False light at start
If oil is released and no flame is established the con-
trol will cut out within the safety time of: 10 seconds.
Flame failure in operation
In the event of flame failure in operation the oil sup-
ply is cut off and the control restarts the burner as
described under the heading “Normal Start”. On
flame failure, immediately after burner start, the con-
trol will initiate re-ignition.
Flame monitoring
The flame is monitored by a photocell unit. Note: In
accordance with the latest ISO and DIN standards,
type LOA activates the safety relay if the photocell
unit is exposed to light in the pre-purging period.
Control of flame signal
The photocell current is measured with a d.c.
ammeter (moving coil instrument) which is connect-
ed in series with the photocell unit. Min current for
flame indication: 35 µA.
