Operating modes
Chart speeds
The recorder can be programmed with four
different operating modes for the chart
speed.
1. Normal operation
2. Limit operation
If the measurement goes above/below the
programmed limit values, the recorder
switches to the speed which has been pro-
grammed under “limit operation”.
3. External operation
A signal on one of the logic inputs at the
back of the recorder switches to the speed
programmed under “external speed”.
4. Timed operation
Chart speed which is operative within a
programmable time span.
Zoom (plot area)
In zoom operation, an enlarged recording is
made of a section of the full range.
Presentation range (offset)
This parameter is used to define the pres-
entation range of a trace on the chart.
This assists the evaluation of traces which
are close together or overlapping.
Text printing
Text printing is used for comments on the
recorded trace and for event recording.
Priorities can be assigned to the texts to
serve as abort criteria during simultaneous
text printing requests.
Text printing can be separately configured
for each text, either time-optimized or dur-
ing printing of the recording traces.
Text printing facilities:
-
Time, date
- Scaling of the channels
- Change of chart speed
- Recording start/end text
- Eight external texts
1
- 16 binary-linked external texts

- Eight relay texts 1
- Event counter 1
- Report
- Print test
- Service print
1. extra code 259 is required.
Extra codes
Logic inputs (259)
The eight inputs can be operated through
floating contacts or by the following volt-
age levels:
inactive 0 — 5V
active 20 — 35V
The voltages must be applied for 0.5sec.
Functions available:
-
External start/stop
- Chart speed change to “external
speed”
- Text printing
- Start/stop external report
- Start scaling print
- Event counter
Supply for 2-wire transmitter (259)
An isolated supply for a 2-wire transmitter
is available.
24V ± 5% DC 45mA
Serial interface for ER8 (259)
The external relay module ER8 can be op-
erated using the serial interface.
RS422/RS485 interface
This interface is intended for communica-
tion with higher-level systems
(e. g. bus system or PC).
It can be used to
-
read out the measurements,
- monitor operating states and
- transmit text and values to the
recorders.
Accessories
External relay module ER8
The recorder can be equipped with an ex-
ternal relay module ER8 (eight relay out-
puts) to monitor the infringement of upper
or lower limits. The assignment of the relay
outputs to the measurement channels is
freely programmable. The limit values are
set at the parameter level.
Relay function within the measurement
range: lk7, lk8
lk7:
Function: relay is energized when:
Measurement > limit + upper differential.
lk8:
As lk7, but relay function is reversed.
Position and width of the switching differ-
ential can be selected via the setup pro-
gram.
Contact rating:
3A, 250V AC 50Hz
3A, 30V DC
