FS500 SERIES
Description
The FS500 Series flash rate is adjustable from 10 to 100 FPM.
A locknut is provided to hold selected flash rate. The long-life
electronic circuit combined with a quality electromechanical
relay provides flexibility and reliability in most applications.
Operation
Upon application of input voltage, the output relay is energized
and the ON time begins. At the end of the ON time, the output
relay de-energizes and the OFF time begins. At the end of the
OFF time, the output is energized and the cycle repeats as long
as input voltage is applied.
Reset: Removing input voltage resets the output and
the sequence.
