Pinnacle 20|20 Controls
The fourth of the five options under Troubleshooting is PLC I/O Modules. The PLC and I/O modules are located in the Low Voltage Cabinet. The number of I/O modules depends on the model dryer. On the bottom of the page, only the I/O modules equipped on the dryer will be lit up, and therefore able to be accessed. The grayed out options cannot be accessed as those modules are not equipped on the dryer. Also, the order in which the PLC and I/O modules appear, should match the actual arrangement in which they are physically installed in the Low Voltage Cabinet.
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.
