Lifetime
The LMV6 has a designed lifetime* of 250,000 burner startup cycles which, under
normal operating conditions in heating mode, corresponds to approx. 10 years of
service (starting from the date of manufacture on the nameplate). This is based on the
endurance tests specified in the EN 298 standard. A summary of the conditions has
been published by the European Control Manufacturers Association (Afecor)
(www.afecor.org).
The designed lifetime is based on use of the LMV6 according to the manufacturer’s
data sheet and the basic documentation. After reaching the designed lifetime in terms
of the number of burner startup cycles, or after the corresponding usage time, the
LMV6 must be replaced by authorized personnel.
* The designed lifetime is not the warranty time specified in the Terms of Delivery.
System overview
The system components for the LMV6 (e.g., AZL66) are connected directly to the LMV6
via the CAN bus. All safety-related digital inputs and outputs of the LMV6 are monitored
via a contact-feedback network. The LMV6 is operated and parameterized via the
AZL66. The AZL66 features menu-driven operation, offering straightforward operation
and targeted diagnostics. When performing diagnostics, the display shows the
operating statuses and type of error are communicated via the display as well as via
the signal lamp (LED). The various parameterization levels of the burner/boiler
manufacturer and heating engineer are password-protected against unauthorized
access. Simple settings that the plant operator can make on site do not require a
password.
