Technical description of the burner

Legend 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 sequential phase = 10
Direct startup sequential phase = 79
(when R = ON)
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 01
Continuous purging: Checking for on in 10 and
12, Stop up to phase-max time 01
14) Parameter: “OilPressureMin”, “akt_from_ts“ no check
before TSA1 (LO, HO) or TSA2 (LOgp, HOgp)
15) Parameter: “GasPressureMin“, “deakt_xOGP“ pres-
sure switch-min can be deactivated for oil pro-
grams with gas pilot
16) Parameter: “OilPumpCoupling“, “direct_coupl“ shutoff
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_Reli_Inv“ Output pressure switch
valve will be logically inverted
18) Parameter: “Alarm act / deact“, “deactivated“ The alarm
output can temporarily be deactivated (for cur-
rent error only)
19) Parameter: Only with LMV51...: Continuous pilot gas / oil:
Activated Pilot valve is also activated in op-
eration
20) Parameter: Only with LMV51...: Extraneous light, pilot
phase, operating phase gas / oil Separate
flame supervision possible
21) Parameter: Only with LMV51...: pressure switch valve prov-
ing / CPI or StartReleaseGas Parameter-
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 LMV51... software version 04.50 and
AZL5... software version 04.40, dependent on
parameter StartPktOperation
0° Position as supplied (0°)
90° Actuator fully open (90°)
AGR Fuel gas recirculation
CPI Closed position indication
DP Pressure tester
PS-VP Pressure switch – valve proving
FCC Fan contactor contact
LF Air damper
APS Air pressure switch
N Postpurging
SR Safety relay
SLT Safety limit thermostat
TL Temperature limiter
Repetition counter:
k) Heavy oil
l) Restricted startup behavior
n) Restricted safety loop
Permissible positioning range
In Standby: actuator can travel within the permissible po-
sitioning range, but is always driven to the home position.
Must be in the home position before changing the phase.
