Impact Resolution
Check the circuitry
and whether there is
a leak or check the
condition of the
evaporator,
probably blocked
with ice
Check probe alarms
and verify their state
and connections
Check probe alarms
and verify their state
and connections
Check probe alarms
and verify their state
and connections
Check probe alarms
and verify their state
and connections
Check probe alarms
and verify their state
and connections
Check whether the
pressure in the
circuit is consistent
with that measured
and if necessary,
modify tripping
threshold A65
Check whether the
pressure in the
circuit is consistent
with that measured
and if necessary,
modify tripping

with that measured
and if necessary,
modify tripping
