FAILSAFE MODE
!
Note!
This function is not available unless the PULSE option was selected in the OPERATING
MODE function.
The dictates of safety render it advisable to ensure that the pulse output assumes a
predefined state in the event of a fault. Use this function to define this state. The setting
you select here affects only the pulse output. It has no effect on other outputs or the
display (e.g. totalizers).
Options:
FALLBACK VALUE
Output is 0 pulse.
HOLD VALUE
Measured value output is based on the last measured value saved before the error
occurred.
ACTUAL VALUE
Measured value output is based on the current flow measurement. The fault is ignored.
Factory setting:
FALLBACK VALUE
ACTUAL PULSE
!
Note!
This function is not available unless the PULSE option was selected in the OPERATING
MODE function.
The current computed actual value of the output frequency appears on the display.
Display:
0...100 pulse/second
SIMULATION PULSE
!
Note!
This function is not available unless the PULSE option was selected in the OPERATING
MODE function.
Use this function to activate simulation of the pulse output.
Options:
OFF
COUNTDOWN
The pulses specified in the VALUE SIMULATION PULSE function are output.
CONTINUOUSLY
Pulses are continuously output with the pulse width specified in the PULSE WIDTH
function. Simulation is started once the CONTINUOUSLY option is confirmed with the
F
key.
!
Note!
Simulation is started by confirming the CONTINUOUSLY option with the
F
key. If the
F
key is pressed again afterwards, the prompt “End simulation” (NO/YES) appears.
If you choose “NO”, simulation remains active and the group selection is called up. The
simulation can be switched off again via the SIMULATION PULSE function.
If you choose “YES”, you end the simulation and the group selection is called up.
