PRODUCT DESCRIPTION AND INTENDED USE
ROBUS is a line of irreversible electromechanical gearmotors designed for automating sliding gates. These gearmotors are equipped with an
electronic control unit and a connector for the SMXI or OXI radio remote control receiver (both optional). Electrical connections to external de-
vices are simplied thanks to use of the “BLUEBUS”, a technique that allows for connecting multiple devices with only 2 wires. ROBUS devices
work with electricity; in case of lack of power from the mains, it is possible to release them using a suitable key and manually move the gate or
use the optional accessory: PS124 back-up battery that allows for completing certain manoeuvres even when there is no mains power.
CAUTION! – Any use other than that specied herein or in environmental conditions other than those stated in this manual is to
be considered improper and is strictly forbidden!

APPLICATION LIMITS
The data relative to the performance of products of the ROBUS range are indicated in Chapter 12 “Technical specications” and are the only
values that allow for correctly assessing the product’s suitability for use.
The structural characteristics of ROBUS products make them suitable for use on sliding gates, according to the limits indicated in Table 2.
The actual suitability of ROBUS to automate a specic sliding gate depends on friction and on other factors, even occasional, such as the pres-
ence of frost, which may interfere with the gate’s movement.
For an actual verication it is absolutely vital to measure the force necessary to move the gate throughout its entire path and ensure that this
does not exceed half of the “nominal torque” indicated in Chapter 12 “Technical specications” (a 50% margin on the force is recommended, as
unfavourable weather conditions may cause friction to increase); furthermore, it is necessary to take into account the data indicated in Table 1
to establish the number of cycles/hour, consecutive cycles and maximum speed allowed.
Chapter 12 “Technical specications” contains the estimate of the product’s “durability”, that is, its average useful life. The durability value is
strongly inuenced by the severity of the manoeuvres, i.e. the sum of all factors that contribute to product wear. The estimate must be made by
summing up all the severity indices specied in Table 2; the total result can then be compared with the estimated durability gures in the chart.
For example, ROBUS 1000 mounted on a 650 kg gate that is 5 m long, equipped with photocells and without other intensity-enhancing ele-
ments, corresponds to a severity index of 50% (30+10+10). An estimated durability of 80,000 cycles can be inferred from the chart.
