Resistance input for tap-changepotentiometer:

Ω when total resistance is 20 k Ω ) into tap-change positions.Pins 23 to 26 intended for connection to tap-change poten-tiometers. A current is connected via pins 23 and 26 and a resistance chain. The voltage drop that occurs per tap-change position can be measured via pins 24 and 25 (4-conductor circuit) or via pins 23 and 25 (3-conductor circuit). The standard version is a 3-conductor circuit. If a 4-conductor measurement circuit is required, it can be achieved at any time by changing the switching settings of DIP switch S and the connection.The resistance measurement circuitry consists of a program-mable current source to feed the measurement resistance and a voltage-measurement device to measure the voltage at the resistance. The measurement result is output with a resolution of 12 bits and a refresh rate of approx. 10 Hz (0.1 s).The measurement device has a broken-wire detection sys-tem. The parameters can be entered into an application menu using the keyboard (see operating manual). REG-DA voltage regulators that are equipped with characteri- stics D2 or D3 have only 8 binary inputs as standard, but also have a resistance input that can transform the resistance of the tap-change potentiometer (200
