Satronic MMI 813.1 Manual

Gas burner automatic
Safety control
For 2-stage forced draught gas burners
Designated for an air damper control
Possible flame detectors:
- Ionization probe
- Infrared flicker detector

INTRODUCTION

The gas burner automatic safety control MMI 813.1 controls
and monitors blown gas- and combined burners of any
nominal thermal load (tested and certified according to
EN 298).
Together with an air damper motor, a 2-stage burner with
2 fuel valves, a 2-stage operation with 1 fuel valve or a
modulating system ave possible.

CONSTRUCTIONAL FEATURES

The automatic control is housed in a non-inflammable,
transparent, plug-in type plastic case and contains:
– Synchronous motor with speed reducer gears as the
drive for the switching cam
– Switching cam with informative programme display in
colour
– 12 times cam drive for controlling the programme
sequence
– Plug-in type circuit boards with the electronic components
The following important indicating - and operating elements
are located on the front panel of the automatic control:
– Illuminated pushbutton for indication of malfunctions
and reset
– Programme display in colour
– Screw for central mounting
