I have been provided a task for reverse engineering. The data provided to me are Relays, LEDs and Switch connections and below mentioned data.
I am having some problem in mapping mains voltage to relays state.
I want to know whether I have to turn ON RL1 if mains voltage is < 110V or should it be ON if it is between 110V and 131V ?
I think I should turn ON RL1 if mains voltage is < 110.
If I am wrong correct me.
* AC input 110V - ADC 1.55V
* AC input 131V - ADC 1.86V
* AC input 135V - ADC 1.9V
* AC input 152V - ADC 2.17V
* AC input 156V - ADC 2.21V
* AC input 173V - ADC 2.49V
* AC input 176V - ADC 2.50V
* AC input 200V - ADC 2.90V
* AC input 205V - ADC 2.94V
* AC input 238V - ADC 3.49V
* AC input 242V - ADC 3.51V
* AC input 274V - ADC 4.10V
* AC input 280V - ADC 4.14V
* AC input 300V - ADC 4.50V
*Input 280V = Output 0V. High Cut start. RL2 + RL3 on.
*Input 274V = output 230V, RL2 + RL3 + RL4 on.
*Input 242V = Output 204V. RL2 + RL3 + RL4 on.
*Input 238V = Output 233V. RL2 + RL4 on.
*Input 205V = Output 201V. RL2 + RL4 on.
*Input 200V = Output 235V. RL3 + RL4 on.
*Input 176V = Output 208V. RL3 + RL4 on.
*Input 173V = Output 238V. RL4 on.
*Input 156V = Output 216V. RL4 on.
*Input 152V = Output 239V. RL1 + RL3 + RL4 on.
*Input 135V = Output 212V. RL1 + RL3 + RL4 on.
*Input 131V = Output 241V. RL1 + RL4 on.
*Input 110V = Output 0V. RL1 on. Low cut start.
