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
Ensure that the relevant national safety regulations are complied with.
When converting plant to LOK16... or LGK16..., the existing LAL... or LFL... base must
be secured by a cylinder-shaped grooved pin, thus ensuring that only an LOK16... or
LGK16... type burner control can be fitted.
Part number of grooved pin: 4 166 8024 0
Location of grooved pin:
Between terminals 10 and 11 of the LAL... base, and between terminals 4 and 5 of the
LFL... base.
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.
Always run the high-voltage ignition cables separately while observing the greatest
possible distance to the unit and to other cables
Neutral conductors must not be interchanged
Install switches, fuses, earthing, etc., in compliance with local regulations
Make certain that the maximum permissible current rating of the connection
terminals will not be exceeded
