STATUS OF PUMP MECHANISM
Item
Description
PACT
Actual pressure.
PAVG
Middle pressure during one cycle.
PULS
Pressure pulsation (bandwidth PMAX – PMIN) per one cycle.
DEAD
Status of optical switch detecting position of top dead center of main (left)
piston – CLOSE/OPEN.
MAGV
Motor load mean value (% of maximum allowed load).
MMAX
Motor load peak value (% of maximum allowed load).
CAMR

PUMP PULSATION STATUS
Item
Description
PU01
Pulsation during last rotation.
PUAN
Average pulsation in n rotations, n is determined by firmware based on
actual flowrate.
PUBT
Best reached pulsation during learning process.
PULI
Pressure pulsation limit.
PAVG
Average pressure in one rotation.
LTIM
Learning time – time lapsed from learning start.
LFLO
Learning flow – flowrate during learning (constant).
PPOS
Actual piston position.
Note: After start of compensation learning (see 6.3.1) for items PUAN, PUBT displayed
---. Values of pulsation are displayed after n rotations. At this moment is learning
process started.
6.6.10. Gradient State
On main screen is displayed GRAD. In this menu item is displayed status of values for
controlling gradient valve.
