Manual Operation; Alarm Conditions - Cardin Elettronica ZVL322.02 Mode D'emploi

3) Manual operation

Selected by closing the jumper "J1". The associated red indicator LED "LD8" will light up. Movement
commands can only be given by continuously pressing the opening or closing buttons. The dynamic
button/limited opening and radio control commands have no effect (it is however possible to use the
C-NO contact between binding posts 15 and 16 see fig. 1). Each time the button is released the gate/
door will instantly stop.
The cutting in of a blocking command or the photoelectric cells (both in the closing and opening
directions) instantly stops all movement: to be able to move the gate/door again you will first have to
release all commands (meaning that no control buttons are active) and then press the required manual
operation button as explained above.
The activation of one of the travel limit switches causes the relative gate to stop and the termination of
the opening/closing cycle as indicated in table 1.
Work cycle time management is also active for this function meaning that even without mechanical
travel limits the system will block when the work cycle time has elapsed. The night light remains on
only while the gate/door is moving.
The indicator light remains lit until the closing manoeuvre has terminated.
Limited opening command (TAL)
The limited opening command, which only works when the gate is completely closed, now functions
in the following way.
1) If your system only has one gate leaf: it will open for about half the work cycle time
2) If your system has two gate leaves: it will completely open gate leaf one.
The following sequence can be carried out by repeatedly pressing the TAL command:
- pressing TAL once:
- pressing TAL twice:
- pressing TAL three timers:
Once closing has started the TAL command has no effect until the gate is completely closed. During
limited opening the "TD" and "TA" commands are however active and will allow the gate to be completely
opened if pressed.
Opening command (TA)
The "TA" command can be continuously activated, e.g. controlled by a timer contact (working in the
"clock" mode): the gate will open completely, and even if automatic reclosing is active, will remain in
pause (flashing line on the display) until the "TA" button is released: at this point after the pause time
has elapsed, the closing cycle will start.
Therefore: activating the "TA" command will cause the pause time to be continuously reset.
If the gate has been blocked using a "TB" command in the completely open position (travel limit activated
or the opening direction work time has elapsed) activating the "TA" command will reset the pause time
after which the gate will move in the closing direction: the "TA" command therefore works as a closing
command if the gate is completely open.

ALARM CONDITIONS

1) Parameters loaded from EEPROM are wrong.
The letter "E" will flash on the display and the system remains blocked:
The only way to solve this situation is to enter the program mode and reprogram the system. If the
problem persists after reprogramming, the problem regards the EEPROM (incorrect memorising). Switch
off the power to the system, after a few seconds switch it back on and then reprogram the system.
2) Both travel limits have cut in (or haven't been correctly bridged, or not excluded via software).
The letter "A" will appear on the display and the system remains blocked. The warning lights will flash
for a three second period which is repeated every six seconds. Once you have eliminated the travel
limit problem the programmer will automatically reset itself. If you do not wish to use the travel limits
disable them during programming (steps 8-9, see page 16).
