Test - Nice OTA 30 Manual De Instrucciones

The following part refers only to the OTTO version
• On the card for the OTTO type gearmotor the output for powering the accessories on terminals 5 and 6 has a direct current
(5 = negative -, 6 = positive +), pay attention to polarity when connecting the accessories. ATTENTION: the direct current
supply on Nice photocells does not allow synchronised functioning (for which alternating current is necessary).
• Current standards state that very low voltage electric circuits must always refer to earth potential. On the unit, terminal 5 (0
volt) is already earthed through the gearmotor's metal structure.

3) TEST:

The plant can be checked and tested once the card has been connected.
ATTENTION: the next operations entail working on live circuits, most of the circuits are in extra low safety voltage so they
are not dangerous but some are under mains voltage which means they are HIGHLY DANGEROUS! Pay maximum attention to
what you are doing and NEVER WORK ALONE!
We recommend working initially with all the functions deactivated (dip-switch Off). Check that all the adjustment trimmers are on
minimum (turned in the counterclockwise direction) only the FORCE commutator can be put on maximum.
A) Unlock the gate or door and, by hand, move the gate to the halfway point; now the gate is free to move in either the opening
or closing direction.
Make sure that all the standards relative to the automatic gates and doors category have been observed!
B) Power the unit and check that voltage between terminals 1-2 is 230 Vac and 24 V dc between terminals 5-6 24 Vdc in the
OTTO version and 24 Vac in the ROBO version.
As soon as the unit is powered the indicator lights (LEDs) on the active inputs should light up
If none of this happens, switch power off immediately and check connections more carefully.
•
D) Check that the LEDs of inputs with NC type contacts are on (all the safety devices active) and that the LEDs of inputs with
NO type contacts are off (no command present); if this does not happen check connections and effectiveness of the various
devices.
E) Check that all the safety devices on the plant are working properly (emergency stop, photoelectric cells, pneumatic edges,
etc.); each time they trigger the corresponding STOP and PHOTOCELL LEDs should turn off.
•
This is one of the most important checks and must be done with great care: in actual fact the "active" safety of the gate
machine depends on the correct functioning of the safety devices. If the flashing light is an excellent instrument for signalling
the state of danger and the torque limiting devices are an excellent means to minimise damage, only a correct installation of
the safety devices will make it possible to block the automatism before it can cause any damage.
F) Now is the time to check whether movement occurs in the right direction, that is, to see whether movement set on the unit
corresponds to that of the gate.
• This check is of paramount importance: if the direction is wrong in some cases (in the semiautomatic functioning mode for
instance), the gate might appear to be working properly; in fact, the OPEN cycle is similar to the CLOSE cycle but with one
basic difference: the safety devices are ignored in the closing manoeuvre which is normally the most dangerous, and they
will trigger in the opening manoeuvre causing the gate to reclose up against the obstacle with disastrous results!
To see whether or not rotation direction is correct, give a short pulse to the Step-by-Step input (with the TL trimmer set on
minimum); the first manoeuvre the unit will carry out after being powered on is always an OPEN one, so simply verify that the
gate starts opening; if movement is wrong you must proceed as follows:
1 - Turn power off
2 - Pull the "MOTOR" connector out and put it back in turning it round 180°
3 - Pull the "LIMIT SWITCH" connector out and put it back in turning it round 180° (only in the ROBO version)
Once this has been done, check if rotation direction is now correct, repeating the procedure described in point "F".
Note: when you reverse direction, it is necessary to carry out all three operations described above. In particular, for instance, if
you turn the "MOTOR" connector but do not do the same for the limit switches, an error will be generated between the control
logic and actual movement of the gate.
