Selcon PRG-SE-C Technical Sheet

PROGRAMMER FOR START, FLAME SUPERVISION
PRODUCT: PRG-SE-C
Costumer Service 55 11 3019-1616
•
A
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 product meets the requirements of the standard NBR 12313 of ABNT-review
Sept./2000.

NOTE: To supply network CA, consisting of phase/neutral, should consider the
possible need for its reversal (terminals 9 and 10), for flame sensor circuit not
lose sensitivity and therefore the capacity to detect signal of flame. See below
diagram for the connections AC and DC.

NOTE: The cable of flame sensor must be installed separately from other cables that
are part of the command set of the burner. The best type of cable recommended for
this purpose is used for ignition.
