INTRODUCTION
The DKO 970/972 oil burner safety control boxes are suitable
for oil burners with throughputs up to 30 kg/h. They are
approved and certified according to the applicable European
standards and regulations.
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.

TYPES AVAILABLE
DKO 970 1-stage operation
DKO 972 2-stage operation


CONSTRUCTIONAL FEATURES
The control box circuitry is protected by a flame resistant,
transparent plug-in type plastic housing. A central fixing
screw locks the control box to the wiring base.
The plug-in control box incorporates the microprocessor
based timer, flame check and reset circuits.
Manual reset from lock out and set to lock out is provided by
a push button with an integrated LED information system.
The wiring base S98 is equipped with spare- and
extraterminals and allows together with a variety of cable
entry points utmost flexibility of electrical wiring.
The DKO 970 is compatible with the TF 801, TF 801.2,
TF 830, TF 830.2. The DKO 972 is in addition compatible
with the TF 802, TF 802.2, TF 832, TF 832.2.
