1 starts to open, motor 2 automatically open after the
open delay time; when both leaf reach the completely
open position, the “AUTO” blinks for 2 seconds on
the display, then the “AUTO” stops blinking, the close
movement starts automatically.
NOTE: the closing delay is set by par.26: it is set by
default to 5”; when the two leaf need a bigger value,
for example if the leaf 1 travel is shorter than the leaf
2, before starting the learn of the length you must set a
closing delay (par.26) bigger enough to avoid a wrong
overlapping.
PROGRAM SEQUENCE FINISH
(FOR TIME MODE AND FOR ENCODER MODE)
If the program is done correctly, the display comes back
to show You the input/safety status.
Otherwise the display will show You the word “APP.E”
(learning error), so You have to repeat again the learning
steps.
The programming is stopped each time a safety is on
(e.g. photocells, safety edge) and the display will show
You the word “APP.E” (learning error).
TEST PHOTOCELLS
If You connect the photocell power to terminal block
“SC” (nr. 34) instead of terminall block 32 and You setted
the parameter “A8=02” on extended mode version, You
enable the photocells test.
The photocells are powered off and on every command
You do and the control unit veries if the contact status
change correctly each time: if it is true the command
enables the motor, otherwise it mantains the stopped
status.
NOTE: in this mode on the terminal block “SC” there is
a 24Vac tension, so it is not possible to use this output
to have information about the gate position.
ERROR COMMUNICATION
The function parameters are memorized on a not volatile
memory (EEPROM) with check code to warranty the
validity; a parameter error is shown on display and at
the same time the control unit is blocked.
E.G.: if there is an error on parameter number 23 the
display will show You the following:
“EE” means an error situation, the control unit is blocked
until You reset the correct value. You have to use the
buttons “+” and “-“ choosing the correct value for the
installation and after You have to save it.
NOTE: a parameter error is shown on extended value,
that You can see on the scheduled at the end of the
instructions, even if it is on the “simple” mode version.
RECOVERY POSITION MODE
When the two leafs close one at time (skipping the
programmed closing delay), rst the leaf 2 and then
the leaf 1, it means that the board is recovering the
references: in this case wait that the ashing light turn
off before give further commands, because the travel
must be complete. If it is incomplete, the movement will
be inaccurate because there are not the right reference
of completely close and open position.
During the recovering movement the ashing light
blinks in a different way (3” on, 1,5” off), to point out this
particular mode: only when the ashing becomes again
regular the board has recovered the references.
The board loose the leaf position information after a
blackout or for the reason described below.
RECOVERY POSITION MODE
WITH ENCODER ENABLED
If the encoder detenction obstacle is on for 3 times on the
same position, it means that there is a stable obstacle
so the control unit start the recovery of the reference.
EXTENDED FUNCTION MODE
Herewith You can see some critical parameters
available on “extended” mode. The table 3 contains all
parameters.
NOTE: if You use the “simple” mode, the not visible
parameter value is shown on the third column (valid for
a new board or after a reset of standard values).
ATTENTION! Some parameters should not be shown
because not needed to the installation, however it
depends on selection mode (e.g.: the 2 limit switches
of motor 2 if we are on the case of single leaf, or the
working time if we work with the encoder).
Automatic closing after pause time (PAR.A2)
To enable the automatic closing it is necessary to set
the parameter on value different from “0”, if You set the
value on 99 You will always have the automatic closing
after pause time.
If You set a value less than 99, this number indicates
the number of reclosing chance.
NOTE: the value of parameter 49 is strictly connected
with the value of parameter A2, the value of parameter
49 must be at maximum the same of the parameter A2.
Automatic closing after blackout (PAR. A3)
if this parameter is set to “01”, after a power on the
