The RM7897A and RM7897C are microprocessor-based integrated burner controls for automatically fired gas, oil, or combination fuel single burner applications. The RM7897A and RM7897C systems consist of a relay module, subbase, amplifier, and purge card. Options include a 2-line VFD or 4-line LCD Keyboard Display Module, Data ControlBus™ Module, remote display mounting, Expanded Annunciator, or Modbus module. Functions provided by the RM7897A and RM7897C include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics, and troubleshooting. The RM7897 adds a proof of closure input to the standard primary control function of the RM7895/RM7896 product. It also introduces a blinking fault code function on the POWER LED during Alarm shutdown and programmable postpurge using the S7800A1142 Keyboard Display Module (KDM). The RM7897A1002 offers selectable pilot operation, intermittent on terminal 8 or interrupted on terminal 21. The RM7897C1000 provides interrupted pilot and delayed main valve operation for 2-step firing (Low-High-Low) applications. The RM7897C1018 features a 4-second MFEP (main flame establishing period).
