APPLICATION AND USE

MVER is a flexible electro-mechanical actuator equipped with an
electronic fail safe function for the control of two-way and three-way
globe valves in:
• Heating and cooling systems;
• Air Handling Units;
• District heating plants;
• Industrial temperature control systems.
The actuator is endowed with an electronic emergency return fun-
ction which operates through the use of ultracapacitors whose life
is about 10 years if the actuator operates within the operation limits
declared in this data sheet.
The emergency position (retracted or extended stem) is set through
the use of a jumper which can be easily reached (look at paragraph
"DIP switches and jumper settings").
The actuator is supplied with totally discharged ultracapacitors and
at its first start a pre-charge phase of about130s will be necessary.
During this phase all the functions of the actuator are inhibited and
the charge status of the ultracapacitors is signalled through 2 LEDs
(look at paragraph "Standard LEDs behaviour").
MVER can be controlled either by a proportional (modulating) signal
or by an increase/decrease (floating) signal.
It is easy to mount and connect the actuator. Direct mounting is pos-
sible to any CONTROLLI flanged valve. Linkage kits are available
for CONTROLLI threaded valves as well as for valves of other ma-
nufacturers. The actuator has a fine resolution (500 steps on the full
stroke range) for accurate fluid control and it is able to self-calibrate
on a different stroke without the need of any user action (this fun-
ction is DIP switch selectable on the field).
MVER has intelligent behavior and alarm functionality in case of
unexpected operation, feedback of alarms to the user is provided
by LEDs (GREEN and RED) on the upper control board.
N.B.: do not use the actuator if not coupled with its relating valve.

OPERATION

The actuator is endowed with an electronic emergency fail safe fun-
ction which, in case of power failure, allows to close (or to open) the
valve and to go back to the set position through the jumper.
The actuator commutes the control signal (modulating or 3-point flo-
ating) from the controller into a valve position. A modern brushless
DC motor in the actuator drives a gear train and a worm gear –
screw jack mechanism convert the motor revolutions into accurate
and repeatable linear movements.
Control Signal
MVER can be controlled by one of 2 main control types.
• 3-point floating ;
• Modulating (proportional) signal with filed selectable ran-
ge (e.g., 0-10Vdc, 2-10Vdc, 0-5/2-6Vdc, 5-10/6-10Vdc and
4-20mA).
Manual Override
There is a manual operation handle on the actuator. When it is lowe-
red (manual override ON), the power supply to the motor power sta-
ge circuitry is cut and the motor stops. The actuator can be opera-
ted manually and the valve positioned accordingly.
The manual override lever stays in position until it is raised again, then
board and motor will be powered again. At the end of this operation
the actuator moves to initial position (on the basis of DIP 1 setting)
then it follows the control signal. When the manual override is enga-
ged the GREEN and the RED LED on the lower electronic board are
ON.
Manual operation handle can also be used to modify any DIP switch
setting or as re-set function after any alarm occurrence.
The actuator is supplied with the manual override lowered (ON). It
is not necessary to remove power supply to modify DIP switches set-
ting.
