4.4) Recognizing the length of the leaf
After recognizing the devices, L3 and L4 LED’s start flashing; the control unit must recognize the length of the gate. During this stage, the
length of the leaf is measured from the closing limit switch to the opening limit switch. This measurement is required to calculate the decel-
eration points and the partial opening point.
If the above conditions are not satisfied, you should immediately switch off the power supply to the control unit and check the electrical con-
nections more carefully. For more useful information see also chapter “7.6 Troubleshooting”.

and
[Set]
and hold them down
2.
Release the keys when the manoeuvre starts (after approx. 3 s)
3.
Check the manoeuvre in progress is an opening manoeuvre. Otherwise, press the
[Stop]
key and
carefully check Paragraph “4.1 Choosing the Direction”, then repeat the process from Point 1.
4.
Wait for the control unit to open the gate until it reaches the opening limit switch; the closing manoeuvre will
start immediately afterwards.
5.
Wait for the control unit to close the gate.
4.5) Checking gate movements
On completion of the recognition of the length of the leaf, it is advis-
able to carry out a number of manoeuvres in order to check the gate
travels properly.
1.
Press the
[Open]
key to open the gate. Check that gate opening
occurs regularly, without any variations in speed. The leaf must
only slowdown and stop when it is between 70 and 50 cm from
the opening mechanical stop. Then, at 2÷3 cm from the mechan-
ical opening stop the limit switch will trigger.
2.
Press the
[Close]
key to close the gate. Check that gate closing
occurs regularly, without any variations in speed. The leaf must
only slowdown and stop when it is between 70 and 50 cm from
the closing mechanical stop. Then, at 2÷3 cm from the mechani-
cal closing stop the limit switch will trigger.
3.
During the manoeuvre, check that the flashing light flashes at a
speed of 0.5 seconds on and 0.5 seconds off. If present, also
check the flashes of the light connected to the S.C.A. terminal:
slow flashes during opening, quick flashes during closing.
4.
Open and close the gate several times to make sure that there are
no points of excessive friction and that there are no defects in the
assembly or adjustments.
5.
Check that the fastening of the ROBUS gearmotor, the rack and
the limit switch brackets are solid, stable and suitably resistant,
even if the gate accelerates or decelerates sharply.
4.6) Preset functions
The ROBUS control unit has a number of programmable functions.
These functions are set to a configuration which should satisfy most
automations. However, the functions can be altered at any time by
means of a special programming procedure.
Please refer to paragraph “7.2 Programming” for further information
about this.

4.7) Radio receiver
The “SM” radio receiver connector for SMXI or SMXIS type optional radio receivers has been provided in order to enable the user to control
ROBUS from a distance. For further information consult the radio receiver instructions manual. The association between the radio receiver
output and the command performed by ROBUS is described in table 6:

Table 6: commands with transmitter
This is the most important stage in the automation system installa-
tion procedure in order to ensure the maximum safety levels. Testing
can also be adopted as a method of periodically checking that all the
various devices in the system are functioning correctly.
Testing of the entire system must be performed by
qualified and experienced personnel who must establish
which tests to conduct on the basis of the risks involved,
and verify the compliance of the system with applicable
regulations, legislation and standards, in particular with
all the provisions of EN standard 12445 which establishes
the test methods for automation systems for gates.
