6) Operating modes:
In the manual operating mode, the OPEN input enables the opening
manoeuvre and the CLOSE input enables the closing manoeuvre.
The STEP-BY-STEP input enables an alternating closing and opening
manoeuvre.
Movement stops as soon as the command in input stops. If the limit
switches trigger, or PHOTOCELL 2 (on the PIU card) fails to enable
movement during an opening manoeuvre, movement will stop;
during a closing manoeuvre, on the other hand, movement will also
stop if PHOTOCELL does not enable movement. Both in the opening
or closing phases, movement will be brought to an abrupt halt by
means of STOP. When a movement is stopped, stop the command
in input before a new command is given that starts a new movement.
When one of the automatic functioning modes (semiautomatic,
automatic or always closes) is operational, a command impulse on
the OPEN input will begin an opening manoeuvre. An impulse to the
STEP-BY-STEP input begins an alternating closing and opening
manoeuvre. A second impulse on the STEP-BY-STEP input or on the
same input that started movement will cause it to stop.
Both in the opening or closing phases, movement will be brought to
an abrupt halt by means of STOP.
If, a command input is given a continuous signal instead of an
impulse, a state of “priority” will be created in which the other
command inputs are disabled (this is useful if you want to connect a
timer or a Night-Day selector).
If an automatic functioning mode has been chosen, the opening
manoeuvre will be followed by a pause and then by a closing
manoeuvre. If PHOTOCELL triggers during the pause, the timer will
be reset with a new pause time; if, on the other hand, there is a STOP
during the pause, the closing function will be cancelled and the
system will STOP.
Nothing will happen if PHOTOCELL triggers during an opening
manoeuvre but if PHOTOCELL 2 (on the PIU card) triggers, this will
invert the direction of movement; if PHOTOCELL triggers during a
closing manoeuvre, this will invert the direction of movement followed
by a pause and then by a closing manoeuvre.
The unit features a set of microswitches used to operate various
functions so as to make the system more suitable to user needs and
safer in various conditions of use. All the functions can be activated
by moving the relative dip-switch to the “On” position and
deactivated by moving them to “Off”.
ATTENTION: some of the programmable functions are connected
with safety aspects; carefully evaluate the effects of a function and
see which function gives the highest possible level of safety.
When servicing a system, before modifying a programmable function,
find out why certain decisions were made during installation and then
make sure the level of safety will not be impaired by the modified
programme.
7) Programming:
7.1) Programmable functions:
Use the FUNCTIONS dip-switch to select the various functioning modes and add the functions required according to this table:
Switches 1-2:
Off-Off
= “Manual” movement (Man Present)
On -Off
= “Semiautomatic” movement
Off-On
= “Automatic” movement (Automatic Closing)
On -On
= “Aut always closes” movement
Switch 3:
On
= Condominium operating mode <Not available in the Manual mode>
Switch 4:
On
= Pre-flashing
Switch 5:
On
= Close again 5” after Photocell <only in the automatic mode>
Switch 6:
On
= “Photocell” also in opening
Switch 7:
On
= Phototest
Switch 8:
On
= Intelligent overload cut-out
Switch 9:
On
= Partial inversion following overload cut-out <disabled in the manual mode>
Switch 10:
On
= Brake
If a dip-switch is “Off” the function will not be activated, if it is “On” the function will be activated.
Some functions are only possible in specific conditions indicated in the notes between the symbols “<...>”.
