Day defines the day of date. To change the day, select Day
with [Up]- and [Down] buttons and by pressing [OK] button the
day can be changed with [Up]- and [Down] buttons. Pressing
[OK] button confirms the new day.
Hour defines the hour of time. To change the hour, select Hour
with [Up]- and [Down] buttons and by pressing [OK] button the
hour can be changed with [Up]- and [Down] buttons. Pressing
[OK] button confirms the new hour.
Minute defines the minute of time. To change the minute,
select Minute with [Up]- and [Down] buttons and by pressing
[OK] button the minute can be changed with [Up]- and [Down]
buttons. Pressing [OK] button confirms the new minute.
9.2.6 MODBUS slave
If the CU 382 is used as a MODBUS-Slave, the connection
settings can be configured here.
The Address for each device must be unique in the MODBUS
environment. Parity and Baudrate defines the communication
parameters for RS 485 bus.
Address defines the MODBUS-ID. To change the MODBUS
address select Address with [Up]- and [Down] buttons and by
pressing [OK] button the Address can be changed with [Up]- and
[Down] buttons. Pressing [OK] button confirms the new Address.
Parity defines the parity of the communication. To change the
parity select Parity with [Up]- and [Down] buttons and by pressing
[OK] button the parity can be changed with [Up]- and [Down]
buttons. Pressing [OK] button confirms the new parity.
Baudrate defines the baudrate of the communication. To change
the baudrate select Baudrate with [Up]- and [Down] buttons and
by pressing [OK] button the Baudrate can be changed with [Up]-
and [Down] buttons. Pressing [OK] button confirms the new
Baudrate.
9.2.7 Update operating software
The operating software of the CU 382 can be updated in the field
with an USB stick easily. An image file image.hex has to be in the
root directory of the USB stick. If software update was successful,
a message will appear and the CU 382 will restarted.
9.2.8 Select language
To change the operating language of the CU 382 select the
desired language with [Up]- and [Down] buttons and by pressing
[OK] button the new operating language is confirmed.
9.3 Parameter / settings
In the Parameter settings menu, a parameter can be calibrated,
monitored, linked to an alarm, linked to an output and removed.
Also an overview of all settings of a parameter can be displayed.
.
9.3.1 Calibrate expert
Depending on the connected sensor several types of calibration
can be performed. If a local calibration cannot be performed to a
monitored parameter (e.g. actual operating software does not
support this feature) the CU 382 will display an user information.
Before calibrate be sure that the parameter value is stable!
Two different main types of calibration are available: Local or
Global.
By default Local is selected. This is the normal calibration
performed by the user during operation. The Global calibration is
used for factory calibration and therefore only performed by the
manufacture of the sensors.
With Mode three different local calibrations can be chosen:
Offset, Linear and Span. The availability of these modes depends
on the sensor type (see Table below and the manual s::can
sensors for further important information and details).
