PVE Electrical Actuator

PVE Series 7 Electrical Actuator

The analog PVE Series 7 is an electro-hydraulic actuator used to control a single work section of a PVG proportional valve group. The PVE Series 7 actuator program includes variants with different performance levels and features for PVG 32/100/120/128/256.
The actuator positions the main spool in a PVG work section in order to control either the flow or the pressure of the oil distributed to/from the work function. The control signal to the actuator is an analog voltage signal, enabling the user to operate the work function remotely by means of a joystick, a controller or the similar.
The analog PVE Series 7 actuator program features five different main hydraulic principle variants (PVEO/ PVEM/PVEA/PVEH/PVES). The different hydraulic principles combined with the different solenoid valve regulation principles determine whether the actuator controls the spool proportionally according to a demand signal or ON/OFF according to a voltage signal.
The electro-hydraulic solenoid valve bridge of the actuator is available in different designs utilizing different regulation principles, depending on performance variant. The actuator positions the main spool by distributing pilot oil pressure to either side of it, pressurizing one side by pilot pressure while relieving the opposite side to tank and vice versa, as illustrated below. All proportional actuators feature a closed­loop spool control and continuous fault monitoring.

Safety in Systems

All types and brands of control valves, including proportional valves, can fail. Therefore, the necessary protection against the serious consequences of a functional failure should always be built into the system.
General safety considerations
For each application an assessment should be made for the consequences of the system in case of pressure failure and uncontrolled or blocked movements.
Warning
Because the proportional valve is used in many different applications and under different operating conditions, it is the sole responsibility of the manufacturer to ensure that all performance, safety and warning requirements of the application is met in his selection of products and complies with relevant machine specific and generic standards.
Control system example
An example of a control system using an aerial lift is shown below:
Aerial lift
This example breaks down the control system into smaller bits explaining the architecture in depth. Even though many Danfoss components are used in the PVG control system.
The function of the control system is to use the output from the PVE together other external sensors to ensure the PLUS+1 main controllers correct function of the aerial lift.

Warning
It is the responsibility of the equipment manufacturer that the control system incorporated in the machine is declared as being in conformity with the relevant machine directives.
Caution
A mix of electrical actuation and hydraulic actuation on the same valve stack is not safe. PVE and PVH are designed for different pilot pressure.
Cost-free repairs, as mentioned in Danfoss General Conditions of Sale, are carried out only at Danfoss or at service shops authorized by Danfoss.

PVEO

The PVEO actuator is a non-proportional ON/OFF control actuator with open-loop spool control primarily used to control simple ON/OFF work functions where a proportional control of speed or oil flow is not a requirement
The PVEO is available in two different performance variants, the standard PVEO and the PVEO-R with ramp.
PVEO
PVEO functionality
The standard PVEO functionality includes the simplest electric circuit of the PVE Series 7 actuator program, using a fixed 12 Vdc or 24 Vdc supply voltage or signal voltage and a simple LED circuit to control the LED light indicating Power ON/OFF.
The PVEO-DI variant includes an LVDT spool position monitor and a more advanced electric circuit with an embedded micro-controller and separate power supply to handle the Direction Indication functionality.
An energization of solenoid valve SV1 and a simultaneous de-energization of SV2 will cause the main spool to move to the right direction and vice versa. If both SV1 and SV2 are energized or de-energized simultaneously, the main spool stays locked in its neutral position.

PVEA-DI functionality
PVEA-DI functionality
The PVE functionality includes an electric circuit with a closed-loop logic. An embedded micro-controller processes the signal voltage and the LVDT feedback signal and regulates the solenoid valves accordingly.
A continuous modulation of solenoid valve NC1 and a simultaneous de-energization of NC3 causes the main spool to move to the right direction and vice versa. When the main spool is stroked to the far right, a simultaneous modulation of both NC1 and NC3 balances the main spool in its stroked position. The main spool oscillates in its stroked position at a frequency corresponding to the modulation frequency. When both NC1 and NC3 are de-energized, the main spool moves back to its neutral position by means of the main spool neutral spring and the hydraulic principle.

