CPU
The first option at the bottom of the page is the CPU and is on all Pinnacle 20|20 dryers. The CPU allows up to 14 digital inputs, 10 digital outputs, 2 analog inputs and 2 analog outputs.
14 Digital Inputs
| I/O | Name | Description |
|---|---|---|
Ia.0 | Safety Control Relay | When shown in green, the Safety Control Relay is satisfied. |
Ia.1 | Fan Motor Overload(s) Fault | When shown in green, there are no Fan Motor Overload Faults present. |
Ia.2 | Takeaway Equipment Status | When shown in green, Takeaway Equipment Status is ready to be started. |
Ia.3 | Fill Equipment Status | When shown in green, Fill Equipment Status is ready to be started. |
Ia.4 | Fill Level Signal | When shown in green, there is currently a call for grain. |
Ia.5 | Proximity Switch | When this blinks green, the proximity switch is sensing the metering target. |
Ia.6 | E-Stop(s) | When this shows green, all dryer E-Stops are reset. If shown in white, 1 or more dryer E-Stops are depressed and need to be reset. |
Ia.7 | Customer E-Stop (C5 & C6) | When this shows green, all E-Stops associated with auxiliary equipment are reset. If shown in white, 1 or more E-Stops associated with auxiliary equipment are depressed and need to be reset. |
Ib.0 | Takeaway Overflow | When shown in green, the takeaway switch does not sense grain backup. If shown in white, grain is causing a backup that the switch detected and the situation should be addressed. |
Ib.1 | Linear Limits Fault | When shown in green, there are no excessively high temperatures being detected by the Linear Limits. When shown in white, the Linear Limits sense an excessive temperature condition that needs to be addressed. |
Ib.2 | Plenum Door(s) | When shown in green, the plenum door switches detect the plenum doors are closed. When shown in white, 1 or more plenum doors are open. |
Ib.3 | High Gas Pressure Fault | When shown in green, there is no high gas pressure situation being detected. If shown in white, a high gas pressure situation is being detected. |
Ib.4 | Low Gas Pressure Fault | When shown in green, there is no low gas pressure situation being detected. If shown in white, a low gas pressure situation is being detected. |
Ib.5 | Auxiliary Contactors | Green indicates that the start contactors A and B are turned ON. White means they are OFF. |
