memory data; therefore, if you plan to carry out replacement cloning
operations by remote control, you need to memorise the contents of the
receiver memory by reading it using UNIRADIO and entering it in the
EEdbase database.
NOTE: For installations in the “collective receivers” mode, it is advisable
to create a complete installation database, by means of EEdbase, containing
the data for each receiver and transmitter, and to number progressively
each memorised transmitter, in order to be able to carry out additional or
replacement cloning operations, even years later, without needing to make
changes directly to the receivers. Refer to the UNIRADIO instructions and
to the on-line EEdbase software guide.
WARNING!: The cloning procedures specified in paragraph 11 give a
simplified explanation of how to carry out cloning, without having the clones
created contained in a database.
Refer to the UNIRADIO instructions for further information concerning the
creation and management of a database.
12) CENTRALISED SERIAL CONNECTION (only available for SCE-MA S)
As well as having local commands, the control unit is preset to operate in
a centralised system, divided into several “zones” which group protocol-
compatible devices. A master device must be selected for each zone,
keeping in mind that the commands given from this device are executed by
all the other devices belonging to the same zone.
A “centralised” command can therefore be sent via wire by means of the
master panel to a given zone: the devices contained in that zone will carry
out the said command. Besides deciding on the zone master panel, you
must configure the zone address for each device included in the centralised
installation. The SCE panel can be included in the centralised installation
both as zone master and as slave (only carrying out commands).
Moreover, a centralised installation via wire can be obtained both by closing
the connection loop (fig.29) and by leaving the connection loop open. With
the loop closed, each zone master unit is able to check command completion
by each slave unit, and to update certain statistics relating to loop
composition; the failed commands will therefore be repeated after a few
minutes. With the loop open, these operations cannot be carried out, all the
other functions however remaining unchanged.
This is why it is necessary to carry out zone number setting, master / slave
setting and closed-loop / open-loop setting for each device. Here follows
the procedure used to set these parameters.
12.1) Programming of centralised installation through display
The display programmer available in the board is used to set all the SCE
control panel functions. Make reference to Fig. A and B. Set the zone
number from the PARAM. Menu, and set the closed-loop / open-loop and
master / slave values from the Logic menu.
12.2) Programming of centralised installation through Unipro
Connect the UNIPRO programmer to the control unit by means of the
UNIDA accessory (see fig. 26). The SCE control unit does not supply power
to the UNIPRO programmer which therefore requires an appropriate supply
unit or charged batteries. Enter the “CONTROL UNITS” menu, the
“PARAMETERS” submenu, and the “SPECIAL PARAMETERS submenu;
then scroll the display screenfuls using the up/down arrows, and set the
numerical values of the parameters listed below.
- Configuration (1) [ 1 ]
Enter the zone number
Enter the “CONTROL UNITS” menu, the “LOGICS” submenu, and the
“SPECIAL LOGICS” submenu; then scroll the display screenfuls using the
up/down arrows, and set the numerical values of the parameters listed
below.
- Address (11 ) [ 0 ]
ON activates closed loop
OFF open loop
- Address (12) [ 0 ]
ON master
OFF slave.
13) DIAGNOSTICS AND MONITORING
The display on the SCE panel shows some useful information, both during
normal operation and in the case of malfunctions.
Diagnostics:
In the case of malfunctions, the display shows a message indicating which
device needs to be checked:
STRT = START input activation
STOP= STOP input activation
PHOT= PHOT input activation
FLT = FAULT input activation for checked photocells (only SCE-MA and
SCE-MA S)
In the case where an obstacle is found, the SCE panel stops the door and
activates a reverse manoeuvre; at the same time the display shows the
“AMP” message.
Monitoring:
During the opening and closing phases, the display shows four digits
separated by a dot, for example 35.60. The first two digits are constantly
updated during the manoeuvre, and represent the maximum torque reached.
The last two digits represent the torque value set in the parameter menu.
These values allow the torque setting to be corrected.
If the maximum torque value reached during the manoeuvre gets sensibly
close to the value set, malfunctions may occur in the future following wear
or slight door deformation.
It is therefore advisable to check the maximum torque reached (the first two
digits) during some of the manoeuvres carried out in the course of
installation, and if necessary set a value about 15-20 percent points higher
in the parameter menu.
14) STATISTICS
The statistics are only managed through UNIPRO. Therefore connect the
UNIPRO programmer to the control unit, enter the CONTROL UNITS/
STATISTICS menu and scroll the screenful displaying statistical parameters:
- Board microprocessor software version
- Number of cycles carried out. If the motors are replaced, take down the
number of manoeuvres carried out up to that time.
- Number of cycles carried out since the latest maintenance operation. It
is automatically set to zero after each self-diagnosing or parameter
writing operation.
- Date of latest maintenance. To be manually updated from the appropriate
“Update maintenance date” menu.
- Installation description. Allows you to enter 16 characters identifying the
installation.
- Number of zone operating units (advanced statistics) Address 16:
indicates the number of actuators belonging to the same zone as that of
the master (only updated in the master boards).
- Number of total operating units (advanced statistics) Address 17:
indicates the number of actuators connected (only updated in the
master boards).
15) CHAIN TIGHTENER ADJUSTMENT
The operator supplied is already calibrated and inspected. Should the chain
tension need to be adjusted, proceed as shown in fig. 17.
WARNING: The anti-tear spring must never be completely compressed.
Scrupulously check that the spring does not become totally compressed
during operation.
16) LIMIT-SWITCH ADJUSTMENT MENU
The SCE control panel is provided with an adjustment menu for opening
and closing limit switches, which simplify the installation procedure.
Making reference to Fig. 18 and 19, and Fig. B showing control panel
programming, proceed as follows:
• Initiate a limit-switch adjustment operation by moving to the appropriate
SCE panel menu (Fig.B).
• When the “CLOSE” message is displayed, bring the door to the required
closing position using the “+” and “-” control unit buttons, keeping in mind
that the “-” button closes the door whereas the “+” button opens the door.
As soon as the door is in the required closing position, press the “OK”
button in order to memorise the closing limit-switch position.
• When the “OPEN”, message is displayed, bring the door to the required
opening position using the “+” and “-” control unit buttons. As soon as the
door is in the required opening position, press the “OK” button in order
to memorise the opening limit-switch position.
NOTE: These manoeuvres are carried out in “ hold-to-run” mode at
reduced speed and without any safety device intervention.
• Now the control panel initiates a partial closing manoeuvre, in order to
allow the reference cam to be positioned, then displays the message
“REF” and moves to the wait mode.
The cam is to be positioned (Fig.19) at a distance of approximately 230
mm from the fixing base. This measurement can vary by approximately
± 13 mm depending on the chain pitch.
Warning!! The cam is to be positioned as shown in details 9A and 9B
of fig. 19. Any incorrect cam positioning can cause damage to the
operator.
• After positioning the cam, press the “OK” button, the control unit initiates
reopening the door to memorise the encoder reference cam positioning.
• At this point the limit-switch adjustment can be considered complete, now
proceed to the autoset operation to complete the operator setting up.
