4Safety information
4.1 General
The Vigilant monitoring system is designed to meet the safety regulations. However, its safety can be
at risk if the equipment is installed or used by unqualified staff, used improperly, or not inspected
and maintained.
Installation, operation, and maintenance of the system should
only be undertaken by specialist personnel and following the
safety and accident prevention regulations.
Repairs of the system should only be undertaken by SDT, or by
personnel authorized by SDT.
It must be ensured during operation, installation, or maintenance that all safety instructions have
been followed, along with all safety regulations that might apply.
4.2 Installation and wiring
Before starting the installation, work read the instructions delivered with the equipment. Stop the
installation work if you have any doubt and contact your distributor or SDT for assistance.
Be sure that main power is off and will stay off until the
installation work ends. Check that the equipment is voltage-
free by using a voltage tester. You should always install the
equipment isolated from the power supply or any electrical
power source.
Inspect all components to be installed. Check they are all in
good condition and do not present any damage. Reject
components that contribute any damage.
Check that all materials to be installed are compliance with EU
directives or international regulation concerning electrical
safety.
Foreign materials, like protective material used for transportation, dirt, or any other pollutant, must
be removed before installing the equipment.
Choose installation tools that are safe and suitable for the working environment.
Check all components have been professionally installed and connected. Wiring should follow these
requirements:
•Use 17 to 22 AWG copper conductors (AWG 20 recommended) for wiring the equipment. For
a ground terminal an AWG 17 size conductor is suggested.
•Use a minimum size of AWG 17 for grounding the DIN rail.
•Solid or stranded conductors are allowed.
•Ensure all cables and terminals are in proper condition and do not show any visual defect.
•Cables should not be twisted or allowed to run over sharp edges.

Vigilant User Manual

The equipment must connect to ground using the screw terminal marked with the earth IEC symbol
and provided in one of the connectors. Make sure that the protective earth conductor is connected
correctly to that ground terminal. Additionally, the equipment makes a chassis ground connection
through the DIN rail, which in turn must relate to the ground.
Make sure to use DIN rail with good conductive properties. It is
recommended to use steel DIN rails. Do not use DIN rails made
of plastic or poor conductor materials. Ensure the DIN rail is not
oxidized or corroded or presents any other defects resulting
from improper chassis grounding.
For metallic enclosures it is a highly recommended enclosure
that is connected to ground to avoid potential EMI or noise
interferences going into the equipment.
Failure to ensure a correct ground connection may result in an
electrical risk and cause the equipment to work in an
unfavorable operating condition.
See Electrical installation for the wiring details about how to connect the power supply and
grounding on the equipment.
4.6 Batteries and battery charging
The Vigilant has a rechargeable internal lithium-polymer battery as its auxiliary power supply. The
integrated battery recharges automatically when the device is connected to the main DC power
adaptor. The equipment battery is assembled inside, under a cap located in the back of the
instrument and closed by screws. See chapter dedicated to Replacement of internal components to
read more about the battery and its possible replacement.
The system has been designed for a specific battery model,
which also includes an integrated electrical protection system.

5System Description
5.1 Introduction
Vigilant Online Machinery Supervisor is a state-of-the-art monitoring system whose purpose is to
provide users with the measurements required for assessing the condition of the machinery or
equipment being monitored.
Vigilant is a smart solution for protection, condition monitoring and failure mode identification of
critical machinery. It can work as a standalone system, it does not require a permanent connection to
a computer or software, while still measuring and protecting the equipment, storing data or even
communicating scalar measurements to other systems via Modbus-TCP protocol.
It accepts both static and dynamic signals from most kinds of sensors typically used for condition-
based monitoring: vibration, temperature, ultrasound, thermal images, video, speed, motor current,
oil condition parameters, load, process, etc.
Vigilant is a small size and low consumption hardware device. It integrates a web server that provides
an interface for users through a web browser, without installing any software. With that web
interface the user can configure and access all data being measured in the unit, along with all the
types of graphs required for its visualization and analysis (trends, spectrum, waveform, parameter
tables, etc.). It also provides data storage with enough capacity for enabling monitoring of extended
periods. The advantages of this new technology are:
•It eliminates the need for a local server, and therefore its maintenance is also eliminated.
•It can be connected directly to the Internet, so the measurements can be accessed from any
part of the world using a computer or device connected to the Internet and a web browser.
•It is not required to pay for software licenses to access the data.
•Access is not limited to several computers or devices.
•Obsolescence is avoided by applying automatic updates.
•It is very intuitive, accelerating the learning curve and allowing users to access all the start
functionality.
•Reduce the initial investment by simplifying the monitoring system.
•The system includes 8 analog inputs with simultaneous high-frequency sampling. V8-L
version adds 4 additional low-frequency sampling analog inputs.
•Vigilant also includes bidirectional communication via Modbus-TCP protocol for its
integration with external systems.

6Design
6.1 External appearance
In the front and back sides of the Vigilant several pluggable terminal blocks allow connecting wires
both for sensor signals and power supply. All these terminals are to be connected only to SELV-LPS
(safety low-voltage) lines.
Vigilant also has an RJ45 jack port on the left part of the case’s front for Ethernet communications
(100Base-TX). The Ethernet port is to be connected only to indoor routed networks.
Next to the RJ45 port, a USB connector (A-type) plugs a slave device. This port is not implemented
yet and cannot be used.
On the top of the instrument, several LED indicators give information about the device’s state and
the signals being read.
The following chapters contain some images with more detailed information about the Vigilant and
its hardware.

8Installation
8.1 Mechanical assembly
The Vigilant system was not designed as an “enclosed type”. That means that it generally requires
installation into an external enclosure prepared for the application site’s environmental conditions.
The equipment includes an accessory to be mounted on standard DIN rail (35 mm rail). Using the
accessory installed at the back of the casing, the equipment can be arranged on a DIN rail fastened to
the mounting panel of the enclosure.
On the picture below it can be seen the backside of the Vigilant, where this DIN rail accessory is
shown:
The following table describes the steps for assembling or removing the Vigilant from the DIN rail.
To fasten the Vigilant onto the DIN rail, align it with the DIN rail connector, press firmly on top and
push the lower end into position.
To remove the Vigilant press firmly on top and pull the lower end away from the DIN rail.
The Vigilant includes a forced ventilation system that regulates
its temperature. However, to guarantee its proper cooling, the
enclosure’s temperature must be kept within the allowable
limits (see Specifications). It must consider the heating caused
