To avoid personal injury, damage to property or the environment, the following
warning notes should be observed!
•
It is not permitted to open, interfere with or modify the unit!
•
Before performing any wiring changes in the connection area of the LMG2..., the
burner control must be completely isolated from the mains supply!
•
Check wiring and all safety functions!
⇒
Risk of explosion
•
Press lockout reset button / operating button only manually (applying a force of no
more than 10 N), without using any tools or pointed objects!
•
Check the connecting wires of the air pressure monitor for short-circuits (terminals 3,
6 and 11)!
•
Check the electromagnetic compatibility with adjacent components!
•
On applications with actuators, the actuator does not feed a position checkback signal
to the burner control.
The actuator running times must be matched to the burner control's program. An
additional safety check of the burner with the actuator must be made!
•
The relevant national safety regulations must be complied with!
•
Locate the ignition and detector electrode such that
–
the ignition spark cannot arc over to the detector electrode!
⇒
Risk of electric overloads
–
the ignition spark cannot adversely affect ionization supervision!
•
Installation and commissioning work may only be carried out by qualified staff!
•
Observe the permissible length of the detector cables!
⇒
Refer to «Technical data»
•
Always run ignition cables separate from the unit and other cables while observing the
greatest possible distances!
•
Before putting the burner control into operation, check wiring carefully!
•
Install switches, fuses, earthing, etc., in compliance with local regulations!
•
The connection diagrams shown apply to burner controls with earthed neutral. In the
case of ionization current supervision in networks with non-earthed neutral, terminal
2 must be connected to the earth conductor via an RC unit
(part no. ARC 4 668 9066 0)!
•
Do not exceed the maximum permissible switching capacity of the connection
terminals!
•
No mains voltage may feed back to the control´s output terminals from an external
supply or source.
When checking the functioning of devices controlled by the burner control (gas
valves, etc.), the burner control may never be plugged in!
•
In the case of burners with no fan motor, an AGK25 must be connected to terminal 3
of the burner control, or else the burner cannot reliably be started up!
•
For safety reasons, feed the neutral conductor to the neutral distributor on the plug-in
base, or to terminal 2, and from there to the various devices (fan, ignition transformer
and gas valves) or to an external neutral distributor!
