Description
• 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 the LME… or the AGK20… lockout reset button extension only manually (applying a force of no more than 10 N) without 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
