Phase 6
The bridge between 2-8 must be connected to 2-4.
Phase 7
The wiring from servomotor to (9) must be connected to (1). (high low burners).
Every wiring to pin number 11 must be eliminate.
If in the application the control box used output 11 must be connected into the clamp number 14.
IMPORTANT: must be verified the correct functionality of the application during changing from 2th to
3th stage operation.
WARNING:
For the replacement of the RMG 508 and 509 SE control boxes with the RMG8862A2 control box on the
R.40 GS 20P and R.40 GS 10P burners, follow the procedure below
ONLY FOR THE R.40 GS 20P:

RESETTING THE CONTROL BOX AND USING DIAGNOSTICS
The control box features a diagnostics function through which any causes of malfunctioning are easily iden-
tified (indicator: RED LED).
To use this function, you must wait at least 10 seconds once it has entered the safety condition (lock-out),
and then press the reset button.
The control box generates a sequence of pulses (1 second apart), which is repeated at constant 3-second intervals.
Once you have seen how many times the light pulses and identified the possible cause, the system must
be reset by holding the button down for between 1 and 3 seconds.
RED LED on
wait at least 10s
The methods that can be used to reset the control box and use diagnostics are given below.
