impact shock, excessive moisture, or other problems rendering it inoperable. Repair work
must never be attempted and is strictly forbidden by the relevant European Standards.
WARNING!
Prior to commissioning the unit; carefully check that the wiring connections have been made
correctly. Also, before removing or checking the flame detector make sure the power supply
is switched off.
Mounting Instructions
The KLC 10/KLC 1000 should be mounted as close as practical to the flame and on the same
axis. The flame detector is compact and should be mounted with the KLC mounting flange or
other suitable holder having a 14mm Ø opening. Fix the detector in the holder taking care to
protect the sensor from other light sources.
To avoid any problems at start-up; please avoid alignment of the KLC detector with the ignition
spark electrode as the flame detector may react with the ignition spark and cause burner shut-
down during the air pre-purge/ignition start-up sequence. The maximum length of the connec-
tion cable must be in accordance with the technical data. Please ensure that the flame detec-
tor connection cable is kept well apart and is completely separated from high-energy igniter-
and power cables to avoid electrical interference problems.
CAUTION!
For safety reasons and within the technical regulations, a controlled burner shut-down
of the burner must occur and be guaranteed to happen at least once in every 24 hours
of operation.
Operating Indicator LED
The flame detector KLC 10/KLC 1000 indicates the following operating conditions and flame
signal strengths via the built-in LED.
Maintenance
The installation and commissioning must be done by qualified personnel only. Before energiz-
ing the KLC flame detector, check the cable and wiring connections if they are in accordance
to the diagram of the burner manufacturer. For good maintenance which will ensure trouble
free operation of the KLC flame detector; keep the sight glass clean by wiping with a soft dry
clean cloth. During commissioning and after any cleaning maintenance, the flame detector
LED is OFF KLC is not switched on – no power supply or ‘no flame’ is detected
LED is FLASH-
ING
KLC has detected a flame; the quality of the flame signal is indicated by
the intensity of the flashing of the LED – fast flashing indicates a healthy
flame signal and vice versa - slow flashing indicates a weak flame signal.
LED is ON KLC has detected the strongest level of flame signal.
Mounting Flange KLC
The mounting flange allows the detector to be
held and adjusted in a suitable position to
view the flame. An O-ring seal is available
which will give the mounting flange an air tight
seal to the burner housing if required.
Height = 7 mm.
