R4075E DUAL INDUSTRIAL FLAME SAFEGUARD CONTROL (FIG. 63) The R4075E consIsts 01 2 controls on 1 chassis 10 pro- vide Independer1t ~rvislon of 2 indusUial burners. 11 can al$O be used for redundanl safely conlrol systems or for l1JaI·fuel applications. With 2 controls on' chassis, the mOUFllinQ space r9QJlred Is only hatf (hal previously Each control is similar to the R4075C, and thus is ac:lapled for the 'Same family of plug-in name sIgnal amplifi· ers developed for the R4140. Any ccrrt>inalion 01 standard and/or sal1·checking flame detection system can be used by mi;ling or matching the amplifiers. For BKample, a flame red can be used 10 delecl Ihe pilot, and a self-checking C7012E or F Ultraviolet Flame Deleclor can be used for the main burner flame. Since all amplifiers are plug-in, Ihe detection rJ'\C:lClI3'can be changed anytime after Jnstallation. Because terminal designations for lhe R4075E are unlQJ9, II requires a special Q295A1054 Wiring Subbase. The R4075E is available in 120 and 220 voll models. SEQUENCE OF OPERATION FOR THE R4075E (FIG. 64) The q:>eration of the 120 volt model o1lhe R4075E will be described. The sequence 01 operalion for the 220 voll model is the same; it just has 2 addilionallransforrners to provide 120 volts for the shullers on C7012E or F Purple Peeper Ullraviolet Flame Detectors. The schematic ill Fig. 64 shows all relay conlacls in the de-enerQized posl- lion. Refer 10 file 8eq.Jence 01 {)peralion on the following 2 pages.

The A4138C is available in 120, 220, and.24O volt rtlOdeIS; the A4138D Is available only in a 120 vol'model. SAFETY FEATURES The A4138C and D provide a Safe Start Check for a flame, or a condition simulating a flame, at startup. If the flame"relay 2K is pulled in before the STAAT button is pressed• .2K.2 is open, preventing the load relay 1K from pulling in.
