114 / 121 page  B7AP B7AP 112 Precautions General Precautions Be careful when touching the B7AP-S1 Power Coupler during op- eration because the surface temperature of the B7AP-S1 Power Coupler will rise approximately 20 °C after the B7AP-S1 Power Cou- pler starts power transmission. The surface temperature varies with the load of the sensing device connected to the B7AP-M1 Power Coupler and the transmission distance. Correct Use Handling Use the B7AP-S1 and B7AP-M1 Power Couplers with the available B7A Link Terminals. Refer to page 21, B7A Models. The M7E-12 jj Display Unit, M7E-20jj Display Unit, and B7A Link Terminals with an I/O delay time of 3 ms cannot be used with the B7AP-S1 or B7AP-M1 Power Coupler. Use the LOAD-OFF model for the B7A Output Unit to be connected to the B7AP-S1. When using a model that allows selection of error processing, set to the LOAD-OFF mode. This turns OFF signals right before an occurrence of a transmission error and prevents un- expected signal transmission when the transmission error is cleared. Separate the Power Couplers 8 ±1.5 mm min. away from each other. The distance between the Power Couplers on standby must be 30 mm or more. 30 mm min. Do not supply power to the B7AP-S1 or B7AP-M1 Power Coupler while connecting the Power Couplers to the B7A Link Terminals. Connect the Power Couplers to the B7A Link Terminals correctly, otherwise the internal circuits of the Power Couplers may be dam- aged. The SIG terminal must not contact with the power supply terminals, otherwise the internal elements may be damaged and normal trans- mission may not be possible. Brown(+) Black(SIG) Blue(–) Brown(+) Black(SIG) Blue(–) Brown(+) Black(SIG) Blue(–) Correct Incorrect Incorrect Contact Wire the cables of the B7AP-S1 and B7AP-M1 Power Couplers through independent metal conduits to prevent the Power Couplers from being influenced by noise if there are power or high-tension lines nearby. Test the Power Couplers and make sure that the Pow- er Couplers operate normally before they are put in actual opera- tion. Metal conduit Power or high-tension line Correct Incorrect Do not subject the head of the B7AP-S1 or B7AP-M1 Power Cou- pler to excessive shock with hard objects. Do not use the B7AP-S1 or B7AP-M1 Power Coupler outdoors un- less it is properly protected. The B7AP-S1 and B7AP-M1 Power Couplers are products meeting the requirements of IP67. The B7AP-S1 or B7AP-M1 Power Cou- pler cannot be, however, used in water or oil. Keep the heads of the B7AP-S1 and B7AP-M1 Power Couplers free from dust, otherwise improper signal or power transmission may re- sult between the Power Couplers. Mounting Use nuts and serrated toothed washers and tighten the nuts to mount the B7AP-S1 and B7AP-M1 Power Couplers. The tightening torque applied to each of the nuts must be 39 N S m maximum. The mounting position will change and improper signal or power trans- mission may result between the Power Couplers if the nuts are not tightened properly. 39 N Sm max. Transmission Distance for Stable Signal and Power Transmission The B7AP-S1 Power Coupler has a gauge that is used to adjust the transmission distance between the B7AP-S1 and B7AP-M1 Power Couplers. Use the gauge to adjust the transmission distance to 8 mm, make sure that the green operation indicator of the B7AP-M1 Power Coupler is lit, and the B7A Output Unit has no error output before operating the Power Couplers. Gauge Operation indicator 8 mm Monitoring Transmission Status Judge from the power supply/error indicator and error output of the B7A Output Unit whether the B7AP-S1 and B7AP-M1 Power Cou- plers are facing each other properly. The error output of the B7A Output Unit will be ON when the B7AP- S1 and B7AP-M1 Power Couplers are not facing each other proper- ly. |
