Precaution when using LED-equipped reed switch
When a LED is connected in series to an input contact such as LED-equipped reed switch,
make sure that the voltage applied to the GM1 input terminal is greater than the ON voltage. In
particular, take care when connecting a number of switches in series.
■
Precaution when using two-wire type sensor
If the input to the GM1 does not turn OFF because of leakage current from the two-wire type
photoelectric sensor or proximity sensor, connect a bleeder resistor as shown below.
■
Precaution when using LED-equipped limit switch
If the input to the GM1 does not turn OFF because of leakage current from the LED-equipped
limit switch, connect a bleeder resistor as shown on below.
