3MAIN CHARACTERISTICS OF E-MI-AC-01F ELECTRONIC DRIVERS
4 GENERAL SPECIFICATIONS
4.1 Power supply and wiring
The power supply must be appropriately stabilized or rectified and filtered. If the power supply is
generated by a single phase rectifier use a 10000 µF/40V capacitor; if pulse voltage is generated
by a three phase rectifier, connect a 4700 µF capacitor (see ).
Connect the reference signal to the main electronic control by means of shielded and twisted
cables. Pay attention: the negative and the positive poles must not be exchanged each other.
Shield the wirings to avoid electromagnetic noise (EMC), connecting the shield to noiseless earth
(TE), see .
It is suitable to keep the driver and its cables far from any electromagnetic radiation source (like
cables where high currents flow, electric motors, transformers, relays, solenoids, portable radio-
transmitter, etc.).
The 12 VDC electric voltage supply is allowed only after evaluation of the performances required
from the proportional valves, and however after check with our technical office.
4.2 Reference signal, see .
The electronic driver is designed to receive a voltage reference signal according to the following
options:
– potentiometers mounted externally and wired according to the application diagrams.
– external reference signals generated by PLC, see .
– voltage from 0 to 10V
– current from 0 to 20 mA (only with option /RR).
4.3 Monitor signal
This voltage output signal allows to measure the current supplied to the coil, read by a voltmeter
between the test point M and pin 2 (see ).
Reading scale is 1 mV = 10 mA (ex.: if the voltage signal is 70 mV, coil current is 700 mA).
To visualize the signals use voltmeters with impedance >10 KΩ.
4.4 Set code
Basic calibration of the electronic driver is factory pre-set, according to the proportional valve it
has to be coupled with. These pre-calibrations are identified by a standard number in the model
code as follows:
1 = RZGO (KZGO) 2 = RZMO, AG*ZO, LI*ZO
3 = DHZO, DKZOR 4 = DPZO-A-*5
6 = QV*ZO(R), LEQZO
4.5 Calibrations available to the user, see , , , .
Scale
The relation between driving current and reference signal can be regulated with the Scale adjust-
ment.
Bias (dead band)
Regulation of dead band adjusts the hydraulic zero of the valve (starting position adjustment) to
the corresponding electrical zero. The electronic card is factory pre-set for the valve it is coupled
with, according to the set code (see section 4.4). An output current is obtained when the input vol-
tage is 100 mV or greater.
Ramps see , .
The internal ramp generator circuit converts a step input signal into a slowly increasing output
signal (solenoid current).
The rise/fall time of the current is set via internal potentiometer P1 up to a max. time of 10 sec. for
0-10V of reference signal. The option /RR provides dissimmetrical ramps, ramp up is set via P1
potentiometer and ramp down is set via P2.
Dither
With the /RR option the dither frequency adjust is allowed from 100 Hz to 500 Hz.

It is advisable to perform calibration procedures in the order given below:
6.1 Warning
– Never insert or remove the driver while the electronic system is powered on.
– Protect the regulator on power line with an external 2A fuse.
– Refer to to identify components mentioned in calibration procedures.
– The E-MI-AC electronic drivers are designed to work in open loop system, where the coupled
proportional valve is not required to work at its limits.
6.2 Start-up
Factory pre-set adjustments might not meet the requirements desired for the specific application.
Performances can be optimized by on-site re-adjustments of Bias, Scale and Ramps potentiome-
ters, in sequence.
– Remove the cover and connect the electronic driver according to the desired connection dia-
gram, see .
For double solenoid valves two electronic drivers type E-MI-AC-01F/7 must be used connected as
shown in .
Start-up instructions are the same for each driver.
On the first driver two cable clamps must be mounted, one for the external wirings and one to give
power and signal to the second driver which is equipped with one cable clamp and one blind
plug.
A differential voltage signal -10 V ÷ +10 V must be supplied to the first driver.
Note that the first driver will work with signal from 0 to 10V while the second driver will work with
signal from 0 to -10 V.
– The current supplied to the coil can be measured by a voltmeter connected between pins M
and 2 of the screw terminal. The reading range will be: l[mA]=10xV[mV] (for example reading
70 mV the current in the coil will be 7001mA).
Bias adjustment (dead band compensation) see , .
– Supply electrical power to the driver; supply a reference signal voltage = 0,1 VDC. Gradually
turn the P4 bias potentiometer until a movement of the controlled actuator is obtained.
– Turn in the opposite direction until the actuator is stopped.
Scale adjustment, see , .
Supply max. current reference signal; check if the current in the coil reaches the max. value desi-
red, turning P3 clockwise (see the regulation curve of the employed valve used).
Ramps see , .
Turning the ramp potentiometer clockwise, acceleration and deceleration time can be increased to
obtain the optimization of the complete system.

