The TROUBLESHOOTING section explains how to clear an
alarm, and provides diagnostic tables to help you determine
the cause of the alarm.
Diagnostic tables have been divided into:
r Conveying System Alarms.
These tables focus on the “No Material” and “Pump
Overload” alarms that the B32 displays on the Alarm
Summary screen. The B32 continues to control the system and
the alarming loading station will load.
r Power and Processor Problems.
These tables focus on power supply and processor problems
indicated by Micrologix 1500 LEDs located inside the I/0
enclosure. These problems cause the B32 control to stop.
r CPU Faults.
These tables focus on Hex error codes that apply to the
Micrologix 1500 and are displayed as faults on the Rack &
Slot screen. These problems cause the B32 control to stop.
