow
93 — 263V AC, 48 — 63Hz
fuse 5A slow

6.2 Operating principle
The individual parameters and functions are
divided into three levels for clearer operation of
the recorder:
Basic status
Basic status of the recorder with signal acquisition, recording, indication and processing.
The display shows, depending on setting:
- instrument designation, date and time
(the time can be switched off via the parameter parameter level display time)
- one channel and its measurement as a
number or bargraph
- or system error messages.
The display can be altered during recording
using the keys h and R.
If there is a system error message, it is
shown flashing at regular intervals instead
of the current display.
Operating level
At this level, signal acquisition and processing remain activated.
The following parameters can be altered at
the operating level:
-chart speed
- print test
- service print.
A summary of all parameters of the recorder
is given in the Appendix.
Section 12.6
22
6 Preparation
Parameter level
The parameter level is protected by a codenumber to prevent unauthorised access.
H
If a wrong codenumber is input, the individual parameters can be viewed, but not programmed.
Following input of the correct codenumber,
the recorder interrupts signal acquisition
and recording at this level. Statistical reports
are re-started on leaving the parameter level.
There are two different
codenumbers:
- Codenumber for limited
parameter set
- Codenumber for complete
parameter set
Section 8.2.4
Section 12.6
Section 7.9
The following parameters are altered at the
parameter level:
- language
- date and time
-summer time
- display brightness
-relay limit
- display time

The levels, parameters and subparameters
are arranged in a tree structure. Starting
from the basic status the program branches
to the individual levels and from there into
the corresponding parameters, and also
into any sub-parameters.
To alter a certain parameter, run through the
relevant levels up to this parameter.

Where there are no further sub-parameters,
E transfers all the data of the parame-
ter to the memory.
Aborting programming
Programming can be aborted within a parameter by pressing the key e.
If the last sub-parameter has not yet
been entered, the parameter data
which have already been edited are
discarded. The old sub-parameters
are retained.
Error messages during programming
If there are error messages during programming due to incorrect inputs, these have to
be acknowledged with E before programming can be repeated.

6 Preparation
Selection
Selection consists of a list of several options.
Three keys are used to select an option:
* select option with the h and R key
* enter selection with E
Value/text input
Five keys are used to input values:
* select the digit to be altered with the
l and r keys
* increment and decrement the selected
diget with the h and R keys
* shift the decimal point with the S key
* enter value input with E
An incorrect input produces an error
message on the display.
Section 12.2
The error message must be acknowl-
edged with
A new value can then be entered.
Five keys are used to input text:
* select the character to be altered with the
E.
l and r keys
* select the new character with the
h and R keys
(rapid character selection with the S key)
* acknowledge text input with E

7 Text printing
The pen recorder can print text in addition
to the trace using the fibre pen of channel 1.
Text printing is used for comments on the
trace and for event recording. The characters are written in dots on a 9 x 7 matrix.
7.1 Printing priorities
There are various types of text which are assigned priorities in the setup program.
These priorities determine abort criteria
where printing of several texts is required
simultaneously.
The following applies in the explanation
below:
- text 1 = text with high priority
- text 2 = text with low priority
If text 2 is being printed while there is a re-
quest for text 1, the printing of text 2 is interrupted and text 1 is printed.
If there is a request for text 2 while text 1 is
being printed, text 2 is output after text 1 has
been printed.
