8 Commissioning and Operation
Dangerous system operating states from incorrect settings or if the maxi-
mum/minimum operating voltage is exceeded!
Danger of injury and system damage from uncontrolled system operating
states.
1. Do not make any improper changes to the pressure sensor during opera-
tion. Note that the previous settings become immediately effective if the
center button is pressed!
2. Immediately exchange defective pressure sensors.
3. Do not disconnect the pressure sensor from the voltage source during op-
eration!
Danger caused by the repeated compression of the pressurized air!
The device heats up beyond the permissible limit.
1. Avoid repeated compression of the pressurized air.
2. For the permissible period T as a function of the pressure fluctuation Δp,
see Fig. 18.
Damage due to sharp objects!
The device may be damaged.
Never operate the device with tools or sharp objects.
u
Before commissioning the system, the following steps must have been carried
out and completed:
• You have fully assembled and connected the pressure sensor.
• You have carried out the presettings and configuration.
You can now pressurize the system part to which the pressure sensor is con-
nected.
8.1 Switching on the device
After connecting to the power supply, all segments of the display are illuminated
for 2 s in the basic color and then for 2 s in the warning color.
Check the error-free function of all segments during this time.
u
The device will then display the manufacturer name and device designation for
2 s. Afterwards, the device changes to the display mode.
The measuring and switching functions are operational in the display mode.
In the case of an electrical start-up, the device may already show a
value in a pressure-free state (physical effect). During commissioning,
perform a zero point offset in the EF extended program function with
the function "0SET".
The device switches off the display in the energy saving mode. Pushing one of the
buttons reactivates the display for 5 s.
To switch on the energy saving mode:
In the extended programming functions, select the value "OFF" for the pa-
u
rameter "DISC" g 8.8. Selecting the extended programming functions.
8.2 Selecting the information mode
The pressure sensor is in display mode:
Press and hold the arrow pointing upwards for at least 3 s.
u
The pressure sensor is now in the information mode.
The device displays the following parameters in sequence for 3 s each:
• SP1/FH1 (setting for switching point 1 or upper window limit 1)
• RP1/FL1 (setting for resetting point 1 or lower window limit 1)
• SP2/FH2 (setting for switching point 2 or upper window limit 2)
• RP2/FL2 (setting for resetting point 2 or lower window limit 2)
• Analog output (electrical output signal in mA or V)
• LOW (minimum applied pressure value stored since the last reset)
• HIGH (maximum applied pressure value stored since the last reset)
To exit the information mode:
Press both arrow buttons at the same time.
u
The pressure sensor is now in the display mode.

8.3 Display areas
The display areas differ between the pressure sensor and the pressure sensor with
additional leak tester function (Fig. 2).

8.4 Selecting the programming mode
The pressure sensor is in display mode:
Press the arrow pointing downwards for at least 2 s.
u
The pressure sensor is now in the programming mode. The measuring and
switching functions continue.
If you do not make an entry for more than 15 s, the device automatically switches
back to the display mode.
8.5 Selecting menu items or parameters
The pressure sensor is in the programming mode:
The device displays menu items and selectable parameters in the display area B
(Fig. 2).
Use the two arrow buttons to select the menu item or parameter to be set.
u
To confirm the menu item or parameter:
Press the center button.
u
The menu item will be implemented or you can set the parameter values.
8.6 Setting parameter values
The pressure sensor is in the programming mode:
The device displays parameter values in the display area A (Fig. 2).
The display areas C1/2 and D1/2 show the currently set parameter values.
1. Use the two arrow buttons to select the parameter value to be set.
2. Press the center button to confirm the parameter value.
The setting becomes active, although the device is still in the programming
mode.
