(2) Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse. Care must be taken not to touch the light detector surface. * Conduct cleaning as follows. (3) Cleaning Solvent dip cleaning : Solvent temperature of 45 C max., dipping time : Within 3 minutes Ultrasonic cleaning : Elements are affected differently depending on the size of cleaning bath, ultrasonic output, time, size of PWB and mounting method of elements. Conduct trial cleaning on actual operating conditions in advance to make sure that no problem results. * Use the following solvents only. Solvents : Ethyl alcohol, methyl alcohol or isopropyl alcohol (4) To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc. (5) Do not apply unnecessary force to the terminal. (6) Example of recommended external circuit (mount outer mounting parts near the sensor as much as possible.) R1 VCC IS1U60 Ve + C1 GND (Circuit constant) R1 = 47 5% C1 = 47 F GND Vout Vout |
