When devices are working in a network, these networks must be designed in
such a way that malfunctions in individual nodes can be detected and shut
down.

Safety precautions must be taken both in terms of hardware and software, so
that a line break or other interruptions to signal transmission, such as via the
bus interfaces, do not cause undefined states or loss of data in the
automation device.

Appropriate use

The SCOUT55 with the connected transducers may be used for measurement
and directly related control and regulation tasks, only. Any other use is not
appropriate. To ensure safe operation, the transducer may only be used

2.7 Synchronisation

If several devices are used right next to one another or if their cables run
parallel, the devices should be synchronised. To achieve this, one device
must be set to Master and all the others (max. seven) to Slave. The setup with
jumpers on the amplifier motherboard is described in Chapter 2.2.2 . As well
as these settings, the devices must be linked together for synchronisation.

2.8 Connecting the serial interface

On the back of the device, there is an RS232 serial interface for connecting a

computer or a terminal.

When connecting a printer, a simple line printer needing no
more than 4 seconds to print a line is sufficient. The printout
has 12 columns. This corresponds to a line length of 132
characters. Select the measured values to be printed as
described in Chapter 3.5.9.

When connecting a computer, it is possible to enter into dialogue with the
SCOUT 55.

You can use control commands to make all the device settings and query the
measured values. An overview of the interface commands has been compiled
in another part of the Operating Manual “SCOUT 55, Part2: Operation by

computer or terminal”.

3.5.3 Load/Save in parameter set (PARAM. SET)

The current device amplifier settings can be saved power fail safe in eight
parameter sets

and later queried.

When switching from the programming operating mode to measuring mode,
you will be asked whether or not the change is to be saved. This is described
in Chapter 3.4.3 .

Parameter sets can also be activated/recalled by remotes (PARACODE1...2,
see Chapter 3.5.8).

EXCITATION:

The excitation voltage for the transducer is selected.

INPUT:

Depending on which excitation voltage is chosen, the input range
(approximate measuring range) can be selected for the transducer type.

Input range UB = 2.5 V UB = 1 V

I "4 mV/V "10 mV/V

II "40 mV/V "100 mV/V

III "400 mV/V "1000 mV/V

AUTOCAL:

Depending on the application and on the stability requirement, you can start
an autocalibration cycle. This lets you correct zero point and full scale value
drift and the long-term constancy of the measuring amplifier.

Possible settings:

ON Autocalibration switched on

OFF Autocalibration switched off

ONCE

Autocalibration is run once, as soon as you confirm it with
Autocalibration stays on/off, depending on the state previously
selected.

CAUTION

If you need the analogue output signal for continuous monitoring, you
must switch autocalibration off.

Reason: no measured values are recorded during the autocalibration
cycle. This produces a “monitoring gap” (interval approx. 5 min.,
duration approx. 1s), which is undesirable if not dangerous during
production processes.

4 Example

The following example uses a measurement task to show you the functionality
of the device and the required settings.

Problem definition:

The forming process in a press is to be monitored in order to obtain uniform
product quality. The maximum force exerted by the press is to be recorded in
each cycle. To guarantee the production process, this maximum force must
fall between the lower (F1) and upper (F2) force limit.

Solution:

The force characteristic measured with an S.G. force transducer (e.g.
C9B/10kN; 1 mV/V) is amplified and evaluated by the SCOUT 55. The peak
value store (maximum) is used to record the maximum force and it is
evaluated with two limit switches with regard to the lower and upper limits. An
additional limit switch is provided for overload protection (emergency shut
down) of the machine.
A PLC takes over the control of the process. As well as the control commands
for the press, it gives the SCOUT 55 a start signal to begin the pressing cycle
and once the process has finished, logically links the limit switch outputs to
the “Good/Bad evaluation”.
The start signal from the PLC clears the contents of the peak value store
through the SCOUT 55 control input. To prevent unintentional modifications,
during measurement, only the “Display signal selection” button is enabled for
the machine operator on site.
The parameter setups are protected against unauthorised modification by a
password.
Device control through the remotes (remote control) must be activated.

Limit2 1 1 0

Choose the following settings:

Limit1 Checks whether the lower force limit has been reached.

The input signal is the output of the peak value store
(maximum value). If limit LV1 is exceeded, a High signal is
generated. A positive switch direction must be set with
positive output logic.

Limit2 Checks whether the upper force limit has been reached.

The input signal is the output of the peak value store
(maximum value). If limit LV2 is exceeded, a Low signal is
generated. A positive switch direction must be set with
positive output logic.

51

Limit3 Checks whether the maximum load limit of the machine is

exceeded (emergency shutdown function). The input signal
is the gross measured value. If limit LV3 is exceeded, a
High signal is generated. A positive switch direction must
be set with positive output logic.

PVS1 Records the maximum peak value of the force

characteristic. Must be enabled, the envelope function must
be deactivated. The input signal is the gross measured
value. PVS1 is cleared with remote 1 by switching to
instantaneous value.

Remote 1 Clears the contents of the peak value store. The function

PVS1 INST must be selected. The remote must be

activated.
