Alarms
When a T5 ATG is in alarm, the Alarm LED on the front of the ATG will flash. If the line has
been programmed to shut down the pump on failed test (in the FMS Setup), the pump will be
unavailable for all system tests and dispensing until the line with the active alarm is manually
reset. If the condition still exists after reset, the alarm will return. A service visit may be required
to identify and correct the condition.
WARNING
: Turn off power to the ATG before you install or remove a module or perform any
maintenance procedure while the ATG door is open.
IMPORTANT
: Read the "Operating precautions" in the "Introduction" chapter before you perform
any maintenance on the ATG.
NOTE:
If this guide is not able to help you correct a warning or alarm, please contact FFS
Technical Support at 1.800.984.6266.
