6.1) Description of functions
Here is a brief description of the functions that can be added by moving the relative Dip-Switch to “ON”.
Switch 1-2: Off-Off
= “Manual” movement (man present)
On-Off
= “Semiautomatic” movement
Off-On
= “Automatic” movement (automatic closing)
On-On
= “Aut Always Closes” movement
In the “Manual” operating mode, the gate will only move as long as the relative control button is held down.
In the “Semiautomatic” operating mode a command impulse will perform the whole movement until the Working Time limit expires or the
mechanical stop is reached. In the “Automatic” operating mode, an opening manoeuvre is followed by a pause and then an automatic closing
manoeuvre.
The “Always Closes” function comes into play following a power failure; if the gate is open, a closing manoeuvre takes place, automatically
preceded by 5 seconds of pre-flashing.
Switch 3:
On
= Condominium operating mode (not available in the Manual mode)
In the Condominium operating mode, once an opening manoeuvre has started it cannot be interrupted by other command pulses on “Step-
by-Step” until the gate has finished opening.
During a closing manoeuvre, a new command pulse will stop the gate and reverse the direction of movement in order to open the gate.
Switch 4:
On
= Pre-flashing
A command impulse activates the flashing lamp followed by movement 5 s later (2 s later in the manual mode).
Switch 5:
On
= “Close” 5 s. after Photo <in the “Automatic” mode > or “Close” after Photo <in the “Semiautomatic” mode >
This function, if in the “Automatic” mode, allows the gate to be kept open only for the time required for transit; when “Photo” finishes, the
manoeuvre stops. After 5 s a closing manoeuvre will automatically begin. If “Photo” triggers in the “Semiautomatic” mode during a closing
manoeuvre the “Automatic” closing manoeuvre is activated with the adjusted pause time.
Switch 6:
On
= Safety “Photo” also during the opening manoeuvre
The “Photo” safety device is normally just active during the closing manoeuvre; if Dip-Switch 6 is turned "On" the safety device will also trigger
during the opening manoeuvre.
In the “Semiautomatic” or “Automatic” modes, the opening manoeuvre will start again immediately after the photocell has been disengaged.
Switch 7:
On
= Gradual departure
Starts the manoeuvre gradually, preventing the automatic system from being jolted.
Switch 8:
On
= Deceleration
Deceleration reduces speed to 30% of rated speed in order to limit the force of the impact in the gate’s opening and closing areas.
Once the deceleration function has been activated, it will be necessary to adjust the Working Time Trimmer (TL), since the starting of
deceleration is connected with the established working time. Therefore, adjust the working time to ensure that deceleration starts
approximately 50-70 cm before the triggering of the limit switch.
As well as reducing the speed of the manoeuvre, the deceleration function also reduces motor torque by 70%.
For systems requiring elevated torque, this decrease may cause the motor to stop immediately.
Switch 9:
On
= Brake
At the end of the movement a motor brake procedure is performed, initially slight and then more incisive in order to stop the gate rapidly but
without jolts.
Switch 10:
On
= Phototest
This function controls photocell efficiency at the beginning of each manoeuvre. See the “Phototest” chapter.
