8.11 Using the password function

You can protect the pressure sensor from unauthorized access by entering a
password. If a password has been assigned, settings can only be changed if the
password is entered.
Password "2677" is reserved for resetting the password.
If the first chosen password is "2677", the password is not reset.

8.11.1 Assigning a new password or changing a password

The pressure sensor is in the extended programming functions (EF).
1. Select menu item PAS and press the center button.
The last selected password appears in the display.
2. Use one of the two arrow buttons to select a password consisting of a 4-digit
code.
3. Press the center button to accept the selected setting.
By setting "0000" you turn off the password function.

8.11.2 Resetting the password

If the password is reset, the pressure sensor continues to use the set
parameters.
Enter the password "2677".
u
The password is reset.
Or
1. Make sure the system part in which the pressure sensor is installed is not un-
der pressure or voltage.
2. Disconnect the pressure sensor from the supply voltage.
3. Hold down both arrow buttons and the center button while you reconnect the
pressure sensor to the supply voltage.
The password function is switched off and all previous settings are returned to
the factory settings.

8.12 Resetting previously set parameters

The pressure sensor is in the extended programming functions (EF).
1. Select menu item RES and press the center button.
2. Select the setting YES with one of the two arrow buttons.
3. Press the center button to confirm the selection.
All parameters now reflect the factory settings.

8.13.1 Changing parameter values

Setting LTP1 (changing values)
1. Press the arrow pointing downwards for more than 2 s. This takes you to the
LTP1 setting.
2. Press the center button to change this setting.
3. Use the two arrow buttons to change the values and the press the center ar-
row button again to accept the desired value.
Setting LTP2 (duration of measurement)
1. Press the arrow pointing downwards for more than 2 s. This takes you to the
LTP2 setting.

2. Repeat the steps as described under setting LTP1.
3. Press the arrow pointing downwards and then press the center button to con-
firm.
4. Use both arrow buttons to set the TOUT measurement duration (in seconds,
from 1 to 9999) and then press the center button to confirm.
Setting the system/system section volume (if known)
1. Press the arrow pointing downwards to go to the menu for setting the volume
and then press the center button to confirm.
2. Set the values with the two arrow buttons.
At the end of the measurement, the display shows the leak rate information in L/
min.
SET AMODE
1. Press the arrow pointing downwards to go to the SET AMODE menu and then
press the center button to confirm.
2. Use the two arrow buttons to select the value to be transmitted via the analog
output, either the measurement duration (dT) or the pressure difference (dP).
STOP LT
1. Press the arrow pointing downwards to go to the STOP LT menu and then
press the center button to confirm.
2. Use the two arrow buttons to select if you want to use the sensor in leakage
mode (select NO) or as a pressure sensor (select YES), and then press the cen-
ter button to confirm.
3. Press the arrow pointing downwards.
The sensor is set to measurement readiness in the corresponding mode.

8.13.2 Starting the leakage measurement

After connecting the sensor to the power supply, it displays the corresponding
firmware version "FWv x.xx". The display shows the initialization "PE5 Aventics",
the current system pressure p0 as well as "Wait" and "User" in the lower two
lines.
Press the center button for > 200 ms to start the measurement with the pre-
u
set parameters.
The factory setting is:
p1 = 0.6 bar
p2 = 0.4 bar
tout = 30 seconds
PVOL = 0.0 liters
QA = dT
Alternatively, the measurement can be started with a pulse from a control (PLC).
The pulse is sent to the sensor as an input signal via Q1 (pin 4).
The upper part of the display always shows the current measured value.
The following scenarios can occur during the measurement:
System supply pressure p0 < (pressure) threshold value p1 or p2
After starting the measurement, the sensor immediately enters an error mode if
the value for p0 is not at least 0.02 bar higher than the upper threshold value p1.
The display changes to red. "WARN" is shown below the current measured value,
and "p<p1" as well as the value for p1 (e.g. "0.60"), or "p<p2" and the value for
p2 appear in the bottom line.
Press the center button to acknowledge the message and return the sensor to
u
measurement readiness.
Supply pressure p0 > p1 and reaching tout before value falls below p1
Timer A starts after the start of the measurement. The upper threshold value p1
is not reached by the time tout is reached. During the measurement, "TimA" ap-
pears in the upper status bar with the corresponding time in seconds, and in the
lower status bar "P>P1" appears with the value for p1 (e.g. "0.60"). The measure-
ment stops as soon as the time value for tout is reached. "DONE" appears in the
upper status bar to indicate that the measurement has been completed. In the
lower status bar, the display alternates between the values for dP (pressure differ-
ence between p0 and the current pressure when tout is reached), dT (corre-
sponds to tout in this case), and the value for QL (absolute value if a volume has
been specified, or "- - - -QL" if the setting Vol = 0 has been retained).
Press the center button to acknowledge the message and return the sensor to
u
measurement readiness.
Supply pressure p0 > p1 and value below p1 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 p0 and the current pressure), dT (time period in seconds since
