5.3.4 Expansion of the torque setting range
As supplied the device is setup for operation without a neutral conductor. In this
case the torque setting range is approx. 1:20.
If a larger setting range is required, two measures must be taken:
ƒ Connect the neutral conductor to the motor star point
ƒ Replace the resistor on soldering terminals (position R420, fitted with
22 kΩ resistor from the factory) with a 100 kΩ resistor.
