incorporated radio receiver
IMPORTANT NOTICE
The manufacturer reserves the right to introduce modifications without prior notice; the manufacturer does not bear
any responsibility for damage or injury caused by improper use or wrong installation. Before installing and
programming the control unit, carefully read this instruction manual.
- This instruction manual shall only be used by technical staff specialized in automation installation.
- No information contained herein may be of interest to final users.
- All maintenance or programming operation shall only be performed by skilled technical staff.
AUTOMATION SHALL BE PERFORMED IN ACCORDANCE WITH CURRENT EUROPEAN STANDARDS:
EN 60204-1 (Safety of Machinery, electrical equipments of machines, part 1: general rules).
EN 12445 (Safety in use of power operated doors - testing methods).
EN 12453 (Safety in use of power operated doors - requirements).
- The installer shall provide for the installation of a device (for ex. magnetothermic switch) garanting the omnipolar
sectioning of the power supply mains.
- Standards require a minimum contact separation of 3 mm at each pole (EN60335-1).
- Use fittings complying with protection rating IP44 or higher to connect flexible and not flexible pipes or fairleads.
- Installation requires deep knowledge of electricity and mechanics and shall only be carried out by skilled
professionals who shall issue a type. A Declaration of Conformity for the complete installation (EC 89/392 Machinery
Directive, Appendix IIA).
- Following standards for motorised doors shall apply:
EN 12453, EN 12445, EN 12978 and local regulations.
- The electrical system for the automation shall be done to perfection and shall meet current standards.
- The pushing force adjustment of the door shall be measured with a special instrument and adjusted in accordance
with the maximum allowed values of EN 12453 standard.
- The use of an emergency button to be installed near the automation is recommended (connected to the STOP input
on control board).This will stop the gate immediately in case of danger.
- Connect the motor earth wire to the earthing system of the power supply.
OPERATING CHARACTERISTICS
Step-Step Operation: When a one-channel remote control ( LD1 Led on ) or low-voltage button is used to operate
the shutter, the following functional sequence occurs: the first impulse triggers the opening, up to expiration of the
motor time; the second impulse triggers the closing of the shutter. If an impulse is sent before the expiration of the
motor time, then the control unit stops the motion; a further command triggers resumption of the motion, but on the
opposite direction.
Automatic closing: With the control unit, the shutter can be closed in the automatic mode without sending any
additional commands. The set-up for this mode of operation is described in the paragraph “programming of the control
unit”.
Security device: With the control unit it is possible to power and to connect security devices, such as photocells,
pneumatic slats (NC) etc.. The addition does not result in variations in operation during the opening phase, while it
leads to an inversion of the motion during the closing. If not utilised, this input must be bridged.
PROGRAMMING OF THE CONTROL UNIT
Programming of the control board is performed using the buttons SET and the three Dip S1, S2, S3.
SEL Button is used for programming the remote control codes and the central unit reset.
Logic of the DIP S1, S2, S3:
DIP ON OFF
S1 FLASHING LIGHT COURTESY LIGHT
S2 AUTOMATIC CLOSING 30s /
S3 AUTOMATIC CLOSING 60s /
