Connection Instructions - Nice WIL Manual De Instrucciones

2.3) INSTRUCTIONS FOR CONNECTIONS:
To safeguard the operator and to prevent damaging components when carrying out the connections, whether in low voltage (230
V) or extra low voltage (24 V), or when plugging in the cards:
the unit must, under no circumstances, be electrically powered
We recommend waiting until installation is complete to plug in the optional cards RADIO or CHARGE and only after having
checked that the system is working properly. The optional cards are not necessary for the working of the system and if they are
used they make troubleshooting more complex.
We would also like to remind you that 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. As regards the contacts, they must only be the mechanical type and free from any potential; no connections are allowed
like those defined as "PNP", "NPN", "Open Collector", etc., etc.
A) Carry out the necessary connections, following the diagram in Fig. 3; remember that there are specific standards that must
be complied with both as regards the safety of the electrical systems and as regards automatic gates
B) Check that the bar is well balanced and adjust if necessary by means of the balancing spring. Release the boom gate with
the spanner and make sure the bar can move without any effort for the whole length of its travel.
Do not supply power to the "Wil" boom gate unless all the standards for the automatic gate category have
been complied with!
C) Supply power to the unit, checking immediately that a voltage of 230 V a.c. reaches terminals 1-2 and a voltage of 24 V d.c.
reaches terminals 5-6. As soon as the unit is switched on the indicator lights (LEDs) on the active inputs should turn on and after
a moment, the "OK" LED should start flashing at a regular rhythm. If none of this happens, switch off immediately and check the
connections more carefully.
D) Check correspondence of the two LEDs, FCA and FCC: when the bar is closed only the FCC LED should turn off and when
it is open only the FCA should turn off.
To exploit the slowing down function it is necessary that the limit switch triggers about 20° before the actual stopping point is
reached; if necessary adjust the two cams until the limit switch triggers at the point required.
E) Now check that the LEDs corresponding to the inputs with NC type contacts are on (all the safety devices are active) and that
the LEDs corresponding to inputs of the NO type are off (no command present); if this does not happen check connections and
effectiveness of the various devices.
F) Check that all the safety devices of the system are in proper working order (emergency stop, photocells, pneumatic edges,
etc.); each time they trigger the relative LEDs, STOP, PHOTOCELL or PHOTOCELL 2, should turn off.
G) Check that all the function switches are in the "OFF" position. This means it is in the manual functioning mode, that is, with
the button pressed. Lock the boom gate with the bar at a 45° angle so it can move freely in both directions. Now give a brief
command pulse on the OPEN input and if the bar does not move in the opening direction proceed as follows:
1 ) Turn the electricity off to the boom gate
2 ) Unplug the "MOTOR" connector and replug it after it has been turned 180°
3 ) Unplug the "LIMIT SWITCH" connector and replug it after it has been turned 180°
Repeat the procedure described above in point G to see if rotation direction is right.
Note:
When direction is reversed then all the three procedures described above have to be carried out. In particular, if, for example,
you turn the "MOTOR" connector but not the "LIMIT SWITCH" connector it will cause an error in the slowing down system. In
such a case, the motor is controlled, for instance, in the opening phase but the FCA limit switch is never reached and
consequently the bar reaches the opening point with maximum force; the ammetric detecting system then comes into play
reversing direction in a new manoeuvre which is also wrong.
H) Temporarily adjust trimmers STOP_AMPERE and WORKING FORCE to the maximum length of travel, PAUSE TIME to
minimum and then adjust SLOWING DOWN FORCE to half travel.
I) Try and carry out a complete manoeuvre until the bar reaches the point where the limit switch triggers; the braking system
should come into play at this point and travel ought to continue for a further 3 seconds at a slower speed.
J) Adjust trimmers WORKING FORCE and SLOWING DOWN FORCE so that the manoeuvre is carried out at the speed and
with the force required and that the slowing down phase is such that the bar reaches the stopping points as "gently" as possible
without any jerking; of course, a perfect adjustment of the balancing spring is fundamental.
K) Lastly adjust the trimmer STOP_AMPERE so the obstacle detecting system, based on an ammetric friction system, is
activated as soon as an appropriate opposite action is applied to the bar. The ammetric friction system comes into play in both
directions.
