PFD: The Power Failure Detection feature will save the time, voltage and current settings in
the event of a power outage and automatically continue the run when the power is restored.
To alert the user that a power failure occurred during the run, the error message “E6” flashes
at the end of the run instead of the usual “OFF” message. The “E6” error message means
that despite the power outage, the power supply successfully supplied the programmed
voltage and current for the entire length of time that was programmed. The time shown at
the end of the run is the time the gel ran since power was restored, not the total time of the
run. The default settings for Power Failure Detection are:

The Power Failure Detection feature can be deactivated during a timed run.
Press the MODE button to move the indicator light under clock symbol.
Press the UP and DOWN buttons to enter in the run time in minutes.
Press both the UP and DOWN buttons at the same time. The display will briefly
show “PF0”, indicating that the PFD mode is disabled.
Press both the UP and DOWN buttons at the same time again. The display will
show “PF1”, indicating that the PFD mode is enabled.
8. Start the run: Press the RUN button. The green LED light above the RUN button indicates
that voltage and current are being applied to the output jacks. The green LED light above the
CONST button indicates which parameter (V or A) is limiting. The LED display shows the
numerical value of the actual V or A output, or the time (Press the MODE button to toggle
between the values). The timer will count up in the case of a continuous run and count down
if the timer was set for a specific timed duration.
9. Stop the run: A timed run will automatically stop with a warning beep as described above.
In the case of a continuous run, press RUN button to terminate the run (The green LED light
above the RUN button will turn off indicating that the voltage and current which was being
applied to the output jacks were stopped.). The display reads “OFF”. To reset the power
supply press any button except the RUN button.
