Sentryum is the very latest Riello UPS development resulting in a third-generation transformer-free UPS, originally introduced into the
market over twenty years ago.
This ultimate solution is rated at output power factor 1 and defined as ON LINE double conversion technology in accordance with VFI-
SS-111 classification (as set out in standard IEC EN 62040-3) and it provides the very highest levels of performance such as:
 HIGH EFFICIENCY: up to 94,5% in ON LINE double conversion mode.
 ULTIMATE TECHNOLOGIES: Sentryum applies the advanced technologies such as DSP (Digital Signal Processor), dual
core microprocessor, three level inverter circuits to provide maximum protection to the critical loads, whilst maintaining
optimized energy savings.
 COMPACTNESS AND FLEXIBILITY: Sentryum is offered in two different switch configurations (single and four switches) to
suit any installation scenario and satisfy any critical power demand.
 GRAPHIC DISPLAY: Sentryum offers a multiplatform communication choice together with a colored graphic touch screen
display to easily monitor and manage the UPS.

DESCRIPTION
The purpose of a UPS is to provide a perfect power supply voltage for the devices connected to it, irrespective of whether the mains
power supply is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a stable
amplitude and frequency, regardless of any changes and/or variations occurring on the electricity grid. Whilst the UPS receives energy
from the mains supply, the DSP will ensure that the connected batteries remain charged. The DSP also monitors the amplitude and
frequency of the mains voltage, the amplitude and frequency of the voltage generated by the inverter, the load applied, the internal
temperature and the condition of the connected batteries.
The block diagrams below show each of the components that make up the UPS for both single and four switch versions.

UPS OPERATION
OPERATING MODES
The UPS can be configured for different operating modes. The following operating modes as listed below may be selected.
To configure these operating modes, the unit must be in stand-by.
ON LINE MODE
When in ON LINE mode, the system operates in ON LINE double conversion. This mode provides maximum protection for the load.
During operation the energy coming from the mains power supply (AC), is converted into a clean and stable output.
The voltage supplied to the load is a perfect sinewave, with the frequency and voltage independent of the incoming mains supply (VFI
technology). During this mode, the batteries are constantly maintained under charge.
ECO MODE
In order to optimize efficiency, in ECO MODE the load is normally powered through the bypass (any disturbances that occur within
the mains power supply can affect the load). In the event of a mains power supply failure or if the power supply is not within the pre-
set tolerances, the UPS will seamlessly switch to ON LINE operation automatically. After the power supply returns within tolerance,
the load is switched back to bypass.
FREQUENCY CONVERTER MODE
The system can be configured in this mode to generate a fixed output frequency different from the input frequency. This configuration
automatically disables the bypass line. FREQUENCY CONVERTER mode can be operated with and without connected batteries.
WARNING: Do NOT switch on the SWMB (manual bypass switch) when the UPS is in FREQUENCY CONVERTER mode.
To prevent maintenance bypass operation, the user shall keep the SWMB switch handle blocked.
OPERATING STATES
The UPS may be in a different status for each operating mode explained above. The following is a list of possible operating states.
NORMAL
When the UPS operates "normally" in the selected Operating Mode without any alarm.
In this condition the selected "Operating Mode" is displayed in light blue.
STAND-BY
This is the default status when the UPS is supplied. The UPS is powered but the system is in idle status (no power stages are active).
BATTERY WORKING
When the UPS is supplying the output with the batteries present, if the mains power supply falls outside the pre-set tolerances, for
example in case of a blackout, voltage or frequency disturbance, the system automatically switches to BATTERY OPERATING
STATUS and draws power from the batteries to support the load.
Once the mains power supply is again clean and stable, the system automatically returns back to the pre-set operational mode.
TEMPORARY BYPASS
During this operational state, the load is directly powered by the incoming mains supply, therefore, any input disturbances will directly
affect the connected load.

- 10 -
MANUAL BYPASS
The manual bypass enables the user to physically connect the UPS input directly to the output. This condition is required to perform
maintenance operations on the UPS without the need to disconnect the power from the protected load.
This is achieved by operating the Manual Bypass switch, either within the UPS (if the UPS is endowed with internal maintenance
bypass – “SW” version only) or the external manual bypass switch. In this case, follow the prescriptions contained in the “Remote
maintenance bypass" paragraph.
When the locking pad is removed from the internal manual bypass switch handle, or the external manual bypass is operated, an
auxiliary contact informs the UPS that the load is going to be transferred to manual bypass. This activates an immediate, synchronized
transition to the internal static bypass to ensure a safe closure of the manual bypass power contacts.
WARNING: Maintenance work inside the UPS is to be performed exclusively by qualified staff. There may be
voltages present within the UPS even when the input, output and battery disconnectors are open. Removal of
the UPS panels by non
-
qualified staff may result in injury to the operator and damage the equipment.
For further instructions in relation to the manual bypass function, please refer to the “Switching the system to manual bypass” chapter.
OTHER FEATURES
BACK-FEED PROTECTION
The UPS has an internal protection against back-feed. This protection acts by means of a sensing circuit which turns off the inverter
if a fault within the static switch is detected. In this condition, to avoid interrupting the supply to the connected load, the UPS switches
to bypass line.
If the bypass is not available, the connected load is switched off.
To avoid stopping the inverter, a dry contact can be configured to drive a disconnection device. This device must be installed upstream
of the bypass input to the UPS, in this case when a back-feed fault occurs, the system opens the external disconnection device (for
further information, refer to the configuration software manual).

- 11 -
