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-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 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 measurement 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 difference between p0 and the current pressure when tout is reached), dT (corresponds 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).

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 difference between p0 and the current pressure), dT (time period in seconds since 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.
“DONE” appears in the upper 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.
