Appendix A: Troubleshooting

During setup and use of the Digital Dosing Additive Feeder, personnel may experience

difficulties. Some of the problems encountered may be resolved using the following

techniques.

A.1 General Troubleshooting - Unit Will Not Operate

• Check all connections and process wiring. Note that the process machine input MUST

be wired to a DRY contact for Injection Molding (Section 2.8.1) and Extruder Constant

Applications (Section 2.8.2). For Extrusion Proportional Application see Section 2.8.3.

• Ensure the correct Configuration Codes have been entered to configure the Digital

Dosing unit for the process and installation, see Section A.4.

A.2 Malfu nctions or Error s - Error Codes

When a malfunction or error occurs, the controller displays the Alarm symbol and an error

code. The code consists of an “A,” followed by an error number. The control unit will not

operate until the malfunction or error has been corrected. To acknowledge and clear the alarm,

press the Stop key ( ). Once the malfunction is corrected, press to begin dosing

operations.

NOTE: Stop will not correct a malfunction or error.

Following is a table with the error codes, possible reasons for

each code, and solutions to the problems presented.
