During normal operation, the display present on the LIBRA C MV control
panel shows the following information:
STOP = STOP input activation
BAR
= EDGE input activated (obstacle alarm)
AMP
= ampere-stop triggering (obstacle alarm)
ENC
= encoder stopped detected (obstacle alarm)
PHOT = PHOT input activation
FLTF
= FAULT input activation for checked photocells
TIME
= TIMER input activation
TTCA = waiting time for automatic closing on TIMER release
CLS
= CLOSE input activation
OPEN = OPEN input activation
STRT = START input activation
SWO
= barrier in opening position
SWC
= barrier in closing position
REFO = reference input on opening activated
REFC = reference input on closing activated
TH
= overload signal indication (the system completes the manoeuvre
in progress and does not allow new ones until the signal indica-
tion has been eliminated).
In case of malfunctions, the display shows a message indicating which
device needs to be checked:
ER0X = check on safety devices failed
ER1X = check on motor control failed
ER2X = encoder direction wrong (power supply cables for motor or
encoder signal reversed)
ERX = overload error (the system remains under protection lock until
the error has been corrected).
EREF = error due to position references both active.
15.7) Statistics
With the use of the universal programmer, you can consult the statistical
parameters stored in the control panel memory:
-
Board microprocessor software version.
-
Number of cycles carried out. If motors are replaced, count the number
of manoeuvres carried out up to that time.
-
Number of cycles carried out from the latest maintenance operation.
It is automatically set to zero after each self-diagnosis or parameter
writing.
-
Date of latest maintenance operation. To be updated manually from
the appropriate menu "Update maintenance date".
-
Installation description. 16 characters can be entered for installation
identification.
16) CONNECTION TO PARKY CAR-PARK MANAGEMENT SYSTEM
The board can be configured in order to make an output available for
controlling the barrier status. When the SCA Alarm logic is disabled (OFF)
and the Alarm Time parameter is set to 0 s, the SCA contact (JP12 21-22)
is configured as follows (Fig.17):
- contact closed between terminals 21-22 with the barrier lowered
- contact open between terminals 21-22 with the barrier lifted
17) LIMIT SWITCH SETTING
WARNING: before opening the door, the spring must be unloaded
(vertical boom). The barrier is provided with programmable electronic limit
switches and mechanical stop devices. There must be a rotation margin
(about 1°) on closing and opening between the electrical limit switches and
mechanical stop devices (fig.9). The adjustment is carried out as follows:
The end-of-stroke opening and closing positions must be set by modifying
the parameters of the control panel for Opening value Calibration and Clos-
ing value Calibration: if the value is increased, the end-of-stroke positions
move towards the opening direction. The extent of the movement depends
on the effective boom length: in the case of a 6-m boom, a unit change
(1.0) entails a movement of about , cm which, proportionally, becomes
about 5,8 cm for an 8-m boom.
The effective closing value also depends, in part, on the manoeuvring
speed. It is therefore convenient to proceed to end-of-stroke calibration
only after having set the other opening parameters.
To evaluate correctly the values set, you are advised to carry out a few
complete consecutive manoeuvres.
18) EMERGENCY RELEASE (Fig.11)
The emergency release allows the bar to be manoeuvred manually. It is
activated from the outside of the box by inserting the personalised key into
the lock placed under the bar and rotating it anticlockwise by 90°.
WARNING! When an actuator without bar needs to be released, ensure that
the balancing spring is not compressed (bar in the opening position).
19) USE OF AUTOMATION
As automation can be remotely controlled and therefore not within sight, it is
INSTALLATION MANUAL
essential to frequently check that all safety devices are perfectly efficient.
WARNING! In case of any malfunction in the safety devices, take imme-
diate action and require the assistance of a specialised technician.
It is recommended to keep children at a safe distance from the automa-
tion field of action.
20) CONTROL
The automation system is used to obtain motorised access control. There are
different types of control (manual, remote, magnetic badge, mass detector
-Fig.20- etc.) depending on the installation requirements and characteristics.
For the various control systems, see the relevant instructions.
21) MAINTENANCE
WARNING: before opening the door, the spring must be unloaded
(vertical boom). WARNING: Before carrying out any maintenance to the
installation, disconnect the mains power supply. The following points need
checking and maintenance:
-
Photocell optics. Clean occasionally.
-
Electric edge. Carry out a periodical manual check to ensure that the
edge stops the bar in case of obstacles.
-
Dismantle the gearmotor and replace the lubricating grease every two
years.
-
When any operational malfunction is found, and not resolved, disconnect
the mains power supply and request the assistance of a specialised
technician (installer). When the operator is out of order, activate the
emergency release (see paragraph 18), if necessary, so as to release
the manual boom opening and closing operations.
22) SCRAPPING
Materials must be disposed of in conformity with the current regulations.
In case of scrapping, the automation devices do not entail any particular
risks or danger. In case of recovered materials, these should be sorted out
by type (electrical components, copper, aluminium, plastic etc.).
23) DISMANTLING
WARNING: before opening the door, the spring must be unloaded
(vertical boom). When the automation system is disassembled to be
reassembled on another site, proceed as follows:
-
Disconnect the power supply and the entire electrical installation.
-
Remove the actuator from its fixing base.
-
Disassemble all the installation components.
-
In the case where some of the components cannot be removed or are
damaged, they must be replaced.
24) MALFUNCTION: CAUSES and REMEDIES
24.1) The bar does not open. The motor does not turn.
WARNING: before opening the door, the spring must be unloaded
(vertical boom).
1) Check that the photocells are not dirty, or engaged, or not aligned.
Proceed accordingly. Check the electric edge.
2) Check the correct connection of the drive motor and capacitor.
3) Check that the electronic appliance is correctly supplied. Check the
integrity of the fuses.
) Use the control unit self-diagnosis (see par. 1.6), to check whether
the functions are correct. Identify any possible cause for the fault. If
self-diagnosis indicates that a start command persists, check that there
are no radio transmitters, start buttons or other control devices keeping
the start contact activated (closed).
5) If the control unit does not work, it must be replaced.
6) Check the activation of the reference microswitches by checking the
messages appearing on the control panel display.
24.2) The bar does not open. The motor turns but there is no movement.
1) The manual release was left engaged. Reset the motorised operation.
2) If the release is in the motorised operation position, check the gearmo-
tor for integrity.
