Warning notes

To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
LMV36... basic unit and AGM60... switch unit are safety devices! Do not open,
interfere with or modify the units. Siemens does not assume responsibility for
damage resulting from unauthorized interference!
Inside of this documentation are warning notes which also be must observed!
After commissioning and after each service visit, check the flue gas values
across the entire load range!
The present Basic Documentation describes a wide choice of applications and functions
and shall serve as a guideline. The correct functioning of the units must be checked and
proven by function checks on a test rig or on the plant itself!

All activities (mounting, installation and service work, etc.) must be performed by
qualified personnel

Degree of protection IP40 as per DIN EN 60529 for the basic unit must be ensured
through adequate mounting of the LMV36... basic unit and the AGM60... switch unit
by the burner or boiler manufacturer

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 and that it is indeed dead. If not disconnected, there is a
risk of electric shock hazard

Protection against electric shock hazard on the LMV36..., the AGM60... and on all
connected electrical components must be ensured through adequate mounting. In
terms of design, stability and protection, the cover used must conform to EN 60730

After each activity (mounting, installation and service work, etc.), check to ensure
that wiring is in an orderly state and that the parameters are correctly set

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

When programming the air-fuel ratio control curves, the commissioning engineer
must constantly watch the quality of the combustion process (e.g. by means of a
flue gas analyzer) and, in the event of poor combustion values or dangerous
conditions, take appropriate actions, e.g. by shutting down the system manually

When starting up a dual-fuel burner, both fuel trains must be put into full
operation, thus making certain that fuel changeover by the user cannot lead to
critical conditions

The inputs and outputs of the AGM60... may only be used for the application
covered by this document and only in connection with the sensors and
actuators specified for the application, the reason being that only these have
been checked and released in terms of error effects. If you want to use the
sensors and actuators on other applications, please contact Siemens

The following plug-on terminations carry FELV (functional extra low-voltage) (also
refer to chapter Electrical connection of LMV36... and AGM60...), thus ensuring
adequate separation from mains voltage:
- BCI (X56) for the connecting cable of AZL2... or PC software ACS410
- COM (X92) for accessories, such as the OCI410...
- Plug-on terminations for actuators (X54) or for the AGV61.100 connecting cable
when using 2 fuel actuators via AGM60...
These plug-on terminations may be disconnected or exchanged only when the plant
is dead (all-polar disconnection)
