20 cautions during series or parallel connection (1) series connection (and connection) when connecting two or more proximity sensors in series, er- roneous output (1 to 3ms) may occur without the rated current being supplied to each of the sensors. for this reason, series connection of proximity sensors is not recommended. however, if proximity sensors must be connected in series, a resistor of 10k must be provided in parallel to each o f the sensors. however, note that the maximum leakage current in a series connection will be 3.5ma. operation lag also will occur, resulting in increased voltage drop, and the operation indicator lamp will not light. operation lag = 40ms (number of series connections ~ 1) voltage drop = voltage drop of single sensor number of series connected sensors (2) parallel connection (or connection) when connecting two or more proximity sensors in parallel, leakage current increases as follows, and may result in faulty load restore. (leakage current = leakage current of single sensor number of series connected sensors) when two o r more sensors turn on in a parallel connection, one (or some) of the sensors may not indicate operation. this is not an abnormality. relay loads the voltage drop of the fl7m series is 3.3v (shielded t type: 3.5v). pay attention to this voltage drop when using a relay load. (with 12vdc relays, switching is not possible.) operation at power on after the power is turned on, it takes 40ms or less until the proximity sensor is ready for sensing. when the load and the proximity sensor use different power supplies, be sure to turn the proximity sensor on before turning the load on. influence of leakage current minimal current flows as leakage current for operating the cir- cuits even when the proximity sensor is off. take sufficient care when restoring connected loads. minimum cord bending radius (r) the minimum bending radius (r) of the cord is 3 times cord di- ameter, take care not to excessively bend the cord beyond this radius. also, do not excessively bend the cord within 30mm of the c ord lead-in port. restricions on u se this product has been designed, developed and manufactured for general-purpose application in machinery and equipment. accordingly, when used in applications outlined below, special care should be taken to implement a fail-safe and/or redundant design concept as well as a periodic maintenance program. - safety devices for plant worker protection - start/stop control devices for transportation and material handling machines - aeronautical/aerospace machines - control devices for nuclear reactors never use this product in applications where human safety may be put at risk.
