7.4 SPECIAL FUNCTIONS
7.4.1 "Always open" function
The "Always open" function is a control unit feature that enables
the user to always command an opening manoeuvre when the
"Step-by-Step" command lasts longer than 2 seconds; this is
useful, for example, for connecting a timer contact to the Sbs
terminal in order to keep the gate open for a certain time frame.
This feature is valid regardless of how the "Sbs" input is pro-
grammed, unless it is programmed to perform the "Condomini-
um 2" function. Refer to the "Step-by-Step function" under the
"Level 2 programming (adjustable parameters)" paragraph.
7.4.2 "Move anyway" function
This function can be used to operate the automation even one
or more some safety devices fail to work properly or are out of
order. The automation can be controlled in "hold-to-run" mode
by proceeding as follows:
send a command to operate the gate, using a transmitter
1.
or key selector, etc. If everything functions properly, the
gate will move normally, otherwise proceed with point 2
within 3 seconds, press the control again and hold it down
2.
after roughly 2 seconds, the gate will complete the re-
3.
quested manoeuvre in "hold-to-run" mode, in other
words, it will continue to move so long as the control is
held down.
l
When the safety devices fail to work, the warn-
ing light will emit a few flashes to signal the
type of problem. To verify the type of anom-
aly,
consult
(troubleshooting guide)" chapter.
7.4.3 "Maintenance notice" function
This function notifies the user when the automation needs a
maintenance check. The number of manoeuvres after which the
signal is triggered can be selected among 8 levels, through the
"Maintenance notice" adjustable parameter (see paragraph "
Level 2 programming (adjustable parameters)").
Level 1 adjustment is "automatic" and takes into account the
severity of the manoeuvres, in other words, their force and dura-
tion, while the other adjustments are defined on the basis of the
number of manoeuvres.
The maintenance signal is sent through the Flash warning light
or the maintenance indicator, depending on the relative settings
(see paragraph "Level 2 programming (adjustable parame-
ters)").
l
The "Flash" warning light and the maintenance in-
dicator give the signals indicated in "Table 7" based
on the number of manoeuvres completed with re-
spect to the set limit.

10%) with respect to the set limit. For example: with the
maintenance notice set to L7 namely 40000, 10% cor-
responds to 4000 manoeuvres; if the visualisation LED
flashes 4 times, it means that 40% of the manoeuvres
has been reached (being between 16000 and 19999
manoeuvres). If 10% of the manoeuvres has not yet
been reached, the LED does not flash at all.
