ALARMS
Display Battery Low
This alarm indicates that the User Interface’s lithium
battery is low and it could lose its memory if the prob-
lem is not corrected.
Do not
power down the system if
this alarm occurs. Follow the instructions for changing
the battery on page 11–3.
Control Battery Low
This alarm indicates that the Controller’s lithium battery
is low and the Controller could lose its memory if the
problem is not corrected.
Do not
power down the
system if this alarm occurs. Follow the instructions for
changing the battery on page 11–4.
Memory Failure
This alarm indicates that memory has been lost in the
system. If memory is lost, all recipe and configuration
data are gone and factory default settings are
reloaded. Memory failure is most likely caused by a
low or faulty Controller battery. Follow the instructions
for changing the battery on page 11–4. Restore the
memory with the PrecisionMix II Maintenance Utilities
software, provided with the system.
Communications Error
A communications error occurs when the User Inter-
face is not communicating with the Controller. This is
usually due to a loose wire or a poor connection at the
back of the User Interface. If a communications error
occurs, check for loose wires or a loose cable. If that
does not correct the problem, turn the power to the
system off and than back on again to re-initialize
communications.
Invalid Guns From Input/Output Alarm
The selection of spray guns that idle on active gun
prior to purge activate alarm. Guns can be added at
any time while spraying by selecting both guns from
gun #1 and gun #2 selection but changing from gun #1
to gun #2 or both to gun#1 and gun #2 will generate
this alarm.
Air Flow Switch Alarm
This alarm is associated with the gun flush boxes
option only. The alarm is generated when the system
is in the purge mode and the air flow switch signal is
active preventing atomization of the solvent.
Defaults Loaded
This alarm is generated when all the factory default
configuration and recipe values are loaded. This alarm
will always be active when the system is shipped from
Graco.
Software Revision Alarm

ware revision is different than the Precision Mix II
controller software revision. If this alarm is generated,
finish upgrading the software using the utility kit.
