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 electromagnetic relays, as the output relay of the sensor can be driven
directly with a detection signal.
• Wide voltage setting range with fine setting capability.

Set the must-operate voltage higher than the must-release voltage by at least 5% of the rated value.
Smoothing is required for the detected DC voltage.
The maximum applied voltage is 120% of the rated value.
Special models enabling a rated voltage of 220 V are available. The setting range for these models is 80% to 110%.

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.
