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 LME39... 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 (ionization)
– 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
LME39…
The LME39... 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: No repetition

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.
