Gas Burner Control Box
For 2-stage atmospheric gas burners
Possible flame detectors:
- Ionisation probe
- Infra-red flicker detector
INTRODUCTION
The TFI 812.2 gas burner control boxes are capable of
controlling and monitoring atmospheric gas burners. They
have been tested and approved as per DIN 4788 part 3
edition 04.89 and with the European standard EN 298. They
are also suitable for use with stationary warm air generators
(as per DIN 4794).
The control boxes are designed for maximum safety in case
of fluctuations in the voltage supply. If the mains voltage
drops below the permitted level, operation is interrupted
and the control box automatically prevents the start sequence
from being repeated. In this way, the safety of the system is
not put at risk by a drop in the mains voltage.
The control box and the monitoring function which it performs
is not negatively affected by occasional stray ignition sparks
jumping to the ionisation electrode.
The FR 870 remote reset (item no. 70700) can be connec-
ted, and allows remote reset of the control box (see doc.
no. 750).
The TFI 812 mod.5 can be installed in place of the TFI
712 F, and the TFI 812 mod.10 can be employed to replace
the TFI 712.
It is not necessary to rewire or replace the baseplate. The
difference in the heights of the units can be compensated by
attaching the reset button extension (item no. 70601).
The difference between the TFI 812.1 and the TFI 812.2 is
that the TFI 812.2 control boxes are equipped with the
voltage drop fail-safe function. Otherwise, they are identical
in terms of operation and possible applications.
CONSTRUCTIONAL FEATURES
The control box is well protected by a flame-resistant,
transparent, plug-in type plastic housing which encloses
the thermo-mechanical temperature-compensated timing
unit, the flame monitoring unit and the reset device.
The reset button, which incorporates an indicator lamp, and
the central screw fastening, are situated on the upper part
of the control box.
The baseplate, which can be equipped with additional
terminals, together with the various optional cable entry
points, makes universal wiring possible.