ELETTROMAGNETIC COMPATIBILITY
Atos electronic drivers and proportional valves are designed according to the 2004/108/CE Directive (Electromagnetic Compatibility) and according
to EN 50081-2 (Emission) and EN 50082-2 (Immunity) standards. The electromagnetic compatibility of electronic drivers is valid only for wirings
realized according to the typical electric connections shown in this technical table.
The device must be verified on the machine because the magnetic field may be different from the test conditions.
SAFETY
The electrical signals (for example reference signals, feedback and enable signal) of electronic drivers must not be used to realize safety condi-
tions of the machine. This is in accordance with the provisions of european directives (Safety requirements of fluid technology systems and com-
ponents-hydraulics, EN 982). Special attention must be payed to switch-on/switch-off of electronic drivers because they could produce uncontrol-
led movements of actuators operated by the proportional valves.

4.1 Power supply and wiring
The power supply must be appropriately stabilized or rectified and filtered. If the power supply is
generated by a single phase rectifier use a 10000 µF/40V capacitor; if pulse voltage is generated
by a three phase rectifier, connect a 4700 µF/40V capacitor (see ).
Connect the reference signal to the main electronic control by means of shielded and twisted
cables. Pay attention: the negative and the positive poles must not be exchanged each other.
Shield the wirings to avoid electromagnetic noise (EMC).
It is suitable to keep the driver and its cables far from any electromagnetic radiation source (like
cables where high currents flow, electric motors, transformers, relays, solenoids, portable radio-
transmitter, etc.). Wire the earth connection as shown in , according to CEI EN 60204-1 stan-
dards. Connect the shield of the driver to the noiseless earth terminal (TE) .
The driver is designed to correc-
tly work with 24 VDC (±20%) or 12
VDC (±20%) nominal voltage sup-
ply coupled with coils having a
resistance from 2,0 Ωto 13,4 Ω,
as shown in the side table.
4.2 Reference signal
The electronic driver is designed
to receive a voltage reference signal according to the following options:
– potentiometers mounted externally and wired according to the application diagrams, see .
– external reference signals generated by PLC, see and .
4.3 onitor signal
This voltage output signal allows to measure the current supplied to the coil, read by a voltmeter
on the front panel test points (see ). Reading scale is 1 mV = 1 mA.
To visualize the signals use voltmeters with impedance >10 K
Ω .
4.4 Set code
Basic calibration of the electronic driver is factory pre-set, according to the proportional valve it
has to be coupled with. These pre-calibrations are identified by a standard number in the model
code as follows:
1 = RZGO, KZGO 3 = DHZO, DKZOR 4 = DPZO-A-*5, DPZO-A-*7
2 = RZMO, AG*ZO, LI*ZO 3B = DHZO-A-06, DKZOR-A-16 4B = DPZO-A-*6
6 = QV*ZO(R), LIQZO
For ex-proof valves, insert an “A” before the code of adjustment.
For example, the code of adjustment for RZGA is A1 (see table E120).
The calibrations 3B and 4B allow the coupling with single solenoid valves with two external posi-
tions.
4.5 Calibrations available to the user, see ,,,.
Scale
The relation between driving current and reference signal can be regulated with the Scale adjust-
ment.
For single solenoid valves with two external operating positions, the reference signal is ± 5V (cali-
bration codes 3B and 4B).
Separate Scale potentiometers P3 and P4 for solenoids S1 and S2 enable the electronic card to be
set for different output currents, obtaining differential hydraulic operations.
Bias (dead band)
Regulation of dead band adjusts the hydraulic zero of the valve (starting position adjustment) to a
minimum signal of 200 mV. The electronic card is factory pre-set for the valve it is coupled with,
according to the set code (see section 4.4). E-BM-AC-05F/* driver for double solenoid are equip-
ped with an internal channel selector enabling the relevant channel with input reference voltage
signal greater than ± 200 mV and supplying the bias current set by front panel Bias potentiomen-
ters P1 and P2 for each solenoid.
For drivers type E-BM-AC-01F with calibration codes 3B and 4B there is not threshold and the bias
is used for the adjustment of the central position of the valve.
Ramps see , .
The internal ramp generator circuit converts a step input signal into a slowly increasing output
signal (solenoid current). The rise/fall time of the current is set via potentiometers on front panel
up to a max. time of 10 sec. for 0-100% of reference signal.
The option /RR allows up and down dissymetrical ramps for each solenoid.

