Answer the following statement(s) true (T) or false (F)
1. The pilot control device shuts down at a loss of power. 2. The phrases no-voltage drop-out, or two-wire control circuit should indicate a possible safety concern to the electrician, because a mechanically held closed pilot device could automatically restart the load motor when the power is restored. 3. A differential control device is a two position (on/off) switch that actuates when the measured medium reaches either of the two pre-determined extreme high or low range values, with a dead zone in between where the switch does not change states. 4. It is extremely uncommon to find differential switches for pilot devices in these motor control circuits. 5. Differential controls provide a mechanical means that acts like a mechanical holding circuit.
