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 decelera-
tion points and the partial opening point.
1.
Press keys [Set] and [t] 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 ma-
noeuvre will start immediately afterwards.
5.
Wait for the control unit to close the gate.
Gate length learning mode 2 for models 250HS and 500HS
This configures:
• "Deceleration" at the 10 cm position in opening and closing;
• 100% "motor speed setup" for opening and closing (extremely fast mode, see table 8).
This mode is enabled during device recognition by holding down the [Stop] and [Close] keys for more than 8 seconds. Leds L3 and L4 now
start flashing very quickly, at which point you can release the [Stop] and [Close] keys.
If the above conditions are not satisfied, you should immediately switch off the power supply to the control unit and check the electrical connec-
tions more carefully. Other useful information can be found in the chapter on "Troubleshooting".

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 mechani-
cal 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.

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.

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 4:

Output N°1 STEP-BY-STEP command
Output N°2 "Partial opening" command
Output N°3 "Open" command
Output N°4 "Close" command

5) Testing and commissioning

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 quali-
fied and experienced personnel who must establish which

Then, at 2÷3 cm from the mechanical 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.
Please refer to paragraph "7.2 Programming" for further information
about this.

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.
