An amplifier that is special tailored to operate in car washes (washing gantries). It differs from other light barriers of the ISG series in 4-fold frequency switching for better decoupling of the detection ranges if the mounting is very close. Furthermore it differs in an increase of firm capacity during high setting. The light/dark switching is realised via a bond bridge in DIN-socket.
The special programming of this device enables perfect operation in the difficult environmental conditions that exist in the car wash industry. In particular, there are problems with wet and specular walls and floors, reflective vehicle roofs or sudden spray. On one hand, the device is sensitive enough to detect curved windshields and on the other, it is powerful enough for wheel detection during simultaneous high pressure under body and side washing.
At the push of a button, the device shows information about sensor alignment and wiring, such as wire breakage and short-circuits. Four level settings allow an adjustment to different operating conditions. The alarm output indicates that the sensors are too contaminated. This compact single-channel amplifier must be mounted on a 11-pin DIN rail socket. A relay output for high switching loads is included. |
