Important Safety Notes 1 - 4
The LMV5 is a safety device. Under no circumstances should the unit be modified or opened.
Siemens Building Technologies, Inc. will not assume responsibility for damage resulting from
unauthorized modification of the unit.
After commissioning, and after each service visit, the flue gas values should be checked across
the firing range.
All activities (mounting, installation, service work. etc.) must be performed by qualified staff.
Before performing any work in the connection area of the LMV5, disconnect the unit from the
main supply (all-polar disconnection).
Protection against electrical shock hazard on the LMV5, and on all connected electrical
components must be ensured through good wiring and grounding practices.
Fall or shock can adversely affect the safety functions of an LMV5. Such units must not be put
into operation, even if they do not exhibit any apparent damage.
When the LMV5 is running in automatic mode, actuators are continuously monitored by the
LMV5.
During commissioning, when the ratio-control curves are being set, the actuator positions are
NOT continuously monitored by the LMV5.
The technician is solely responsible for verifying the correct position of each actuator during the
ratio-control curve commissioning.
The coupling that is used between the actuator and the driven valve / damper is safety related,
and must be of a robust and flexible design. Should this coupling fail during operation, the LMV5
will no longer have control of the burner's combustion bringing about a hazardous condition.
Condensation and the entry of water into the unit must be avoided.
