ADJUSTING RPM OPERATING POINTS FOR MINIMUM LOAD (P1), IGNITION LOAD (P0) AND NOMINAL LOAD (P2) FOR THE
TECHNICIAN.
REQUIREMENTS
• The first PWM basic parameter setting was carried out in OEM level.
• Equipment wiring in conformity with application recommendation.
• Available mains voltage.
• Closed safety circuit.
• Heat request OFF, equipment in stand-by mode (OFF).
WITH LME7 INTERNAL CONTROL UNIT
CAUTION / WARNINGS
If no operation is carried out within 30 seconds, LME7 automatically switches to standard operation mode. The adjustment of the
operating points must be started again.

numbers are flashing.
• The equipment operates until the end of the pre-ventilation phase P30, goes to the ignition load position and switches to the display P0
(ignition load rpm). The display switches from P0 to a three-digit number.
CAUTION / WARNINGS
The three-digit number indicates the setting value for parameter P0/P1 or parameter P2 as rpm value, and must be multiplied by 10.
CAUTION / WARNINGS
The setting value for parameter P0 must be higher than the setting value for parameter P1.
Setting values are verified by LME7.
If setting rules are not observed, the equipment goes to lockout position, signalling a Loc:225 error
Start-up continues. The burner is switched on. The program continues in the minimum load position P1.
