Description of parameter
Cut-off Valve Present/Not Present
-
Valid Values: 0 (NOT PRESENT); 255 (PRESENT)
Cut-off Valve control mode Close loop Control or ON-OFF control
-
Valid Values: 0 (ON-OFF control); 255 (Closed loop control)
mAmp Current required to activate Cut-off valve
mAmp Current required to maintain to Cut-off in ON state
Cut Off Valve Activation Timeout for COV Monitoring feature while
x10mSec entering Off Road state.
INFO: Setting this parameter to 0 will bypass off-road safety check
Changes the direction of the requested flow
- Valid Values: 0 (NO, DEFAULT OSPE/EHi); 255 (YES, DEFAULT
EHPS)
Valve type on which the PVED-CLS is mounted
-
Valid Values: 0 (OSPE, EHi-E); 1 (EHPS); 2 (EHi-H)
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
OSP displacement, number of cubic centimeters per revolution
Ccm Note: When the PVED-CLS is mounted on an EHPS this parameter
must be set equal to 0!
Cylinder stroke volume.
Acceptable values: 100-10000.
Ccm
Note: Writing values >10000 will force to use automatic adjusted
cylinder stroke volume-value on WAS calibration
Lpm EH valve size, defined in liters per minute
LVDT Offset compensation Enable/Disable
-
Valid Values: 0 (DISABLE); 255 (ENABLE)
10 um
Absolute value of Spool neutral threshold range
(signed Dec)
Spool left most position copied by spool auto-calibration before the internal
x10um
calculation of the sector CRC
x10um Spool right most position copied by spool auto-calibration before the
internal calculation of the sector CRC
x10um Spool open loop dead-band offset copied by spool auto-calibration before
the internal calculation of the sector CRC
% Cut-off valve PWM pre-load value
Maximum rise time after switching ON cut-off valve for indicating EH-
x10mSec
Spool is under control during safety check.
Maximum fall time after switching OFF cut-off valve for indicating EH-
x10mSec
Spool is under control during safety check
P3100 specifies how many safety check cycles with successful EH-Spool
dec
control shall be executed before PVED-CLS passes the safety checks.
If the EH-Spool does not return to neutral within this timeout, the cut-off
x10mSec
solenoid is concluded to be stuck open.
