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,
calibrate the loop connected to the LOOP 1 input or
the loop connected to the LOOP2 input.
Calibration is highlighted by the board diagnostics by flashing 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:
LED Status
Off
On
Flashing (0.5 s)
Rapid flashing
Slow flashing
(5 s)
Two flashes (every 5 s) Non-conforming loop
2 2 4 5 6 7 2 2
If one or both magnetic loops are not installed, the loop
detector, following a first attempt to calibrate, will keep
the status LEDs flashing every 5 seconds (as shown in
the above table)
6.2 Expert Configuration
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
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
"EXPERT" CONFIGURATION

If this function is activated, automatic closing occurs after the pause time.
02
If this function is activated, two distinct input operation mode is obtained: OPEN for
opening and CLOSED for closing.
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
03
STOP, when the latter is released, the automated system will continue to open). If
disabled the board commands a manoeuvre only if there is an input variation.
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

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)
