10. BOTTOM VIEW TO 92 RY 3 2 Current Switch The Current Switch CS from CR Magnetics is another popular sensor for the WEL Page 7 of 39 As its name implies the CS is a switch that turns on when it senses current This is a great way to detect when a device like a pump or heater element is on it doesn t actually measure power usage The beauty of this kind of sensor is that there is no electrical connection with the actual device being monitored so it s very safe One of the power conductors of the device being monitored is passed through the hole in the CS When more than 350ma of AC current is detected in this wire the CS closes an optical output which can be detected any of the 8 run monitor inputs on the WEL Each CS has two output wires The black wire is a common ground that is connected to either of the run monitor GND inputs on either end of the J2 terminal strip on the WEL The red wire is the actual signal wire and each of these is connected to a separate run monitor input 1 8 The following photo shows 2 CS s connected to the WEL as Run inputs 7 amp 8 If it s not convenient to wire a CS directly to the WEL or if you need to monitor more than 8 devices have b developed a 1 wire interface for the Current Switch CF Bo This interface is wired to the CS and provides the standard Black Yellow wire pair that can then be Fa Ra R5 y 2 ae DONDE connected anywhere on the 1 wire bus