PVE Series 7 — Electro-Hydraulic Actuators

Fault Monitoring and Reaction

All proportional control PVE Series 7 actuators feature:
Integrated fault monitoring
•
Detecting spool stroke inconsistencies
•
Detecting internal hardware defects
•
Detecting demand signal inconsistencies
•
Fault reaction depending on the type of fault monitoring
•
Generic
‒
Specific
‒
Passive and active fault monitoring refers to whether or not the actuator is reacting on the error when it is detected.
Active fault monitoring
No matter what kind of error is detected, the solenoid valves will be disabled and the operation that the valves/spool controls will stop immediately and spool will go to neutral position. Active fault monitoring keeps a “memory” of the error, even if it is no longer registered. The active fault monitoring does not have Auto Recovery because of this “memory” and a reboot/restart will therefore be required to reactivate the solenoid valves.
With an active fault monitoring the following scenarios will take place when an error is detected/occurs:
•
The LED light will switch from green to red and the error pin output will go high
•
The solenoid valves will be disabled and the operation that the valves/spool controls will stop immediately
•
The active fault monitoring does not have Auto Recovery, so when the error is fixed/no longer is registered a reboot/restart of the PVE is required to reactivate it.

Generic Fault Reaction

Passive fault monitoring
Passive fault monitoring does not disable the solenoid valves when an error is detected. It will continue to operate despite that an error was detected. When the error no longer is registered the passive fault monitoring will “forget” the error and continue as if the error was never there.
With a passive fault monitoring the following conditions will happen when an error is detected/occurs:
The LED light will switch from green to red and the error pin output will go high
•
The solenoid valves will continue operating at the set point given at the time of the error
•
Only exception is if the error is caused by the supply voltage (UDC) being either above or below
‒
the allowed range or if the temperature measured on the internal electronics board is higher than allowed. In these cases, the solenoid valves will be disabled.
All PVE actuators with fault monitoring are triggered by the following main events:
Control Signal Monitoring
Transducer/LVDT Supervision
Supervision of Spool Position
The Control signal voltage (US) is continuously monitored. The permissible range is between 15% and 85% of the supply voltage (UDC). Outside this range the PVE will switch into an error state. A disconnected U pin (floating) is recognized as a neutral set point.
The internal LVDT wires are monitored. If the signals are interrupted or short­circuited, the PVE will switch into an error state.
The actual position must always correspond to the demanded position (US). If the actual spool position is further out from neutral than the demanded spool position or in opposite direction, the PVE will switch into an error state. Spool position closer to neutral and in same direction will not cause an error state – the situation is considered in control.

Fault Monitoring and Reaction

Fault Reaction Overview

Float Position Monitoring
Temperature Monitoring
Float position must be entered or left within a time limit. A too high delay on the 1x6 pin float PVE will cause an error state – this is relevant for the 1x6 pin PVEH-F actuators only.
When the temperature is too high the PVE LED will light constant red and solenoid valves will be disabled.
All entries have an Auto Recovery feature unless marked otherwise.

PVE Series 7 — Electro-Hydraulic Actuators
Functionality Overview

Ramp (-R)

The Ramp functionality is a rate limitation of the spool stroke, resulting in extended reaction times and in some cases a smoother control of the main spool compared to the standard PVEO variant. The Ramp functionality of a PVEO-R variant is achieved purely hydraulically by implementing two orifices working on both sides of the main spool (integrated in the actuator). The Ramp functionality of a PVEM-R variant is achieved in the regulation principle.

Functionality Overview

Quick Reaction (-Q)

The Quick Reaction functionality of the PVEM-Q variant results in shorter reaction times and a more rapid or aggressive control of the main spool compared to the standard PVEM variant. The Quick Reaction functionality of a PVEM-Q is achieved by replacing the combined orifice and check valve with a check valve in the connection to tank and changing the regulation principle.

PVE Power Save

All proportional actuator variants feature a Power Save mode, de-energizing the solenoid valve bridge. The Power Save mode is entered when the signal voltage (Us) and the LVDT spool position has been in neutral for 750 ms. As soon as the signal voltage (Us) or the LVDT spool position is out of neutral the PVE will leave its Power Save mode and re-energize the solenoid valve bridge as usual.
The Power Save mode results in increased power efficiency by reducing the current consumption of the PVE actuators in neutral position. The Power Save mode has no effect on the performance of the PVE actuator.

Special Features

Disable Mode

The PVEH-Uand PVES-U actuator variants controlled by a fixed 0-10 VDC signal voltage (US), feature the ability to enter a disable mode. This causes the counteracting force on the main spool created by the solenoid valve bridge to deactivate, when using Manual OverRide (MOR).
The disable mode is entered by sending a signal voltage (Us) of 16.2% of 10 VDC when in Power Save.
