Proline Promag 300 Modbus RS485 Description of device parameters
Endress+Hauser 131
Additional information Selection
• Actual value
In the event of a device alarm, the frequency output continues on the basis of the current
flow measurement. The device alarm is ignored.
• Defined value
In the event of a device alarm, the frequency output continues on the basis of a
predefined value. The Failure freq. (→ 131) replaces the current measured value,
making it possible to bypass the device alarm. The actual measurement is switched off
for the duration of the device alarm.
• 0 Hz
In the event of a device alarm, the frequency output is "switched off".
NOTICE! A device alarm is a measuring device error that must be taken seriously. It can
affect the measurement quality such that the quality can no longer be guaranteed. The
Actual value option is only recommended if it can be guaranteed that all possible alarm
conditions will not affect the measurement quality.
