Important Safety Notes
WARNING
Fire, Explosion or Electrical Shock Hazard. Can cause severe injury,
death or property damage.
Please fully read and understand the following notes before commencing with any work
related to the Mini Mk8 MM Flame Safeguard Controller. Failure to do so can result in
serious or even fatal injury, and can cause permanent equipment failure and substantial
property damage.
Installation, commissioning, burner start-up and changing Options/Parameters must only
be carried out by an Autoflame-trained and certified technician with thorough
understanding of the Autoflame combustion control systems and boiler/combustion
control in general. Any person carrying out this work without undergoing the necessary
training and gaining understanding of the boiler plant may place themselves and others
in a potentially dangerous situation or cause permanent equipment failure.
Any person working on a boiler plant must be adequately trained and have a thorough
understanding and appreciation of the boiler plant.
It is the responsibility of the commissioning technician to ensure that the system
operation meets all local codes and regulations.
Electrical connections are live; make sure to isolate the mains power, fully and safely,
before carrying out any work related to the wiring connections; failure to do so can result
in serious or even fatal injury.
Use extreme care while testing the system. Live voltages are present on most terminal
connections when the power is on and are a serious electrical shock hazard.
Replace all limits and interlocks not operating properly. Do not bypass limits and
interlocks.
Modification to the Autoflame system settings should only ever be carried out by a
qualified combustion engineer. Changes to the Autoflame control system setup has the
potential to make the controller operate in an unstable and potentially unsafe manner.

1.5. Relay Box
The relay box (SP80065) provides all the connections shown in section 1.3.1 for wiring between a servo motor
with high and low limit switches and the Flame Safeguard controller. It also provides for the switchover of
control to a load sensor allowing the burner to modulate once the flame has been established. The Flame
Safeguard unit will continue to monitor the status of the flame and initiate a safety shutdown in the event of
any issues.
For an On/Off burner, connections are defined in section 1.3.2 for an On-delay timer relay to allow the start-
up sequence to be carried out.
CAUTION - Equipment Damage Hazard.
Improper connection or replacement of relays or the relay box will cause equipment
failure.
