System Alarms

System Advisory/Record Codes

TABLE 3 lists the advisory and record codes. Advisories and records do not stop operation or sound an alarm. If an advisory occurs, the Status bar on the Display Mod- ule shows the advisory icon and code. System records do not display on the Status bar. Both advisories and records are saved in the date/time stamped log, which can be viewed on the display or saved to a flash drive using optional USB port.

To reset alarms, see Table 3, and Alarm Troubleshoot- ing, page 53. Many errors can be cleared by simply

Air Flow Switch (AFS) Function

Air or Air-assisted Guns

The air flow switch (AFS) detects air flow to the gun and signals the ProMix 2KE controller when the gun is trig- gered. The gun icon on the Display Module shows spray when the AFS is activated.

If a pump fails, pure resin or catalyst could spray indefi- nitely if the ProMix 2KE does not detect the condition and intervene, which is why the AFS is so important.

If the ProMix 2KE detects through the AFS signal that the gun is triggered, yet one or both of the pumps are not running, a Dose Time Alarm (QTA1 or QTB1) occurs after 40 seconds and the system goes into Standby.

NOTE: Systems with a 45:1 pump ratio are designed for use with an airless gun. These systems contain no air flow switch and are set up so that they do not trigger a System Idle Warning.

NOTE: For airless applications with other pump ratios, the air flow switch can be disabled on Configure 2 (Screen 19).