3 MAIN CHARACTERISTICS OF E-ME-AC ELECTRONIC DRIVERS
4 GENERAL SPECIFICATIONS
4.1 Power supply and wirings
The power supply must be appropriately stabilized or rectified and filtered. If the power supply is
generated by a single phase rectifier, use a 10000 µF/40V capacitor; if pulse voltage is generated
by a three phase rectifier, connect a 4700 µF/40V capacitor (see ).
Connect the reference signal to the main electronic control by means of shielded and twisted
cables. Pay attention: the negative and the positive poles must not be exchanged each other.
Shield the wirings to avoid electromagnetic noise (EMC).
It is suitable to keep the driver and its cables far from any electromagnetic radiation source (like
cables where high currents flow, electric motors, transformers, relays, solenoids, portable radio-
transmitter, etc.).
Wire the earth connection as shown in , according to CEI EN 60204-1 standards.
Connect the shield of the driver to the noiseless earth terminal (TE) .
4.2 Reference signal
The electronic driver is designed to receive voltage or current reference signals according to the
following options:
– internal potentiometers mounted on board, see .
– external reference signals, see
Note that drivers designed to receive current reference (options /I) have signal values in the range
4 to 20 mA and do not have mounted on board potentiometer option.
It is possible to use current option also for double channels drivers type E-ME-AC-05F using the
reference inversion signal on contact 18c (5 ÷ 24 VDC).
4.3 Monitor signal
This voltage output signal allows to measure the current supplied to the coil, read by a voltmeter
on the front panel test points (see ). Reading scale is 1 mV = 1 mA.
To visualize the signals use voltmeters with impedance >10 K
Ω
.
4.4 Set code
Basic calibration of the electronic driver is factory preset according to the proportional valve it has
to be coupled with. These pre-calibrations are identified by a standard number in the model code
as follows:
1 = RZGO, KZGO 2 = RZMO,AG*ZO, LI*ZO
3 = DHZO, DKZOR 4 = DPZO-A-*5, DPZO-A-*7
6 = QV*ZO(R), LIQZO
For ex-proof valves, insert an “A” before the code of adjustment.
For example, the code of adjustment for RZGA is A1 (see table E120).
4.5 Calibrations/settings available to the user, see , , , , .
Scale
The Scale regulation, available on the front panel, permits to modify the relation between the refe-
rence signal and the regulated current to the solenoid.
Modifying this regulation (see , ) it is possible to fit the valve hydraulic behaviour to the effecti-
ve system conditions; in addition, the two regulations available for double solenoid valves (driver
E-ME-AC-05F) permit to set different hydraulic adjustments for positive and negative movements.
The Scale regulation is factory set at standard values depending to the proportional valve to be
controlled and it is identified by the driver set code (see 4.4)
Bias
The bias regulations, available on the front panel, permit to set the correspondence between the
electrical zero of the reference signal with the beginning of the valve’s hydraulic regulation, com-
pensating the dead band and the component’s mechanical tolerances .
Modifying this regulation (see , ) it is possible to fit the valve hydraulic behaviour to the effecti-
ve system conditions; in case of drivers for double solenoid valves (E-ME-AC-05F) the bias are
active only when the reference signal is over the threshold value of ± 100 mV.
The Scale regulation is factory set at the standard values depending to the proportional valve to be
controlled and it is identified by the driver set code (see 4.4)
Ramps
The ramp regulation, available on the front panel, permit to modify the time in which the regulated
current reaches the set value in front of a step change of the reference signal.
The ramp regulation is factory set at value close to zero and it can be increased up to 5 sec max
for a step change of the reference signal from 0% to 100%

