4. Press Ent to reset all settings to the factory defaults.
5. Press Esc to return the controller to normal operation.
NOTE: If the program is a standard program, then the settings for the specific
job must be re-entered.
Q. How do I determine if I have a standard program?
1. Go to the Banner screen, by pressing Esc until the top line of the display shows
“VA.CONTROLS” at the left.
2. If the text on the lower left is the job number, then the program is NOT standard. It has
been set up for the particular job.
3. If the text on the lower left starts with letters “D” or “E” (such as “DAS” “DDS” “DES”
“DSS” “ES” “ED”) then the program is standard. If a factory reset is performed, the
standard default values will be loaded. Check the schematic for the particular values for
your installation, and change the values as required. Usually the values that are custom
for a particular job are shown in BOLD, so these values must be changed, but the other
values should be checked.
Q. How do I check the current values of the settings
and features?
1. Go to the Setup Menu.
2. Select the menu item "Change Settings", and press Ent, then enter the password,
“911”.
3. Scroll through the settings by pressing Nxt. The settings will not be changed unless a
new value is entered and then Ent is pressed.
4. Press Esc then Nxt to go to the "Change Features" menu item.
5. Press Ent, then enter the password, and press Ent.
6. Press Nxt to scroll through the features. The features will not be changed unless you
press Aux then Ent.
7. Press Esc twice to return to normal operation (Run Mode).
Q. Why is the LCD Display blank?
The LCD Display goes blank after the CPU resets if S2 switch 1 is in the OFF position.
This will happen when the power to the CPU is cycled, or when the Reset Button on the CPU
board is pressed.
Press any key to activate the screen.
If the screen does not activate, the problem could be with the Keypad (momentarily
touch pins 1 (far left) and 8 (far right) on the top of the keypad connector to simulate
pushing a key) or the CPU (check that LED D5 is flashing), or the LCD Display.
