The Model 50R
single-phase voltage monitor has a voltage-sensing
circuit which constantly monitors the single-phase
power for a low voltage condition. Single-phase
motors on fans, compressors, air conditioners,
heat pumps, well pumps, sump pumps and small
conveyor motors are all applicable to the Model 50R.
When a harmful condition is detected, the
MotorSaver’s output relay is deactivated after a
specified trip delay. The output relay reactivates
after power line conditions return to an acceptable
level and a specified amount of time has elapsed
(restart delay). The trip delay prevents nuisance
tripping due to rapidly fluctuating power line
conditions.
For more information see:
See Appendix A, page 68, Figure 7 for dimensional
drawing.
See Appendix B, page 76, Figure 28 for typical
wiring diagrams.
