Electrical Connections - electrovolta 900CT-380 Manual De Instrucciones

The control unit was designed for the automation of industrial openings with 1 motor with tri-phase power
supply 380V. or single phase 230V. with maximum power of 2,000 W with active and passive safety controls
to obtain installation that is compliant with current safety standards.
Thanks to the patented PFC Control system in the models 900CT-380/1, programmable deceleration is
performed to stop at the limit switches. This provides fluid and uniform control of all the movement of the
door, limiting inertial forces on especially large and heavy gates
VISUAL DIAGNOSIS OF STATUS OF SAFETIES
STOP input no. 18 in which the use of an N.C. contact 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 F.OP no. 17, 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 CLOSE F.CL no. 16, 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 mm2).
For auxiliary power supplies, controls and safety contacts a minimum section of 0.5 mm2. When the control
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:
with tri-phase power supply 400V AC use RST
with single-phase power supply 230V AC connect F N
- Connection of motor: Term. N.4 opening, N.6 closure and N.5 common
- Motor limit switch connection: N.11 (limit switch opening) N.13 (limit switch closure)
- Motors limit switch common connection N.12
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.12
- PED pedestrian function: Connected between Term. N.14 and Term. N.19 Contact N.O. Normally open
It is an opening command which when activated will partially open the door (50% of total travel)
- Step/step operation:
Connected between Term. N.15 and Term. N.19 Contact N.O.
Control input open/close or open/stop/close based on selection of parameter D
- Close Photocell Function F.CH :
Connected between Term. N.16 and Term. N.19 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