The available ramp regulations depend to the driver version:
- in the standard version it is available a single regulation for rise/fall ramp (P7)
- in the /RR version it is possible to separately regulate the rise ramp and the fall ramp (P7 and
P17)
In the version /4R-4 it is possible to separately regulate the ramp for each of the internal reference
signals (P11-P12-P13-P14).
External ramps, see
This feature allows to regulate the ramp time by means of external potentiometers. In order to use
this capability:
- set switch SW1 in position 2
- connect one or more external potentiometers as shown (use only 2,5 MΩpotentiometers).
Internal reference signals
In the version -4, /RR-4 and /4R-4 the driver can self generate 4 different internal reference signals,
selectable by means of 4 relevant on-off commands 24 VDC, to be supplied to the contacts 22c,
24c, 24a, 22a (see scheme , ): each internal reference signal can be adjusted by means of a
relevant potentiometer available on the front panel.

7 INSTALLATION AND START-UP
It is advisable to perform calibration procedures in the order given below.
7.1 Warning
– Never insert or remove the driver while the electronic system is powered on.
– Voltages must always be measured with reference to GND (connector contact 8a or front panel
test point ).
– Refer to to identify components mentioned in calibration procedures.
7.2 Start-up
Factory pre-set adjustments might not meet the desired requirements for the specific application
and performances can be optimized by on-site re-adjustements of Bias, scale and ramps potentio-
meters, in sequence.
– Connect the electronic driver according to the desired connection diagram, , .
The current supplied to the coil can be measured by a voltmeter connected between the test
points on the front panel.
For E-ME-AC-05F the channel enabled led (L5 or L6) shows the supplied coil.
Enabling signal, see , .
The electronic driver operate when the contact 18a is supplied with an enabling signal (usually
24VDC). It could be useful in emergency conditions to inhibit the driver by zeroing this signal.
Bias adjustment (Dead band compensation), see , , .
– Supply a reference signal voltage (0VDC for E-ME-AC-01F and ± 0,1VDC for E-ME-AC-05F).
Gradually turn bias potentiometer(s) until a movement of the controlled actuator is obtained
– Turn in the opposite direction until the actuator is stopped.
Scale adjustment, see , , .
Supply max reference voltage signal (for E-ME-AC-05F driver repeat for max negative voltage) in
the specified range and turn scale potentiometer(s) until the actuator speed reaches the desired
value.
Ramps, see , .
Turning the ramp potentiometer(s) clockwise, acceleration(s) and deceleration(s) can be reduced
to obtain optimization of the complete system.

ELETTROMAGNETIC COMPATIBILITY
Atos electronic drivers and proportional valves are designed according to the 2004/108/CE Directive (Electromagnetic Compatibility) and according
to EN 50081-2 (Emission) and EN 50082-2 (Immunity) standards. The electromagnetic compatibility of electronic drivers is valid only for wirings
realized according to the typical electric connections shown in this technical table.
The device must be verified on the machine because the magnetic field may be different from the test conditions.
SAFETY
The electrical signals (for example reference signals, feedback and enable signal) of electronic drivers must not be used to realize safety condi-
tions of the machine. This is in accordance with the provisions of european directives (Safety requirements of fluid technology systems and com-
ponents-hydraulics, EN 982). Special attention must be payed to switch-on/switch-off of electronic drivers because they could produce uncontrol-
led movements of actuators operated by the proportional valves.

