timeout
P3078 U16 x10mSec
Cut Off Valve Activation Timeout for COV Monitoring feature while
entering Off Road state.
INFO: Setting this parameter to 0 will bypass off-road safety check
OEM 0 1000 900 S
Invert flow direction P3080 U8 -
Changes the direction of the requested flow
Valid Values: 0 (NO, DEFAULT OSPE/EHi); 255 (YES, DEFAULT
EHPS)
OEM 0 255 0 S
Valve type P3081 U8 -
Valve type on which the PVED-CLS is mounted
Valid Values: 0 (OSPE, EHi-E); 1 (EHPS); 2 (EHi-H)
OEM 0 2 0 S
Turns lock-to-lock
EHPS
P3082 U16 -
Number of steering wheel turns lock-to-lock, without PVED-CLS activated
(hence pure hydraulic). Lock-to-lock is dependent on:
• OSP displacement
• EH-spool and pilot flow
• Standby pressure (spring force)
• Cylinder volume
Contact your local technical support at Danfoss Power Solutions for
specific calculation, or simply do the measurement/exercise on the vehicle
Resolution: 0.01 turns
OEM 100 1000 450 S
OSP displacement P3084 U16 Ccm
OSP displacement, number of cubic centimeters per revolution
Note: When the PVED-CLS is mounted on an EHPS this parameter
must be set equal to 0!
OEM 0 1200 120 S
Cylinder stroke volume P3086 U16 Ccm
Cylinder stroke volume.
Acceptable values: 100-10000.
Note: Writing values >10000 will force to use automatic adjusted
cylinder stroke volume-value on WAS calibration

Pass criteria
P3100 U8 dec
P3100 specifies how many safety check cycles with successful EH-Spool
control shall be executed before PVED-CLS passes the safety checks.
OEM 2 8 2 S
Safety checks IMD -
Maximum fall time
P3101 U16 x10mSec
If the EH-Spool does not return to neutral within this timeout, the cut-off
solenoid is concluded to be stuck open.
