Infrastructure & Citiies Sector 7 Basic unit 25.09.2013
Indices
1) Parameter: Short/long prepurge time for oil only
Short/long on time of oil pump – time
2) Only with valve proving during startup
3) Parameter: With/without alarm in the event of start prevention
4) If signal is faulty in the startup phase, phase 10 is next, otherwise phase 70
5) Max. time safety phase, then lockout
6) Time from occurrence of start prevention to signaling
7) Only in case of valve proving during 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 276: Oil pressure min-input
1 = active from phase 38
2 = active from safety time
11) Only with fuel train Lo and 2 fuel valves
12) Parameter 223: Repetition limit value gas pressure switch-min in connection
with gas shortage program parameter 246 (phase 90)
13) Max. drop-in/response time for air pressure switch
14) Alternative to valve proving
15) Alternative to pressure switch-max (Pmax) or POC
