Message or Condition Cause/Correction
Message: Too many (few) control
nodes found
The number of gun cards/iFlow modules does not match the
number of guns setting in Guns Configuration screen (System
Configuration). This could be a normal condition if you have an odd
number of guns in your system. The red Fault LED on the gun card
will light if two guns are not connected to the card.
Message: Failure reading
database
No data or configuration displays on screens. User data card
missing, defective, or wrong size. Replace the card.
Compact Flash adapter failure. Replace the adapter.
Condition: iControl screen partially
boots up. Screen is blank except
for possible text display, or screen
displays “Hit ESC for .altboot...”
Program card is missing, blank, or defective. Replace the card.

Condition: Pickoff value is reset to
smaller number after entry
The maximum pickoff length is 4096 inches (104038.4 mm). With
the keypad you can enter a number larger than the maximum, but
when you save your entry the value will be automatically reduced to
the maximum value.
Condition: Inconsistent lead and
lag timing for auto gun triggering or
moving
Conveyor encoder pulse rate is too fast. Maximum is 10 Hz (10
pulses/second). Some pulses are not being detected. Reduce the
conveyor speed or change the encoder-to-conveyor linkage to
reduce the pulse frequency.
Condition: Lockout message does
not display when keyswitch turned
to lockout position, or lockout
cannot be canceled by turning
keyswitch to another position
Booth exhaust fan is off (turning off switched power to the console),
or remote lockout is on.
If the exhaust fan is turned off before turning the switch to Lockout,
then lockout cannot be activated. If the fan is turned off after the
switch is turned to Lockout, then lockout cannot be canceled. Turn
fan on to correct.
If the remote lockout is on, turn it off. Remote lockout is activated
by a customer-supplied switching device connected to the remote
lockout relay in the console.
Condition: iControl screen is
locked up (no response)
Cycle console power. If the condition persists, the program card is
corrupted. Obtain and install another program card. Refer to Touch
Screen Calibration when installing new program cards.

triggered on
iFlow module requires re-zeroing. Re-zero the iFlow module as
described on page 4-12.
