An output can be manually forced at any time by pressing
the Start/Stop key. The relay will energize for the set
time, and regeneration volume will return to its original
setting to begin counting down again.
Repair
The only field-repairable component on the FT520 is the
fuse. If failure is due to a cause other than a blown fuse,
it is necessary to replace the entire board stack. Contact
your distributor for information.
Fuses. The power supply and the analog output circuit
have fuse protection. The two fuses are on the board.
Replace the blown power fuse with a 250 mA, 5x20 mm
glass fuse, available from SeaMetrics or from Radio
Shack (or other electronic supply store). The DC power
fuse is a 1 Amp, 5x20 mm glass fuse.
