REPLACEABLE FUSE
The following applies only to the YB110 controls operating at 120 VAC, 50/60 Hz:
The chassis/amplifier modules are designed with a field replaceable fuse to protect Terminals 5, 6, 7
and W against short circuit loads or mis-wiring. In the event the fuse becomes OPEN, the display
will indicate CHECK FUSE or the CLOSE DAMPER, AUTO and IGN LED’s will light. An OPEN
or blown fuse is a result of an over current condition on Terminals 5, 6, 7, or W. The over current
condition causing the fuse to OPEN must be resolved before another attempt to apply power.
For installations requiring CE certification
:
Only Fireye or a Fireye trained technician is allowed to replace the fuse.
All other installations:
The fuse is located on the printed circuit board containing the relays. To replace the fuse, remove
power from the system and remove the control from its wiring base. Using an appropriate tool,
remove the defective fuse and discard. Install a Fireye replacement fuse (P/N 23-197) or equivalent
10 amp fuse (e.g. Wickman # 1937-071-K). Re-install the BurnerLogix control in accordance with
the installation procedure detailed in a previous section.
The YB230 control contains a non-replaceable fuse and must be returned to the manufacturer for
repair or replacement.
