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 quali-
fied staff
•
Before making any wiring changes in the connection area of the LME39..., 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 discon-
nected, 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 («LP» between
terminals 2 and 6)
•
Press the lockout reset button / operation button 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»
•
The data line for the AZL2... display and operating unit or other accessories, such as
the OCI410... (plugs into the BCI interface), must be connected or disconnected only
when the burner control is dead (all-polar disconnection), since the BCI interface does
not ensure safe separation from mains voltage
•
When used in connection with actuators, there is no position feedback signal from the
actuator to the burner control
•
The running times of the actuators must match the burner control's program. An addi-
tional safety check of the burner control together with the actuators is required
•
If the communication interface (jack RJ11) is not used, protection against electric
shock hazard must be provided (jack must be covered up)
Ensure that the relevant national safety regulations are complied with.
