6 TESTING
Perform the following sequence of operations to test the LIMIT barrier system:
• Check that all the prescriptions in this manual have been followed
scrupulously, with special attention to chapter 1 "General Prescriptions";
• Using the supplied control or stopping devices (key selector switch,
control pushbuttons or remotes), perform opening, closing and stopping
tests and make sure the barrier responds correctly to the various
commands.
• Check operation of all the system's safety devices (photocells, safety
edges, emergency stop, etc.), one by one.
7 PRODUCT MAINTENANCE
Maintenance must be carried out at regular intervals by qualified personnel
in compliance with the provisions of statutory legislation and the regulations
in force. LIMIT undergo scheduled servicing at least once every 6 months.
• Disconnect the operator from all power supplies
• Check all the moving parts and renew any worn parts
• Check all parts of the automation system for signs of deterioration
8 SPARE PARTS
Spare parts can be purchased by contacting technical service.
9 DISPOSAL
At the end of its useful life the automation system must be dismantled by
qualified personnel and the materials must be recycled or disposed of in
compliance with the local legislation in force.

10.3 FUNCTIONAL CHARACTERISTICS
OPERATION:
When either the remote or the low voltage pushbutton panel are used to
control the barrier, operation is as follows:
the first command opens the barrier until motor time elapses or the arm
reaches its opening limit position; the second command closes the barrier;
if another command is transmitted during the Opening movement, the
control unit disregards the command; if a command is transmitted during
the Closing movement the control unit reverses the movement direction.
AUTOMATIC CLOSING:
The control unit can be set up to close the barrier automatically without
sending any additional commands.
Selection of this type of operation is described in Pause time programming
mode.
EMERGENCY STOP INPUT:
The control unit allows the connection of an emergency stop pushbutton
(NC). Pressing this pushbutton irrespective of the current operating mode
of the control unit will cause barrier movements to stop immediately. An
additional barrier movement command will be valid, provided the emergency
stop input is deactivated and, in any case, the control unit will perform the
barrier opening cycle after preflashing for 5 seconds.
Important: in Master/Slave applications, if you want to stop the Barriers
simultaneously, the Emergency Stop Inputs of the Master and Slave control
units must be interconnected.
PHOTOCELLS:
Photocells can be powered by and connected to the control unit in
accordance with directive EN 12453.
• Input DS1 (NC)
Tripping of the photocells during opening is disregarded, while during
closing it causes reversal of the direction of movement.
• Input DS2 (NC)
Tripping during opening causes momentary stopping of the barrier; once
the photocell is freed, the control unit resumes the opening movement.
Tripping during closing causes reversal of the direction of movement.
IMPORTANT: in Master/Slave applications tripping of input DS2 causes
exclusively reversal of the direction of movement in the closing stroke.
OPENING AND CLOSING LIMIT SWITCHES:
The control unit allows the connection of Opening and Closing limit switches
(NC). Tripping of the limit switches in the associated operating cycles causes
immediate stopping of barrier movement.
ADJUSTMENT OF MOTOR FORCE DURING THE "NORMAL" CYCLE:
The electronic control unit is equipped with a "SPEED" trimmer for adjustment
of Motor Force during the Normal cycle.
Adjustment can be performed in a range of between 50% and 100% of
maximum force during the Normal cycle.
ADJUSTMENT OF MOTOR FORCE DURING THE "SLOWDOWN" CYCLE:
The electronic control unit is equipped with a "SLOWING" trimmer adjustment
of Motor Force during the Slowdown cycle.
Adjustment can be performed in a range of between 50% and 100% of
maximum force during the Slowdown cycle.
OBSTACLE DETECTION:
The electronic control unit is equipped with a "SENS" trimmer, completely
managed by the microprocessor, for adjustment of the opposing Force
required to detect the presence of an obstacle.
The adjustment can be made with a trip time from a minimum of 0.1 seconds
to a maximum of 1 seconds
