·
Installation work must be carried out by qualified staff
·
Live and neutral conductors may not be mixed up
It is important to achieve practically disturbance-free signal transmission:
·
Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate low-capacitance cable
·
Observe the permissible cable lengths (refer to «Technical data»)
·
Always run high-voltage ignition cables separately, with the greatest possible dis-
tance to the unit and to other cables
·
Commissioning work must be carried out by qualified staff
·
When commissioning the plant or when doing maintenance work, make the follow-
ing safety checks:
a)
Burner startup with flame detector
darkened
b)
Burner startup with flame detector
exposed to extraneous light
c)
With wire strap «B»:
Simulation of loss of flame during
operation. For that purpose, darken
the flame detector during operation
and maintain this state
d)
Without wire strap «B»:
Simulation of loss of flame during
operation. For that purpose, darken
the flame detector during operation
and maintain this state
Conformity to EEC directives
- Electromagnetic compatibility EMC (immunity)
- Low-voltage directive
·
Maintenance work must be carried out by qualified staff
·
Each time a unit has been replaced, check to ensure that wiring is in an orderly
state and that the wires are firmly connected
The unit contains electrical and electronic components and may not be disposed of
together with household waste.
Local and currently valid legislation must be observed.
