- at N2 > 50 percent the starter shutoff valve closes and ignition system 1(2) is no more excited
3 Place the ENG/MODE/CRANK/NORM/IGN/START selector switch in
_
NORM position :
- the ENG page disappears
4 Place ENG/MAN START pushbutton switch in OFF position

E E With the MASTER control switch in ON position or ENG/MAN START pushbutton switch set to ON and the ENG/MODE/CRANK/NORM/IGN/START selector switch in NORM position : there is not effect on the corresponding engine (if it is not running).
(3) Alternative start interruption
You interrupt the alternative start if :
- you release ENG/MAN START pushbutton switch with the MASTER control switch in OFF position
- you place the MASTER control switch back in OFF position if it was to ON.
C. Continuous Ignition
(1) Manual selection When engines are running on ground or in flight : place the ENG/MODE/CRANK/NORM/IGN/START selector switch in IGN/START position.
(2) Automatic selection
For an in-flight restarting when :
- you select engine anti-ice (ECS data).
- the EIU fails (except during cranking).
- flameout is detected
- ignition delay during start During an automatic start, as soon as N2 is higher than 16 percent, the start must occur in the 15 to 20 seconds that follow (depending on the ambient temperature). If this time is greater and the ECU does not detect a difference of the EGT of at least 42 DEG.C, the ECU controls a dry motoring cycle followed by a selection of the continuous ignition.
D. Failure Indicating
An ECAM message is displayed:
- in case of no light off detection (amber caution)
or
- in case of ignition system failure or power supply not available.
