PVEA-CI and PVEO-CI Series 6 Electro-hydraulic Actuators
PVEA-CI and PVEO-CI Introduction
The PVEA-CI and PVEO-CI Series 6 are digitally controlled actuators for the PVG 16 family based on the hydraulic concept known from the analog versions of PVEA and PVEO Series 6.
PVEA-CI and PVEO-CI Series 6
Communication protocols available for PVE-CI:
•ISO 11783 part 7
•J1939-21, -71, -73, -81
CANopen according to:
•CiA 301 version 4.2.0
•CiA 305 version 1.5.2
•CiA 408 version 3.0.0

PVE-CI Communication
The Controller Area Network or simply the CAN bus is an intelligent and efficient bus communication where highly important messages have priority without any delaying message collisions.
The PVE-CI is available with ISOBUS/SAE J1939 baud rate fixed to 250 Kbps or CANopen default baud rate = 250 Kbps.
The following states are valid in both communication protocols:
Blocked |
• The spool and the two normally closed solenoid valves inside the actuator (PVE) are |
|
in neutral position. |
|
• The actuator (PVE) will enter power save mode after 200 ms in blocked state. |
|
• Power Save mode de-energizes the solenoids, while being in blocked state. As soon |
|
as a non-neutral set-point is received by the actuator (PVE) or the spool is moved |
|
the Power Save mode is aborted. |
|
|
|
The blocked position is considered to be the safe state for the PVE and valve. |
|
|
Extend |
• The extend direction is defined as the spool moving away from the PVE and |
|
entering the B-port side. |
|
• The feedback signal equals positive values. |
Retract |
• The retract direction is defined as the spool moving towards the actuator and |
|
entering the A-port side. |
|
• The feedback signal equals negative values. |
Float |
• The float state is defined as the spool being actuated fully in the side of the B-port. |
|
• When float position is achieved both A- and B-ports are connected to tank in order |
|
to allow oil flow back and forwards between tank and the work port connections. |
Hand |
• Hand operation mode will de-activate the solenoid valves inside the PVE. |
operation |
• The feedback signal will be transmitted when the spool is moved manually e.g. by a |
|
lever. |
|
• Any failures related to the spool position are ignored and will not be transmitted |
|
nor logged by internal diagnostics. The introduction of any other failures will result |
|
in a normal reaction and recovery pattern where a DM1 message is transmitted, etc. |

CAN bus If there is a bus-off situation the LED will turn red and a DM1 message will be generated. Error However the message cannot be send due to the bus-off and the application controller will
not receive a DM1 message in the event of this error. The PVEA-CI will contribute on the bus again when the bus-off situation is gone.
Diagnostic Message 1 (DM1)
The active troubleshooting code Diagnostic Message 1 (DM1) is used by the PVE-CI to transmit an active fault onto the CAN bus. The PVE-CI will broadcast one fault at a time on the CAN bus. The highest error priority will be the one broadcasted.

PVE-CI Address claim
Before a device can participate in sending CAN messages on a network, claim its address. The PVE-CI transmits its device address together with the device name to the network at boot-up.

Response: On sending the address claim request the PVE-CI sends address claim message.
Both specific and global requests for address claim are supported.
Commanded address (ISOBUS/J1939)
Commanded address is used to Change the Node ID of the valve by using the “Name field” broadcasted in the address claim message. This commanded address request is sent via a BAM once the commanded address is matched and the Node ID is valid. This will make the valve reset and announce itself with the new Node ID.
Only a sub-set of J1939-81 is supported.
The three supported capabilities according to J1939-81, Appendix B are:
•Support Commanded Address
•Address Configuration Capability
•Name Retained Across Power-up Cycles
