10 Operation

After power on, the unit is in the Run mode (= normal operating mode)� It carries

out its measurement and evaluation functions and provides output signals

according to the set parameters�

Operation indication → chapter 7 Operating and display elements.

10.1 Read set parameters

►

Press [Mode/Enter] until the requested parameter is displayed�

►

Press [Set] briefly�

> The unit displays the corresponding parameter value for approx� 15 s� After

another 15 s it returns to the Run mode�

10.2 Error indications

[OL]

Overload pressure (above measuring range)�

[UL]

Underload pressure (below measuring range)�

[SC1]

Short circuit in OUT1*�

[SC2]

Short circuit in OUT2*�

[SC]

Short circuit in both outputs*�

[Err]

Flashing: internal fault

*The output concerned is switched off as long as the short circuit exists�

The messages SC1, SC2, SC, Err are shown even if the display is switched off�
