7. Extended Setup Screen
The following list can be modified here:
1. Diagnostics:
Figure 5N
Check Light Outputs: Allow the user to verify the controller is attempting to illuminate each
individual switch. If there is a check mark present on the Vision screen, the corresponding
switch should be lit. If not, there is a wiring issue.
Check Switch Wiring: Allows user to verify the controller is recognizing switch positions
correctly. If the “Fan 1” switch is in the “AUTO” position, the “FAN 1 AUTO” box should be
checked. If not, there is a wiring issue.
Set MR Speed Via Screen: Normally, the meter roll adjustment knob on the control panel
is used to set the metering roll setpoint. In the event of a knob malfunction, the metering roll
setpoint can be adjusted by this screen.
Calibrate Moisture Sensors: Previously mentioned in the preceding “Setup Screen”
section
on Page 25 . This is just another way to access those settings.
2. Differential: The button will display the “Modifying Burner Differential Settings”
screen. (See Figure 5O on Page 30.) Adjusting the burner differential settings allows the
operator to keep the plenum temperature within a certain range.
NOTE: 1° is the default and preferred setting.
