AFS AND FAN INTERLOCK
The operation of the Air Flow Switch (AFS) and Fan Interlock (FIR) are checked here.
Start the moist air fan and make sure the air volume is adjusted for the application. The
water spray chamber door should be closed and gate valves set before making any
adjustments. Both lights should be green. If the Air Flow Switch light is red, the range
settings for the air flow may need to be adjusted.
To adjust the air flow range settings, touch the page back button ( <
-
) to go back to the
Test Program screen, then touch the <
-
button to go back to the SETUP screen. Now
press ANALOG SETTINGS button and then ANALOG AIR FLOW SWITCH button.
This will take you to the screen shown below.
Take the Air Flow (V.P.) reading and multiply this number by 0.7. This is the MIN V.P.
setting. For example using the screen below, 0.37 X 0.7 = 0.26. Set MIN V.P. to 0.26.
Example:
0.37 X 0.70 = 0.26
