Installation notes
 Always run the high-voltage ignition cable separate from the
unit and other cables while observing the greatest possible
distance.
 Do not mix up live and neutral conductors.
 Install switches, fuses and earthing in compliance with local
regulations.
 The connection diagrams show the burner controls with
earthed neutral conductor.
 Make certain that the maximum permissible current rating of
the connection terminals is not exceeded.
 Make certain that strain relief of the connected cables is in
compliance with the relevant standards.
 Do not feed external mains voltage to the control outputs of
the unit. When testing the devices controlled by the burner
control (fuel valves, etc.), the LME71... must not be connected
to the units.
 The mechanical coupling between the actuators and the con-
trolling elements for fuel and air, or any other controlling ele-
ments, must be rigid.
 Check the connecting lines of the air pressure switch for short-
circuits.
Electrical connection of flame detectors
It is important to achieve practically disturbance- and loss-free sig-
nal transmission:
 Never run the detector cable together with other cables:
– line capacitance reduces the magnitude of the flame signal;
– use a separate cable.
 Observe the permissible detector cable lengths (see Technical
Data).
 The mains-powered ionization probe is not protected against
electric shock hazard.
 Locate the ignition electrode and the ionization probe such
that the ignition spark cannot arc over to the ionization probe
(risk of electrical overloads) and that it cannot adversely affect
the supervision of ionization.
