Microcontroller
What makes this winch smart is it's state of the art digital electronics controller. The controller is based on a Microcontroller Unit (MCU) which is a very small computer system in one chip. The MCU is controlled by a software program (ROM) which monitors all aspects of the winch's operation. Included in this program are some 'smart' fail-safe features that can protect the winch from problems that may occur with your yacht's electrics or sheeting system. To fit all the features into the controller, surface mount technology is used on a double sided printed circuit board.
PI Controller
PID is a control method for many different types of dynamic systems. Servo systems generally use PID to efficiently and acurately drive the output to the desired setpoint. However in some systems PI control is sufficient. For the J series, the D term has been replaced by a user adjustable expo function which gives the ability adjust the final aproach to the set point without compromising overall acceleration/decelaration for most of the travel. The P term is also user adjustable and is called servo gain in setup 2. This combined with expo can be used to slow the overall speed of the winch if desired.
Battery Testing
The SmartWinch can monitor the battery for low voltage. If the voltage is below the warning level a warning signal (5 rising tones) will sound when the winch is switched on. If, during normal operation the voltage falls below the shutdown level, the winch will drive to the low battery failsafe position and hold there until the battery is replaced or voltage recovers. See Table 1. Default is battery monitoring OFF.
Low Battery Failsafe Position
The default low battery failsafe position is booms half out. But this is only true if using a standard spool type drum. If a spiral drum is used then this position would be closer to full in and could make it difficult to get the boat ashore. To compensate for this the low battery failsafe position is also adjustable so you can choose whatever position you wish between full in and full out.
Input Deadband
Input deadband is the amount dithering in the Rx signal that a servo can tolerate without responding to by constantly jittering. This is adjustable from 0.8 to 10 microseconds. Deadband adjustment allows the optimization of TX fine trim control. The default setting is 2 microseconds.
Voltage Protection
For protection of the electronics from over or under voltage conditions the circuit will disable itself when the supply voltage is above 9 Volts or below 3.8 Volts.
Overrun Protection
Once setup 1 has beed performed, the winch is programmed to ignore signals which are above maximum and below minimum pulse width of thet transmitter. This means that should interference cause the receiver to send signals outside the normal range for that transmitter, the winch will just ignore those signals. It will not try to travel closer than close hauled or beyond square running positions.
