10 Operation
Correct operation and compliance with the measurement accuracy can only
be ensured if the environmental conditions specified in the “Technical data” (→
chapter 12) are adhered to� Ensure that the maximum pressure range, measuring
range and permitted operating temperature are not exceeded�
After power on and expiry of the power-on delay time (approx� 0�5 s) the unit is in
the Run mode (= normal operating mode)� It carries out its measurement and eval-
uation functions and generates output signals according to the set parameters�
• Operation indication → chapter 7 Controls and indicating elements.
• During the power-on delay time the outputs are switched as programmed: ON
for NO function (Hno / Fno) and OFF for NC function (Hnc / Fnc)�
• If output 2 is configured as analogue output, the output signal is at the maxi-
mum value during the power-on delay time�
10.1 Read the set parameters
► Press [Mode/Enter] until the requested parameter is displayed�
► Press [Set] briefly�
> The unit displays the corresponding parameter value for about 15 s� AAfter
another 15 s the parameter is displayed again, then the unit returns to the Run
mode�
10.2 Changing the display unit in the Run mode
► Press [Set] briefly in the Run mode� Press the pushbutton to move to the next
display unit�
> The unit displays the current measured value for approx� 15 s, the correspond-
ing LED lights�
10.3 Error indication
[SC1]
Short circuit in OUT1�*
[SC2]
Short circuit in OUT2�*
[SC]
Short circuit in both outputs�*
[OL]
Measured value > 120% of the final value of the measuring range�
[UL]
Measured value < lowest value of the measuring range�
[Err]
Fault in the measuring probe�
*The output concerned is switched off as long as the short circuit continues�
These faults are indicated even if the display is deactivated�
