General Information
PVED-CC4 introduction
The Danfoss PVED-CC4 is a digital (D) controlled PVE-Series 7 actuator for PVG 32 and PVG 100. The PVEDCC4 follows the modular Danfoss concept.
CC is an abbreviation for CAN bus Communication. The communication is compliant to the SAE J1939
protocol and the ISOBUS standard for flow control.
The PVED-CC4 has proven its worth and is used in various types of mobile hydraulic applications with
high demands to precision and controllability.
The PVED-CC4 can be controlled by a Danfoss PLUS+1® GUIDE application or other devices capable of
using communication as defined in this Technical Information.
Customizing of the PVED-CC4 is done by parameter setting. Settings can be made by the PLUS+1® Service

With the PVED-CC4 a hydraulic application with PVG can have up to sixteen individually controlled valves
on one CAN bus. Giving full control and feedback for every work function.
The oil flow out of the work function (A- or B-port) can be controlled by a combination of the following:
PVED-CC4 controlling the spool position using pilot oil pressure.
•
A handle (PVM) in mechanical interface with the spool.
•
PVG 32 structural lay-out with naming
A A-port
B B-port
C PVS end plate
D PVB basic module
E Connector pin
T Tank port
P Pump supply port
The PVED-CC4 uses the ISOBUS and J1939 protocol, thus following the standard protocols. The physical
layer for CAN communication applies to ISO 11898-2 high speed CAN.
The spool is controlled by flow commands in steps of 0.4% or by spool position with 250 positions in each
direction and dead band compensation. Monitored manual operation is possible.
The embedded system also monitors safety. Spool position, communication, electronics, memory,
calculations and temperature are continuously evaluated and all violations are broadcasted and logged.

General Information
PVG functionality
Option mounted PVG with PVSK, PVED-CC4 with AMP connector
This chapter will give an overview of the PVG and its functionality.
Valve section with naming - standard mounted - seen from PVP
The PVG valve distributes oil from pump flow to a particular work function in the application via a specific
valve section. This is done by moving the spool (PVBS).
Depending on the choice of components the oil work flow enters the PVG through the PVP (proportional
valve pump side module) or the PVSK (proportional valve end plate for crane) and enters the PVB
(proportional valve basic module) via the P gallery and leaves through the T gallery.
In the figure above you see a valve section seen from PVP towards PVSK with the PVM and PVE standard
mounted. PVM and PVE can in general be interchanged, that is called option mounted.
With the spool in neutral, where it is kept by the neutral spring, the connection to the application via
ports is blocked.
Moving the spool towards the PVE, as in figure 4, opens a connection between P and A and also between
B and T. This is done by either pushing the PVM or sending a retract command to PVED. The PVED move
the spool by letting Pilot Oil Pressure (Pp) push on the right end of the PVBS and releasing pressure from
the left end. For details on PVG please see relevant technical information.
Any PVG with PVM can be operated by PVM alone, independent of a power supply. Any PVG with PVEDCC4 can monitor PVBS if power and communication conditions are present.

PVED-CC4 functionality
This section main focus is to provide a brief overview before heading into the following technical
chapters. Understanding this section is regarded as a minimum in order to understand the use of the
actuator.
Before any installation and use of the PVED-CC4 it is highly recommended that the user understands the
technical chapters as well.
The PVED-CC4 features four different modes of operation: Full Operational mode, Hand Operational
mode, Emergency mode and Fault mode.
Prior to operation the PVED-CC4 performs a Power On Self Test (POST) in order to validate the state of
electronics, settings and software.
If the PVED-CC4 recognizes violations of standard operation it will immediately give a detailed feedback
on this event. If the violation is regarded as possibly dangerous the PVED-CC4 will enter fault mode.
The PVED-CC4 is a mechatronic device, meaning mechanics, hydraulics, electronics and micro-controller
interacting with external systems.
The illustration below gives an overview of the actuator tasks. On the left side is external system
interaction on the right side internal tasks.

Housing
The housing of this product protects the internal parts from the environment and gives by design the
optimal interface to cabling, Pilot pressure and spool.
PVED-CC4 Cable kit
The cabling is one of the great advantages for CAN systems. It reduces the number of cables and gives a
simpler system overview.
All units (ECU e.g. PVED) are connected by the CAN bus, a CAN high and a CAN low wire which are
terminated at the ends. Power and ground wires can with respect to maximum current consumption
follow the bus wires.
The bus can either be made as a daisy chain, where the stub from bus to ECU is inside the PVED

Both solutions have advantages and disadvantages. Danfoss supports the daisy chain solution with
cables but the PVED-CC4 could easily be used with the back bone solution.
PVED-CC4 mounting
The Danfoss PVG concept is based on parts interchangeability. This is also valid for the PVED-CC4 and
makes field retrofitting possible. PVED can be mounted on both ends of PVB.

