Valve proving takes place depending on the parameter:
Between phase 62 and phase 70 or / and between phase 24 and
phase 30
1 Parameter: Short / long preignition time for oil only
Short / long oil pump – switch-on time – time
2 Only with valve proving on startup
3 Parameter: With / without alarm in the event of prevention of
startup
4 In the event of an erroneous signal on startup, followed by
phase 10, otherwise phase 70
5 27 s = maximum time safety phase, followed by lockout
6 5 s = time between occurrence of prevention of startup and
indication
7 Only with valve proving on startup (valve proving via pressure
switch-min)
8 Only in case of startup without valve proving (valve proving
via pressure switch-min)
9 Inverse logic in case of valve proving via pressure switch-min
10 Parameter: Oil pressure min input
1 = active from phase 38
2 = active from safety time
11 Only with fuel train Lo with 2 fuel valves
Assignment of times:
t1 Prepurge time
TSA Safety time
Permissible position range
In standby: the actuator can travel within the permissible
positioning range, but is always driven to the no-load po-
sition. When changing phases, it must be in the no-load
position.
