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 (applying 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 reset button
(input 21) for more than 10 seconds, since this would damage the lockout
relay inside 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
 In the case of flame supervision with flame detectors QRA53 / QRA55, 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!
If the flame is monitored by several flame detectors, all detectors must be placed in
a way that ensures there is no direct visual contact between them.
If this is not observed, there is a risk of loss of safety functions
When equipping existing plants with LOK16 or LGK16, the existing plug-in base for LAL
or LFL burner controls must be replaced with the matching plug-in base AGM17 for
LOK16 / LGK16.
By removing link (B) on the underside of the unit, the LOK16... can be switched to start
repetition in the event of loss of flame during operation.
In that case, the wire link must be cut off completely.
However, it must be checked whether this is in compliance with national standards and
regulations.

Note!
In applications involving air heaters (WLE), or in the case of oil burners with a
maximum throughput of > 30 kW/h, removing wire link B is not permitted.
