1.3 About proportional electrohydraulics

1.3.1 Electrohydraulics : hydraulics plus electronics

Atos is a leading manufacturer of electrohydraulic components & systems: the advanced technology that

integrates hydraulics and electronics to improve performances and flexibility of the modern machinery.

Electrohydraulic proportional controls modulate hydraulic parameters according to the electronic reference

signals; they are the ideal interface between hydraulic and electronic systems to perform fast, smooth and

accurate motions required by todays modern machines and plants.

Operating principle

The core of electrohydraulic controls is the proportional valve that modulates pressure or flow according to

the electronic input signal (standard: external analog signal 10 VDC).

The force of the solenoid is proportional to the reference signal, thus properly moving the spool against areturn spring to modulate hydraulic parameters

When electrical failure occurs, the spring

restores the neutral position according to the

valve configuration.

Proportional valves are available with

different neutral position to achieve the

required fail-safe configuration.

The wide range of Atos proportional valves is

available with or without integral feedback

transducer.

The sketch at side shows a proportional

directional valve with spool feedback

transducer.

1.3.2 Control loops

Open loop con trols

Control is provided through the modulation ofcurrent supplied to valve solenoid without the

effective result of the regulating loop being

verified.

R reference inputD digital driverV proportional valveM valves main stageT valves transducerL main stage transducerO actuator

Closed loop controls

Feedback transducers continuously verify the

effective result of regulation thus the closed

loop control compensates environmental

disturbances.

1.3.3 Digital proportional controls

Atos offers today one of the most advanced lines of proportional valves which allow performances close to

servovalves still maintaining the typical benefits of proportional electrohydraulics: less sensitivity, low

filtration requirements, intrinsic stability, easier servicing and lower cost.

The wide range of Atos proportional electrohydraulics is available in different executions to match the

specific application requirements and to allow simple upgrade of machine performances:

ZO-A

Open loop proportional valves to control direction/flow, pressure or flow with

pressure compensation; separate electronic drivers are required.

ZO-AES

As ZO-A execution plus digital integral electronic driver, factory preset to

ensure fine functionality, valve-to-valve interchangeability and easier set-up.

ZO-TES; ZO-LES

Closed loop proportional valves to control direction/flow or flow with pressure

compensation.

Digital integral electronic driver (factory preset) and integral spool position

transducers (1 for ZO-TES, 2 for ZO-LES) assure valve-to-valve

interchangeability, easier set-up and high response dynamics.

SP/SF/SL options add pressure/force control with alternated control selection

logic.

ZO-TERS; ZO-AERS

Closed loop proportional valves to control maximum relieved or reduced

pressure.

Digital integral electronic driver (factory preset) and integral pressure

transducer (ZO-TERS) assure valve-to-valve interchangeability, easier set-up

and high response dynamics; valves with remote pressure transducer (ZO-

AERS) allow more precise regulation and application flexibility.

ZO-PES

Variable displacement pumps with digital integral electronic driver, control inclosed loop flow and pressure; a dedicated algorithm selects which control

(flow/pressure) is active time by time.

Digital integral electronic driver (factory preset) and integral pump

displacement/pressure transducers assure pump-to-pump interchangeability,

easier set-up and high response dynamics.

ZA-**

Ex-proof executions equipped with specific solenoids certified to ATEX

94/9/CE and IECEX, available with and without integral ex-proof driver andtransducer.

1.3.4 Digital electronic drivers

Atos electronics include analog or digital drivers both in separate or integral-to-valve format.

They supply proportional valve solenoid with current to align the valve regulation and the reference signal

thus obtaining an ideal interface between hydraulic and electronic systems of modern machine and plants.

Digital electronics add variable plus to

proportional electrohydraulics:

better performances: hysteresis, response

time, linearity

software setting of hydraulic parameters:

scale, bias, ramp, non-linearity

diagnostics and computer assisted

maintenance

high immunity to electromagnetic noise

easy interfacing to fieldbus systems

1.3.5 Fieldbus systems

Atos digital electronics allow to integrate hydraulic components into machines equipped with the digital

communication system commonly known as fieldbus( i.e. CANopen, PROFIBUS DP, etc).

