Voltage Sensor LG2 CSM_LG2_DS_E_4_2 Compact, Economical Plug-in Type Voltage Sensing Relay • DPDT output contacts expand the application of the Sensor to wide-ranging fields including control, alarms, and indication. Voltage control is possible in the same easy manner as electro- magnetic relays, as the output relay of the sensor can be driven directly with a detection signal. Wide voltage setting range with fine setting capability. Model Number Structure ■ Model Number Legend LG2-@@ 13 2 1. Voltage sensor 2, 3.

Nomenclature LG2-DB VOLTAGE SENSOR RESET knob SET knob RESET SET 70to115% 75to120% VOLTAGE 12VDC Setting Method Operate Value Input the actual voltage to be set, and set the SET knob to the point at which the Relay operates. Release Value • With the Relay operating, turn the RESET knob counterclockwise as far as it will go, and adjust the voltage to the value to be set. Then, gradually turn the RESET knob clockwise until it reaches the point where the Relay is released. Note: After completing the settings, check the settings for the operate and release values by increasing/decreasing the input voltage. The LG2 can be used for undervoltage detection by using the RESET knob for the operate value and the SET knob for the release value. The Relay will normally be ON, however, and so the internal temperature will rise, and this will affect the product service life. 3 LG2 Dimensions Note: All units are in millimeters unless otherwise indicated.