3 MAIN CHARACTERISTICS OF E-ME-T ELECTRONIC DRIVERS
4 GENERAL SPECIFICATIONS
4.1 Power supply and wirings
The power supply must be appropriately stabilized or rectified and filtered. If the power supply is
generated by a single phase rectifier, use a 10000µF/40V capacitor; if pulse voltage is generated
by a three phase rectifier connect a 4700µF/40V capacitor (see ).
Connect the reference signal to the main electronic control by means of shielded and twisted
cables. Pay attention: the negative and the positive poles must not be exchanged each other.
Shield the wirings to avoid electromagnetic noise (EMC).
It is suitable to keep the driver and its cables far from any electromagnetic radiation source (like
cables where high currents flow, electric motors, transformers, relays, solenoids, portable radio-
transmitter, etc.).
Wire the earth connection as shown in , according to CEI EN 60204-1 standards.
Connect the shield of the driver to the noiseless earth terminal (TE) .
4.2 Reference signal
The electronic driver is designed to receive external voltage or current reference signals accor-
ding to .
Note that drivers suitable to receive current reference (option /I) have reference signal values in
the range 4 ÷ 20 mA.
4.3 Enabling signal
The digital signal on contact 8c allows to enable (24 VDC) or disable (0 V) the driver without swit-
ching off the power supply; use this signal to cyclically inhibit the driver or in emergency condi-
tions
4.4 Set code
Basic calibration of the electronic driver is factory preset according to the proportional valve it has
to be coupled with. These pre-calibrations are identified by a standard number in the model code
as follows:
For ex-proof valves, insert an "A" in the fifth digit of the code adjustment; for example, the code
adjustment for DLHZA-T is DH04AA (see table E120).
4.5 Calibration/settings available to the user, see , , ,
Scale , see
The Scale regulation, available on the card side, permits to modify the relation between the refe-
rence signal and the position or the regulated flow.
Modifying this regulation it is possible to fit the valve hydraulic behaviour to the effective system
conditions; in addition the two regulations available for double solenoid valves (driver E-ME-T-05H)
permit to set different hydraulic adjustments for positive and negative movements.
The Scale regulation is factory set in order to control the max valve opening with 100% of the refe-
rence signal (10V)
Bias, (dead band compensation).
The bias regulations, available on the front panel (P1, P2), permit to set the correspondence
between the electrical zero of the reference signal with the beginning of the valve’s hydraulic regu-
lation, compensating the dead band and the component’s mechanical tolerances .
Modifying this regulation (see , ) it is possible to fit the valve hydraulic behaviour to the effec-
tive system conditions; in case of drivers for double solenoid valves (E-ME-T-05H) the bias are
active only when the reference signal is over the threshold value = ±200 mV.
This regulation is factory set at the standard values depending to the proportional valve to be con-
trolled and it is identified by the driver set code (see 4.4)
Ramps, see , , .
The ramp regulation, available on the front panel, permit to modify the time in which the valve rea-
ches the set opening value in front of a step change of the reference signal.
The ramp regulation is factory set at value close to zero and it can be increased up to 14 sec max
for a step change of the reference signal from 0% to 100%.

