Electrical System – 5000

•Digital input from control sensors.

•The figure with the fourth highest value is active (marked with an arrow).

14.7 Part number

•Press and hold S18 while turning S17 to “ON” position.

•Press S18 until Pn = part number is displayed.

•You have now selected Pn = part number and the symbol ”D” is lit as an indication of what is now shown in the display. Initially, Pn = number is displayed for the component’s entire unit.

•By scrolling with L1, you can get the following information:

•SPn = Part number for software.

•HPn = Part number for hardware.

•HSn = Serial number for hardware.

14.8 Transistor panel

14.8.1 General

Curtis 1243 is a regulator that controls shunt motors. What primarily controls the speed is the variation in the voltage in the rotor. The voltage is varied by means of pulse width modulation (PWM). This also includes variation in "on" time for the MOS transistors that regulate the rotor current.

The rotation direction is changed by changing the polarity in the field winding (S1-S2). The regulator is equipped with a transistor-fitted fourquadrant bridge for the field winding and a single-quadrant bridge for the rotor winding.
