One of the types of alarms that can occur are Cool Down alarms. When a Cool Down alarm occurs the dryer will enter Cool Down mode and the alarm popup will be orange as shown below:
After pushing the "X" in the upper right hand corner, the popup will disappear. When the dryer enters Cool Down mode, the fill, takeaway, metering /sweep and burners all stop . The fan(s) are the only components left running and they will continue run until the Cool Down timer expires.
The Cool Down timer can be seen from any HMI page, in the upper right hand corner, next to the Home button, while the dryer is in Cool Down mode.
Pressing the Cool Down timer button while the dryer is in Cool Down mode will cause the pop up below to appear, allowing the user the ability to cancel Cool Down mode or continue with it.
Selecting "No" means the dryer will continue the Cool Down mode until the timer expires. When the Cool Down timer expires, the fan(s) will automatically stop.
If "Yes" is selected, Cool Down mode will be cancelled causing the dryer fan(s) to continue to run.
Cancelling Cool Down mode means the dryer fan(s) will continue to run until commanded by the user, via the HMI, to do otherwise.
To acknowledge when the user selects "Yes", cancelling Cool Down mode, the following pop up will appear.
In addition to the pop up, a line item will appear in the Alarm History page, acknowledging when Cool Down mode has been cancelled.
Cool Down mode can be forced by simply pressing the Cool Down button on the Controls page. Doing so will shut down the burner(s), fill cycle and metering. Equipment associated with Takeaway 1 and 2 will begin their shutdown sequence after the takeaway timer, on the fan settings page, expires. The fan(s) will shut down as soon as the Cool down timer, also on the fan settings page, expires.
The third of the four options under Historical Data is Trending. By selecting Trending, the operator will be taken to a page containing Moisture and Mid-Grain trending graphs.
As previously mentioned, the trends displayed on the Monitor page are limited to 2-hour intervals. However, if the "More Trending Options" button located on the Monitor page is pressed, the operator is taken to this Trending page where the trends are displayed on a larger scale. Also, the Trending page allows for the two trending graphs to be displayed at 4 different time intervals. These time interval options are at the bottom of the Trending page and pressing them toggles the two graphs between 2-, 4-, 12- and 24-hour increments.
For convenience, the Mid-Grain Trending graph is directly below the Moisture Trending graph. These two graphs are in-line with each other, allowing the x-axis of both trends to be in sync. This makes it easy to read both the moistures and Mid-Grain temperatures at a given time since the time is plotted on the x-axis.
The last of the four options under Historical Data is Data Logging History. By selecting Data Logging History, the operator will be taken to a page listing all the data logged over the past six hours. The data is listed in reverse order with the most recent data at the top of the page. Each row of data contains the date, time, discharge speed, infeed moisture, discharge moisture, discharge moisture setpoint, mid-grain temperature and mid-grain temperature setpoint. The data listed is done so in ten minute increments.
As previously mentioned, the running data displayed on the Monitor page is limited to displaying the last 2 hours of data in 10 minute intervals. However, if the "More Data History" button located on the Monitor page is pressed, the operator is taken to this Data Logging History page where the data is still displayed in 10 minutes increments but spans a period of six hours.
Unlike the data shown on the Monitor page, this page only updates while the dryer is discharging. This allows the operator to see past running data even if the dryer has not been discharging for an extended period of time.
This section of the manual provides information on historical data of the Pinnacle 20|20 dryer control system.
The first of the four options under Historical Data is Alarm History. By selecting the Alarm History tile, the operator will be taken to a page listing all the active and past alarms. The top portion of the Alarm History page lists the Active alarms, and the bottom portion of the page lists the past, acknowledged alarms. Alarms that are still active are shown in yellow, orange or red depending on alarm type. Alarms that have been resolved appear in green. Each alarm has an ID, name, time and date of occurrence. The alarms listed in the Alarms History page are done so in reverse chronological order so that the most recent alarms will always appear at the top. Due to size restrictions, the Alarm History page is limited to approximately 22 past, acknowledged alarms.
When an alarm condition occurs, a popup will appear on the screen detailing the reason for the alarm and what type of alarm it is. These popups will appear on any active screen, on both HMI's. Press the "X" button to acknowledge the alarm and make the popup go away. The alarms are color coded to signify what type of alarm it is. Yellow popup alarms are warning alarms, orange pop up alarms are Cool Down alarms and red pop up alarms are critical alarms.
As mentioned, each alarm comes with it's own unique ID or Alarm numbers. The following pages list all the possible alarms, their ID's, name, and cause.
| ID | Name | Type | Cause |
|---|---|---|---|
| ID | Name | Type | Cause |
|---|---|---|---|
| ID | Name | Type | Cause |
|---|---|---|---|
| ID | Name | Type | Cause |
