The UV-OV Relay Precise - Programmable Voltage Detector monitors the battery system voltage and detects both over voltage and under voltage conditions. The under voltage trip point is programmed by the use of 3 "DIP" switches, which provide for 8 possible settings ranging from 11.44 Volts to 13.01 Volts. Over voltage trip point programming is done similarly with 8 possible settings ranging from 13.66 Volts to 15.06 Volts. These "DIP" switches are easily accessed by removing a snap-on window cover at the top of the unit. Heavy duty relay contacts are provided for both conditions. These contacts may be hooked up to warning devices indicating abnormal conditions. Three LED indicators are provided under the snap-on cover for system trouble shooting, yellow for under voltage, green for normal, and red for over voltage
