Fig. 2.4 Motor Starter and Thermal Overload
Electric Ignition OFF
Five seconds later the electric ignition turns off, leaving the start gas flame to be proved as stable.
Main Gas Valve Energises
Following a short delay the main gas valves energise and the main flame cross lights from the start
gas. The control is now in its normal run position.
Close Down
When the external controls are satisfied the control box turns off all outputs simultaneously and
returns to rest position for the beginning of the next sequence.

Fault Conditions
If at any stage the flame fails the control will go to ‘lockout'. The red light will glow and the control will
need to be manually reset before any further start attempt can be made.
Minimum flame probe current 1 µA DC.
Typical flame probe current 3-5 µA DC (on main flame)
