FOREWORD
This aim of the handbook is to provide to the User information useful for the operation of the
NPRG 860 and NPRG 870 Automatic Synchronizer devices with the local MMI, without
configuration PC. It comes in complement from the First Handling Guide.
We advise you to read it carefully, in order to take note of the available functionalities and to
proceed to connection and power of the product in accordance with the provided
recommendations.
Locally, setting, commissioning and real time or event readings are accessible from keyboard
and displayed on the Automatic Synchronizer device.
To be fully exploited, the available functions must be parameterized and consulted with
SMARTsoft, the setting software PC, provided with the product.
Before any use, we recommend you to read the safety instructions of this User’s guide.

1. Safety instructions
For your safety, we recommend you to read the following information carefully. They have
the aim of specifying the precautions essential to the good installation and the correct
operation of the products.
1.1 Documentation
Following documentations are available for the products of range NP800:
General presentation of NP800 Range.
Application Guide of NP800 Range.
User’s Guide of the SMARTsoft Setting Software
User’s Guide (by type of product)
First Handling Guide (by type of product)
Diagram for each relays.
We advise you to read them before any handling.
1.2 Connection of the NP800 range
The terminal blocks of the Automatic Synchronizer are studied to ensure the safety of the
people during the operation of the products.
During installation, commissioning or maintenance, they can however present high voltages
and possibly a thermal heating. Consequently, the following precautions must be respected:
Connection of the terminal blocks at installation must be carried out after having
ensured of the absence of any voltage
Their access during operation must be carried out through adequate means ensuring
as well electric as thermal insulation
The connection of the earth at the back of the relays must imperatively be done with
mean of a 2.5 mm² wire.
Before powering the Automatic Synchronizer, it will be necessary to check in particular:
The value of the voltage rating of the auxiliary supply and its polarization
The good realization of connections
Integrity of the connection to the earth.
1.3 On load withdrawal
It is formally misadvised to withdraw the connectors under voltage or on load.
1.4 Removal and destruction
The Automatic Synchronizer should in no case be opened by the User. During their removal,
they must be completely isolated from any external polarity and capacitors must be
discharged by connecting their external terminals to the earth.
The destruction of the Automatic Synchronizer will have to be carried out in accordance with
the legislation in force, in particular in compliance with the environment and safety
requirements.

When one of the three conditions is filled and that stability is correct, the following message
appears on the two lines of the display:
UG°:ok (ΔU ok) else U!
UG°:ok (ΔF ok) else G!
UG°:00 (Δφ ok) else °+50 for gap +50°
St : (Stability ok) else S!
Uok Gok St (the first two conditions are met with a correct stability)
°00 (gap of correct phase)
Indication of the measurement mode INT or EXT

The Automatic Synchronizer device with his initial configuration, NPRG860, provides: 3
output relays + 1 watchdog relay. In extended version, NPRG870 version, this one provides
7 output relays + 1 watchdog relay.
The assignment cannot be modified.
WD: Watchdog
Relay A: +f order
Relay B: - f order
Relay C: Paralleling order
The following relays are available only with the NPRG 870 version only.
Relay D: Generator selection fault
Relay E: +U order
Relay F: -U order
Relay G: Paralleling of dead bus line enable
When powering the relay with the auxiliary supply, the displays below can appear. The
advised actions allow reaching the beginning of the setting of the Automatic synchronizer.
