Figure 2-115 CFC chart for blocking of a pressure sensor during external fault
Setting Notes
General
The direct external trip functions are only enabled if addresses 186 EXT. TRIP 1 and/or 187 EXT. TRIP 2
have been set to Enabled during the configuration of the functional scope.
Addresses 8601 EXTERN TRIP 1 and 8701 EXTERN TRIP 2 are used to switch the functions individually
ON or OFF, or to block only the trip command (Block relay).
Signals included from outside can be stabilised by means of a delay time and thus increase the dynamic
margin against interference signals. For external trip functions 1 settings are done in address 8602 T DELAY,
for external trip function 2 in address 8702 T DELAY.
