Display and Operational Controls
Represented in chapter
6.1 Layout of the Operational Controls
.
5.1.1
Sensitivity Range - Indication
This display type only exists in the F200K2 execution type. The display shows the sensitivity
ranges I or II activated by external selection. The range I (normal sensitivity) is mainly used
for high flame intensities, whilst range II (higher sensitivity) is used for weaker flame intensi-
ties.
5.1.2
Operating State - Indication
The red LED shows the ’Flame OUT’ operating state. Whilst indicating 'Flame IN' the green
LED pulses in intensity to indicate the self-monitoring operation of the system. The pulse fre-
quency is the same as the self-monitoring cycle time (1.5 or 3.0 seconds). If the green LED
does not pulse then this could be symptomatic of electromagnetic interference (EMC) or a de-
fect of the compact flame scanner. (refer to chapters from
5.2.4 Fault on Flame Detection
chapter
).

General Information
5.2.1.1 'Flame Out' State
After switching on the power supply, the flame scanner is ready for operation after approxi-
mately 5 seconds. The following display has to be shown:
5.2.1.2 'Flame In' State
To check the monitoring parameters, install the compact flame scanner in the specified mount-
ing place before starting the operation of the furnace. If the flame burns naturally, the display
should change as follows:
- Display ’Flame out’
’Red’ LED lights up
- Sensitivity range I or II
’Yellow’ LED lights depending on external pre-selec-
tion f. range I or II (for F200K2 only)
’Red’ LED
Goes out
’Green’ LED
Lights up, changing its radiation intensity antivalently
to the cycle rhythm of the self-monitoring system.
Intensity indicator (lighting point) should reach 100%.
