Section 1-11
1.10
Fuse
A semiconductor fuse is used to prevent damage to the operating terminal. Once
the fuse has been activated, the device must be disconnected from the supply
voltage to allow the semiconductor fuse to regenerate. With an ambient tempera-
ture of 20
!
C, the regeneration takes about 20 seconds. The higher the ambient
temperature, the longer the regeneration period.
The semiconductor fuse is not designed to be replaced.
Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!
Electrostatic discharges can damage electronic components! ESD protective mea-
sures must be observed!
1.11
Application Memory
A 256 kByte flash memory is used as an application memory for each operating
terminal . This memory area is available to store the user application, the loadable
protocol driver, the fonts and the recipe data. The advantage of the flash memory is
that programming and deleting processes can be carried out directly in the termi-
nal.
Changing the application memory may only be performed by qualified and autho-
rized personnel!
