ClariSea Smart Controller
The ClariSea unit features a smart controller that allows for both automatic and manual advancement of the fleece roll. It also provides visual and audible alarms if a potential error is detected during operation.
Smart controller buttons
Play button: Press and hold to manually advance the motor and roll on the fleece.
Alarm button: Press the alarm button for 1 – 2 seconds to turn off the audible alarm. The alarm condition will still be present with the Red LED flashing. The automatic advance of fleece will be disabled, however, the play button will still function for manual fleece advancement. Pressing the alarm button for 5-7 seconds will fully reset the controller, clearing the alarm state and restoring the unit to normal operation mode. Disconnecting power for 30 seconds will also reset the controller and clear the alarm state.
