MIN:XQ / MAX:XQ (LVDT setting):
MIN:XQ Displacement sensor feedback at dead head (LVDT-0%) in mV.
MAX:XQ Displacement sensor feedback at full stroke (LVDT-100%) in mV.
Both parameters are shown at the pump enclosed tag.
Pumps are tested at a fluid temperature of (50±2)°C. Small deviation of the LVDT parameters

6.2 MODE – EXPERT (EXP)
TRIGGER (Response Delay):
The response delay describes a kind of dead band (in 0,01% of full scale) to compensate for unwanted
command signal changes (e.g. ripple in the command signal) and command signal noise in p and Q.
TRIGGER influences the command signals transfer and processing. The pumps small signal
quality is indirect proportional to the TRIGGER parameter.
A value of 1000 indicates a pump reaction with command signal of 1V. The rest of the command
value 1-10V is equal distributed to 100% WP or WQ respectively (e.g. 50% actual value is reached
with 5,5V).
SOLENOID (Number of solenoids of the Displacement control valve):
Selection of the number of solenoids at the Displacement control valve.
With the change of parameter SOLENOID, CQ:MINVA CQ:MINVB, CQ:MAXVA, CQ:MAXVB and
CQ:FFneedtobeadjustedaswell.