Hydraulic subsystem
Warning
Deviation from recommended torque can harm performance and module.
Linear Variable Differential Transducer (LVDT)
The Linear Variable Differential Transducer (LVDT) or position sensor is the interface between the
mechanical system (spool) and the electronic system.
Warning
The LVDT must never be mechanically adjusted, bent, damaged or partially blocked as this will lead to
incorrect information on spool position.
Spool neutral spring
The PVBS neutral spring is an important safety component as it keeps or moves the PVBS in blocked
position when solenoid valves are disabled. The spring will keep the A and B port.
The hydraulic subsystem is used for moving the spool and thereby opening the valve for work flow.
Pilot oil diagram
The heart of the hydraulic subsystem is the solenoid valve bridge. It consist of four poppet valves, the two
upper ones are normally closed (NC-S) with a small bleed, the two lower ones are normally open (NO).
A continuous modulation of solenoid valves NC1 and NO4 together with a simultaneous energization of
NO2 and 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 energization of both NO2 and NO4 and
de-energization of both NC1 and NC3 balances the main spool in its stroked position. An emergency stop
activated when the spool is stroked will cause all solenoid valves to de-energize causing the main spool
to move back to its neutral position by means of the main spool neutral spring and the hydraulic
principle.
The Pp will work against the PVBS neutral spring when the spool is moved out of blocked (neutral) and
together with the spring when going in blocked. This combined with a larger opening in the NO than in
the NC-S will give a faster movement towards blocked than out of blocked.
Warning
Obstacles for the Pp can have direct influence on spool control. Reduced pilot pressure will limit spool
control. Too high Pp can harm the system.

Power On Self Test (POST)
When power is applied to the PVED-CC4 it will initialize components and validate component states and
parameter settings. If test is passed the PVED will enter Full Operational mode otherwise it will enter Fault
mode. In both cases it will, if possible, make itself known to the network by an address claim followed by
if needed a fault message (DM1) and then Auxiliary Valve Estimated Flow message (AVEF).

Settings and system data
The PVED-CC4 offers a number of settings for both spool control, fault monitoring and general system
settings. A number of system information parameters are available via the service tool. Details are
available in the data section of this Technical Information.
PVED-CC4 Process data
Process data can be considered as user or situation specific values. They are the runtime settings Ramp
timing, scaling of set point, variation of progressivity and port inversion and can be changed during
operation by an ISOBUS message.
OEM data
OEM data can be considered as application or system specific values. They are a number of safety
settings, performance settings and the module communication identifier. Also a set of fall back values for
the process data are stored as OEM data.
Spool data
Spool data are parameters used for linearization of the spool. These parameters gives relation between
spool position and flow command in order to comply with the ISOBUS standard of 0.4% flow change for
each step of the Auxiliary Valve Command (AVC).
General part details
Information like part number, production date, software identification and Name field are also available.

PVED-CC4 safety description
Definition
Concept
For a general description on Safety in Application please see PVG 32 Technical Information
BC152886483664.
The Danfoss definition of safe state transition by fault: Depower solenoids and release spool to neutral
spring. PVBS to be forced to blocked position (neutral) by neutral spring.
The PVED-CC4 has Active Fault Reaction, meaning the solenoids are disabled on fault. Less flow than
commanded is not regarded as dangerous by the PVED.
The PVED-CC4 safety concept is based on two elements:
POST – Power On Self Test
•
Runtime fault monitoring and reaction
•
The basic elements for product safety are:
Continuous module self monitoring
•
Fault recognition and reaction
•
Fault reporting and recording
•
Fault recovery
•
POST–Power On Self Test
When powered the PVED evaluates settings, circuit, sensors and spool interface .
Passing of the POST is a precondition for entering Full Operational Mode.
PVED-CC4 runtime fault monitoring
After power on set up and POST the runtime fault monitoring takes over. Every time the uCSM enters the
safety task a number of feedbacks are evaluated. In parallel the internal handshake between
microcontroller and watch dog is running. The faults are categorized by origin and severity level

PVED-CC4 safety description
PVED-CC4 fault Reaction
Fault severity level
Warning. A changes of settings was attempted but could not be followed
•
Severe. Based on the present state actuation cannot be continued. This is for fault types permanent
•
and temporary.
In case of recognized unintended behavior the PVED-CC4 can react in three ways.
For some events the reaction is at first occurrence for others after a threshold is passed.
By multiple faults the most severe has priority and the PVED-CC4 will stay in fault mode until recovered
from all faults.
Recorded and reported solenoid disabling
Used by severity level Severe and solenoids are disabled.
If the event is regarded safety or performance threatening the solenoids are disabled (spool forced back
to blocked), a distress messages is broadcasted on the CAN bus at occurrence and for as long as present
and a record is made in the error log.
PVED-CC4 fault recovery
Recorded and reported ignorance
Used by severity level Warning and solenoids are not disabled.
A distress messages is broadcasted on the CAN bus at occurrence and as long as present and a record is
made in the error log.
Unrecorded reaction
By missing handshake from microcontroller the Watch dog disables the solenoids and the CAN bus
interface.
For events of severity level Severe there are one of two ways of recovery.
Reboot
The event is regarded as system threatening and a system reconfiguration and reevaluation is required.
Resume
The event is regarded as performance/safety threatening but not system threatening. When the fault
trigger disappears transmission of two AVC Blocked reactivates the PVED.
For events with severity level Warning no recovery needed. The operator might though need to send a
valid setting changes to get a desired performance.

