Hog Slat Inc. Newton Grove, NC USA May 2017 34 GROW-DISK ™ Feed System HSCD-100 Current Sensor The Grow-Disk chain disk system can over fill if the Grow-Flex feed system’s capacity is greater than the capacity of the Grow-Disk system. Overfilling will overload the Grow-Disk motor causing the thermal overload switch to kick out and/or premature motor failure. To prevent this from occurring, a current sensor has been installed on the Grow-Disk HSCD-100 Controller circuit board. This current sensor monitors the amp draw of the Chain Disk motor and controls a relay which is wired to the fill system. If the amperage exceeds the value defined by Max Current, it will temporarily turn off the GROW-FLEX™ AUGER System. As the Chain Disk system continues to empty itself the amp draw will decrease steadily. If the amperage drops below the defined Window values then the GROW-FLEX™ AUGER System will turn on. This ON/OFF cycling of the GROW-FLEX™ AUGER System will occur every few minutes until the Grow-Disk system is full. At this time, both the chain disk system and the fill system will shut off. When the amperage exceeds the value defined by critical amps on the Chain Disk motor load, the complete system is shut down and the controller goes into alarm mode.
