pensing is not allowed when Out of

cally starts when this Error is displayed.
Prevent dispensing and give the test time to
finish { from 13 minutes to 4 hours later }.
This may happen in extremely busy stations.
Are the turbines turned-off after hours ?
Ask the station to keep the circuit breakers /
turbines on so tests can finish after hours.
Call INCON if the Leak Test does not finish.

which would cause indeterminate test result
(neither pass or fail), and will cause the days
to count up. )
