Device Functions Proline t-mass 65 11 Group PULSE/FREQUENCY OUTPUT
Endress+Hauser 39
FAILSAFE MODE For safety reasons it is advisable to ensure that the pulse output assumes a predefined
state in the event of a fault. The setting you select here affects only the pulse output. It
has no effect on other outputs and the display (e.g. totalizer).
! Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function.
Options:
FALLBACK VALUE
Output is 0 pulse.
ACTUAL VALUE
Measured value output is based on the current flow measurement. The fault is ignored.
Factory setting:
FALLBACK VALUE
SIMULATION PULSE Use this function to activate simulation of the pulse output.
! Note!
This function is not available unless the PULSE option was selected in the OPERATING
MODE function.
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 flowmeter 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.
