APPLICATION AND USE
MVT actuator can be used with valves push/pull (using auto stroke
calibration) or with valves with spring return using xed stroke to con-
trol hot /cool water ow rate in two/four pipes terminal units, zone
and solar plants, small reheating and dehumidifcation coils.
OPERATION
MVT is an electrical bidirectional actuator. The valve stem is activat-
ed through a synchronous motor and a gear train optimised in order
to have high performances and minimal noise ejections. The actua-
tor is equipped with a movement of limit force which is able to stop
the power supply when the force of 300N is reached. If congured as
auto calibration stroke, the software of the proportional models en-
ables the stroke calibration, so it can be used on any valve, as long
as it respects the maximum stroke limit allowed (look at the above
table).
Moreover proportional models are equipped with 3 LEDs whose op-
eration is explained in the table at page 3.
N.B.: do not use the actuator if not coupled with the valve.
POSSIBLE CONNECTIONS AND MATCHES
MVT203S, MVT403S, MVT503S are used with CONTROLLI valves VSBT./
VMBT., V.XT, 2TGA..B series and with xed stroke pressure independ-
ent control valves VSX..PB and VSXT..PB series.
Model MVT203, MVT403 and MVT503 are used with valves VSB.T,
VMB.T and 2-3TGB.B series.
Models MVT203/203S and MVT403/403S can be connected to any
controller with 3 point control signal which has the same power sup-
ply characteristics of the actuator as indicated in the paragraph
“Technical Characteristics”.

ranges 0-10Vdc, 2-10Vdc, 0-5Vdc, 6-10Vdc, 4-20mA.
MANUFACTURING CHARACTERISTICS

ications in force;
2. in case of accidental removal of the cover and/or of the con-
nector cover, make sure that power is disconnected before
working on the actuator or near it;
3. the products are maintenance free.

TECHNICAL CHARACTERISTICS
INSTALLATION AND ASSEMBLING
Models MVT203S - MVT403S - MVT503S
Before assembling the valve and the actuator, check that the set-
screw is up. If not, remember that, to mount the actuator on the
valve in the right position, you have to overcome the spring strength
of the valve itself. Screw in the ring nut M30x1,5 rmly on the valve
thread.
Models MVT203 - MVT403 - MVT503
Mount the actuator on the valve screwing in the ring nut M3x1,5
without locking it; using the manual override make the set-screw go
down until to align the actuator spindle slot with the locknut (A), se-
cure with the bolt (B) through not threaded hole in locknut (B). Direct
the actuator in the desired position and lock the ring nut M30x1,5.

ON/OFF connection with external relay
Replacement of the old proportional MVT56/57
Connect together the white and the green cable; then connect
the white cable of the new actuator in place of the white cable of
MVT56/57, the new blue cable in place of the old green cable and
the new red cable in place of the old brown cable..
If you need you can make use of the feedback signal, not available
on the old models of actuator.
Do not make electrical connection or changing operation in case
actuators are powered.
Replacement of 3-point ON/OFF MVT28/44
ATTENTION! In the 3-point ON/OFF MVT28/44 actuators to be re-
placed, the common wire is withe, while in the new actuators it is
BROWN (look at the scheme on the previous page).
RANGE SELECTION (ONLY MVT503/503S MODELS)
The actuator is supplied prearranged for 0-10V control signal and
direct action; to modify this setting, follow these instructions:
• Remove the cap and the connector (look at the following pic-
ture):
For manual override use allen key of 3 mm.
• Change the DIP switches as indicated in the following scheme:
DIP 1 ON = INV action / stroke OFF = DIR action / stroke
DIP 2 ON = 2-10 / 6-10 OFF = 0-10 / 0-5
DIP 3 ON = Range SEQ OFF = Range NORM
DIP 4 ON = xed stroke OFF = auto calibr. stroke
DIP 5 ON = 4-20mA OFF = voltage range
DIP 6 ON = Learning / stroke OFF = Running / stroke
The actuator can be coupled with push/pull valves VMB.T, VSB.T
(with MVTx03) and VX.T (with MVTx03S) using auto calibration stroke;
or to valves with spring return as VSX..PB and VSXT..PB or similar (with
MVTx03S) using xed stroke. Actuators with xed stroke (DIP 4 ON)
have only reverse action.
Through DIP 4 you can choose (on the basis of the coupled valve) if
the stroke must be xed or automatically calibrated. In case of xed
stroke (DIP 4 ON) the learning function (DIP 6) and the setting of di-
rect/reverse action (DIP 1) change their meaning: DIP 1 and 6 will be
used to choose the xed stroke value (look at the table).
Automatic stroke range selection
DIP 1 DIP 6 Valves stroke
OFF OFF 5mm
OFF ON 5,5mm
ON OFF 2,5mm
ON ON 3,5mm
Direct Reverse action
Trough DIP1 is possible to set direct or reverse action. In direct action
without control signal the actuator is fully retracted with feedback
set to 2V. With reverse action the actuator is fully exteded and the
feedback without control signal is 2 V in this position.
Through DIP 2,3 and 5 it is possible to set 5 different input ranges. If
DIP 5 is ON, the input range is set at 4-20mA and DIP 2 and 3 have no
meaning. If DIP 5 is OFF, the possible ranges are: 0-10/2-10 if DIP 3 is
OFF and 0-5/6-10 if DIP 3 is ON.
Automatic stroke calibration (valid only for DIP n. 4 in OFF)
This function helps to calibrate the maximum valve time stroke, so
that the actuator can place the valve correctly following the control
signal. If the actuator is powered on, this action can be repeated
any time DIP 6 goes from OFF to ON and DIP 4 is OFF. During normal
operation, it is possible to choose the position of DIP 6: at each start
up the stroke calibration will be carried out if DIP 6 is ON; it will be
maintained the previous stroke if DIP 6 is OFF.
Initial positioning
It will be carried out every time the actuator will be powered on and
the stroke calibration occurs. This procedure allows the actuator to
start from a dened position and then follow the control signal. That
position depends on the selection of DIP 1 (DIP 4 in OFF).
In case the DIP 4 is ON, the initial position means fully extended.
Retry function
If an unexpected stop during the stroke occurs, this function has the
aim to make it disappear. The actuator will be driven in the opposite
direction and then it will try again to reach the position.
Feedback output
The actuator is equipped with a proper output to transmit the feed-
back signal relating to the supposed actuator position. This signal
can vary from 2 to 10V.
During the “automatic stroke calibration” and “Initial positioning”
function it is xed at 2V.
