Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not open, interfere with or modify the flame detector!
 All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
 Before making any wiring changes in the connection area, completely isolate the
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. If not observed, there is
a risk of electric shock hazard
 Ensure protection against electric shock hazard by providing adequate protection
for the connection terminals. If this is not observed, there is a risk of electric shock
 Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state and make the safety checks as
described in «Commissioning notes». If this is not observed, there is a risk of loss
of safety functions and a risk of electric shock
 Fall, shock or damage to the housing can adversely affect the safety functions.
Such detectors must not be put into operation even if they do not exhibit any
damage. If this is not observed, there is a risk of loss of safety functions and a risk
of electric shock
Mounting notes
 Ensure that the relevant national safety regulations are complied with
 Tightening torque clamp: Maximum 0.3 Nm
Installation notes
 Always run the detector cable separate from other cables, especially from the high-
voltage ignition cable, while observing the greatest possible distance
It is important to achieve practically disturbance- and loss-free signal 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 length of the detector cables (refer to «Technical data»)
Commissioning notes
 The intensity of the radiation of light on site is checked by measuring the detector
current
 For information about the measuring circuit and the minimum detector current
values required, refer to the Data Sheet of the relevant type of burner control
