Warning notes 
To avoid injury to persons, damage to property or the environment, the following 
warning notes must be observed! 
 
Do not to open, interfere with or modify the unit! 
 
•  All activities (mounting, installation and service work, etc.) must be performed by 
qualified staff 
•  Before making any wiring changes in the connection area, completely isolate the 
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be 
inadvertently switched on again and that it is indeed dead. If not observed, there is 
a risk of electric shock hazard 
•  Ensure protection against electric shock hazard by providing adequate protection 
for the burner control’s connection terminals 
•  Check the connecting lines of the air pressure switch for short-circuits (connection 
terminals 3, 6 and 11) 
•  Press the lockout reset button / operation button of LME... or the AGK20… lockout 
reset button extension only manually (applying a force of no more than 10 N) with-
out using any tools or pointed objects 
•  Fall or shock can adversely affect the safety functions. Such units must not be put 
into operation, even if they do not exhibit any damage 
•  Each time work has been carried out (mounting, installation, service work, etc.), 
check to ensure that wiring is in an orderly state and make the safety checks as 
described in «Commissioning notes» 
Engineering notes 
•  When used in connection with actuators, there is no position feedback signal from 
the actuator to the burner control 
•  When used in connection with actuators, the requirements of applicable norms and 
regulations must be observed 
•  The running times of the actuators must match the burner control’s program. An 
additional safety check of the burner control together with the actuators is required 
•  When substituting burner controls type LGB… or LMG… by LME…, the AGQ1… or 
AGQ2… ancillary unit must be replaced by the AGQ3…A27 
Mounting notes 
•  Ensure that the relevant national safety regulations are complied with
