If the machine has digital temperature controllers and are wired and configured for communication with the HMI touch screen, this box will need to be checked. This essentially means that as the grain's moisture goes up, the dryer will slow down and as the grain's moisture goes down, the dryer will speed up. Discharge Moisture Low Limit The discharge moisture low limit alarm set point is a discharge moisture value that will trigger an alarm when the value drops below the discharge moisture low limit set point for a duration of 5 minutes. 112 Critical High Discharge Moisture The AccuDry moisture control system has experienced critical high discharge moisture. Access to these screens is accomplished by following the login procedure previously outlined in this manual. Once the Calibrate button is pressed, the new slope will be calculated as well as the new calibration temperature which is taken as the current grain temperature measured from the sensor. This is a temporary state and it will revert to Manual mode after 25 minutes as a safety precaution. A tabulation of data for all dryer models is shown on the next page with VFD frequency, metering speed, and discharge rate (bu/hr and metric tonnes/hr) for 0% - 100% in 10% increase. This also determines the total amount of grain dried which is viewed when looking at the Dryer History screen. After a few minutes, you will see the results of the adjustment and your moisture display should be more consistent with your 3rd part testing equipment. If the machine is equipped accordingly, enabling the Main Auxiliary Alarms checkbox will tell the system to monitor the additional alarm inputs previously explained in the digital input and digital output section of this manual, which include: I0. Once the MCR is re-energized by re-engaging the control power on the Remote Control Cabinet, after 15 seconds the grayed out setpoint will become active again; this is done to prevent an attempted writing of data to the temperature controller when it is not powered up. The primary responsibility of the PLC is to monitor and control the discharge system and associated components. 1 Pinnacle Lite Controls Manual explains the type of alarm, the ID code of the alarm and the cause of the alarm. After the setpoint and actual temperature are within the allowable range, automatically reset itself and after a short period of time (up to 15 seconds), you will see everything go back to normal. This digital input is only monitored if the machine is equipped with the auxiliary alarms feature and LLCs are installed. 7 Low Temperature Alarm During Start-Up After Shutdown. When the alarm first occurs, the highlighting will be red. 74 Infeed Grain Temperature High Limit Alarm The infeed grain temperature has exceeded the sensor temperature high limit setpoint. Low Temperature Alarm with the Burner Not Lit If the burner is not lit and the temperature controller experiences a low temperature condition, you will see a Type "A" alarm pop-up (warning only)
