Device Functions Proline Promass 80 10 Group PULSE/FREQUENCY OUTPUT
Endress+Hauser 39
FAILSAFE MODE
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
For reasons of safety it is 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 and the display (e.g.
totalizer).
Options:
FALLBACK VALUE
Output is 0 pulse.
HOLD VALUE
Measured value output is based on the last measured value saved before the fault
occurred.
ACTUAL VALUE
Measured value output is based on the current flow measurement. The fault is ignored.
Factory setting:
FALLBACK VALUE
SIMULATION PULSE
! Note!
This function is not available unless the PULSE setting 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. The
simulation can be switched off again via the SIMULATION PULSE function.
Factory setting:
OFF
! Note!
• The notice message #631 “SIM. PULSE” indicates that simulation is active.
• The on/off ratio is 1:1 for both types of simulation.
• The measuring device continues to measure while simulation is in progress, i.e. the
current measured values are output correctly via the other outputs.
" Caution!
The setting is not saved if the power supply fails.
