8-2 Troubleshooting
If There Is a Power Failure
Introduction
An automated restart function allows for power failures and safe continuation of a PCR
run after resumption of power.
During a Power
Failure
The following table lists the actions the instrument takes if the power is interrupted and
the instrument turns off while you are operating it.
Note If the power is off for 15 seconds or longer and fails during execution of a cycle then the
cycle currently running will restart. If the power fails while executing a hold, or approaching a
hold, then that hold temperature will restart from the beginning.
Note If the power failure lasts longer than 18 hours, the Resume will not occur.
Do the following in a power failure:
Step Action
1 Restart or continue the PCR experiment.
The instrument determines what temperature was being approached, or was
holding.
Upon resumption of power, it will go to that temperature and countdown the time
remaining in the hold as soon as the temperature is within the specified clock start
limits.
2 Incubate the samples until you can continue the experiment.
3 Enter a record for any power outage in the history file.