Parameter description
Parameters in the PVED-CC4 are organized in a hierarchy with active parameters as most important and
back up parameters as less important. Yellow framing indicates high accessibility, red low and purple
read only. Changing parameters in one position will not necessarily change parameters at other
positions. For example ramp changed as process data will change performance until next reboot, ramp
value changed and stored as process data will have effect until next restore OEM defaults. Changing
ramp in OEM data will only have effect for performance if restore OEM data is performed in Process Data

Safety parameters
For some faults a threshold for recognition can be set. That is done by the General Timeout (GTO), the
Float Time Out (FTO) and the auxiliary valve Command Time Out (CTO). The fault recovery conditions can
be altered for a number of faults, named monitoring. Also the Power Save setting has influence on
system safety and not only power consumption.
Behavior parameters
A number of parameters have a direct influence on how the PVED perform on a flow command. These
parameters are referred to as process data. These are ramping, scaling, progressivity and port inverting.
Also a minimum flow before entering float can be defined. All these parameters can be changed by a
single CAN message.

Technical data
Spool curve overview
The spool curve defines relation between PFC in AVC and actual spool position in PVB. See also section
Communication. J1939 defines an increment of the PFC by one gives a flow growth of 0.4% of max spool
flow. Customization of the spool curve changes this ratio.
Vertical is the flow command horizontal is the spool position.
•
Vertical 1 refers to PFC 1 and horizontal 52 is PVBS (7 mm/250)*52 = 1.46 mm out of neutral.
•
Vertical 250 is equal to flow 100%.
•
Float spools
For float spools Spool type Float opens menu to defines float direction by standard mounting. Float A is
float in retract. Maximum flow (vertical 250) is at horizontal 171 (4.8 mm) and for PVBZ at horizontal 196
(5.5 mm).
Vertical 1 and vertical 250 must be present to avoid fault.
All values must be equal to or larger than the value to its left. Between two set of parameters (PFC vs
position) linear interpolation is used.
Parameter setting is done with the service tool.

Warnings
PVED-CC4 warnings
Warning
Not applying to the Operational Conditions can compromise safety.
A PVG with PVED-CC4 can only perform according to the present descriptions if conditions in this
Technical Information are met.
In particularly environmental exposed applications with PVE, protection in the form of a shield is
recommended.
When the PVED-CC4 is in modes related to fault the validity of module reporting is limited by the fault
type.
Deviation from recommended torque when mounting parts can harm performance and module.
All brands and all types of directional control valves – including proportional valves – can fail and cause
serious damage. It is therefore important to analyze all aspects of the application. Because the
proportional valves are used in many different operation conditions and applications, the machine
builder/ system integrator alone is responsible for making the final selection of the products – and
assuring that all performance, safety and warning requirements of the application are met.
When replacing the PVE, the electrical and the hydraulic systems must be turned off and the oil pressure
released.
Protect persons and environment against oil spill. Hydraulic oil can cause both environmental damage
and personal injuries.
Module replacement can introduce contamination and errors to the system. It is important to keep the
work area clean and components should be handled with care.
The PVED-CC4 is not designed for use with voltage outside nominal for more than 5 minutes per hour
and maximum 10% of operating time.
When the PVED-CC4 recognizes a fault it can enter fault mode and disable the operators control of the
valve.
Obstacles for the Pilot oil can have direct influence on spool control.
Reduced pilot pressure will limit spool control.
Too high pilot pressure can harm the system.
When performing service. especially at temperatures below 0°C [32°F], avoid twisting and rough
handling.

Closed loop
PVED-CC spool positioning
Flow control
When PVED is unpowered or in power save mode the main spool is kept in blocked/ neutral position by
the neutral spring. By use of the handle (PVM) or the solenoid valves and the Pp the spool can be moved
to any position and so open for system pressure to the application.
Micro-controller: Solenoid control is run at 40Hz in operation mode Full Operational
Solenoid valve control is deactivated in power save. Monitoring is still active.
Extend is defined as spool moving away from PVE and equals positive values.
•
Retract is defined as spool moving towards PVE and equals negative values.
•
In Full Operational mode the PVED-CC4 responds to Auxiliary valve command - AVC. To control the PVEDCC4, send AVC messages to it. (ISO11783-7 section B.13)

PVED-CC settings
A number of OEM settings has influence on the fault monitoring.
General timeout (GTO)
The GTO is the time limit a filtered fault must be present before it is recognized as a fault.
Float timeout (FTO)
As the GTO but only for entering and leaving float.
Auxiliary valve timeout (AVCTO)
The AVCTO works as a watchdog on the controller AVC. The setting can be from 0 to 65535 ms in step of
10 ms. Setting 0 ms disables timeguarding, meaning last received set point is always valid. AVCTO
