Electrical wiring of the infrared flame detection probe.
It is important to achieve practically disturbance- and loss-free
signal transmission:
•
Never run the detector cables together with other cables:
– Line capacitance reduces the magnitude of the flame signal.
– Use a separate cable.

•
Observe the permissible cable lengths.
•
The detection probe is not protected against electrocution
risks and must be protected against accidental contact.
•
Place the detection probe so that it is correctly installed and
the flame is correctly detected.
