FUNCTION MODE

Functions selected using the Dip-switch "D1"
Pos. A (Dip 1 "ON" + Dip 2 "ON")
Automatic reclosing + limited dynamic button mode using the
sequence "Open- Close" (with travel direction inversion only
during the closing stage)
Pos. B (Dip 1 "OFF" + Dip 2 "OFF")
Automatic reclosing excluded + normal dynamic button mode
using the sequence "Open-Block-Close-Block"
Pos. C (Dip 1 "ON" + Dip 2 "OFF")
Automatic reclosing excluded + limited dynamic button mode
using the sequence "Open- Close" (with travel direction inver-
sion only during the closing stage)
Pos. D (Dip 1 "OFF" + Dip 2 "ON")
Automatic reclosing + normal dynamic button mode using the sequence
"Open-Block-Close-Block"
1) Automatic
Selected by moving dip 2 to the "ON" position. When the gate/barrier is completely closed
the dynamic command will start a complete cycle ending with automatic reclosing.
Automatic reclosing starts after the programmed pause period has elapsed when the opening
cycle has been completed or straight away after the intervention of a photoelectric cell (the
intervention of a photoelectric cell causes the pause time to be reset). Pressing the blocking
button during the pause time will inhibit automatic reclosing.
The indicator light remains lit until the closing manoeuvre has terminated
2) Semi-automatic
Selected by moving dip 2 to the "OFF" position.
The work cycle is managed using the dynamic command. Once the gate/barrier arrives in
the completely open position the system will wait for a dynamic command (either via radio
or by pressing a button) to complete the cycle.

ALARM CONDITIONS

1) Work time loaded from EEPROM is wrong
LED "LD2" 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 (incor-
rect memorising).
2) 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.