Up to now the connection and the control of hydraulic valves were mainly done by point-to-point analog

connections with expensive wiring and starting-up costs.

Thanks to the fieldbus systems it is possible to interface reference, monitor and diagnostic signals with

proportional valves by means of cheap 2-wire cables.

Atos digital electronics is available as standard with Serial communication interface to a notebook or

desktop PC (driver with PS execution):

option BC allows integration into CANopen fieldbus systems

option BP allows integration into PROFIBUS DP fieldbus systems

1.3.6 Axis motion controllers

Atos digital axis motion controllers are the up to date solution for the motion control in modern machines

and systems: they can be easily configured and PC programmed to best manage position, speed or force

of any electrohydraulic axis, in closed-loop by a digital proportional.

They improve motion performances, simplify the automation architecture and may be interfaced to the

machine control unit via fieldbus network.

- current to valve solenoid is switched off (operate store/restore with no active valve regulation in the

system)

- do not turn off power supply (driver parameter lose may occur)

drivers faults may compromise safety or change operating conditions, shut down the driverimmediately and notify qualified personnel

all of the relevant local and plant/machine specific regulations must be always observed

Hazardous situations may occur whenever the driver:

is not properly transported and stored

is altered or modified

is not installed, commissioned and operated by qualified persons

is not used properly

1.5.2 Personnel selection and qualification

Qualified personnel, in the sense of this document, are:

persons properly trained and authorized to install, start-up and operate the digital driver in accordance

with the established safety prescriptions and procedures

persons who, based on their technical/standards knowledge and training, are able to evaluate their

tasks, to recognize potential hazards and to carry out the correct safety measures

1.5.3 Electrical installation warning

Following recommendations on electrical installation must be always observed:

Switch-off power supply before connecting or disconnecting the driver Do not use electrical signals of the driver (e.g. reference, feedback and enable signals) for safety

purpose

Take care when switch-on/off the driver because it could produce uncontrolled movements of the

actuators operated by the driver

Always shield analog signal wirings

Use low-capacitance cables and do not use intermediate connections

Do not wire any power cables close to control electronics or command/feedback wirings

Protect the driver and other control electronics from electromagnetic noises

4 Valve Installation



4.1 General prescriptions

The following instructions are general indications and procedures for the correct installation andcommissioning of proportional valves in modern electrohydraulic systems.

Hydraulic fluid

The hydraulic fluid is used to transmit power and to provide components lubrication in hydraulic systems.

To extend system reliability select high quality fluid with high viscosity index, with antifoaming and

antioxidant additives according to the international standards: DIN 51524 and 51535

Oil viscosity rating depends on the installed pumps/motors characteristics and on the working temperature.

Use lower viscosities with low system pressure to limit pressure drops and higher viscosities for high

system pressure to limit internal leakage:

High viscosities can cause air-emulsion in the oil and therefore cavitation and noise problems in

continuous operation; start-up problems may also at ambient temperature with pumps that require

viscosities higher than 290 365 cSt.

Low viscosities decreased system efficiency and affect the dynamic lubrication.

HLP mineral oil according to DIN 51524 - part 2 are recommended (viscosity range: 15 100 mm2/sec at

40C).

Oil must be periodically controlled and normally changed every 2000 hours (see Circuit cleaning, filling and

flushing)

Fluid temperature cond itioning

A high-performance system must be properly conditioned to maintain the fluid temperature within specific

range (generically between 40 and 50C) thus obtaining a constant fluid viscosity during the operation.

The machine working cycle should start once the recommended temperature has been reached.

Fluid temperatures higher that 60C, require components with Viton seals (option /PE).

Fluid temperature must not exceed 80C.

Fluid filtration

An efficient fluid filtration prevents breakdowns of the system by protecting the components from solid

particle contamination that may affect hydraulic fluid. Cleanliness class must be equal or better than ISO

18/15, NAS 1632 class 9, by fitting in line filters of 10m and 10=75.In line pressure filters must be mounted, if possible, immediately before the proportional valve and should

be of high pressure type; clogging electrical indicator without by-pass valve are recommended.

