INTRODUCTION
The burner control boxes DVI980/982 controls and
supervises forced draught and atmospheric gasburners.
They are approved and certified according to the applicable
European standards and regulations. The use on direct air
heaters according DIN 4794 is also possible.
The microprocessor-based programming sequence ensures
extremely stable timings independent of voltage variations,
ambient temperature and/or switch-on cycles. The built-in
information system not only provides a continuous
monitoring of the actual state of the box (very helpful
especially for monitoring the start-up phase) but also informs
about the cause of a possible lock out. The lock out cause
is stored in such a way that it can be retrieved even after a
power failure. The control box is 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.
This low-voltage protection works not only during start-up
but also permanently during operation.
CONSTRUCTION FEATURES
Microprocessor, electronic components, output relais,
ignition spark generator and flame amplifier are placed on
the printed circuit board.
These plus the optional lockout- and reset circuit are well
protected inside a flame resistant plastic housing.
The LED for displaying the information system are placed
on top of the housing.
