•
When pressure is greater than or equal to 0.75
IWC and Canister load is less than 80%.
•
Pressure is greater than or equal to 1.3 IWC and
Canister load is greater than 80%.
CLOSE
PURGE TIME
The canister state is in excess purge and the
time is outside 6AM to 4PM.
CLOSE CVLD
TEST
Valve was closed to collect data for ISD contamina
-
tion leak test.
CLOSE
FORCE
PURGE
Canister is in startup period. Loading with
pressures <+1.05 is not allowed until startup
period is complete.
CLOSE LIMIT

extended capacity loading limit.
CANISTER
EMPTY
