Max. Gate Quiescent Time
Some types of actuators (hydraulic actuators, mainly) tend to be
loosened after some hours of quiescent time, jeopardizing the gate
mechanical closing.
Such menu allows setting the max. gate quiescent time from 1 to 8
hours. By setting on 0, this function will be disabled.
In case the gate stays quiescent (closed) for a time longer than the
set time, City1 will close the gate for 10 seconds, so restoring an
effective closing.
Anti-skid
When an opening or closing operation is interrupted by a command or
for the intervention of the photocell, the set-up time for the opposite
movement would be excessive, so the control unit operates the
motors only for the time necessary to recover the actually covered
journey. This could be not sufficient, particularly in the case of very
heavy gates, as because of the inertia at the inversion moment the
gate runs an extra space in the previous direction that the control unit
is not able to take into account.
If after an inversion the gate does not return exactly to the starting
position, it is possible to set an anti-skid time that is added to the
time calculated by the control unit in order to recover the inertia.
WARNING: If function ASM is disabled, the gate goes backward
until it comes to the end stops. In this phase the control unit does not
activate the slow down function before the end stops are reached and
any obstacle that comes across after the inversion is considered as
an end of stroke.
Obstacle Sensor Enabling
This menu allows the sensitivity adjustment of the obstacle sensor
over 10 levels, from 1 to 10. By setting up "0", sensors will be
disabled, increasing the value the sensivity increase.
The control unit automatically adjusts the sensor on the most suitable
level, according to each motor set up power.
In case the safety operation is deemed not to be fast enough, the
sensitivity level can be slightly increased.
If the gate stops where no obstacles are present, you should reduce
the sensitivity level.
(See paragraph "Obstacle sensor operation" hereafter).
Counter viewing
This menu allows viewing the counter of completed
opening cycles and it also enables the final user to
set up the times of service required (see paragraph
"Reading of cycle counter" below).
