Hog Slat Inc. Newton Grove, NC USA May 2020 REV A8 18 GROW-DISK™ Feed System SETTINGS: Press button to access the SETTINGS pages. These settings are for the control of the chain disk system, auger motor, feed sensor, actuator/e-valve and all timer delays necessary to run the system. Proper set-up of the system is essential to prevent common problems such as over-loading, pre-mature cycle completion, or chain and other system component damage. The below information provides not only display functions but also guidelines to each setting and how they should be applied. SETTINGS 1 of 3: 1. MAX AMPS: Default 6.0A - Sets the maximum amp draw of the chain disk motor at which point the auger motor stops delivering feed into the system. Setting is based on chain disk drive motor rated amps. Set value equal to max amp rating of chain disk drive motor found on motor nameplate. 2. MAX AMPS DELAY: Default 04:00 minutes – amount of time the chain disk drive motor is allowed to run equal to or greater than the MAX AMPS value. If time is exceeded, controller faults and stops running. Causes can include feed delivery rate of the auger system is greater than feed delivery rate of the chain system or load of the system when empty is too high indicating other problems causing load not related to the amount of feed in the feed pipe. 3. WINDOW AMPS: Default 1.0A – The amount of amps the chain disk drive motor has to drop before auger motor turns on to deliver feed. The amp reading of the chain disk drive motor has to drop below the value of MAX AMPS – WINDOW AMPS. For example 6.0 – 1.0 = 5.0 therefore the chain disk drive motor amp draw will have to drop below 5.0A before auger comes on or back on. 4. CRITICAL AMPS: Default 8.0A – Amp draw value of the chain disk motor at which point the system is shut down (Fault). This would indicate a problem with the system and this function is in place to protect the drive motor. Works in conjunction with the CRITICAL AMPS DELAY. Set value to approximately 1.33 times the rated motor amps. For example rated amps equal 6.0A, therefore 6.0 x 1.33 = 8 .0 AMPS. 5. CRITICAL AMPS DELAY: Default 00:10 seconds – Maximum time the chain disk drive motor is allowed to operate above the CRITICAL AMPS setting. Risk of damage to the system can occur if this value is increased. Running motor above critical amps will damage the motor and is a strong indicator there is a serious issue with the chain disk system causing excessive load. 1 2 3 4 5 6 7 13 14 Press + or – to increase or decrease value.