6 INSTALLATION AND START-UP
6.1 Warning:
– Do not insert or remove the driver while the electronic system is energized
– Connect the electronic driver according to the desired connection scheme (see , )
– The voltages must be always measured in reference to the GND (pin 8a of the connector)
– Refer to to identify the components mentioned in the setting procedure
– To check the reference signal and the regulated valve opening , use the test points T1 and T2
the on front panel.
– To check the correct solenoid command for positive and negative regulations, use the two led
S1 and S2 (only for drivers E-ME-T-05H)
6.2 Start-up
It is possible that the factory settings do not match the required performances for the specific
application. The system can be optimized on field, by setting in sequence the bias, scale and
ramp potentiometers.
It is advisable to perform calibration procedures in the order given below.
Bias adjustment (dead band compensation), see , , .
–Supply a reference signal voltage (0 VDC for E-ME-T-01H and ±0,2 VDC for E-ME-T-05H;
– Gradually turn potentiometer(s) (P1 for coil S1 and P2 for coil S2) until a movement of the control-
led actuator is obtained.
– Turn slowly in the opposite sense until stop is obtained.
Scale adjustment, see , ,
Set the switch A (see…..) depending to the selected range of the reference signal.
In case it is required the regulation of the valve max opening, proceed as follow:
– supply max reference signal (for E-ME-T-05H driver repeat for max negative voltage) in the
specificated range and turn counterclockwise internal scale potentiometers P5 and P6 (factory
preset to 100%) to reduce valve opening (see -C).
Gain see , (only for adjustment TH* and TK*).
Front panel potentiometer P7 could be rotated to increase sensitivity and positioning accuracy of
the axis (clockwise rotation = increase in sensitivity). Factory preset completely counterclockwise).
Ramps (see , ).
If the card is being used in a open loop system push the switch from position ramp off (standard)
to position ramp on, (see -B). Calibrate the ramp settings only if dynamic impacts and tenden-
cies towards instability persist after optimizations of the whole system. Adjust the ramp settings
using the ramp potentiometers (P3 and P4) until the phenomenon has been eliminated (Clockwise
rotation = increase in ramp time).

The two available regulations P3 and P4 permit to respectively regulate the ramp times for positive
and negative variations of the reference signal. In case of application of the driver in closed loop
systems, it is advisable to disable the ramp function: it is possible to permanently disable this func-
tion by means of a switch on the card side ( ) or temporarily, connecting the pin 6c and 6a ( )
Gain, see (only for adjustments TH* and TK*).
Pressure gain adjustment around “zero” increases sensitivity and positioning accuracy of the axis
and optimize the valve operation according to the stiffness of the system by increasing the hydrau-
lic gain of the valve around the hydraulic zero.

ELETTROMAGNETIC COMPATIBILITY
Atos electronic drivers and proportional valves are designed according to the 2004/108/CE Directive (Electromagnetic Compatibility) and according
to EN 50081-2 (Emission) and EN 50082-2 (Immunity) standards. The electromagnetic compatibility of electronic drivers is valid only for wirings
realized according to the typical electric connections shown in this technical table.
The device must be verified on the machine because the magnetic field may be different from the test conditions.
SAFETY
The electrical signals (for example reference signals, feedback and enable signal) of electronic drivers must not be used to realize safety condi-
tions of the machine. This is in accordance with the provisions of european directives (Safety requirements of fluid technology systems and com-
ponents-hydraulics, EN 982). Special attention must be payed to switch-on/switch-off of electronic drivers because they could produce uncontrol-
led movements of actuators operated by the proportional valves.

4 GENERAL SPECIFICATI NS
4.1 Power sup ply and wir ings
The power sup ply must be appro pri ate ly sta bi lized or rec ti fied and fil tered. If the power sup ply is
gen er at ed by a single phase rec ti fi er, use a 10000µF/40V capac i tor; if pulse volt age is gen er at ed
by a three phase rec ti fi er con nect a 4700µF/40V capac i tor (see ).
Connect the reference signal to the main electronic control by means of shielded and twisted
cables. Pay attention: the negative and the positive poles must not be exchanged each other.
Shield the wirings to avoid electromagnetic noise (EMC).
It is suitable to keep the driver and its cables far from any electromagnetic radiation source (like
cables where high currents flow, electric motors, transformers, relays, solenoids, portable radio-
transmitter, etc.).
Wire the earth connection as shown in , according to CEI EN 60204-1 standards.
Connect the shield of the driver to the noiseless earth terminal (TE) .
4.2 Reference sig nal
The elec tron ic driv er is designed to receive exter nal volt age or cur rent ref er ence sig nals accord -
ing to .
Note that driv ers suit able to receive cur rent ref er ence ( option /I) have sig nal val ues in the range 4
to 20mA. For single solenoid valves with two external positions (*60), the reference signal is sym-
metrical ±10 V (±5 V).
4.3 Enabling signal
The digital signal on contact 8c allows to enable (24 VDC) or disable (0 V) the driver without swit-
ching off the power supply; use this signal to cyclically inhibit the driver or in emergency conditions
4.4 Set code
Basic cal i bra tion of the elec tron ic driv er is fac to ry pre set accord ing to pro por tion al valve it has to be
cou pled with. These pre-cal i bra tions are iden ti fied by a stan dard num ber in the model code as fol low:
(*) These codes have the main stage tranducer connection different from standard (see , -
connection type B)
For ex-proof valves, insert an "A" in the fifth digit of the code adjustment; for example, the code
adjustment for DPZA-L-15* is DL15AA (see table E120).
4.5 Calibrations/set tings available to the user, see , , , .
Scale, see
The Scale regulation, available on the card side, permits to modify the relation between the refe-
rence signal and the position or the regulated flow.
Modifying this regulation it is possible to fit the valve hydraulic behaviour to the effective system
conditions; in addition the two regulations available for pos i tive and neg a tive ref er ence sig nals
permit to set different hydraulic adjustments for positive and negative movements.
The Scale regulation is factory set in order to control the max valve opening with 100% of the refe-
rence signal (10 V).

