Only the opening operation can be performed from this situation.
The Stop input status is signalled by the "stop" led as illustrated in
the following table A1.
LED "STOP"
STOP input status
ON
Active (allows manoeuvre)
OFF
Inactive (blocks manoeuvre)
50%ON+50%OFF Inversion deactivated
20%ON+80%OFF Not active with the inversion deactivated (al-
lows opening only)

STEP-BY-STEP input
Each command on this input activates the open - stop - close - stop
sequence. In this mode, if the command is maintained for over 3
seconds (but less than 10), an opening manoeuvre will always be ac-
tivated; if it is maintained for over 10 seconds, a closing manoeuvre
will always be activated. This function can be useful to "synchronise"
multiple control units, commanded in parallel, in the same direction
regardless of their current status.
PHOTO input
This input is designated for the connection of photocells with NC
contacts. Only the opening manoeuvre can be performed if consent
is not given, if consent is not given during closure, an inversion is
performed.

Testing
Once the connections have been made the system can then be
tested.
!
The automation system must be tested by qualified and
experienced personnel who must establish what tests should
be conducted based on the risks involved.
Testing is the most important part of the whole automation process.
Each single component, for example the motor, safety devices, pho-
tocells, etc... may require a specific test; please follow the proce-
dures described in the operating instructions for each component.
Particular care must be given to the installation of the motor that must
have electromechanical limit switches that limit the movement be-
tween the set positions. The motor limit switches must be regulated
before testing.
The behaviour of the control unit is also connected to the program-
ming that has been performed.
Proceed as follows for the testing of the system.
In order to perform the manoeuvres, the STOP and PHOTO inputs
must give their consent, which is signalled when the related led lights.
1 Rotation direction control
Since in some cases the behaviour of the safety devices depends on
the manoeuvre direction, the correct connection of the motor must
be ensured.
- Turn the power off to the control unit and then on again after a few
seconds.
Table A1
Sensitive edge
- Give a command with the T1 button or Step-by-Step input (termi-
nal 14).
- Check that the automation moves in an opening direction, if a clos-
ing movement occurs, turn off the power supply to the control unit
and invert the wires of the motor connected to terminals 3 and 5.
2 Manoeuvre duration control
- Give an opening command and check that the power to the motor
is turned off ("open" relay = OFF) a few seconds after the manoeuvre
has been completed.
- If the working times of the control unit are unsatisfactory they must
be programmed as described in chapter 4.1 "Programming of work-
ing time".
- From a completely open position, give a closure command and
check that the power to the motor is turned off ("close" relay = OFF)
a few seconds after the manoeuvre has been completed.
3 Inputs operation control
Check that a command on the Step-by-Step input (terminal 14) per-
forms the following sequence: open-stop-close-stop (if dip-switch 1
and 2 = OFF).
4 Photocells opreation control (if connected)
- Give a closure command and check that when the beam of the
photocell is broken the control unit inverts the manoeuvre to opening.
- Give an open command and check that when the beam of the
photocell is broken the control unit continues with the opening opera-
tion.
5 Safety devices operation control (if connected) on the STOP
input
Give a closure command and check that, during the manoeuvre, the
activation of a device connected to input 12 (STOP):
- causes the immediate stop of the movement with a short inversion
Give an opening command and check that, during the manoeuvre,
the activation of a device connected to input 12 (STOP):
- causes the immediate stop of the movement with a short inversion.
6 Inversion exclusion control (if contact "S" is present):
- give a closure command and activate the inversion exclusion con-
tact "S". At this point activate the device connected to the Stop input
and check that the manoeuvre stops instantly and no inversion is
performed.
7 Impact force control (if required)
Perform the "impact force" test as required by the EN 12445 stand-
ard.
5.
Programming
The control unit allows you to program some parameters and select
some of the functions that are described below.
5.1 -
Programming of the working
time
The "Operating Time" is the maximum time in which the control unit
controls the motor until it reaches the Up or Down limit switch; the fac-
tory setting or after the memory has been cancelled is approximately
120 seconds. The operating time can be modified from a minimum
of 5 to a maximum of 120 seconds if required. The programming
procedure is performed in "self-recognition", being the measurement
of the time necessary to perform a complete manoeuvre.
The most demanding manoeuvre for the motor must be measured
(which is obliviously slower), this is normally re-winding and starting
with the motor in correspondence with a limit switch. The operating
time should ideally be programmed with a few extra seconds to that
of the time actually necessary for the manoeuvre.
