Frequently Asked Questions - VPPI Festo

What is the maximum inlet pressure for the VPPI?

The maximum inlet pressure is 15 bar.

How do I adjust the output pressure?

Turn the adjustment knob clockwise to increase pressure or counterclockwise to decrease. Lock the setting with the lock nut.

Can I use the VPPI with other fluids besides compressed air?

The VPPI is designed for compressed air and inert gases. For other fluids, consult Festo.

How do I replace the filter element?

Depressurize the system, unscrew the filter bowl, remove the old element, and insert a new one. Tighten the bowl securely.

What size is the filter element?

The filter element is available in 5 µm and 40 µm grades. Check the variant label.

How do I drain accumulated condensate?

For manual drain: pull the drain ring at the bottom of the filter bowl. For semi-automatic: the drain opens automatically when the system is depressurized.

What torque should be used for the connections?

For G1/4 connections, tighten to 15-20 Nm; for G1/2, use 30-40 Nm. Do not overtighten.

What is the operating temperature range?

The VPPI can operate between -10°C and +60°C.

Where can I find spare parts?

Spare parts such as filter elements, seals, and drain kits are available from Festo or authorized distributors. Use the model number for ordering.

How often should I perform maintenance?

Inspect the filter bowl and drain every 6 months. Replace the filter element annually or when pressure drop becomes excessive.

The three inputs are interpreted as a binary number with 3 bits.The allocation is as follows:- Setpoint value (+): DI0 or least significant bit-Setpoint value (-): DI1-Actual value output: DI2 or most significant bitThe value 000 means 0 bar and cannot be edited; the remaining 7 values can be set in ‘Input values’. There is no actual value output in this mode.

The set value is the time constant (tau) in milliseconds.Exception: with variants VPPI-...-...L...H-... exhausting to 0 bar is always run as quickly as possible. If deceleration is desired, the pressure must first be exhausted to a pressure of ≥ 1% FS.With this, a setpoint value between 0 ... 100 % of the parameterised pressure range can be specified directly via the menu. During this specification, the setpoint input is ignored.

The 'Output' menu option only appears if 'Input type' = 'Analog' has been selected.

Menu option Content	Description
‘Parameter set’ Setting	g of the control response
	‘Small’	- ‘Small’: default set for all applications. Optimised for closed volumes of 100 ml to approx. 750 ml. For larger volumes, ‘Small’ results in a softer con-trol response than ‘Large’. For applications with flow rate ‘Small’ is only suitable to a limited extent (< 100 l/min)
	‘Large’	- ‘Large’: optimised for closed volumes (≥ 750 ml on 1 m tubing, ∅ 8 mm). Faster regulation of pres-sure jumps.
	‘Flow’	- ‘Flow’: designed for flow rate applications. Softer control response due to greater hysteresis. Can also be used for closed volumes.
	‘Custom’	- ‘Custom’: individual adaptation to higher volumes or applications with longer/thinner tubing or con-strictions within the application.
‘Reference run’ ‘Start’	Appears only if ‘Paramet er set’ = ‘Custom’ → Run-ning homing.
‘Tune pres incr’ e.g. 5	200 ‘Tuning pressure increase’ appears only if ‘Parameter set’ = ‘Custom’. Setting of the tuning parameter for pressure jumps upwards.
‘Tune pres decr’ e.g.	5600 ‘Tuning pressure decrease’ appears only if ‘Parameter set’ = ‘Custom’.Setting of the tuning parameter for pressure jumps downwards.
‘Exit’ --

If the ‘Custom’ parameter set is selected, brief pressure rises up to the input pressure are possible at the working port. This is independent of any set limit values ('Pressure min'/'Pressure max'). The complete input pressure or the vacuum present at the exhaust port can be present at the working port during the regulation process and during homing.

If the application and the tuning parameters do not match, an uncontrolled response is possible (continuous oscillation, continuous maximum or minimum pressure at the working port). If the application is changed, the tuning parameters must be adjusted.

The ‘Custom’ parameter set permits individual adjustment/optimisation of the control response for an application. This adjustment enables greater pressure dynamics in the face of a constriction compared to a standard controller. This considerably reduces settling times for pressure jumps. The two required model parameters (‘Tuning increase’/‘Tuning decrease’) can be determined automatically via homing. The determined model parameters can also be adjusted manually at the port at any time. Free input of the two model parameters without homing is also possible.

Running homing

1. Connect application (connected volumes, tubing, air consumption and supply pressure must correspond to the working conditions).
2. Activate 'Custom' parameter set.
3. Select 'Reference run' menu option.

A warning appears.

1. Confirm warning with the middle button.
2. Use the arrow keys to change from the 'Cancel' menu option to the 'Start' menu option and confirm with the middle pushbutton.

Homing is started.

1. Wait until 'Successful' or 'Failed' is displayed.

Homing typically takes 30 ... 40 s.

The ‘Successful’ result indicates that homing has automatically determined tuning parameters. The ‘Failed’ result indicates that homing has failed.

Possible causes of a failed homing ('Failed'):

-Lack of supply pressure (working pressure does not reach 'Pressure max'.)

-application too fast (no bottleneck)

- extremely slow application (very large volume, very long tubing)

In these cases, the ‘Custom’ parameter set can be used by manually entering the ‘Tune pres incr’/‘Tune pres decr’ parameters.

i

Manual adjustment/free input of the tuning parameters:

The physical meaning of ‘Tune pres incr’/‘Tune pres decr’ corresponds to that of a master value for the pressurisation or exhaust process. If the tuning parameter is increased, the control response is softened. If the tuning parameter is reduced, the control response becomes more aggressive.

VPPI-...-...L...H-... 0 MPa Exhaust to 0 bar and keep the exhaust open.
> 0 MPa Active control on ‘Pressure min’.
VPPI-...-1V1H-... -0.1 MPa Valve moves to normal position.
> -0.1 MPA Active control on ‘Pressure min’.
VPPI-...-1V0H-... – Active control on ‘Pressure max’.

Tab. 18: Zero point suppression

Setpoint values < 0.7% Full scale above the minimum input value ('Input min') are interpreted as the lowest input value in order to suppress noise at the input signal → Fig. 8. Depending on the valve variant and the minimum input pressure, there may be a special response in this area → Tab. 18 Zero point suppression.

1) For variants VPPI-...-1VOH-... 0% corresponds to setpoint value 0 bar and 100% to setpoint value -1 bar.

2) The valve can be operated at an input pressure within the specified range. It must be noted here that the specified control quality is only fulfilled with a permanent supply within the operating pressure range and that the control pressure can reach the maximum available input pressure.

3) The specified control quality is only achieved if there is a permanent operating pressure supply at the valve within the specified range.

4) Active regulation is only from a setpoint value of 1% FS, below which the valve is at zero point suppression.