6 INSTALLATI N AND START-UP
6.1 Warning
– Do not insert or remove the driver while the electronic system is energized.
– Connect the electronic driver according to the desired connection diagram
(see , )
– The voltages must be always measured in reference to the GND (pin 16a of the connector).
– Refer to to identify components mentioned in the setting procedure.
– To check the reference signal and the regulated valve opening , use the test points T1 and T2
the on front panel.
6.2 Start-up
Factory preset adjustments may not meet the desired requirements for the specific application and
performances can be optimized by on-site re-adjustements of bias, scale and ramps potentiome-
ters, in sequence. It is advisable to perform calibration procedures in the order given below.
Bias adjustment (dead band compensation),see , , .
– Supply a reference signal voltage = 0VDC.
– Gradually turn bias potentiometer P1 until a movement of the controlled actuator is obtained.
– Turn slowly in the opposite sense, until stop is obtained.
Scale adjustment see , , .
Factory preset reference signal is ± 10V (selector in positon 1). If a 0 ÷ 5V (± 5V) reference signal
is available, set selector in position 2 ( see -A).
– Only in particular cases when a non standard reference signal is available it is possible to
adjust maximum valve opening with scale regulation proceeding as follow :
– supply max reference signal voltage (repeat for max negative voltage) in the specificated
range and turn counterclockwise internal scale potentiometers P5 and P6 (factory preset to
100%) to reduce valve opening (see -C).
Ramps (see , )
If the card is being used in a open loop system push the switch from position ramp off (standard)
to ramp on, (see -B). Calibrate the ramp settings only if dynamic impacts and tendencies
towards instability persist after optimizations of the whole system. Adjust the ramp settings using
the ramp potentiometers (P3 and P4) until the phenomenon has been eliminated (Clockwise rota-
tion = increase in ramp time).

Bias (dead band compensation)
The bias regulations, available on the front panel (P1), permit to set the correspondence between
the electrical zero of the reference signal with the beginning of the valve’s hydraulic regulation,
compensating the dead band and the component’s mechanical tolerances .
Modifying this regulation (see ) it is possible to fit the valve hydraulic behaviour to the effective
system conditions.
This regulation is factory set at the standard values depending to the proportional valve to be con-
trolled and it is identified by the driver set code (see 4.4)
Ramps, see , .
The ramp regulation, available on the front panel, permit to modify the time in which the valve rea-
ches the set opening value in front of a step change of the reference signal.
The ramp regulation is factory set at value close to zero and it can be increased up to 14 sec max
for a step change of the reference signal from 0% to 100%.
The two available regulations P3 and P4 permit to respectively regulate the ramp times for positive
and negative variations of the reference signal. In case of application of the driver in closed loop
systems, it is advisable to disable the ramp function: it is possible to permanently disable this func-
tion by means of a switch on the card side ( ) or temporarily, connecting the pin 6c and 6a ( )
