Times:
-purge time (TW):
TW for type SM152N
time at start-up (TS):

response time in case of flame failure
The times appearing on the product label correspond to guaranteed
values. Actual times may differ from declares ones, as waiting and
pre-purge time may be longer and safety time shorter than their

nominal values.
Power consumption at start-up:
atmospheric burner
atmospheric fan-assisted burner
Power consumption during operation: atmospheric

Flame monitoring:
The flame detection device exploits the rectification property of the
flame (ionization); the device is not provided with any protection
impedance and is therefore not safe against the risk of electric
shock.

(1): The auxiliary contact is not type SELV (Safety Extra Low Voltage) and is therefore
not suitable to control SELV circuits.

Upon request it is possible to meet particular requirements
regarding times, spark repetition rate, min ionization current and
operating cycle.
CONSTRUCTION
The plastic casing protects the control unit from any damage
resulting from impacts, tampering, dust and contact with the
external environment.
A particular construction technique, consisting of four PCBs
assembled together to form a "box" structure, has enabled
considerably reduce the dimensions of the device.
A varistor protects the control unit from any voltage transients
which may arise in the mains supply.
An inbuilt fuse protects the internal relays of the unit in case of short
circuit on the control outputs (valves, fan and lockout signal). As
this fuse is not accessible, the unit will have to be protected by an
external fast-blow fuse suitable to the loads connected and never
exceeding 3,15A.