Additional warnings have to be considered: make sure that the filters are properly sized to ensure

efficiency; one of the main sources of contamination is air exchange into the tank: proper breather filters on

the power unit tank have to be always provided; filter the fluid when filling the power unit tank (new fluids

are always contaminated) through filtration Group GL-15 or similar (see technical table S150 on

www.scoda.it).

During system working operation the frequent cleaning or replacing of filters cartridges are required.

Circuit cleaning, filling and flushingPower unit tank has to be accurately cleaned before filling it by removing all the contaminants and any

extraneous object; piping has to be cold bended and pickled.
http://www.scoda.it/http://www.scoda.it/http://www.scoda.it/

8/21/2019 e Man Ri Ters e 14

22/96



Once assembled, an accurate washing of the whole circuit (flushing) has to be performed to eliminate the

contaminants:

replace proportional valves with appropriate by-pass plates or with on-off valves

by-pass the actuator user ports by means flexible pipes

shutoff the accumulators from the other parts of the circuit

replace filters cartridge after flushing procedures

Hydraulic connections

The flexible hoses on pressure line must be shielded and secured by using proper restrain devices to

prevent damages of machine, system and injuries to the operator.

The proportional valve must be installed as close as possible to the actuator to ensure the maximum

stiffness of the circuit and the best dynamic performances.

Hydraulic return and drains lines

Return lines must be connected to the tank with low counterpressures in order to not affect the components

regulation: return lines from proportional valve to tank must be properly sized to limit counterpressures tomax 5 bar.

High flow regulation may require drain connections to realize separate piping to the tank and to maintain

proper components functionality: external drain connection port is available as standard on servocylinders

rod side, piloted directional valves and pressure reducing valves (use option /Y valves when drain port is

not available as standard).

Pilot ing pressures

Standard configuration of piloted valves is with piloting line internally connected to line pressure.

use option /E valve with external pilot connection when line pressure is less than 30 bar

For directional control valve or throttle cartridge: use option /G valve with integral pressure reducing valve when line pressure is greater than 100 bar

Air bleeds

The air in the hydraulic circuits affects the hydraulic stiffness and it causes malfunctioning: air bleeds are

provided for both proportional valves and servocylinders (cylinder rod side); in addition proper air bleed

valves should be also installed in the hydraulic system points where the air could remains trapped.

Additional warn ings at fir st start -up or af ter maintenance of the system

Unscrew all the air bleeds to allow the complete removal of air

Untight piping connections

Use a check valve on the main return line to tank maintain to avoid the self emptying of the pipes

following a long service stop

4.2 Mounting

Once removed valve packaging take care to protect valve port, connectors and cables

Do not pull valve integral transducer cables

Removed valve ports plastic protection before mounting the valve into the system

Do not touch any electric components when handling the valve

Tighten valves to the manifold without exceeding the recommended max torque (see tab.T242-1)

5 Driver Electrical connections



5.1 General prescript ions

Switch-off power supply before any wirings operation

During the system start-up, check the immunity of the reference signals from interferences and electrical

noise

Use recommended cable size: at least 1 mm2

for power supply and 0.14 mm2for other signals

It is recommended to use current signals options for distance longer than 20m (/I option for reference/

and monitor signals, and /C option for remote transducer signal)

Cable shielding and earthing

Use Shielded wirings to avoid electromagnetic noise: it is an essential part of the EMC protection from thenoises that could otherwise bring disturbance through the signal and power supply connections.

To avoid any interference, the driver cables must be separated from system power cables (connected to

transformers, electrical motors, drivers, etc.) and must be correctly shielded (see below scheme):

Connect cable shield at PLC/machine side and leave the other end (driver side) open to prevent ground

loops

If possible, connect shields to a protected earth (a noise-free connection with a different path from

safety earth and power supply ground); it is just designed to connect command signals ground, cables

shields and all other noise sensitive devices

If protected earthis not available, use the power supply ground

Verify that all the ground/earth points are equipotential otherwise position and dimension of the

connections must be checked

Earth connection of the drivers is available on the main connector; take care to the correct earthing also

the valve

In case of high noise levels, use additional shields and filters to allow the correct working of the

electronic driver

8/21/2019 e Man Ri Ters e 14

25/96



5.2.1 Power supply (pin A,B - pin 1,2)

The power supply +24 VDC(maximum range 20 32 VDC) must be appropriately stabilized or rectified and

filtered (maximum ripple 10% VPP) and must grant at least 50W for each connected driver:

apply at least a 10000 F/40 V capacitance near the driver in case of single phase rectifiers

apply at least a 4700 F/40 V capacitance near the driver in case of three phase rectifiers

2,5A safety fuse is required in series to each driver power supply.

