25 V or less (i.e., the OFF voltage for the ZEN) is 5 mA, as shown
in the residual voltage characteristic graph.
From the formulas given above,
R1 ≤ 25 V AC/1.7 mA= 14.7 kΩ
R2 ≤ 85 V AC/5 mA = 17 kΩ
The bleeder resistor must thus be 14 kΩ.
The Sensor output current in this case would be 100 VAC/14 kΩ,
or 7 mA. This satisfies the Sensor's control output range of 5 to
300 mA.
The bleeder resistor capacity is calculated as shown below and
must be 3 W.
