L1
Errors that occur before ethylene oxide (EO) gas is in the
chamber and does not require immediate Service attention.
− Chamber too hot to start a
newcycle
− Timeout attempting to
reachtarget
− %RH setpoint
Operator can clear error and accessload.
Wait until Open Door or Open Load Door button isblue.
Press OpenDoor.
Press Clear to clear theerror.
Document per facilityprocedures.
Restart cycle per facility procedures.
L2
Errors that occur before EO gas is in the chamber and
require Service attention. Operator can open load door
before Service arrives.

EOInjection
− 12V/24V power supply failure
before EO Injection
Operator can accessload.
Wait until Open Door or Open Load Door button isblue.
Press OpenDoor.

− Service aborted cycle
CallService.
Service must access load and clear theerror.
Document per facilityprocedures.
Restart cycle per facility procedures.

under temperature failures after
EO Injection
CallService.
Service must access load and clear error. Document per
