Blown Fuse
Erratic behavior (and/or) shutdown
: The 21.7690 will blow a fuse if the input
voltage is reversed. If this happens, first locate the wiring
fault, then replace the fuse with one of the same rating.
: The 21.7690 will
shut down if there is a short circuit condition on any one of
the strobe heads. If the electrical conductors connecting
the power supply to the strobe heads are exposed to water
a short circuit will result. The first sign is intermittent
operation, followed by complete shutdown of the strobe
system. To find the short circuit, unplug all strobe head
cables from the 21.7690. Test
cable/head at a time
until the problem is found.
