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.

Note: 1. Set the must-operate voltage higher than the must-release voltage by at least 5% of the rated value.

2. Smoothing is required for the detected DC voltage.

3. The maximum applied voltage is 120% of the rated value.

4. 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.
