Resetting the Oil Primary Control (continued)
5. Set the load temperature controller to call for heat.
NOTE: Main power should be ON and all hand-operated oil line valves open. When the call
for heat is detected, the oil primary control will perform a 3-4 second self-test which is indicated
by a "solid on" amber LED. After the self-test, the amber LED will turn OFF, and the burner will
start.
6. If flame is not established within 15 seconds (TFI-Try For Ignition), lock-out will occur.
Lock-out is indicated by a "solid on" red LED and closure of the alarm contacts (see NOTE
below).
To reset the control, repeat step 4.
7. Latch-up occurs if the control locks-out and is reset three times during a call for heat. Latch-up
is indicated by "solid on" red and amber LEDs.
8. To reset the control from a latch-up condition:
(a)
Push in and hold the reset button for approximately 40 seconds . The red and amber LED's
will go out.
(b) After approximately 10 seconds, the red and amber LED's will come back ON and will then
start to blink.
(c) After blinking ON/OFF for approximately 10 seconds, the red and amber LED's will go out.
Continue to hold the reset button for an additional 15 seconds, and then release the button.
(d) The burner will now start.
NOTE: Releasing the reset button at any time during this procedure (step #8) will cause
the unit to remain in latch-up, and you will have to start the procedure again.
9. When the load temperature controller opens, the burner motor turns off within 1.2 seconds.
10. If flame is lost during a normal run (after TFI), the burner motor turns off after 1.2 seconds. A
65-second recycle period begins, indicated by a blinking red LED. The control will restart
automatically after the recycle period.
11. Power loss during a normal run will cause the burner to safely shut down and begin a normal TFI
when power is restored.
12. If the burner will not restart at all (after having attempted oil primary control reset), contact your
Clean Burn dealer immediately.
NOTE: The oil primary control on the CB-551-H3 and CB-551-H5 Burners provides an extra set of dry
contacts to accommodate an externally-mounted horn, siren, bell, or other alarm device. The contacts close
when the control goes into either lock-out or latch-up mode. Because these are dry contacts, power must be
supplied from an external source. The contacts are rated for 24 VAC or DC at 2 amps.
