Troubleshooting
Introduction This chapter describes the Digital Reference Adapter Board fault
diagnostics and how they are processed by the 1395 Drive.
Proper sequencing of the logic and control modes may be verified by
monitoring Parameters 596, 597 and 598 with the DHT or ITS.
It should be noted that improper operation of the Belt Drive System
may often be caused by problems external to the 1395 Drive System.
Always check that the proper logic commands are being received
from the Paster Panel per the Logic State Diagram. Also, check that
press and belt speed frequency signals are being received from the
Paster Panel. Table 1 is provided as a quick reference of the
Parameters that may be used to check incoming logic commands,
speed signals and dancer operation.
All adapters provide initial fault handling based on conditions within
their environment, and then signal the 1395 which provides further
disposition based on system requirements. Faults are divided into
three categories as described below.
