Appendix A
A-5
Main Power Failure
When power is restored, the DPRSOO will continue with the function it had
before the failure, using the output signal determined by the setting of
FCODE 20. With 3-state pulse output, the actuator feedback must be
present for this to operate.
If the controller was in the Programming mode, performing Autotuning or
displaying setpoint in the digital display, these functions will not be
resumed automatically after a power failure. If required, they must be
selected again.
All parameters and functions which were selected during configuration will
remain stored in memory.
On restart, the software version number will be displayed for about 3
seconds in the digital display.
