Note
Display depending on the PME7, refer to User Documentation A7105.x.
Function
Standby, waiting for heat request
Power ON / test phase (e.g. detector test)
Safety valve ON, air pressure switch test / POC test (timeout / locking after 5 seconds),
actuator opens in low-fire position / CLOSE position
Fan motor ON and air pressure switch test / settling time
Actuator travels to the prepurge position
Prepurging
Actuator closes until ignition load / low-fire is reached, and
parameter 259.02: Actuator opens to a position > ignition load
Preignition
1st safety time / ignition transformer ON
Safety time (ignition transformer OFF), flame check
Interval: End of safety time and fuel valve V1 ON
Interval: End of safety time and load controller release
Interval: End of safety time and fuel valve V2 ON
2nd safety time
Parameter 259.01: Actuator opens to a position > low-fire
Parameter 260: Actuator closes until low-fire position is reached
Interval to release of preset load controller (analog or 3-position step input)
Operation, modulating operation
Operation first stage
Operation second stage
Actuator travels to the CLOSED position (home run)
Actuator opens until high-fire position / operation shutdown is reached
Postpurging
Test space evacuating
Test time atmospheric pressure
Test space filling
Test time gas pressure
Undervoltage / overvoltage
Safety shutdown, followed by a non-alterable lockout with interlocking
 e.g. safety loop open
Extraneous light on burner startup (timeout / locking after 30 seconds)
Pressure switch-min open
 safety shutdown / non-alterable lockout with interlocking
Lockout phase
