6.1.3 Calibration
Each time the E680 board is powered, the integrated loop detector
performs a calibration of the connected loops. Therefore, you can
perform calibration by cutting off power to the board for at least 10
seconds and then reconnecting it.
From the barrier status display, you can press, at any time, SW4/CAL1
to calibrate the loop connected to the LOOP 1 input or SW5/CAL2 to
calibrate the loop connected to the LOOP2 input.
Calibration is highlighted by the board diagnostics by fl ashing LEDs
DL3 and DL4, and when calibration is completed, they will indicate
the loop detection status, if connected.
The other signals provided by the board diagnostics are described
in the following table:
DL3
DL4
LOOP 1
LOOP 2
2 2 2 2 4 5 6 7
If one or both magnetic loops are not installed, the loop
detector, following a fi rst attempt to calibrate, will keep
the status LEDs fl ashing every 5 seconds (as shown in
the above table)
LED Status LOOP Status

On Loop engaged
Flashing (0.5 s) Loop calibration

Rapid flashing Loop short circuit
Slow flashing
(5 s) No loop
or loop interrupted
Two flashes (every 5 s) Non-conforming loop
(heater or inductance
out of range)
6.1.4 Adjusting sensitivity
By adjusting the sensitivity of the loop detector, you determine the
variation of inductivity, for each channel, that a vehicle must cause in
order to activate the corresponding detector output.
Sensitivity is adjusted separately for each channel using the two
parameters
S1
and
S2
in Basic confi guration
6.1.5 Making the loops
The loop must be laid at least 15 cm from fixed metal objects, at least
50 cm from moving metal objects and no more than 5 cm from the
surface of the final paving.
Use a standard unipolar cable measuring 1.5 mm² in diameter (if
the cable is laid below ground level directly, it must have double
insulation). Make a preferably square or rectangular loop by preparing
a PVC cable duct or by tracing the paving, as shown in figure 16 (the
corners must be cut at a 45° angle to avoid cable breaks). Lay the
cable using the number of windings shown in the table. The two ends
of the cable must be twisted together (at least 20 times per metre)
from the loop to the E680 board. Avoid splicing a cable (if necessary,
weld the conductors and seal the splice using a heat-shrinking sheath)
and keep it separate from the mains power lines.

6.2 Expert Confi guration
EXPERT configuration is used only in the event that operation logics customisation is already stored.
Before making changes at this level, be certain that the steps you wish to change and their effect on the automated
system are fully understood.
Changing the third-level parameters involves indicating the
CU
value on the
LO
parameter of the fi rst-level programming
To access EXPERT configuration, press F and, holding it, press + for approximately 10 seconds .
The use of F , + and - in this menu is the same as in the other two programming levels

01
If this function is activated, automatic closing occurs after the pause time.
Y
= automatic closing
no
= disabled
02
If this function is activated, two distinct input operation mode is obtained: OPEN for
opening and CLOSED for closing.
Y
= 2-input operation
no
= disabled
03
Activation of recognition of the OPEN and CLOSE input levels (maintained command) .
That is to say, the board recognises the level (if, for example, with OPEN held, you press
STOP, when the latter is released, the automated system will continue to open). If
03
is
disabled the board commands a manoeuvre only if there is an input variation.
