NOTE: An internal memory check is done on each power up. So if a corrupted
memory is detected, a factory reset will be done automatically.
WARNING: On standard jobs, the factory reset will return the settings
and features to a generic default. The actual settings and values for
the specific job must now be entered to customize the job for the
particular application. To determine if a particular controller has a
standard program, go to the banner screen. If the value in the lower
left of the screen is the Virginia Controls Job Number, then the chip is
specific for that job, and a factory reset will load the values for that
job. If the value is not the job number, (it will start with a letter)
then the program is a standard, and the actual values for the job need
to be entered. These values are provided with the controller in the
schematic, and are based on the requirements of the job, as conveyed
to Virginia Controls.
A factory reset can also be done without the keypad as follows:
1.
Turn off the power
2.
Turn the Inspection Switch to "Inspection" (or remove the field wire from terminal
23)
3.
Jump terminals 1 to 21 and 22 (Up and Down Level Switch Inputs)
4.
Turn the power back on for 10 seconds. Inputs 1 and 2 on Board 1 should both be
ON, and Input 3 on Board 1 should be OFF.
5.
Turn off the power
6.
Remove all jumpers and put the car back on normal operation.
