How to Identify the Cause of a
Problem
Dryer alarms are indicated by an illuminated Acknowledge Alarm light on the
Carousel Plus W Series Dryer control panel. Shutdown alarms will sound the
alarm horn and turn on the alarm beacon.
A problem can trigger two types of alarms:
• Shutdown: The dryer has automatically shut down because it has detected a
serious problem that could damage your material or dryer.
• Passive: The dryer continues to operate, but warns of a problem that could
prevent correct drying of your material. If ignored, this problem could lead to
a condition that will shut down the dryer.
When the alarm light is displayed:
1 Press the Acknowledge Alarm button once to silence the
optional audible alarm and display the alarm message. Pressing the
Acknowledge Alarm button once also changes the alarm LED from blinking to
solid.
2 Find the error message in the diagnostics table of this Troubleshooting
section. Use the information in the table to resolve the cause of the alarm.
3 Note that pressing the Acknowledge Alarm button a second time will clear
the alarm. If at alarm reappears, the cause of the alarm has not been resolved.
NOTE: When the dryer detects abnormally high temperature in the process heater, the
dryer immediately shuts down and an error message appears in the display window.
