Step Action
1 Turn the HVSD potentiometer fully clockwise.
2 Monitoring the test points (V+, V-), adjust the float potentiometer FLT to
the desired HVSD level.
3 Turn the HVSD potentiometer slowly counterclockwise until the rectifier
shuts down. The test point voltage shall start decaying to 0 volt.
4 Turn the float potentiometer counterclockwise, two full revolutions.
5 Cycle the AC breaker OFF/ON. The unit shall power up with the return of
the float voltage on the test points.
6 To verify turn the float potentiometer slowly clockwise until the unit
