Operating modes
Limit monitoring
Eight limit comparators are available to
monitor the limits.
Limits, differential values (hysteresis), limit
comparator functions (lk), texts and the
channels to be monitored can be pro-
grammed. The result of the monitoring is
fed to the open-collector outputs (1 — 3)
and the optional relay module (1 — 8) as
limit state (logic 0 or 1).
The different lk functions are:
lk 7:
The limit state is set to 1 when:
measurement > limit + upper differential.
lk8:
as lk7, but function is reversed.
Chart speeds
The LOGOPRINT 500 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 limits, the recorder switches
to the speed which has been programmed
under “limit operation”.
3. External operation
A signal on one of the logic inputs at the
back of the recorder switches to the speed
which has been programmed under “exter-
nal speed”.
4. Timed operation
The chart speed which is operative within a
programmable time span.
Graphic print-out
Measurement traces
Zoom (plot area)
In zoom operation, an enlarged recording is
made of a section of the full range of a
trace.
Presentation range (offset)
This parameter is used to define the pres-
entation range of a trace on the chart.
This assists the evaluation, in particular of
traces which are close to each other or
which overlap.
Peak value recording
The peak value recording can be switched
on or off for each channel.
In the switched-off state, the present value
of a channel is printed.
Since more values can be measured than
can be printed, the minimum and maxi-
mum values measured between two lines
to be printed are stored when the peak val-
ue recording is switched on. These mini-
mum and maximum values are printed
when peak value recording is activated.
Event traces
Eight event traces can be printed. Limit
monitoring (limit comparators) or the state
of the optional logic inputs can thus be
documented on the chart.
Text printing
Text printing is used for comments on the
recorded trace and for event recording.
Printing priorities can be assigned to texts,
to serve as abort criteria during simultane-
ous text printing requests.
Text printing can be separately configured
for each text, either time-optimized or dur-
ing continued recording of traces.
Text printing facilities:
- Time, date
- Scaling of the channels
- Channel numbers
- Change of chart speed
- Recording start/end text
- “Power on” and “power off” text
- Print text to check the printing system
and the service print
- 16 limit comparator texts 1
(eight for underlimit and eight for overlimit)
- 2 reports (calculate and print minimum,
maximum and mean values)
- Eight external texts 1 (extra code)
- 16 binary-linked external texts 1
(extra code)
- Event counter 1 (extra code)
1 These texts are buffered through a queue. As long
as the queue is not full, complete documentation
is assured.
Extra codes
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
measurements, to monitor operating states
and to transmit texts and values to the re-
corder.
Logic inputs
Eight logic inputs can be operated either
through floating contacts or by the follow-
ing voltage levels:
inactive: 0 — 5V / active: 20 — 35V
The voltage levels must be applied for
0.4sec.
Functions available include:
- External start/stop
- Activate external chart speed
- Text printing
- Start/stop external report
- Start scaling print
- Increment two event counters
- Key inhibit
- Event traces
Supply for 2-wire transmitter
An electrically isolated supply for a 2-wire
transmitter is available.
24V DC 45mA ± 5%
ER8 external relay module
The LOGOPRINT 500 can be equipped
with an ER8 external relay module (eight
relay outputs) to monitor infringements of
upper and lower limits. The relay outputs
are permanently assigned to the limit com-
parators. The assignment to the measure-
ment channels can be made freely through
the limit comparator parameter.
Contact rating:
3 A 250V AC 50Hz , or 3 A 30V DC
