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 13 ).
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 radiotransmitter, etc.). Wire the earth connection as shown in 13 , according to CEI EN 60204-1 standards. Connect the shield of the driver to the noiseless earth terminal (TE) 16 .
The driver is designed to correctly work with 24 VDC (±20%) or 12
VDC (±20%) nominal voltage supply coupled with coils having a resistance from 2,1 Ω to 3,2 Ω, as
shown in the side table.

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 9 ). Reading scale is 1 mV = 1 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 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 tech table F600).
The calibrations 3B and 4B allow the coupling with single solenoid valves with two external positions.

According to power supply value, a safety fuse is required in series to each driver:
+24 VDC - 2,5 A time lag fuse for 01F single solenoid valve and 05F double solenoid valve
5 A time lag fuse for 11F two single solenoid valves +12 VDC - 4 A time lag fuse for 01F single solenoid valve and 05F double solenoid valve
6,3 A time lag fuse for 11F two single solenoid valves 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 5 .
– external reference signals generated by PLC, see 14 and 15 .

EXTERNAL REFERENCE SIGNALS
10 , 11 .
, , Scale The relation between driving current and reference signal can be regulated with the Scale adjustment.
For single solenoid valves with two external operating positions, the reference signal is ± 5V (calibration 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 equipped 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 potentiomenters P1 and P2 for each solenoid.
E-BM-AC-01F/* and E-BM-AC-011F/* drivers for single solenoids are equipped 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 potentiomenters P1 and P2 for
each solenoid (P2 available only for E-BM-AC-011F/* drivers).
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.
