Operation

Speed Sensing

Supply voltage must be provided continuously during operation and a proximity switch or sensor to sense the speed must be installed. The supply voltage to the sensor is available from the CLR. The CLR monitors the pulse rate received from the sensor. Based on whether the frequency is over or under the adjustable set point, the relay’s output will be energized or de-energized. For under speed sensing, the relay output will be energized if the sensor pulse rate is greater than the set point, indicating an “at speed” condition. It will de-energize if the speed slows and the pulse rate drops below the set point. A 0.5 second time delay avoids rapid cycling of the output contacts.
