Introduction; Description; Installation Instructions - Nice OTA 30 Manual De Instrucciones

English

1) INTRODUCTION:

This instruction manual refers to two versions of the same electronic card, the differences are minimal and appropriately
highlighted; check the label on the card in the case of doubt.
- OTA 30 for OTTO KCE model gearmotors suitable for overhead swing doors
- ROA 30 for ROBO KCH model gearmotors usable on sliding gates
The electronic unit is designed to control the movement of automatic gates and doors, controlled by electromechanical actuators
with single-phase asynchronous motors running on 230 Vac, in our case the models OTTO or ROBO made by Nice.
Both "semiautomatic" and "automatic" operations are possible with this unit; while the gate or door is moving the consents are
controlled by the safety devices (STOP and PHOTOCELL inputs). In the version for OTTO movement is to time and the limit
switches are an optional while in the version for ROBO movement limits are verified by a limit switch. On the OTTO model the
special limit switch kit can be used later on.
Effective techniques have been adopted in the project to guarantee maximum reliability and safety, good flexibility of use and
what is essential for the programmable functions.
All the units are designed for connecting a wide range of Nice made radio receivers.

1.1) DESCRIPTION:

Each product of this kind is always different from other similar ones so before you proceed to its installation we have listed here
a brief description of the most important elements on the card.

When the unit is powered the LEDs (15), which are on the inputs, turn on if that particular input is active and if there is a control
voltage of 24 V. As a rule, the LEDs on the safety device inputs STOP and PHOTOCELL are always on while the one on the
STEP-BY-STEP command input is off. A description of the other elements and their functions is given below in the instructions.
2) INSTALLATION INSTRUCTION:
Remember there are specific standards that have to be strictly followed regarding the safety of electrical installations and
automatic gates and doors!
Besides these standards, that refer to electrical installations in general, machine systems and automatic doors and gates, here
are some other specific notes for this unit that will make the whole system even more safe and reliable:
The power line leading to the unit must always be protected by a magnetothermic switch or by a couple of 5A fuses, a
•
differential switch is recommended but not essential if there is already one before the system.
Power the unit using a 3 x 1.5 mm2 cable (phase + neutral + earth); should the distance between the unit and the earth
•
connection exceed 30 metres, an earth plate must be installed near the unit.
It is absolutely forbidden to connect cables in buried boxes even if they are completely watertight.
•
For the connections of the low voltage safety part (terminals 5...14) use wires with a minimum cross section of 0.25 mm2.
•
Use shielded wire if the length exceeds 30 metres, connecting the earth braid only on the unit side.
Always and only use doubly insulated cables and never single wires even if they are protected inside ducts.
•
Whether the unit is installed outdoors or indoors it is essential to carry out an in-depth analysis of the surrounding environment.
•
Carefully evaluate hazards deriving from accidental knocks (the transit of vehicles, the falling of parts of trees, etc.), the chance
of coming into contact with foreign parts (insects, leaves ...), the risk of flooding or anything else even of an exceptional nature.
