The Fireye EP260, EP270 (early spark termination), or EP265 (pilot stabilization) programmer modules are used with the FLAME-MONITOR Burner Management Control System (P/N E110). Several operational characteristics of the programmer (with Engineering code 28 or later, e.g. 9414-28) are determined by six (6) dipswitches located on the side of the programmer. These characteristics include extended purge timing (dipswitches 3, 4, 5), and the option requiring the 3-P running interlock circuit to be proven open at the start of the operating cycle (dipswitch 6). Dipswitches 1 and 2 are inactive.
The EP260, EP265, EP270 programmers provide start-up programming, safe-start check, and flame monitoring supervision. They insure proof of low fire position, and fuel valve end switch safety checks. The control is designed to initiate a safety lockout if any of these circuits are open at the improper point in the control cycle. 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 will recycle if the running interlock circuit (3-P) is opened during the firing cycle.
The programmer module will de-energize all fuel valve circuits within four (4) seconds (max.) following a flame failure [two (2) seconds for the EP265], or at the end of the pilot trial for ignition period if no flame is detected. An alarm circuit will be energized following a safety lockout.
The programmer module includes an RJ45 style connector to interface with an integral or remote alpha-numeric display (P/N ED510). It includes two (2) additional RJ style connectors to connect to an E500 Communication Interface in a multi-drop configuration. The programmer will also communicate with the E500 via the standard ED550 cables to provide backward compatibility
