DIP switch on the Modbus-communication board
Fig. 45: Communication board Modbus
1 Interface for LCD indicator and service port 2 DIP switches
The communication board is located behind the front housing
cover. The LCD indicator may have to be removed to provide
access to the DIP switches.
The DIP switches are used to configure specific hardware
functions. The power supply to the transmitter must be briefly
interrupted in order for the modified setting to take effect.
The interface for the LCD indicator is also used as the service
port for device configuration.
DIP switch Function
SW 1.1
Replacement mode (transfer system data)
On: Replacement mode active
Off: Replacement mode deactivated
SW 1.2
System data transfer direction
On: Transmitter -> sensor
Off: Sensor -> transmitter
SW 1.3
No function
SW 1.4
Format SensorMemory
Service function! - Risk of data loss in the device.
SW 1.5
Write protection switch
On: Write protection active
Off: Write protection deactivated
SW 1.6
No function
Write protection switch
If write protection is active, the device parameterization cannot
be changed. Activating and sealing the write protection switch
protects the device against tampering
Downloading system data, replacing the transmitter
When replacing transmitter components (communication
board), system data must be downloaded from the
SensorMemory.
Loading system data and the system data transfer direction is
activated using DIP switches SW 1.1 and SW 1.2.
See chapter "Repair“ in the operating manual.
6.3 Switch on the power supply
Switch on the power supply.
After switching on the power supply, the system data in the
SensorMemory is compared with the values stored internally in
the transmitter.
If the system data is not identical, it is balanced automatically.
The flowmeter is now ready for operation.
The LCD display displays the process display.
6.3.1 Checks after switching on the power supply
The following must be checked after commissioning the
device:
— The parameter configuration must correspond to the
operating conditions.
— The system zero point is stable. If this is not the case, a
zero point balance must be carried out (see chapter "Zero
point adjustment under operating conditions" on page 57).
6.4 Checking and configuring the basic settings
The device can be factory parameterized to customer
specifications upon request. If no customer information is
available, the device is delivered with factory settings.
