Description Of Connections; Notes On Connections - Nice OTA 30 Manual De Instrucciones

English
If the inputs of the NC (Normally Closed) contacts are not used they should be jumpered; if there is more than one then they
should be placed in SERIES with one another; if the inputs of the NO (Normally Open) contacts are not used they should be left
free and if there is more than one then they should be placed in PARALLEL with one another. The contacts must be of the
mechanical type and free from any potential; no connections are allowed like those defined as "PNP", "NPN", "Open Collector"
etc., etc.
Remember that there are specific, strict standards that must be complied with both as regards the safety of the electrical
systems and as regards automatic gates and machines.
2.3) DESCRIPTION OF THE CONNECTIONS:
Here is a brief description of the possible connections of the unit to the outside:
1-2 : 230 Vac
3-4 : Flashing light
The following part refers only to the ROBO version
5-6 : 24 Vac
7-8 : GATE OPEN INDICATOR = Output for gate open indicator light 24 Vcc, maximum power of the indicator light 3 W
The following part refers only to the OTTO version
5-6 : 24 Vdc
7 : FCA Limit Switch
8 : FCC Limit Switch
9-10 : Stop
11-12 : Photocell
13-14 : Step-by-Step
41-42 : 2nd Radio Ch
43-44 : Antenna
There is a connector on the card for plugging in Nice RADIO receivers.
We recommend waiting until installation is complete to plug in the optional RADIO card and only after having checked that the
system is working properly. The RADIO card is not necessary for the working of the system and if used will make troubleshooting
more complex.
Only qualified, expert personnel may carry out installation and subsequent maintenance, in compliance with the DPR N°
46 dated 5/3/1990, in total observance of the UNI 8612 standards and following the best indications dictated by "expert
workmanship". Whoever carries out these jobs is held responsible for any damage caused.
2.4) NOTES about CONNECTIONS:
For the most part, connections are easy; a lot of them are direct connections to a single user point or contact but some are a
little more complex:
• Connect mains power to terminals 1 and 2 (1 = Neutral, 2 = Phase), the earth wire must be connected to its terminal with
wire terminal on the body of the gearmotor.
• The output for connecting the flashing light LUCY on terminals 3 and 4 has a fixed voltage so it is necessary to use a flashing
light that has an internal card that causes the flashing.
