Guard Touch is the new revolutionary controller with touch screen, researched and developed by Visa S.p.A., which will be standard supply on our gensets. From a technical and operational viewpoint, the new device is different from its predecessors, but still maintains Visa’s main characteristic: MODULARITY! Guard Touch is a versatile controller able to satisfy all the requests of the end-user.

InteliGenNTC BaseBox is a comprehensive controller for both single and multiple gen-sets operating in standby or parallel modes. The detachable modular construction allows easy installation with the potential for many different extension modules designed to suit individual customer requirements.

The ComAp InteliLiteNT AMF25 offers integrated control solutions for gen-sets operating in single standby mode. Based on the field proven InteliLite architecture, AMF25 controller fulfills every requirement from simple to complex and AMF to MRS applications – providing modem and Internet control, user configuration and complete gen-set monitoring and protection.

The DSE7320 is an Auto Mains (Utility) Failure Control Module suitable for a wide variety of single genset applications.Monitoring an extensive number of engine parameters, this modules will display warnings, shutdown and engine status information on the back-lit LCD screen, illuminated LEDs, remote PC and via SMS text alerts (with external modem).

The DSE4520 is a compact Auto Mains (Utility) Failure Control Module that has been developed to provide an outstanding range of features within a compact enclosure. 

The DSE8610 is an easy to use Synchronising Auto Start Control Module suitable for use in a multi-generator loadshare system, designed to synchronise up to 32 generators including electronic and non-electronic engines.The DSE8610 monitors the generator and indicates operational status and fault conditions, automatically starting or stopping the engine on load demand or fault condition.

The GUARD EVOLUTION device is designed and manufactured by Visa S.p.A. for the command, control and protection of the generating set.

The GUARD EVOLUTION automatic device allows automated management of a Mains failure. When the Mains fail GEVO starts the genset according to a pre-set logic...

The In-Sync device equips the Visa generating sets to satisfy the operating requirements of the most complex systems. In Sync is the best solution available on the market as it offers the most varied configuration and management options.

ATS-C is a new line of changeover switch panels developed and produced by Visa S.P.A. in accordance with IEC standards CEI EN 61439-2 (construction standard) for powers up to 125A. In their specific use with generating sets the changeover switch panels allow the changeover between mains/genset or genset/genset. The main part of the panel is represented by two interlocking contactors.

ATS-M is a new line of changeover switch panels for generating sets developed and produced by Visa S.p.A. in accordance with IEC standards CEI EN 61439-2 (construction standard) for powers up to and exceeding 125A.

Visa can count with multiple ATS configurations. Usually ATSs are enclosed in a dedicated cabinet but on demand special solutions may be developed where the ATS is included in the genset electrical cabinet in order to save space and to have a more compact and complete solution. Below the typical scenarios are described.

The 3 WAYS ATS have been designed by Visa S.p.A. in accordance with EN 61439 standards. This model is available either with contactors or with motorised switches. This model is available either with contactors or with motorised switches. Namely, this inverter has been designed for telecoms applications in order to meet the following configurations:

Visa ATS-M panels are equipped with ABB motorised disconnector switch.

The "4 ALARMS" device is an expansion module designed for use with the "Guard Evolution". When connected to the “Guard Evolution” it allows to remotely signal alarms, warnings or the status of the generating set by mean of its 4 relays. With a proper cabling it can be used to control lamps, buzzers or as an interface to supervision systems such as PLCs.

The "5IN-4OUT" card is an expansion module designed for use with the Guard Touch. The card has 5 inputs and 4 outputs. The outputs are relays with voltage free changeover contacts. Each relay is associated to a LED which indicates the status of the output. Each input can have one out of more than 30 command functions, while each output can have one out of more than 100 functions.

The "8OUT" card is an expansion module designed for use with the Guard Touch. When connected to the "Guard Touch" via the RS485 MODBus interface it allows to remotely signal alarms and warnings by mean of its 8 relays with voltage free changeover contacts. Each output can have one out of more than 100 different functions including warnings, alarms and commands.

The Guard Touch can be connected to a MODBus RTU RS485 network. The card is always a Slave, it can never be a Master. The interface used is a RS485 two-wire. Up to 32 generating sets can be monitored on a single RS485 bus. Through MODBus connections the following functions are available:
- Monitoring of electrical measurements of the engine, of the alternator and of the mains;

The J-NET ADAPTER is a converter which allows to connect one or more GUARD TOUCH boards to a PC based monitoring system. The J-NET has a USB (type B) and LAN (Ethernet) interface for the monitoring systems and a RS485 port for connection to the GUARD TOUCH. When using the USB interface, the J-NET enables a single PC to monitor and control up to 32 generating sets connected to a RS485 bus.

The 'GSM-GPRS modem' is a flexible tool designed for the remote management of the generating sets and allows to control them via multiple channels. The GSM-GPRS modem has a GPRS, USB (type B) and LAN (RJ45) interface to external monitoring systems and a RS485 port for connection to the GUARD TOUCH.

The A.SRA20 device connected to Guard Evo. allows the customer to remotely set off alarm, pre-alarm or operating mode signals for the generating set through the contacts of the 20 relays equipped with suitable cabling and system. It is possible to control lights and sounds or interface with supervision systems, such as a PLC for example, based on the requirements of the final user.

Four socket kits were designed to be installed on the rear silencer of canopies GV020 to GV200. The external measurements of the panel expressed in mm: 550 width, 435 height, 200 depth. The panel installation will extend the generating set by 200 mm Colour black RAL9005.

KITS CONTROLLED BY GUARD EVO.
INCLUDED IN THE SUPPLY: electrical and hydraulic connection between all the parts installed on board the machine.

Star

With star the start of each of the three phases is connected together. Connections are taken from the ends of the three phases to give the three phases
