Amplifier Units 1 ●Designing Operation after Turning Power ON The Amplifier Unit is ready to operate within 200 ms after the power 2 supply is turned ON. If the Sensor and load are connected to power supplies separately, be sure to turn ON the power supply to the Sensor first. To remove the connector, press down on the locking lever and pull the Cleaning connector out. Do not use thinner, benzene, acetone, or kerosene. If the filter on the Lock lever front of the sensor becomes soiled with dust, oil droplets, or other materials, (a) Use a blower brush (used to clean camera lenses) to blow large dust particles from the surface. Do not blow the dust away with your mouth. (b) Use a soft cloth (for cleaning lenses) with a little alcohol to remove the remaining dust. Note: Do not use a scrubbing action when cleaning as a scratch on the filter could result in the Sensor malfunctioning.
