The EN1000 controls are shipped with the automatic voltage compensation feature disabled.
Under conditions of poor line voltage regulation, its use will provide consistently good
quality welds in spite of varying line voltage. To enable the AVC, the EXTENDED
FUNCTION [CC] Mode must be selected. See section 7.3 EXTENDED FUNCTIONS. Use
the SCHEDULE SELECT Push Buttons (20 & 21) and SCHEDULE Display (22) to select
[CC]. With the control in the PROGRAM Mode, enter a code number to enable AVC (00
to disable) into the DATA Display (4) using Data Push Buttons (5 & 6). Depress the ENTER
Push Button (29) to load the desired Data.

Note 1: The AVC must be enabled at a time when the line voltage is nominal, not
abnormally high or low.
Note 2: Also, when using AVC, select a percent current not higher than 85% to allow the
AVC circuit "operating space".

It is sometimes desirable to clear all previous schedules and EXTENDED FUNCTIONS
from the memory and return the programmed control parameters to factory defaults.
To program the control for the CLEAR ALL function, the EXTENDED FUNCTION [CA]
mode must be selected. See section 7.3 EXTENDED FUNCTIONS. Use the SCHEDULE
SELECT Push Buttons (20 & 21) and SCHEDULE Display (22) to select [CA]. With the
control in the PROGRAM Mode enter the required value from the table below into the
DATA Display (4) using DATA Push Buttons (5 & 6). As typical of other data entry the
ENTER Push Button (29) must be depressed to load the desired data.
