Common Messages and Meanings from K-Cdr Introduction This section will present some common messages as displayed by the K-Commander (K-Cdr) and provide an explanation and resolution to them. Alarm specific messages are found in the Alarm page 03. Common The following table outlines common K-Cdr messages.
This section deals with the pages that the operator will likely program. Please note that the page numbers beginning with 01 is merely to give reality to the display and this number could range from 01 to 15. Produced by the K-Tron Institute Rev: G...
