2 chirps per second "Supervised" means the STC must see the photo-eye NC con-
once per minute tact change from closed to open and back to close after receiv-
ing the command to move, but before starting. (FAL2 indicates
the Smart Touch did not see this sequence at start.) Be sure the
photo-eye is capable of, and set to provide this function. Be
sure the eye "common" wire is wired properly to the "Photo
Eye Power 24V Common" Terminal and Installer Menu Item 18
(PEO/PEC-NO/NC) is set to 1.
2 chirps per second The 24V control voltage is monitored in lieu of line voltage. Low
once per minute incoming line voltage will cause low control voltage. Verify that
the control transformer is connected properly, (white – not used,
red for 208V, orange for 230V and blue for 460V). Check the
line voltage as the motor starts with a meter that has min/max
hold capability. If the line voltage drops more than 10% below
nominal (187 on 208VAC, 207 on 230VAC, or 416 on 460VAC) the
voltage is dropping too low and must be corrected. This condi-
tion is often caused by loose connections or power wiring which
is too small. If the wire is too small, it must be replaced. See
page X for proper wire size.

3 chirps per second Try turning off the power to the operator and having the cus-
once per minute tomer re-seat all of the various connectors and cables. If the fail
does not go away, REPLACE the STC board.
