Sequence Information
NOTE: Normal sequences are in bold type, while abnormal sequences are not in bold type.
INITIATE HOLD: (AC Line Dropout) The LED indicates the system status, POWER, and that AC Line power
has momentarily dropped out. The RM7823A sequence will return to
STANDBY until the AC Line voltage has stabilized throughout the
INITIATE sequence.
INITIATE HOLD: (AC Frequency) The LED indicates the system status, POWER, and that line frequency
is faster than the expected value. The RM7823A sequence will not
advance into RUN until the line frequency returns to the proper value
(perhaps caused by using a 60 Hz device on a 50 Hz line).
INITIATE HOLD: (Low Line Voltage) The LED indicates the system status, POWER, and that low line
voltage has occurred. The RM7823A sequence will not advance into
RUN until the line voltage is at a sufficient level for proper operating
parameters.
RESET/ALARM TEST The LED indicates the burner status, POWER and ALARM. This
condition indicates that the reset pushbutton is pressed.
