Proline Prowirl 73 Description of device functions
Endress+Hauser 127
SIMULATION
FREQUENCY
Prerequisite
The function is only available if FREQUENCY was selected in the OPERATION MODE
function (ä 122).
Description
Use this function to activate simulation of the frequency output.
• The notice message "SIMULATION FREQUENCY OUTPUT" (ä 67) indicates that
simulation is active.
• The measuring device continues to measure while simulation is in progress i.e. the
current measured values are output correctly via the other outputs.
!
Note!
The setting is not saved if the power supply fails.
Options
OFF
ON
Factory setting
OFF
VALUE SIMULATION
FREQUENCY
Prerequisite
The function is only available if FREQUENCY was selected in the OPERATION MODE
function (ä 122) and ON was selected in the SIMULATION FREQUENCY function
(ä 127).
Description
Use this function to specify an arbitrary frequency value (e.g. 500 Hz) to be output at the
frequency output. This value is used to test downstream devices and the measuring
device itself.
!
Note!
The setting is not saved if the power supply fails.
Procedure
• Simulation is started once the specified value is confirmed 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 diagnosis code "C 482– 2 Simulation
Outp".
• If you choose "YES", you end the simulation and the group selection is called up.
User input
0 to 1250 Hz
Factory setting
0 Hz
ASSIGN PULSE Prerequisite
The function is only available if PULSE was selected in the OPERATION MODE function
(ä 122).
Description
Use this function to assign a measured variable to the pulse output.
Options
VOLUME FLOW
MASS FLOW
CORRECTED VOLUME FLOW
HEAT FLOW
Factory setting
See the parameter printout provided. The parameter printout is an integral part of these
Operating Instructions.
