Mounting Instructions

During operation of the Sensors, the corresponding electrical and mechanical regulations, as well as safety regulations must be observed. Suggested tightening torque of process connection 15 Nm.

Note! Before disassembly, it must be ensured that the system is depressurized, otherwise there is a risk of injury. The pressure membrane of front flush sensors must not be touched. Do not remove the protective cap until ready to install.

Initial Start-Up

After switching on the device, 888 flashes on the display for 3 s (initialization phase). Then the device is ready for operation and the applied pressure is shown on the display. The parameters such as NC / NO, switching point etc. can be changed via a simple menu by pressing the three buttons (see operating structure).

Note! When using sharp objects, the membrane covering the buttons may be damaged.

Display Messages

Display	Comment
888	Sensor is initializing
Pmax	Pressure above measuring range
Er0	Not possible to correct offset, pressure exceeding 2% of measuring range
Er3	Internal sensor fault

Settings

To view or change the parameters press the button 2× within 10 s, then press the  button 2× and finally the button 2×. From the main level, the and  buttons can be used to select other main levels, menu items and sub-menu items (see operating structure). At the end of a menu branch, the  button can be used to modify or switch the parameters. To confirm the parameters or to exit a menu item press the button. The parameters are not activated until the menu is closed. If the supply voltage is interrupted, the modified parameters will not be saved.
