Operate Remote Indicator Light Automatic Reset when Voltage Rises 1.4 Volt Differential Between Relay Pull-In and Drop-Out
The LOAD MANAGER 1H is a
small economical assembly that monitors a D.C. voltage and operates a
relay when the voltage drops below its set point. This unit is unique
in that a special high hysteresis feature maintains the relay in the
energized condition even if the voltage rises again. This prevents the
load that has been shed from being reenergized until the sensed voltage
rises more than 1.4 volts above the set point. Voltage set point and
hysteresis are field adjustable. LED indicators are provided adjacent
to the terminal strip to indicate whether the system voltage is normal
or that the voltage has dropped below the set point. Installation
instructions that are provided with each unit contain a procedure for
readjusting the under voltage set point.
