Interruption of flame OK or Alarm Signal between flame
controller - control module HL1.
Check connection between FA and CM / GM:

CM: for OGS 6.10 to OGS 12.20: X14:1/2 and X15:12
(for units without GM)

GM: Plug X20:5/6 and X25:10

FA: Clamps 1, 2, 5

Interruption of Flame OK or Alarm signal between flame
controller - SG control.
Check connection between FA and GM:

GM: Plug X21:4/5 and X25:11

FA: Clamps 1, 2, 5

Interruption of Flame OK or Alarm signal between flame
controller - control module HL2.
Check connection between FA and GM:

GM: Plug X22:4/5 and X25:12

FA:Clamps 1, 2, 5

Hot air contactors do not switch off (burnt together)

Motor not operating (e.g. because of 2 defective
miniature fuses F10, not with the 6.06 as F10 protects
the CM).

CTC probe has temperature higher than the maximum
acceptable value (sensor not correctly inserted into the food
