4.2.2 Power Failure Detection
The Power Failure detection (PFd) mode is used to determine the PowerPac power
supply’s response to power failures and is set as described in Section 3.1 . There are
three PFd modes:
ON : PFd is enabled and "PFd" appears on the run screen. A run will resume when
power is restored after single or multiple power failures(s).
ON NEXT RUN ONLY : PFd is enabled for a single run and is then disabled for all
subsequent runs. "PFd" appears on the run screen for the run in which it is active.
OFF : PFd is disabled. A run will terminate if a power failure occurs and Error code 07
appears on the screen (see Section 4.2.4
).
