Flame sensor FFS 06

Installation and operation of the flame sensor
Install the flame sensor (Fig. 9) with its assembly bracket to the
opening of the burner, so that the flame of the burner can be mon-
itored and visible during the burner ignition phase.
The min. threshold value for IR flame sensors is 15 mV and 25
mV for UV flame sensors. More information on installation are in-
cluded in the technical documentation of the flame monitoring de-
vices.
The sensitivity of the UV flame sensors cannot be
adjusted.
To obtain the optimum angle of incidence for
WARNING
flame monitoring, the signal voltage must be
measured at its maximum.
The flame sensor must be connected according to the colour cod-
ing of the monitoring device used, respectively from the allocation
of the ETAMATIC terminals (Fig. 10).
The connection cable has an additional measurement wire (pink)
that can be used to measure the signal voltage via a handheld
digital multimeter (according to EN 61010, input impedance >5
M).
The voltage is measured between the ground potential (blue
wire) and the additional measurement wire (pink wire) of the con-
nection cable to determine an optimum flame detection.
