WINCH MOTOR CONTROLLER
 ASSEMBLY 199-01-MA
   FEATURES

The unit has been designed to be rugged, reliable, and include all the safety features which I wish we had put into our previous versions.
 

RADIO CONTROL NOISE PROTECTION
The radio remote control devices we use to perform the radio control functions uses digital encoding to prevent random electrical noise or your neighbors similar unit from interfering with proper operation. Despite this, most radio receivers can be fooled and may provide an output when no valid signal is being received. The Controller implements a time out feature which disables the radio control inputs if no radio commands are received for 5 minutes. This prevents radio noise from operating the motor while you are out in the boat. The radio may be enabled again without going to the controller by sending a special sequence of commands from the transmitter hand unit. The timout feature does not affect the manual inputs which are always functional even when the radio control has been disabled.
 

LIMIT SWITCH INPUTS
Limit switch inputs are provided to prevent the Controller from operating the motor when activated. Two limit switch inputs are provided, one for each direction (IN and OUT). When the IN limit switch input is activated it prevents the motor from being activated in the IN direction. The OUT limit input does the same thing for the OUT direction. These inputs are intended to be wired to external sensors which can prevent the dolly from being moved in the direction which may cause equipment damage or personal injury . An example of one of these conditions would be to prevent the dolly from coming off the rails at either end.
 

HOME SENSOR INPUT
When the boat is brought in for the day the controller should be turned off to prevent any malfunction from activating the motor. A home sensor is installed to detect when the boat is fully inside the the boathouse. When this sensor is activated the controller automatically turns its power off.
 

MOTOR DIRECTION DELAY
Electrically reversing motors must stop rotating before the direction of the motor can be changed. If the controller is requested to to reverse the motor direction before the motor has stopped rotating the motor will continue in the original direction. The reason for this is that the start winding is disconnected by an internal centrifugal switch once the motor starts to rotate. If the motor is re-energized before the centrifugal switch reconnects the start winding its direction can not be changed. The controller implements a time delay to allow the motor to stop when switching directions. Due to the pull of the dolly/boat the motor will take longer to stop when operating in the OUT direction. Because of this the controller has a longer delay when switching from OUT to IN.
 

RELAY FAILURE DETECTION
Although the controller uses very reliable high current relays which are rated for switching motor loads they are still mechanical devices which can stick or fail. The controller monitors the operation of the relays to insure they are operating properly. If a failure is detected the controller will turn off to prevent undesirable operation from causing damage or injury.
 

HEAVY DUTY COMPONENTS
The motor and supply connectors are heavy duty reliable electrical connectors which are properly rated for the voltage and current required. The motor control relays are CSA and UL rated for one horsepower motor loads.
