PPLICATION
PRG-E programmer is a programmer for start, flame supervision and safe stop recommended for
industrial or commercial use burner, with a discontinuous use cycle (on/off burner in a period less
than 24 hours), for power lower than 120 KW (100 000 Kcal/h). For use in closed combustion
chamber, the user must arrange a safe system of pre-purge before each start sequence, or ask a
programmer PRG-E with purge timer incorporated. Used in gas, oil or other kind of fuel burners.
The product fulfills the requirements of rule ABNT NBR 12313 – revision Sept. /2000. The
options are:
⇒ PRG-E- I – Input for flame sensor by ionization, when gas is used as fuel in burners that work
with this kind of sensor. See electrodes, sensors, line SEL-HT-I or SEL-HT-E (electrode
assembled under draft or sample from the special-client).
⇒ PRG-E-F - Input sensor infrared flicker of the flame.
Detecting presence of flame when using gas, oil or other fuel that causes flame light emission
with characteristics mentioned above.
See information of the sensors, line SEL-SV-F.
⇒ PRG-E- U - Input for ultraviolet radiation sensor, when gas, light oils or any kind of fuel that
stimulate flame with ultraviolet rays emission are used. See sensors; line SEL-SV-U.
⇒ PRG-E- L – Input for photo-resistance sensor of cadmium sulfide – visible radiation, when oils
or any other fuel that stimulate flame with yellow light emission in dark combustion chamber
are used. See sensors; line SEL-SV-L.

ECHNICAL DATA
⇒ Watch dog micro process – to provide safe failure.
⇒ Feeding 115 or 220Vac +10 -15% (phase / phase or phase / neutral non-grounded) - 50/60
Hz ± 3%.
⇒ Power Consumption: 4 VA
⇒ Fuses: Foresee two external fuses, one for internal circuits´ protection (100 mA delayed),
and other to protect outlet circuits in accordance to the foreseen load in the project,
respecting the boundaries of this specification. O PRG-E does note have internal fuse.
⇒ Protection against tension outbreaks.
⇒ Input for flame sensor: I, F, U or L (to order, see field code).
⇒ Input for the flame ionization. ultraviolet, visible light, infrared.
⇒ Minimum current of flame (uA-dc):
I U
2 / 200 /
NOTE: The cable of the sensor of fire should be installed separate from the other cables that
integrate the group of command of the burner. The best cable type recommended for this
purpose is it used for ignition.
⇒ Protection against failure due to short-circuit of the mass ionization sensor
⇒ With previous flame verification or false flame signal, before beginning the ignition.
⇒ Ignition time (Tig): 6 sec.
⇒ Purge time: 10 or 20 seconds (to order, see field code).
⇒ Maximum outlet currents: 2 A in 250 Vac (resistive) for the ignition N.A. contacts and vs of fuel ;
100 mA in 12 Vdc in the alarm version open collector or 1A in 250Vac for contact N.A. of relay
(isolated or with common in the feeding system)
