This range of electronic gas burner control systems has
been designed specifically for atmospheric and fan assisted
burners for intermittent operation (systems for nonpermanent
operation ).
TECHNICAL DATA
Supply Voltage: 230V-50/60Hz
Operating temperature range: -20°C +60°C
Ambient humidity: 95% max at 40°C
Times:
-Prepurge or waiting time (TW): 1,5/3/5/10/20/30/40 s
the waiting time for type SM152 is: 3/5/10/20/30/40 s
-Safety time (TS): 3/5/8/10/20/30/40/50/60 s
-Drop out time on running flame failure: < 1 s
The times given on the burner control label correspond
to
the values guaranteed. The actual values differ slightly
from
the values given, pre-purge and waiting times are in fact
longer and safety time shorter than their nominal values.
