The Fireye EP100 Series programmer modules are used with the Flame-Monitor Burner Management Control System (E110). Several operational characteristics of these programmers are determined by six (6) dipswitches located on the side of the programmer. These characteristics include the operation of terminals 5 and 6 during PTFI and MTFI, extended purge timing, and the option that requires the 3-P running interlock circuit to be proven open at the start of the operating cycle.
