Honeywell IRD 1020.1 Manual

Infra-red flicker detector IRD 1020.1
Flame detection device for
oil and gas flames
INTRODUCTION
The IRD 1020.1 detector is used to supervise gas or oil
flames. This flame monitoring device should be connected
to a Satronic oil burner control box. Monitoring is based on
the infra-red flicker principle, in other words, the flickering
infra-red light of the flame is detected. The steady radiation
from, for example, the glowing refractory layer on the inside
of the boiler, has no effect on the detector. The IRD 1020.1
replaces the IRD 1020 and 920.
When exchanging the IRD 1020, care must be taken that the
corresponding IRD 1020.1 with the same imprint (blue or
white) is used (see page 3 and 4).
When exchanging the IRD 920, care must be taken to wire
the sensor correctly (see page 3), and the existing holder
must be exchanged with the magnetic holder M93.
For replacement of the IRD 920 with IRD 1020.1 is the
sensor cable also needed.
The infra-red flicker detector can be used with any one of the
following control boxes:

CONSTRUCTIONAL FEATURES
The infra-red sensor and the pre-amplifier are hermetically
sealed in glass and along with the electronics form an
integrated unit in the flame detector. Wiring is by way of a
plug connection. The sensitivity control and two LED's for
indication of the flame signal are situated on the rear of the
flicker detector.
