SAFETY RIBBONS

The control unit 900CT-101 is equipped with a specially
provided input to control safety ribbons; the intervention of the
safety ribbons reverses the motion for 3 seconds - it can be
enabled only during opening phase, only during closing phase
or always.
This input can control either the classic edge with N.C. contact,
or the conductive rubber ones with nominal resistance 8,2
kohm.
Connect the cables of the safety ribbons between terminals K4
and K5 of the control unit.
WARNING:
• When using more ribbons with N.C. contact, the inputs have
to be series connected.
• If using more conductive rubbers, the outputs have to be
cascade connected and only the last one has to be
terminated on the nominal resistance.

END OF STROKE

The ends of stroke are already connected by means of the
special connector shown in the picture.
If the ends of stroke work in the opposite way, reverse the
connector.

STOP

For a better safety, you can fit a stop switch that will cause the
immediate gate stop when activated. This switch must have a
normally close contact that will get open in case of operation.
In case the stop switch is operated while the gate is open, the
automatic closing function will always be disabled. To close the
gate again, you will need a start command (if the start function
in pause is disabled, it will be temporarily enabled to allow the
gate release).
Connect the stop switch cables between terminal K3 and K4 of
the control unit.
The stop switch function can be activated by means of a
remote control stored on channel 3 (see relevant instructions
of 900RXI-44 receiver).
ACTIVATION INPUTS
900CT-101 control unit is equipped with two activation inputs,
whose operation depends on the programmed operation modes
(see Strt item of programming menu):
• Standard mode: a command being on the first input will
cause the complete opening of both leaves (start); a
command being on the second input will cause the partial
opening of leaf 1 only (pedestrian start).
• Open/Close command and manned operation: a command
on the first input always controls the gate opening, while a
command on the second input always controls the gate
closing.
In Open/Close mode, there is an impulse command, that is
to say that an impulse will cause the complete gate opening
or closing.
In manned operation, there is a monostable command, that
is to say, the gate will be opened or closed as long as the
contact is closed and it will immediately stop as the contact
is open.
• Timer mode: it is similar to the standard mode but the gate
stays open (completely or partially) while the contact is
closed on input; as soon as the contact is open the pause
time count down will start, after which the gate will be
closed again. This function allows programming the gate
opening time during the day, by making use of an external
timer. Automatic closing must be enabled.
In all modes, inputs must be connected to devices having
normally open contacts.
Connect cables of device controlling the first input between
terminals K1 and K4 of the control unit.
Connect cables of device controlling the second input between
terminals K2 and K4 of the control unit.
The first input function can also be activated by pressing UP
key outside the programming menu or by means of a remote
control stored on channel 1 (see relevant instructions of
900RXI-44 receiver).
The second input function can also be activated by pressing
DOWN key outside the programming menu or by means of a
remote control stored on channel 2.
