Section 9: Set-Up Routines
9.1.8 Fail-safe
This function configures the actuator action in case of loss of the 4 - 20 mA input or bus
signals. This action only takes place if the local selector is in REMOTE and if the positioning
function or the bus interface are active. When the 4 - 20 mA or bus signal is restored, the
F01-2000 resumes its normal functioning. The Interlock and ESD controls override the
fail-safe action according to Figure 47.
