The Comparator icon performs a comparison between its X and Y inputs and Outputs a Logic (True/False) signal depending on the result of the comparison. If the X input is greater than the Y input, the Output is True. If the X input is less then the Y input, the Output is False.
In the above net, when the temperature of the engine oil exceeds 130C, the relay output will be energized. The Comparator has been configured with hysteresis of 10 degrees. When the temperature drops to below 120C
NOTE: Optionally utilize the Latch icon between the Comparator and the Alarm to latch the Alarm ON once it turns on.
