EP170 Fireye Programmer

The EP170 programmers provide start-up programming, safe-start check, and flame monitoring supervision. They insure open damper (high purge) prepurge, proof of low fire position, and fuel valve end switch safety checks. A running interlock circuit on the FLAME-MONITOR system constantly monitors the limit switches, air flow switches, and fuel pressure switches through the programmer. The programmer control is designed to initiate a safety lockout if any of these circuits are open at the improper point in the control cycle
