To avoid injury to persons, damage to property or the environment, the following
warning notes should be observed!
Do not open, interfere with or modify the unit!
•
Before performing any wiring changes in the connection area of the LMO..., com-
pletely isolate the burner control from the mains supply (all-polar disconnection)
•
Ensure protection against electric shock hazard by providing adequate protection
for the burner control's terminals
•
Check wiring and all safety functions
•
Press the lock-out reset button only manually (applying a force of no more than
10 N), without using any tools or pointed objects
•
Fall or shock can adversely affect the safety functions. Such units may not be put
into operation, even if they do not exhibit any damage
•
Ensure the relevant national safety regulations are complied with
•
Installation and commissioning work must be carried out by qualified staff
•
Observe the permissible lengths of the detector cables (refer to «Technical data»)
•
Always run the ignition cables separately while observing the greatest possible
distances to the unit and to other cables
•
Install switches, fuses, earthing, etc., in compliance with local regulations
•
Ensure the maximum permissible amperages will not be exceeded (refer to «Tech-
nical data»)
•
Do not feed external mains voltage to the control outputs of the unit. When testing
the devices controlled by the burner control (fuel valves, etc.), the LMO... may
never be plugged in
•
Make certain the live wires are correctly connected
•
Commissioning and maintenance work must be carried out by qualified staff
•
When commissioning the plant, when doing maintenance work, or after longer off
periods, make the following safety checks:
a) Burner start-up with flame detector dark-
ened
b) Burner start-up with flame detector ex-
posed to extraneous light
c) Burner operation with simulated flame
failure; for that purpose, darken the flame
detector during operation and maintain
that status
