Note 1) LED is ON (signal output is ON) when neutralization performance has decreased.
Note 2) The emitter should never be cleaned while the power supply and compressed air are supplied to the product.
Note 3) If overcurrent is generated, the output signals of discharge, error, and maintenance limit current to protect the
output circuit. (Only the output where the overcurrent occurs)
