The SCP12 is the heart of the Powerpilot and all other units are linked to it. It decodes the information from the heading sender and calculates the heading, acts upon user commands sent from the control unit, reads the rudder position from the linear feedback unit and controls the drive unit.
- Page 18 SIMRAD Issue 1.2 18/07/03 Active Braking. To stop the motor of the pilot drive unit “Active Braking” is used. A short circuit is applied across the motor , by IC4b,c,d and IC5b, to provide a back EMF to oppose the motion of the motor.
- Page 19 SIMRAD Issue 1.2 18/07/03 Switches. Microprocessor ports P1.0 – P1.4 are connected to switches S1 – S5 and are normally high. When a switch is pressed the relevant line is pulled low and the microprocessor actions a specific task. Bus Circuitry. The Powerpilot system is interconnected via a single line Rx / Tx data bus. The bus control is formed by IC3 and its associated components.
- Page 20 SIMRAD Issue 1.2 18/07/03 Supply and Regulation. The SLF12 is designed to work from a 12 V source. The input terminals are filtered for EMC purposes by L1, L2 and C1. Protection against incorrect polarity connection is provided by D1 with protection against over-voltage spikes provided by ZD1.
