2 - GENERAL ASSEMBLY INSTRUCTIONS
2.1 – ASSEMBLY ON THE SYSTEM (GENERAL NOTES)
Before assembling the valve, accurately clean the tubing with compressed air, water or another blowing fluid to eliminate
foreign bodies, welding waste and various dirt that could damage the sealing surfaces of the valve.
ATTENTION
Assemble the valve with the direction arrow imprinted on the body in the same direction
as the tubing fluid.
Assembly is however recommended of a “Y” filter (our “FY” series) on the tubing, upstream of the valve.
Assembly of the valve can be carried out in the vertical or horizontal position, see Figure 1, page 4. You are however
advised to assemble vertically to prevent wear of the trim due to the weight and relevant rubbing.
ATTENTION
It is forbidden to weigh the valve down with foreign objects. It is compulsory to protect the
valve from external stress.

VTop Control Valves M/VTOP-M/E ed. 01 2020
WWW.CONFLOW.IT Page 4
ATTENTION
The PSL-AMS actuators can work at ambient temperatures between
– 20 / + 60 °C. The operating modes correspond to DIN EN 60034:-1:S2 for the short cycle and S4 for
the standard operations. The degree of protection is IP65, IP67 on request, in compliance with standard
EN 60529
ATTENTION
During installation of the valve, leave sufficient space to allow recover of the cover, see
Fig.2

3.1 – COMMISSIONING (GENERAL NOTES)
The valves are supplied calibrated and tested, ready to work in the conditions requested by the
client during the order
phase. Having ensured all warnings have been respected, slowly open the shut-
off valves upstream and downstream
of the valve.
THE PACKING IS MAINTENANCE-FREE.
ATTENTION
After the first working hour, check tightening of the nuts on the body unit according to the
“Nut tightening forces” table
ATTENTION Comply with the values in the “Nut tightening forces” table each time maintenance
operations are carried out.
ATTENTION
If the valve is equipped with a BELLOWS seal, never rotate the stem for any reason. A
possible wrong manoeuvre could cause torsion and breakage of the bellows.
3.2 – ELECTRIC VALVES COMMISSIONING
The PSL-AMS actuators were designed as valve electrical actuators. The actuator is assembled on the value using small
columns.
The mechanical power is generated by a 24 volt DC motor, which is controlled electronically using pulse width modulation
(PWM). The motor torque is transmitted from a series of cylindrical gears to a trapezoidal screw. The screw converts the
torque produced into an axial force with a screw drive. The vertical linear movement of the screw drive is self-
locking
and is transmitted by a connection joint to the valve stem.
When no
voltage is present or for calibration works, the actuator can be activated in emergency mode using the
handwheel (see 3.2.1), except when the PSCP fail-safe unit is used.

3.5.3.5 – FIELDBUS INTERFACE (Optional on request)
Optionally, a field bus interface can be adapted to the AMS actuator by connecting a terminal block or an external socket.
(additional assembly manual available for fieldbus AMS).
3.6 – ACCESSORIES
3.6.1 – ANTI-CONDENSATE RESISTOR (Optional on request)
The PSL-AMS actuators can be equipped with an anti-condensate resistor, when using the actuators in environments
with high temperature fluctuations or high humidity, you are advised to use an anti-condensate resistor to prevent
condensate formation
Figure 7: Resistor connection
In PSL-AMS actuators, the resistor is powered using
the actuator power supply, so there is no need to be
powered separately. To replace the resistor, connect
two cables to the terminal of the motherboard as
represented
in the image on the left.
The anti-condensate resistor is available in two different
versions (for 24 VAC/DC or 115-230 VAC). Choose the
voltage of the actuator based on the voltage.
Assembly of the resistor must be carried out in the position
indicated on the base, using the screws supplied, turn the
cable in such a manner they are not crushed by the main
cover and not touched by movement of the components
inside the actuator.
3.6.2 – ADDITIONAL LIMIT SWITCH SETTING (Optional on request)
In the PSL-AMS there are already two position feedback switches, available as a default option. They are clean
exchange contacts.
The silver-plated contacts are available (for currents between 10 Ma and 5 A, max 230 V or gold-plated contacts (for
currents between 0.1 mA and 30 Ma, max 30V). Then connect to terminals 18/19 and 20/21

Figure 9 – Cam adaptation
The cams for intervention of the switches are positioned
on the limit switch plate and can be calibrated using a
small screwdriver. Cam 1 is for the screw drive that
retracts, while cam 2 is to extend the screw drive which
extends outside the actuator.
ATTENTION
The potentiometer must not be set, non-compliance with this can damage the actuator
3.7 – STATUS DISPLAY / COMMISSIONING ELEMENTS

WWW.CONFLOW.IT Page 17
3.9 – PRE-COMMISSIONING CONTROL OPERATIONS
All the internal parameters, such as the motor torque requested, the position, the operating status and other parameters
are constantly monitored during operation of the PSL-AMS actuator, this means the position of the valve is of utmost
accuracy and that closure of the valve is always guaranteed. Changes can be read using the PSCS communication
software or using the PSC.2 local control panel (additional manual), or it can be displayed on the control cabin using
the error indication relay optional, to ensure maximum process safety.
3.9.1 – FINAL POSITION LIMITATION
The final limits of the PSL-AMS actuators can be adapted to optimal operation of the valve, using the PSCS
communication software (use a special interface cable or, alternatively, a Bluetooth connection). This will result in
various actuator behaviours. If a position is surpassed or not reachable, this can be read using the error indication relay
optional or using the PSCS communication software.
3.9.1.1 – Thrust/Torque limitation
The actuator frees the planned maximum force/torque each time it reaches the final position. If the closure point inside
the valve is modified, for example when the seal gasket is worn, the actuator will move forward based on its actuation
range, trying to reach the planned force/torque.
3.9.1.2 – Automatic positioning limitation
In normal operation, the actuator stops in the position it was in as the mechanical stop of the valve or the actuator,
during automatic commissioning. If the closure point of the valve changes, the actuator CANNOT follow this variation,
but always stops in the initially found point.
3.9.1.3 – Stroke limitation
In normal operation, the actuator stops in the point defined via manual stoppage. This position does not depend on any
mechanical stop inside the valve or the actuator.
3.10 – FINAL COMMISSIONING
The actuator is delivered in the “not commissioned” position with a green LED flashing slowly. There will be no reaction
to any input (control signal or opening/closure signal).
Based on the type of configuration of the limitations (see 3.10.1) there are two commissioning modes:
-Automatic if at least one limitation (opening or closure) is set to “torque” or “automatic positioning”.
-Manual done if both the limitations (in opening or closure) are “by position” or using the PSCS software or
using the PSC.2 control panel.

VTop Control Valves M/VTOP-M/E ed. 01 2020
