Minimum: Maximum:
50.0 400.0
The pressure at which the pressure sensor at the A and B cylinder ends outputs
10 V is entered in bar in MD 5550: PRESSURE_SENS_A_REF and MD 5552:
PRESSURE_SENS_B_REF.
The pressure sensor should have a range of 0 to 10 V, with 0 bar pressure rep-
resented by 0 V and the reference value (MD 5550 or. MD 5552) by 10 V.
Minimum: Maximum:
-32760 32760
Minimum: Maximum:
-32760 32760
The offset of the pressure sensor at the cylinder A and B ends is adjusted in
ADC increments in MD 5551: PRESSURE_SENS_A_OFFS and MD 5553:
PRESSURE_SENS_B_OFFS.
The pressure indicator should also display 0 bar at zero pressure. If the
velocity controller cycle is altered, the offset must be adjusted again.
Note
For automatic offset adjustment, see Section 3.9.2.
