Rotary Knob Troubleshooting
If rotating the knob on the keypad panel does not change the selected data
field value, the signal from the knob is not being received by the iControl
PC. If this happens, check the wiring connections from the keypad panel to
the iControl PC. If the connections are good, replace the keypad panel.
WARNING: Do not spray powder with the iControl console door open
unless the console opening, the door, and all externally connected devices
are out of the hazardous area surrounding any opening of the spray booth.
The hazardous area extends 3 feet outward from an opening and continues
in a 3 foot arc from the edge of an opening. Failure to observe this warning
could create a hazardous condition and could result in personal injury or
property damage.
Temporary Fix: Perform a program shutdown and turn off console power.
Connect a standard PC keyboard with a PS2 connector to the KEYBOARD
port on the left side of the iControl PC. Turn on power and use the numeric
keys to enter values in selected data fields, or use the up and down arrow
keys to change field values. Replace the keypad as soon as possible.
