IMPORTANT REMARKS

For any installation problem please contact our Customer
Service.
KEY Automation has the right to modify the product without
previous notice; it also declines any responsibility to damage
or injury to people or things caused by improper use or wrong
installation.
Please read this instruction manual very carefully before
installing and programming your 900CT-380 control unit.
• This instruction manual is only for qualified technicians,
who specialize in installations and automations.
• The contents of this instruction manual do not concern the
end user.
• Every programming and/or every maintenance service
should be done only by qualified technicians.
AUTOMATION MUST BE IMPLEMENTED IN COMPLIANCE
WITH THE EUROPEAN REGULATIONS IN FORCE:
EN 60204-1 (Machinery safety. electrical equipment of
machines, part 1: general rules)
EN 12445 (Safe use of automated locking devices,
test methods)
EN 12453 (Safe use of automated locking devices,
requirements)
• The installer must provide for a device (es. magnetotermical
switch) ensuring the omnipolar sectioning of the equipment
from the power supply.
The standards require a separation of the contacts
of at least 3 mm in each pole (EN 60335-1).
• After making connections on the terminal board, use one
hose clamp to fix dangerous voltage wires near the terminal
board and another hose clamp to fix safety low voltage wires
used for accessories connection; this way, in case of
accidental detachment of a conducting wire, dangerous
voltage parts will not come into contact with safety low
voltage ones.
• The plastic case has an IP55 insulation; to connect flexible
or rigid pipes, use pipefittings having the same insulation
level.
• Installation requires mechanical and electrical skills,
therefore it shall be carried out by qualified personnel only,
who can issue the Compliance Certificate concerning the
whole installation (EEC Machine Directive 89/392, Annex IIA).
• The automated vehicular gates shall comply with the
following rules: EN 12453, EN 12445, EN 12978 as well
as any local rule in force.
• Also the automation upstream electric system shall comply
with the laws and rules in force and be carried out
workmanlike.
• The gate thrust force adjustment shall be measured
by means of a proper tool and adjusted according to
the max. limits, which EN 12453 allows.
• We recommend to make use of an emergency
button, to be installed by the automation (connected
to the control unit STOP input) so that the gate may
be immediately stopped in case of danger.
• Always remember to connect the earth according to
current standards EN 60335-1, EN 60204-1 (the 900CT-380
control unit has two specific W4 and W5 clamps).
• Do not install the device outside!

DESCRIZIONE DELLA CENTRALE

The control unit 900CT-380 is an innovative KEY product that
guarantees a safe and reliable automation of industrial sliding
gates and multi-section doors.
The 900CT-380 has been designed to realize a product that
meets all kind of requirements, with a highly versatile control
unit that satisfies all the necessary requirements for a
functional and efficient installation.
900CT-380 is provided with a display that, not only makes
programming simple, but also allows a continuous monitoring
of the input statuses; in addition, thanks to a menu structure,
the working schedule and the operation logic can be set easily.
In compliance with the European standards concerning
electrical safety and electromagnetic compatibility
(EN 60335-1, EN 50081-1 and EN 50082-1) it has been
equipped with the low voltage circuit total electric insulation
(motors included) from the network voltage.
Other characteristics:
• Detecting obstacles by monitoring the power absorbed by
the motors.
• Automatic learning of the operation time.
• Tests for safety devices (photocells, ribbons and triacs)
before each opening.
• Deactivation of safety inputs through the configuration
menu: no jumper is required for terminals concerning safety
devices that have not been installed, yet. You will only need
to disable this function from its relevant menu.
• Brake function.
• Possibility of piloting 400V three phase, 230V three phase
and 230V single phase motors.