A minimum time of 270 to 590 ms has to be considered between the driver energizing with the 24VDCpower supply and when the valve is ready to operate. During this time the current to the valve

coils is switched to zero.

5.2.2 Reference input signal (pin D,E - pin 4,5)

The driver is designed to receive one analog reference input (pin D,E differential mode input); the reference

is referred to the common mode signal zero (pin 5).

The inputs range and polarity are software selectable within the 10 VDCmaximum range; default setting is 0 10 VDC.

Option /I

The reference input signal is software selectable within 20 mA maximum range; default range is

4 20 mA and allows cable break detection (see9 and15.3).

Option /Z

The reference input signal is available in common mode (pin 4 referred to pin 5) instead of the standard

differential mode

Do not use power supply ground (V0) as reference for input signals: the absorbed current of thedrivers power stage can affect analog signal quality.

Small values of input range settings can be more affected by electrical noise.

Drivers with fieldbus interface (-BC or -BP) can be software set to receive reference values directlyby the machine control unit (fieldbus master).

In this case the analog reference input signals can be used for start-up and maintenance operations;

if not used always connect references to AGND (pin5).

5.2.3 Monitor output signal (pin F,C - pin 6,5)

The driver generates one analog output signal to monitor the actual pressure measured on the system by

the transducer integral to valve (TERS execution) or remote to valve (AERS execution); the monitor output

signal (pin F/6 referred to pin C/5) can be software set to show other signals available in the driver (e.g.

analog or fieldbus reference).

The output polarity is software selectable within 10 VDCmaximum range (see11.8).Option /I

The maximum range of monitor output signal is 4 20 mA

Do not use power supply ground (V0) as reference for input signals: the absorbed current of thedrivers power stage can affect analog signal quality.

5.2.4 Enable input signal (pin 3,2) - only for /Z opt ion

To enable the driver, supply a +24 VDCon pin 3 referred to pin 2: when the Enable signal is set to zero the

valve functioning is disabled but the driver current output stage is still active (see15.4.2, to verify this

condition with the E-SW software). This condition is useful to maintain active the serial/fieldbus

communication and the other driver functions when the hydraulic regulation of the valve must be disabled.

8/21/2019 e Man Ri Ters e 14

26/96



5.2.5 Fault output (pin 11, 2) - only for /Z opt ion

Fault output signal indicates fault conditions of the driver (solenoid short circuits/not connected, reference

signal cable broken for 4 20 mA input, valve pressure transducers cable broken, etc; fault presence

corresponds to 0 VDC, normal working corresponds to 24 VDC(pin 11 referred to pin2); see15

Fault status is not affected by the status of the Enable input signal.

5.2.6 Double Power (pin 9, 10) - only for /Z option

Separate power supply for the solenoid and for the digital electronic circuits (pin 9,10).

Cutting solenoid power supply (pin 1,2) allows to interrupt the valve functioning but keeping energized the

digital electronics thus avoiding fault conditions of the machine fieldbus controller.

Pin 2 and 10 (zero Volt) are connected together inside the electronics; see 9.1 for power suppliesrequirements.

5.3 Remote transducer connection (AERS drivers)

Remote pressure transducer installed into the systems must be directly connected to AERS driver using

the dedicated M8 connector.

The input range and polarity are software selectable within the 10 VDCmaximum range; default setting is

0 +10 VDC(see11.2).

Option /C

The transducer input range is software selectable within 20 mA maximum range; default range is

4 20 mA and allows cable break detection (see15.3).

Proper selection and installation of the remote transducer is essential to obtain the bestperformances from pressure control system.

Small values of input range settings can be more affected by electrical noise.

Refer to technical table G465 for Atos E-ATR-7 pressure transducer characteristics.

