Resetting the Drive from the Control Panel

When the red LED of the ACS-PAN is on or blinking, a fault is active.
To reset a fault when the red LED is on, press the RESET button.
Caution! This may start the drive, when in remote control.
To reset a fault when the red LED is blinking, turn the power off.
Caution! Turning the power on again may start the drive immediately.
The relevant fault code (see Diagnostics) flashes in the panel display until the fault is reset or the
display is "cleared".
You can "clear" the display without resetting the fault by pressing any button.
Note! If no other button is pressed within 15 seconds and the fault is still active, the fault code
will be displayed again.
After a power failure, the drive will revert to the same control mode (LOC or REM) as before the
power failure.
