(1) Facilities that use combustion safety equipment must be designed in compliance with relevant laws, standards, safety guidelines, and the
like. If this device is used outside Japan, please observe the local laws and standards.
(2) This device monitors for failures of the relay contacts connected to combustion-related loads (IG, PV, MV). Error E09 is output if, due to
a ground fault or incorrect wiring, voltage is generated at the terminals connected to the loads even though this device is not outputting a
load. If E09 occurs after this device is installed, recheck the wiring and eliminate the cause of the error.

AUR890
Burner Controller
Overview
AUR890 burner controllers were developed to replace the
RA890, and are designed for batch operation of combus-
tion equipment (at least one start and stop in a 24-hour
period). In combination with an AUD100 series Advanced
Ultraviolet Flame Detector or a flame rod, the AUR890
automatically executes ignition, flame monitoring, and fuel
shutoff for ON/OFF-controlled gas burners or oil burners.
Features
•7-segment LED display shows the step in the combustion
sequence, alarm codes, and flame voltage.
•The presence/absence of a f lame signal or lockout is
shown by LED indicators.
•If lockout occurs due to ignition failure or flame failure,
combustion cannot restart without a manual reset.
•If there is a false flame signal during startup, the control-
ler will be locked out.
•Conducts self-diagnosis of the internal control relay cir-
cuit.
•A base unit, Q890A100, is available for use when re-
placing the RA890.
To use this Q890A base unit when replacing the RA890,
install the Q890A base unit under the sub-base
(Q270A1024) of the RA890F/G in the same mounting
holes. Then, attach the cables that were connected to the
Q270A1024 sub-base to the new base unit. The termi-
nals have the same numbers.

When the power is turned OFF, the 7-segment LED display on the front

* The AUR890 turns the main valve ON after the standby process for normal combustion. This feature does not allow the main valve to be turned on immediately after ignition in order to prevent the flame from being blown out. During the standby
process for normal combustion, if the time set for external timer TM1 is complete and the contacts are reversed, the supply of power to the pilot valve and main valve may be interrupted for a moment.
Whenever a flame is detected just before completion of the time set for external timer TM1, ignition is delayed. Adjust the burner so that it ignites
reliably at least one second before the time set for external timer TM1 passes.
