ADJUSTING THE ELECTRONIC (SPEED 2), ELECTRICAL (SPEED 5 - SPEED 8) CLUTCH
SPEED 2 adjustment was pre-set when the card was programmed however it can be set (see the MEC 1000 or K122M instructions).
SPEEDS 5 and 8 can be adjusted by acting on the control card (see the K550M instructions).
ELCTRIC CONNECTIONS
Before starting work, make sure that the gear motor is not connected to the power supply.
To make connections, remove the safety guard of the gear motor, thread the power cables through the holes in the foundation counterplate
(when this is used) and through the lower body of the gear motor, then prepare them for connection to the terminal board of the control card
housed in the electrical components support.
The distance between the control unit and the motor must not exceed 10 - 12 m.
Use cables with a minimum section of 2.5 mm² for the power circuits (SPEED 2), 1.5 mm² for SPEEDS 5 and 8, and 0.5mm² for the control
circuits.
For connections to the control cards, consult the relative instructions handbooks:
-
MEC1000 or K122M for SPEED 2;
-
K5500M for SPEED 8.
INSTALLING A 12V BATTERY (ONLY FOR SPEED 2)
If you want to give your geared motor a battery to ensure it will continue working even in a blockout, remove the casing, put it in place and
connect the power cables to the tabs.
MANUAL RELEASE
In the event of a power failure, remove the cover of the lock, fi t the relative key and turn it as shown in fi g. 24.
Then, as shown in fi g. 25, lift the lever towards the outside to move the gate manually.
ELECTROMECHANICAL LIMIT SWITCH
SPEEDS 5 and 8 have been designed to work with a micro-switch controlled electromechanical travel stop.
The wires are connected as shown in Fig. 28:
1 = grey - common;
2 = grey - common;
3 = orange - FC close - NC contact;
4 = red – Limit Switch open - NC contact.
If movement continues when the gear turns clockwise and the spring moves, as shown in fi g. 29, invert the position of the wires (red and
orange) on the terminal board of the control board.
OPTIONAL ACCESSORIES
The door can also be powered as indicated in fi gs. 30-31 which also show installation distances.
Fig. 32 shows the type of chain required (thread 1/2" x 5/16"); fi gs. 33-34-35 show the subsequent phases for fi xing the chainstretchers.
GENERAL ADVICE
-
Install a gate safety system that complies with current regulation.
-
Choose short routes for cables and keep power cables separate from control ones.
-
Earth the geared motor properly.
-
Please refer to current regulations when setting the geared motor's maximum torque.
-
We advise you to install an outdoor switch, in compliance with European standards on the issue of safety, turn the electricity off when
servicing the gate.
-
Check that each single device installed is effi cient and effective.
-
Affi x easily readable signs, warning about the presence of a motorized gate.
USE
SPEED 2, 5 and 8 geared motors have been designed to move horizontally sliding gates with leaves weighing max. 400Kg (for SPEED 2),
500kg. (for SPEED 5) and 800Kg (for SPEED 8).
It is absolutely forbidden to use the device for any other purposes or under circumstances different from those mentioned.
The electronic unit installed (which must have a built in electric friction) normally permits you to select the following functions:
automatic: a command pulse will open and shut the gate;
semi-automatic: a command pulse will open or shut the gate;
In the event of a power failure, the gate may be moved manually by activating the "manual release" device. Mod. SPEED 2 can be powered
by a buffer battery and is able to perform at least 15 complete cycles (open and close) on its own.
This is an electrically powered automatic device and should therefore be used with care. In particular:
•
do not touch with wet hands and/or wet or bare feet;
•
disconnect the power supply before opening the control box and/or the gearmotor;
•
do not pull the plug out by its cable;
•
do not touch the motor unless you are certain it is cool;
•
only operate the gate when it is completely visible;
•
do not approach the gate while it is moving;
•
do not allow children or animals to play near the gate;
