NOOOOOOO Those supervision relays are the 616L1-2 relays. That IS the ETS circuitry. If you raise the voltages up above top speed on P3/P7 on A3 (P1 A6 is top speed), there is no ETS protection. There are specific voltages to set them at. There are two 616L(x) relays.. P4 (A3) is the other one. Tell me what contract speed your car is in FPM and I will give the correct voltages for P3/P7 A3 and P4. Those pots control at what voltage the 616L(x) relays drop to allow the hoistway switch to stop the car.
