Alarm Conditions - Cardin Elettronica ZVL321.01 Manuel

3) Manual operation
Selected by closing the jumper "J1".
The associated red indicator LED "LD6" will light up. Movement commands can only be given by
continuously pressing the opening or closing buttons. The dynamic button and radio control com-
mands have no effect (it is however possible to use the C-NA contact between binding posts 17
and 18 see fig. 1).
Each time the button is released the gate/door will instantly stop.
The cutting in of a block command or the photoelectric cells (both in the closing and opening direc-
tions) 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 gate/door to stop and the opening/clos-
ing cycle to terminate.
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.
Note: activating a movement command (opening/closing) when one of the command buttons is pressed
(the opposite command) will block all movement; to free the system release all active buttons.

ALARM CONDITIONS

1) Work time loaded from EEPROM is wrong
LED "LD7" will flash 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 EEPROM will have to be replaced (incorrect memoris-
ing).
2) Transmitter code loaded from EEPROM is wrong
LED "LD1" will flash but the system is not blocked:
Reprogram the transmitter code and if you are successful the LED will cease flashing.
3) Both travel limits have cut-in
This situation is indicated by the periodical activation of the flashing warning lamps which are activated
for 3 second periods repeated every six seconds.
The only way to solve this problem is to check the travel limits for obstacles or damage and then
restart the system.
OPERATION WITHOUT USING MECHANICAL CLOSING TRAVEL LIMITS
The system is designed to operate without mechanical closing travel limits; the work time manage-
ment allows the system to control the position of the garage door. The following points however
should be taken into consideration:
1) Due to climatic variations or mechanical wear the performance of the system can change. A work
time programmed without leaving a margin of tolerance (extra time) may not be sufficient to com-
plete the manoeuvre (in other words, over a period of time the garage door may remain slightly
open)
To avoid this situation proceed as follows:
1a) During programming keep the motor under tension for a couple of seconds after the mechani-
cal opening direction travel limit has cut-in (not more than four seconds).
1b) The programmer automatically allows for a 3 second increase in order to guarantee that during
repeated travel direction inversion manoeuvres the forcing movement of the garage door does
not cause this problem.
