5 Instructions for Maintenance

5.1 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 to

chapter 5.2.6 Faults During Operation and chapter 5.3 Troubleshooting).

5.2 Commissioning

5.2.1 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%.
