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 unit!
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 burner control’s connection terminals
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»
Press the lockout reset button only manually (apply a force of no more than 10 N),
without using any tools or pointed objects
Do not press the lockout reset button on the unit or the remote lockout reset button
(input 21)for more than 10 seconds since this damages the lockout relay in the unit
Fall or shock can adversely affect the safety functions. Such units must not be put
into operation, even if they do not exhibit any damage
For safety reasons – self-test of the flame supervision circuit, etc. – at least one
controlled shutdown must take place every 24 hours
In the case of flame supervision with UV detectors QRA2 / QRA4 / QRA10, it
should be noted that sources of radiation such as halogen lamps, welding
equipment, special lamps, ignition sparks, as well as X-rays and gamma radiation,
can produce erroneous flame signals
Mounting notes
Ensure that the relevant national safety regulations are complied with
Connect the earthing lug inside the terminal base to burner ground using a screw
with a lockwasher
An ignited UV tube is a source of UV radiation! In case of flame supervision by
means of flame detectors, the detectors must be placed such that there is no
direct visual contact between them. If this is not observed, there is a risk of loss
of safety functions
Installation notes
Always run the high-voltage ignition cables separately while observing the greatest
possible distance to the unit and to other cables
Do not mix up live and neutral conductors
Install switches, fuses and grounding in accordance with local regulations
Do not exceed the maximum permissible current rating of the connection terminals
The insulation of internal wiring which is subjected to the mains voltage must be
able to withstand the electrical loads occurring during proper use