PIN standard vers ion /C opt ion (Ri = 316 )

1 TR1 remote transducer signal (0 +10 VDC) TR1 remote transducer signal (4 20 mA)

2 AGND signal zero for power supply and signal NC reserved (do not connect)

3 VT remote transducer power supply +24 VDC VT remote transducer power supply +24 VDC

4 TR2 2nd remote transducer (0 +10 VDC) - only for /SF option NC reserved (do not connect)

See table G465 for the pressure transducer characteristics and connections

8/21/2019 e Man Ri Ters e 14

27/96



5.4 Communication connection

Proper communication cables and USB adapter (see1.4.4)must be used to connect the driver to the PC

where E-SW software is installed (see QUICKSTART-** manuals for installation details).

5.4.1 Fieldbus communication connector

When the driver is connected to the main machine fieldbus network (see 1.3.5), always verify proper

wirings as described by the relevant standardization (see E-MAN-BC or E-MAN-BP manuals for further

details).

No master device must be active in a PROFIBUS DP fieldbus when using E-SW software tocommunicated with connected valve/drivers.

5.4.2 Hardware Node assignment

Driver node, unique identification in the fieldbus, can be set manually using a dip switch.

Remove the driver rear cover positioned on the programming connector side and set the node number

using the dip switch (binary coded).

Switch Switch on value Default

8ON = software setting

OFF = dip switch addressingON

7 26= 64 ON

6 25= 32

OFF

5 24= 16

4 23= 8

3 22= 4

2 21= 2

1 2 = 1

As default (switch 8 = on) the driver use the node setting stored into the driver permanent memory (tomodify see11.11,E-MAN-BC / CANopen manual or E-MAN-BP / PROFIBUS DP manual)

For BC use node settings between 1 and 127

For BP use node settings between 1 and 125 (avoid node 1 that is normally used by the master)

6 Driver parameters operation



To operate correctly E-RI-TER(AER)S drivers with the E-SW-** programming software you must always

consider how the driver and the software parameters are managed:

6.1 Parameters operation scheme

Driver Store operations (see6.2.3):

1) Store User Parameters

Driver Restore operations (see6.2.4):

2) Restore User Parameters

3) Restore Preset Parameters

Passing from OFF-LINE to ON-LINE (see6.3.1):

4) Upload Parameters5) Download Parameters

PC Setting File operations (see12):

6) Save setting file

7) Load setting file

6.2 Driver parameters

Two types of parameters are present into the driver (permanent and non-permanent) and store/restore

operations allow to define how they must be used:

6.2.1 Actual Parameters (non-permanent memory)

The driver functionality and regulation depend on its Actual Parameters that:

are automatically loaded at each power-on from the permanent memory of the driver

are lost when the driver is turned-off (non-permanent parameters)

can be displayed and modified using the E-SW software

6.2.2 Driver Preset/User/Emergency Parameters (permanent memory)

When the driver is turned-on, one of the following parameter sets is copied from this section to the Actual

Parameters (non-permanent memory) to define the driver functionalities:

PresetThis parameters set allows to start-up the driver with the factory setting

defined by Atos

User

This parameters set allows to start-up of the driver with the customized

values defined and stored by the user using E-SW software (as default

User Parameters and Preset Parameters are the same)

EmergencyThis parameters set allow to start-up the driver when Preset Parameters

and User Parameters contain corrupted data

8/21/2019 e Man Ri Ters e 14

29/96



If permanent memory is corrupted, the driver try to load alternative set:

Preset are loaded automatically in case of invalid User parameters

Emergency are loaded automatically in case of invalid Preset parameters

When invalid parameters are detected at power-on or driver restart (see9.3.4)the driver goes into

Fault condition; please contact Atos Technical Sales [email protected].

6.2.3 Store Driver Parameters

Store User This operation allows to store the driver Actual Parameters (non-

permanent) into the User Parameters (permanent) set;

At power-on the drive will automatically load the User Parameter settings

During the store/restore operations of the driver permanent memory:- power supply must be not turned off (driver parameter lose may occur) and the driver must be

disabled or in hydraulic null regulation

- current to valve solenoid is switched off, is best to operate store/restore with no active valve

regulation in the system

6.2.4 Restore Driv er Parameters

Two operations are available to select which parameters set has to be loaded into Actual parameters at

the next driver power-on:

Restore Preset

Preset Parameters will be load at next driver power-on Restore User User Parameters will be load at next driver power-on

During the restoring operations of the driver permanent memory: power supply must be not turned-off(driver parameter lose may occur) and the driver must be disabled or in null hydraulic regulation

6.3 E-SW parameters

6.3.1 E-SW Actual Parameters (non-permanent memory)

The Actual Parameters of E-SW programming software is the set of parameters displayed in the software

graphic interface.

