Key to the sequence diagrams:
1)
Parameter: With / without pressure switch
2)
Parameter: Short / long preignition time for oil only Short /
long oil pump – ON – time
3)
Delayed shutdown within TSA1 + TSA2
4)
Parameter: Output as startup signal / pressure switch relief
valve
5)
Parameter: Normal / direct startup
Normal startup
Direct startup
6)
Sequential phase = 24
7)
Only with valve proving during startup
8)
Parameter: With / without alarm on prevention of startup
9)
Parameter: With continuous purging the shown output sig-
nals are inverted
10) Fan controlled as before
Running time when LOCK OUT = T_FanLockout LF
11) Parameter: With / without extraneous light test in STANDBY
12) With valve proving during startup phase 10
13) Parameter: Normal / continuous purging
Normal purging: Checking for off in 10, stop to
Ph-max time
Continuous purging: Checking for on in 10 and
12, Stop up to phase-max time
14) Parameter: "OilPressureMin", "akt_from_ts"
before TSA1 (LO, HO) or TSA2 (LOgp, HOgp)
15) Parameter: "GasPressureMin",
sure switch-min can be deactivated for oil pro-
grams with gas pilot
16) Parameter: "OilPumpCoupling", "direct_coupl"
valve oil has to be connected to output "Oil pump
/ magnetic clutch".
Output is active when fan is on and for another
15 s after fan is switched off
17) Parameter: "Start / pressure switch valve", "PS_Re-
li_Inv"
logically inverted
18) Parameter: "Alarm act / deact", "deactivated"
output can temporarily be deactivated (for cur-
rent error only)
19) Parameter: Only with LMV52...: Continuous pilot gas / oil:
Activated
eration
20) Parameter: Only with LMV52...: Extraneous light, pilot
phase, operating phase gas / oil
flame supervision possible
21) Parameter: Only with LMV52...: pressure switch valve prov-
ing / CPI or StartReleaseGas
dependent ON / OFF test
CPI Gas: OFF test for gas trains only
CPI Oil: OFF test for oil trains only
CPI Gas+Oil: OFF test for gas and oil trains
22) Parameter: After LMV52... software version 04.50 and
AZL5... software version 04.40, dependent on
parameter StartPktOperation
