Display

With this parameter you can change the display language.

This parameter is described in the operating instructions manual

"Display and adjustment module".

With this parameter you can change the indication of the display.

You can choose if the display should show the actual pulse rate or the

electronics temperature.

Diagnostics

In this menu item, you can enquire the status of your sensor. In normal

operation, the sensor displays the message "OK". In case of fault, you

willndthecorrespondingfaultcodehere.

This parameter is described in the operating instructions manual

"Display and adjustment module".

The peak value function holds the max. and min. values during opera-

tion.

This parameter is described in the operating instructions manual

"Display and adjustment module".

Here, you can retrieve the adjustment value of the sensor. This is the

percentage value of the max. pulse rate at which the sensor switches

over.

If you have carried out a single point adjustment, this is the entered

value. With a two-point adjustment, this is the calculated value.

The value is an indication for the reliability and reproducibility of the

switching point.

more reliable the measurement. The automatically calculated damp-

ing is also oriented around the Delta I value. The higher the value, the

lower the damping.

A Delta I value below 10 % is an indication for a critical measurement.

In this menu item you can simulate measured values via the current

output. This allows the signal path to be tested, e.g. through down-

stream indicating instruments or the input card of the control system.
