Setting the Process Air Temperature
When setting the process air temperature, consult with the resin manufacture for the recommended drying temperature.
To change the process air temperature set point with the dryer running:
•Press to raise the set point to the temperature you want.
•Press to lower the set point to the temperature you want.
Restoring the Process Air Temperature Controller (E5CN) to Factory Settings
If the preset parameters on the controller have been tampered with and it no longer properly controls temperature, you can restore the controllers to the factory setup. Call the Service
Department for detailed instructions.
E5CN Operating Parameters
The E5CN controller has several mode selections. Within each mode are numerous parameters that can be set.
The factory has set the security level to protect the critical parameters from being accidentally changed. Below is an explanation of the operating modes you will have access to and on the following page are the manufacturers’ default settings.
Available E5CN Modes

| | Alarm Value 1 | This setting is used to indicate how many degrees |
| | Mode (AL-1) | the process temperature will be allowed to exceed |
| | (35°F) | the set point temperature. An alarm output will de- |
