2.1) Operating limits
Chapter 8 “Technical Characteristics” provides the data needed to
determine whether ROBUS350 components are suitable for the
intended application.
In general, ROBUS350 is suitable for the automation of gates with
leaves up to 15m wide and weighing max 350kg, as shown in Tables
1 and 2.
The length of the leaf makes it possible to determine both the max-
imum number of cycles per hour and consecutive cycles, while the
weight makes it possible to determine the reduction percentage of
the cycles and the maximum speed allowed. For example, if the leaf
is 5m long it will be possible to have 10 cycles/hour and 6 consec-
utive cycles. However, if the leaf weighs 240kg, they must be
reduced to 80%, resulting in 8 cycles/hour and approximately 5 con-
secutive cycles, while the maximum speed allowed is V5: very fast.
The control unit has a limiting device which prevents the risk of over-
heating based on the load of the motor and duration of the cycles.
This device triggers when the maximum limit is exceeded.

1) Warnings
This manual contains important information regarding safety. Before you
start installing the components, it is important that you read all the infor-
mation contained herein. Store this manual safely for future use.
Due to the dangers which may arise during both the installation and use
of the ROBUS350, installation must be carried out in full respect of the
laws, provisions and rules currently in force in order to ensure maximum
safety. This chapter provides details of general warnings. Other, more
specific warnings are detailed in Chapters “3.1 Preliminary Checks” and
“5 Testing and Commissioning”.
according to the most recent European legislation, the
production of automatic doors or gates is governed by the
provisions listed in Directive 98/37/CE (Machine Directive)
and, more specifically, to provisions: EN 12445, EN 12453 and
EN 12635, which enable manufacturers to declare the pre-
sumed conformity of the product.
Please access “www.niceforyou.com” for further information, and guide-
lines for risk analysis and how to draw up the Technical Documentation.
• This manual has been especially written for use by qualified fitters.
Except for the enclosed specification “Instructions and Warnings for
Users of the ROBUS gearmotor” which is to be removed by the
installer, none of the information provided in this manual can be con-
sidered as being of interest to end users!
• Any use or operation of ROBUS350 which is not explicitly provided for
in these instructions is not permitted. Improper use may cause dam-
age and personal injury.
• Risk analysis must be carried out before starting installation, to include
the list of essential safety requisites provided for in Enclosure I of the
Machine Directive, indicating the relative solutions employed. N.B. Risk
analysis is one of the documents included in the “Technical Documen-
tation” for this automation.
• Check whether additional devices are needed to complete the automa-
tion with ROBUS350 based on the specific application requirements and
dangers present. The following risks must be considered: impact, crush-
ing, shearing, dragging, etc. as well as other general dangers.
• Do not modify any components unless such action is specified in this
manual. Operations of this type are likely to lead to malfunctions. NICE
disclaims any liability for damage resulting from modified products.
• During installation and use, ensure that solid objects or liquids do not
penetrate inside the control unit or other open devices. If necessary,
please contact the NICE customer service department; the use of
ROBUS350 in these conditions can be dangerous.
• The automation system must not be used until it has been commis-
sioned as described in chapter 5: “ Testing and commissioning”.
• The packing materials of ROBUS350 must be disposed of in compli-
ance with local regulations.
• If a fault occurs that cannot be solved using the information provided
in this manual, refer to the NICE customer service department.
• In the event that any automatic switches are tripped or fuses blown,
you must identify the fault and eliminate it before resetting the switch-
es or replacing fuses.
• Disconnect all the power supply circuits before accessing the terminals
inside the ROBUS350 cover. If the disconnection device is not identi-
fiable, post the following sign on it: “WARNING: MAINTENANCE
WORK IN PROGRESS”.
ROBUS350 is an electromechanical gearmotor used to automate sliding
gates for residential use. It has an electronic control unit and receiver for
radio control devices. The electrical connections to external devices have
been simplified through the use of “BlueBUS”, a technique by which sev-
eral devices can be connected up using just 2 wires.
ROBUS350 operates with electric power. In the event of a power failure,
the gearmotor can be released using a special key in order to move the
gate manually. Alternatively, there is the PS124 buffer battery (optional
accessory) which makes it possible to use the gate also during the event
of a power failure.
