Caution: On power up, the pump will start
automatically. Do not turn on the power to the control
module unless you are sure that the pump is ready to
operate.
5.0 Current fold back:
The V300 incorporates a current fold back feature that
prevents motor heating in case of a jammed pump.
This current fold back feature makes it unlikely to blow
a fuse under normal and stalled motor conditions.
This design provides maximum torque to handle tem-
porary loads yet remains safe in a stalled condition for
extended time frames. The fuses are intended to pro-
tect the mains from an internal failure of V300 power
circuits. In the unlikely event a fuse blows, it should be
replaced with the exact replacement type indicated in
"Fuse Replacement" (See section 6.0).
6.0 Fuse Replacement:
The V300 utilizes a universal double fusing arrange-
ment which allows the safe use in North America as
well as European Communities.
The fuse holder will not open without removing the
power cord. Once the power cord is removed, simply
pry up the fuse cover at the indicated screwdriver slots,
swing open the cover hinged towards the power sock-
et. Then remove the fuse holder block by pulling it
straight out exposing the fuses. Always replace both
fuses with the same type and rating even if only one
has blown. The V300 requires two (2) 5x20mm 1 A -
250 VAC Time Lag fuses. If the V300 blows these new
fuses, then the unit must be taken out of service and
returned to FMI for repair.
