6 Testing - Nice Wil Instructions Et Recommandations Pour L'installateur

Traffic light in both directions:
The function of the traffic light in both directions is mainly to control the flow of traffic in both directions as they go across the controlled road
barrier. A different command is placed for opening in both directions: P.P. for entering and P.P.2 (Open) for leaving; two traffic lights are
installed with the indications Red and Green, connected to the Bar Open Indicator and Courtesy Light outputs.
The two outputs are usually off and so are the two traffic lights; when a command is given with P.P. to enter, movement is started and the
Bar Open Indicator output is activated: this means there will be a green light to enter and a red light to leave.
But should the command be given with the P.P.2, the Courtesy Light output will be activated and there will be a green light to leave and a
red light to enter. The light will stay on for the entire opening manoeuvre and for the subsequent pause time; during the closing manoeuvre
both the green and red lights will be activated (the result being yellow) to indicate there is no longer any transit priority (see table).
Red Green Meaning:
OFF OFF Bar closed, no passage in either direction
OFF ON Bar open, free transit
ON OFF Bar open, transit occupied
ON ON Bar closing and transit not controlled
The two Bar Open Indicator and Courtesy Light outputs can directly control small 24 V d.c. lamps for a total of 10 W. If stronger lamps have
to be used, use the relays piloted by the unit outputs that control, in turn, the traffic lights.

This is the most important stage in the automation system instal-
lation procedure in order to ensure maximum safety levels. Testing
can also be adopted as a method of periodically checking that all the
various devices in the system are functioning correctly.
Testing of the entire system must be performed by qualified and
experienced personnel who must establish which tests to conduct
on the basis of the risks involved, and verify the compliance of the
system with applicable regulations, legislation and standards, in par-
ticular with all the provisions of EN standard 12445 which establish-
es the test methods for automation systems for gates.
We recommend working in the manual mode with all the functions
deactivated (dip-switches OFF); in all cases, when you are working
in the manual mode and you release the control key the motor will
stop immediately.
Each component of the system, e.g. safety edges, photocells, emer-
gency stop, etc. requires a specific testing phase, we therefore rec-
ommend observing the procedures shown in the relative instruction
manuals.

Ensure that the instructions outlined in this manual and in particular
in chapter 1 "WARNINGS" have been observed in full.
A) Check that the bar is well balanced, adjusting the balancing
spring if necessary.
Release the boom gate using the special spanner and check that
the bar can move without any effort for the whole length of travel.
B) Power the unit and check that voltage between terminals 1-2 and
1-3 is 230 / 120 Vac and 24 V a.c. between terminals 21-22.
As soon as the unit is powered the indicator lights (LEDs) on the active
inputs should light up; in addition, the "OK" LED should start flashing
almost immediately afterwards at regular intervals. If none of this hap-
pens, switch power off and check connections more carefully.
• The task of the "OK" LED, in the centre of the card, is to signal
the state of the internal logic: regular flashing at 1 second inter-
vals means the internal microprocessor is working and waiting for
commands. On the other hand, when the same microprocessor
recognises a variation in the state of an input (be it a command
input or function dip-switch), a double, quick flashing is generat-
ed even if the effects of the variation are not immediate. Extra fast
flashing for 3 seconds means that the unit has just been powered
