Power Fail Recovery
In the event of power failure followed by power restoration, the instrument attempts to take
intelligent recovery actions to avoid a firing being aborted. The instrument has no direct
knowledge of how long the power has been off so the recovery action taken depends on where the
instrument had reached in the firing sequence prior to power failure as detailed below:-
Before Power Failure
After Power Failure
In
READY
mode
Timing delayed start
On Ramp 1 approaching t1
On Ramp 2 approaching t2
In Soak Period timing Soak
Time
Cooling after SOAK period
In
READY
mode
Immediate start as if the end of Delay Time reached
Immediate restart. Temperature will increase at ramp rate
1 of the current program starting at the present temperature
Immediate restart. If present temperature greater than t1
temperature will increase at ramp rate 2 of the current
programme starting at the present temperature. If present
temperature is less than t1 temperature will increase at
ramp rate 1 of the current program starting at the present
temperature
As above. The full soak period of the current program will
be re-applied
Cooling continued.
