passing through p1), and QL. After tout has expired, "DONE" appears in the up-
per status bar, and the values for dP, dT, and QL appear alternately in the lower
status bar.
Press the center button to acknowledge the message and return the sensor to

measurement readiness.
Supply pressure p0 > p1 and values below p1 and p2 before reaching tout
If the upper pressure value P1 is not reached after the start of the measurement,
measurement of dT starts. "MEAS" then appears in the upper status bar. In the
lower status bar, the display alternates between the values for dP (pressure differ-
ence between p1 and p2), dT (time period in seconds since passing through p1
until reaching p2), and QL. If the value falls below the lower (pressure) threshold
P2, the display color changes from green to red.
There is a leak. Fig. 23 shows a schematic depiction of the leakage measurement.

9 Service and Maintenance

The device is maintenance-free.
Only use water and, if necessary, a mild cleaning agent for cleaning.

10 Disassembly and Exchange

System is under high pressure!
Danger of injury and system damage from uncontrolled system operating
states.
Make sure that the system component in which the pressure sensor is in-
u
stalled is not under pressure or voltage before beginning disassembly.
1. Make sure that the system is not under voltage or pressure.
2. Loosen and remove all connections.
3. Loosen the pressure sensor from the (threaded) pressure connection using a
wrench, or pull the pressure sensor straight out of the push-in fitting.
4. Dispose of the packaging and used parts in accordance with the regulations of
the country where used.

11 Error and Warning Messages

The display areas A and B blink in case of error and warning messages (Fig. 2).
Display Cause
OL OVERPRESS Applied pressure > end of
measuring range
UL UNDERPRES Applied pressure < start of
the measuring range
ERR1 GEN.ERROR General error
ERR2 SHORTOUT1 Short-circuit present at
output 1
ERR2 SHORTOUT2 Short-circuit present at
output 2
ERR3 OVERVOLTG Supply voltage > 30 V DC
ERR4 LOW VOLTG Supply voltage < 17 V DC
ATT1 SHIFT RP1 The switching point is set
below the existing reset-
ATT1 SHIFT RP2
ting point. The resetting
point is automatically set
with the smallest possible
hysteresis below the new
switching point.

CAUTION
Remedy
Set the pressure within
the measuring range (see

ment, the applied pres-
sure is outside the permis-
sible limit of 5% of the
range.
LOCK KEYLOCKED If the key lock is active,
the system will attempt
to go into the program-
ming mode.
WARN (p<p1) The value for p0 is not at
least 0.02 bar higher than
the upper threshold value
p1.
1)
The outputs switch off if the supply voltage exceeds 30 V DC or falls below
17 V DC.
If a second switch output is present, you can configure it as a diagnostic output.
In the extended programming functions (EF), select the value "DIA" for the
u
parameter "OUT2" (see "Selecting the extended programming functions").
