1.1 Warning
notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
The LME7... are safety devices! Do not open, interfere with or modify the unit.
Siemens does not assume responsibility for damage resulting from unauthorized
interference!
Additional safety notes contained in other chapters of this document must be
observed as well!
All activities (mounting, installation and service work, etc.) must be performed by
qualified personnel
The burner or boiler manufacturer must ensure degree of protection IP40 for burner
controls as per DIN EN 60529 through proper installation of the LME7...
If not observed, there will be a risk of electric shock
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 (e. g. with dummy plugs for inputs and
outputs not used). If not observed, there is a risk of electric shock hazard
Ensure protection against electric shock at the LME7... and at all connected
electrical components through proper installation. In terms of execution, stability and
protection, covers must conform to EN 60730. If not observed, there will be a risk of
electric shock
The space where the program module is located is defined as plugging space and
therefore back-off-hand-proof when the program module is not fitted
Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring and parameterization is in an orderly state and make the
safety checks as described in
Commissioning notes
. If not observed, there is a risk
of impairment of safety functions and of electric shock hazard
If the housing or the area near the operating panel is damaged, the unit must
immediately be put out of operation. If not observed, there is a risk of electric shock
hazard
Press the buttons on the operating panel only manually without using any tools or
pointed objects. If the film of the operating panel is damaged, there is a risk of
electric shock hazard
The data line for the AZL2… or other accessories, such as the OCI410… (plugs into
the BCI), must be connected or disconnected only when the burner control is dead
(all-polar disconnection), since the BCI does not ensure safe separation from mains
voltage. If not observed, there is a risk of electric shock hazard
If the BCI (jack RJ11) is not used, protection against electric shock hazard must be
provided (jack must be covered up). If not observed, there is a risk of electric shock
hazard
Fall or shock can adversely affect the safety functions. Such burner controls must
not be put into operation, even if they do not exhibit any damage. If not observed,
there is a risk of impairment of safety functions and of electric shock hazard
To ensure protection against electric shock hazard, make certain that, prior to
switching on power, the signal cable AGV50... is correctly connected to the AZL2…
The mains-powered ionization probe is not protected against electric shock hazard.
Protection against accidental contact must be ensured. If not observed, there is a
risk of electric shock hazard
On the OEM level of the LME7…, it is possible to make parameter settings that
differ from application standards. When setting the parameters, it must be made
