PPLICATION
Programmer PRG-SE-C-O2 equipment recommended for start, flame supervision and safe stop for
any type of burner for up to two stages of flame, in commercial applications or industrial and fuels gas
or light liquids, with a cycle of use do not continuum (on/off burner Period in less than 24 hours)
For use in closed combustion camera, the user should provide safe system of pre-purge
before each sequence of start, or require the programmer PRG-SE-C-O2 with purge timer coupled,
since that the times offered are appropriate for application
Entry for flame sensor for ionization See electrode sensors for ionization, line SEL-HT-I (standard) or
SEL-HT-E (electrode mounted on a drawing or sample of the client)
This roduct meets the requirements of the standard NBR 12313 of ABNT-review
Se t./2000.

Supply/frequency: 90 a 250Vca 50/60 Hz ± 3% or 24Vcc (-10 +20%).
NOTE: To su ly network CA, consisting of hase/neutral, should consider the
ossible need for its reversal (terminals 9 and 10), for flame sensor circuit not
lose sensitivity and therefore the ca acity to detect signal of flame. See below
diagram for the connections AC and DC.
