Basic unit

∂
The housing is made of impact-proof, heat-resistant and flame-retarding plastic. It
is of plug-in design and engages audibly in the base
∂
Burner controls LMO39... and plug-in base AGK11.6 are silver-grey (RAL7001)
∂
The housing accommodates the
– microcontroller for the program control and the control relays for load control
electronic flame signal amplifier
–
– lockout reset button with its integrated 3-color signal lamp for operational status
and fault status messages and the socket for connecting the interface OCI400...
adapter or the AGK20... lockout reset button extension
∂
All safety-related digital inputs and outputs of the system are monitored by means
of a contact feedback network
∂
The display and operating unit AZL2... is designed for direct connection to the
LMO39...
∂
The LMO39... is operated and parameterized via the AZL2... or with the help of the
OCI410 / ACS410
∂ Burner capacity unlimited (thermal output on startup '120 kW)
∂
3 repetitions in the event of loss of flame during operation (can be parameterized)
 Default setting: Non-alterable lockout

The diagram shows the full scope of functions of the LMO39... system. The actual
functions are to be determined based on the respective execution/configuration.

3.1 Time parameters

Parameterized times see Type summary.
Both the prepurge time and the safety times are safety-related and can be changed by
the OEM with the help of the display and operating unit AZL2... or PC software
ACS410.
