Electrical Connections - Key Automation 900CT-101 Manuel D'emploi

VISUAL DIAGNOSIS
The control unit is designed to automate residential and industrial openings with 1 motor having a maximum
power of 1,200W ea. with active and passive safety controls for installation that is compliant with current
safety standards.
•
STOP input no. 11 in which the use of a contact N.C. is compulsory must be closed and the two
points of the LCD must not flash. If they flash, it means that the contact is open
•
The input PHOTO OPEN F2 no. 10, which requires the use of an NC contact, must be closed and
the F2OP point of the LCD on the left must be OFF. If it is on STEADY it means that the contact is
open
•
The input PHOTO OPEN F1 no. 9, which requires the use of an NC contact, must be closed and the
F1CL point of the LCD on the right must be OFF. If it is on STEADY it means that the contact is open
N.B. In normal use, the points of the LCD must not flash or be on steady. They flash or stay on if the
corresponding safety is activated.

ELECTRICAL CONNECTIONS

To ensure operator safety and to prevent damage to the components while connections are being made, or
when the radio card is being inserted, the control unit absolutely must not be powered on.
For power cords, motor lines, flasher/courtesy light line, and electric lock, use a cable with a cross-section
that is suitable for the length (minimum 1.5 mm
For auxiliary power supplies, controls and safety contacts a minimum section of 0.5 mm
cables are very long (more than 30 m), de-coupling is suggested using relays at the control unit.
If a fuse trips, after removing the cause, replace it with another one of the same type. Install the various
safety devices, limit switches, photocells, sensitive rib, stop button.
If one or more of the safety devices are not installed, the corresponding terminals must be short circuited
with the controls common.
All contacts N.C. Assigned to the same input must be connected in series.
All contacts N.O. Assigned to the same input must be connected in parallel.
Provide disconnecting devices in the power supply network in accessible places.
For the power supply of the control unit, there must be an external disconnecting switch (not included),
independent and properly sized.
- CN1 is dedicated to the connection of the power supply of the board:
N.1 and N.2 230V AC
N.3 is connected to the courtesy light
N.5 is connected to the flasher
N.4 shared courtesy light or flasher max.25w 230Vac
N.6 is connected to the earth of the system
- Connection of Motor : Term.N.19 opening, N.20. closing and N.21 shared
- Motor limit switch connection between N.24(limit switch opening) N.22(limit switch closing)
- Motors limit switch common connection N.23
N.B. The LEDs that correspond to the limit switches are ON when the relative limit switch is not involved,
if you do not use the limit switch they must be jumper connected to the COMF terminal
N.23
- PED pedestrian function: Connected between Term. N.7 and Term. N.12 Contact N.O. Normally open
It is an opening command which when activated will partially open the door (50%)
- Step/step operation:
Connected between Term. N.8 and Term. N.12 Contact N.O.
Control input open/close or open/stop/close based on selection of parameter D
- Photocell Close Function F1 :
Connected between Term. N.9 and Term. N.12 Contact N.C.Normally Closed
This input is considered a safety, the contact can be interrupted at any time during closing of the
automation causing an immediate stop in movement and reversing the direction of movement
