Power the TC5-ITA then select MANUAL MODE using the func-
tion selection buttons.
•
Use the adjustment buttons to select the desired actuator status:
select
"OPEn"
to open,
"CLoS"

tor. The manual mode's status LED turns on when the actuator is
controlled manually.
VERIFY THE MOTOR'S OPERATION:
•
Manually open or close the air inlet panels as explained above. The
air inlet panels should open when the "

should close when the "
CLoS
" option is selected. If the air inlet
panels move the opposite way, the motor operates in the wrong

actuator's open and close terminals. Verify that the motor now oper-
ates in the right direction.
VERIFY LIMIT POSITIONS OF AIR INLET PANELS:
•
Select "
CLoS

If the opening of the air inlet is set as a percentage, the
controller may have to sligthly adjust the inlet opening val-
ues due to some internal restriction in the conversion pro-
cess.

Remaining Run Time / Opening Menu
If the inlet opening is displayed as a time value (internal switch #11 is OFF),
the REMAINING RUN TIME / OPENING menu shows a countdown of the
remaining moving time of the air inlet (opening or closing time). A negative
value is displayed when the inlet is closing. The letters "STOP" are dis-
played if the inlet is not moving.
If the inlet opening is displayed as a percentage, the REMAINING RUN
TIME / OPENING menu shows the current opening (in %) of the air inlet.