The Actual Parameters values, depend on the communication status between the software and the driver:

ON-LINE

(communication active)

Actual Parameters of both software and driver are linked (every

change in the software is applied in the driver and vice versa)

OFF-LINE

(communication not active)Actual Parameters of the software are not linked to the driver (theycan be changed but this is not applied to the driver)

8/21/2019 e Man Ri Ters e 14

30/96



When passing from off-line to on-line mode, it is possible to select which Actual Parameters have to be

maintained between the software and the driver:

Upload Actual Parameters of the driver are maintained and are copied into

the software

Download Actual Parameters of the software are maintained and are copied

into the driver

To perform Download operation the Actual Parameters of the driver and the software must becompatible: if Driver Code parameter (see10.2) is not the same a message will display an error

condition.

During Download operation the valve/driver goes into a Disable state; after it check if thedownloaded parameter are valid. If the parameter are invalid the driver remain in Disable state and

return Invalid Download error (see9.2.3).

6.3.2 E-SW Setting Files (permanent memory)

E-SW and driver Actual Parameters can be stored or restored from the PC hard-disk as a Setting File

(see12): in any time it will be possible to restore these data into the Actual Parameter of the software and

of the driver.

Setting File can be used efficiently as a starting point when executing repetitive installation of thesame driver.

7.4 Error parameters

The Atos software implements an errors detection system in order to identify missing parameters or

eventual communication errors.

7.4.1 Miss ing parameters (OFF-LINE mode)

If corrupted file or an incomplete settings file (see 12.2) with missing

parameters is loaded, the indicator shows a missing parameter value.

Write the missing value into the indicator and save the Setting File on the PC hard disk.

The symbol is displayed for missing parameters errors.

If a Setting File missing parameter values is downloaded into the driver, the missing parameter it willoverwrite by the values present into the driver.

7.4.2 Communication errors (ON-LINE mode)

8 Main Window Communication area



In the bottom area of the Main window, it is possible to verify and change the status of communication

between the E-SW-** software and the E-RI-TER(AER)S-** drivers (see13.2).

8.1 ON-LINE/OFF-LINE mode

The indicator allows the user to verify the actual status of the communication between the E-SW

software and the connected driver (see6):

ON-LINE

(communication active)

Actual Parameters of both software and driver are linked (every

change in the software is applied in the driver and vice versa)

In this status the OFF-LINE button allows to disconnect the driver

from E-SW and to pass in OFF-LINE mode.

At start-up the E-SW software always tries to pass in ON-LINEmode if a valve/driver is properly connected.

Always use this communication mode to completely operate

and verify the connected driver.

OFF-LINE

(communication not active)

Actual Parameters of the software are not linked to the driver (they can

be changed but this is not applied to the driver)

In this status theON-LINE button allows to connect the driver from

9 Main Window Diagnostic area


9 Main Window Diagnost ic area

In the upper area of the Main window, it is

possible to verify actual working conditions (driver

status, alarms, reference and actual signals, etc)thus simplifying tuning and maintenance

operations.

It is always possible to switch on/off the

visualization of this area using the dedicated

button available in the upper-right corner of the

Main window:

Show Diagnostic area

Hide Diagnostic area

In ON-LINE mode displayed information are updated automatically.

In OFF-LINE mode displayed information remain frozen to the last status before disconnection

9.1 Working signals

This part of the Diagnostic area is dedicated to:

set and/or verify the reference signal used to control the proportional valve

verify the valve response to the commands (Feedback and PID out signals)

9.1.1 Reference Type

The control allows the user to select the source for the reference signal:

External Analog input signal (default selection) is used as reference signal; see11.1 to

modify the default input signal range

Internal Reference signal value is directly set by E-SW software (see 9.1.2); use this

setting to simply tuning or maintenance operations, and to evaluate the effect of

noise level on the analog reference signal.

