1.6 Electrical connection of flame detectors
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 detector cable lengths
 The mains-powered ionization probe is not protected against electric shock hazard.
It must be protected against accidental contact
 Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not suffice
 Locate the ignition electrode and the ionization probe such that the ignition spark
cannot arc over to the ionization probe (risk of electrical overloads)
 Insulation resistance
- Must be a minimum of 50 M between ionization probe and ground
- Soiled detector holders reduce the insulation resistance, thus supporting
creepage currents
