7 Changing the configuration
The configuration/parameter definition of the FMT400-VTS/-VTCS measuring systems can be modified via LKS
adapter (local communication interface) (Fig. 5-1).
This adapter is provided separately as an accessory and will be supplied completely with software and appro-
priate instructions.
To activate the configuration changes, the device must be restarted. To do so, use the command "restart reset"
or interrupt the power supply for approximately 10 seconds.
8 Fault messages
If faults occur (e. g. sensor leakage), the 0/4...20 mA output will accept the configured value, i. e. the following
settings will be possible in case of fault:
The following settings will be possible in case of fault:
• MIN < 3.5 mA
• MAX > 22.5 mA
Notice:
The standard setting in case of fault is 0...20 mA for (MAX.) and 4...20 mA for (MIN.).
These settings can be modified via the LKS interface and the respective configuration software.
Further fault messages (e.g. data error) can be received via the status function („Check function“, chapter 7).
The following parameters can be changed or imported:
• Read device data
display current settings
• Measuring range
