Confirm Automatic Operation
To put your ATS into Auto mode, confirm the slide switch is in “AUTO” before the enclosure door is
closed. This slide switch overrides the Auto/Manual mode set from the HMI. To place ATS controller in
auto mode, press the auto key on the HMI as in Figure 7. If already in Auto mode, pressing this key will
take the switch out of Auto mode.
Confirm the ATS is in Auto mode by validating that the “AUTO” LED above and to the right of the LCD
screen is solid green.
