The Fireye EP260, EP270 (early spark termination), or EP265 (pilot stabilization) programmer mod- ules are used with the FLAME-MONITOR Burner Management Control System (P/N E110). Sev- eral 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 inter- lock 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 pro- grammer. The programmer will recycle if the running interlock circuit (3-P) is opened during the fir- ing cycle.
The programmer module will de-energize all fuel valve circuits within four (4) seconds (max.) fol- lowing 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 commu- nicate with the E500 via the standard ED550 cables to provide backward compatibility.
All EP programmers come equipped with built-in modbus-rtu communications. Refer to bulle- tin E-1101 for complete details.
The programmer is the heart of the FLAME-MONITOR System and features a plug-in design for ease of installation. It is micro-processor based and stores burner cycles, burner hours, system hours, and lockout history (with burner cycle and burner hour time stamp) which are accessible via the ED510 alpha-numeric display, E500 Communication Interface or Modbus Communications. If replaced, the new programmer card will begin accumulating a new history.
Refer to Bulletin E-1101 for detailed information on the FLAME-MONITOR System.
