Screw the filter cover again tightly.
The sensor is sufficiently protected against harsh ambient conditions (protection
IP 67). The protection rating can be increased by a special accessory (order no.
E30043).
8 Parameter setting
Parameters can be set before installation and set-up of the unit or during opera-
tion.
If you change parameters during operation, the operating principle of the
plant will be influenced.
►
Ensure that there will be no malfunctions in your plant.

Parameter setting with PP2001 →operating instructions enclosed to PP2001.
8.1 Adjustable parameters
ASP
Analogue start point
Measured value at which 4 mA is provided.
AEP
Analogue end point
Measured value at which 20 mA is provided.
Minimum distance between ASP and AEP = 25% of the span.
HI
LO
Min-Max memory for system pressure
• HI: displays the highest measured pressure.
• LO: displays the lowest measured pressure.
COF
Calibration offset
The internal measured value (operating value of the sensor) is offset against the
real measured value.
• Setting range: -5 ... +5% of the value of the span (with scaling as factory setting
(ASP = 0 bar and AEP = final value of measuring range) in steps of 0.1% of the
value of the span.
CAr
Calibration reset
Resets the calibration set by COF.
dAA
Damping for the analogue output
Pressure peaks of short duration or high frequency can be filtered out.
dAA-value = response time between pressure change and change of the switch-
ing status in milliseconds (ms).
•
Setting range: 0 (= dAA is not active) / 0.1 s / 0.5 s / 2 s.
Uni
Display unit
The measured values and values for ASP / AEP can be indicated in the following
units:
bar, mbar, PSI, MPa, kPa, inH2O (only PL2058), mmWS (only PL2058).