Fieldbus Reference signal value is set by machine central unit using the fieldbus

communication (this selection is available only for BC and BP driver executions)

9.1.2 Reference Actual

The indicator allows the user to read the value of the reference signal

that actually selected (see9.1.1):Min -100%

Max 100%

External: the numerical value is in % of the maximum valve regulation and corresponds to the external

analog reference signal as defined by the range setting of the analog input signal (see 11.1)

Internal: the indicator becomes a control and allows to set the desired % of valve regulation

Whenever the driver power supply is switched off, the internal reference value is reset to 0%

Fieldbus: the numerical value is in % of the maximum valve regulation

9.1.3 Reference Demanded

The indicator allows the user to verify the % of the demanded valve

regulation once the actual reference signal has been elaborated by

Bias/Scale (see 11.3 and 11.4), Ramps (see 11.5) and Linearization

functions (see11.6).

Min -100%

Max 100%

9.1.4 Feedback

The indicator allows the user to verify the % of the real valve

regulation as readout by the relevant integral/remote transducer.Min 0%

Max 200%

Feedback values exceeding +100% can be displayed during dynamic conditions; in static workingconditions, reference and feedback must correspond

9.1.5 PID Out

This indicator allows the user to verify the % output of the closed loop

control action.

Min -200%

Max 200%

Control actions that reach the maximum/minimum output limits (see11.7), are possible indication ofanomalous working conditions (see9.2.1).

9.2 Driver status and warnings

This part of the Diagnostic area shows the actual valve/driver working conditions:

9.2.1 Driver status

The indicator displays in which status the driver is controlling the valve:

Active the driver is working normally

Disable the driver is disabled and no current is supplied to the solenoid.

Use enable pin (see 5.2.4)or fieldbus communication (see11.12) to

enable/disable the driver

Fault The driver is disabled due to the presence of fault conditions; no current is

supplied to the solenoid

To identify and solve the fault conditions use the Last Error description (see 9.2.1) or the moredetailed information of the Extended Diagnostic window (see15).

9.2.2 Alarm

The indicator allows the user to verify the presence of alarm conditions that has to be verified.

Alarm conditions always correspond also to the presence of a 0V on the digital output fault pin of the

main connector (see5.2.5)To identify and solve the alarm conditions use the Last Error description or the more detailedinformation of the Extended Diagnostic window (see15).

As default the driver automatically returns to Active state when no error is present (see15.3.1 Fault

Acknowledge)

9.2.3 Last Error

The indicator allows the user to identify which is the last fault/alarm condition that has occurred and

indicator to verify if the error is still present.

In case of multiple fault/alarm conditions, the worst condition is displayed first (following list -descending order); when driver is restarted (see9.3.4)or power off/on Last Error is set to No Error.

Error reactions within brackets are software settable (see11.9)

9.3 Driver Memories

This part of the Diagnostic area allow the user to verify/set which of the permanent parameter set stored

into the driver memory has been loaded at power-on into driver Actual Parameters (see6).

9.3.1 Requested

The indicator allows the user to verify which parameter set will be loaded at next power-on: use

store/restore operations (see9.3.3 and15.5.3)to change these settings.

9.3.2 Loaded

The indicator allows the user to verify which parameter set has been loaded at last power-on.

If Requested and Loaded indicators contain different value after power-on, Last error displaysInvalid parameters message and the driver is disabled (see9.2.3):

[Loaded = Preset and Requested = User] Atos factory parameters have been loaded andUser contains invalid data.

[Loaded = Emergency and Requested = User or Preset] both driver parameters contain

invalid parameters, please contact Atos service for troubleshooting

9.3.3 Store User Parameters

This button allows the user to store the driver Actual parameters into the User parameters

permanent memory (see6.1).

During parameters storing operations, power supply to the valve solenoid is switched-off: do not usethis function during system normal working.

Never switch-off the drivers power supply during storing operations: permanent parameters storedinto the driver may result invalid!

9.3.4 Driv er Restart

This button allows the user to obtain the same effect of switching off/on the driver power supply: digital

electronic is restarted and Requested parameter set is loaded.

During driver restart operations, power supply to the valve
