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. 

 

•  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. 

 

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. 

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

each code, and solutions to the problems presented.
