2.5.2 Electrical / electronic devices
Danger to life caused by electrical current!
Contact with live wires or components presents a danger
to life !
Before working on electrical components, disconnect the
compact flame controller from the mains power supply!
In keeping with the electrical regulations, work on electri-
cal / electronic parts / components may only be carried
out by electrical specialists.
Important rules of conduct
 Check the device in regular intervals. Any defects or
faults ascertained have to be corrected immediately.
Switch off the machine until the defects have been cor-
rected.
 If work is required on live parts, a second person has
to be assigned who can disconnect the power supply in
case of an emergency. Only use insulated tools !
2.5.3 Testing in keeping with the German Work-
place Safety Ordinance (BetrSichV)
In case of the coupling or installation of devices from vari-
ous manufacturers or suppliers, the operating company
has to carry out a precise test, prior to start-up, in keeping
with the German Workplace Safety Ordinance (BetrSichV)
in force and the applicable electrical regulations.
In case of queries, please get in touch with BFI Automa-
tion.
2.5.4 Safety test prior to initial operation
Danger of injury and material damage if improperly used!
Improper use of the compact flame controller can lead to
injury or even death and to material damage!
In order to ensure correct operation, the compact flame
controller must be tested several times for all applications
by starting and stopping the burner several times. In all
cases the flame relay must switch off reliably in case if the
flame is not detected. Carry out these tests whilst several
neighbouring burners are started and stopped and differ-
ent boiler outputs are used. This is an indispensable pre-
requisite for a safe and correct operation of the device!
