MONITORING MODE
9100 Use this function to suppress / output the following
error messages:
• #701 EXC. CURR. LIM.
• #701 FLUID INHOM.
• #701 NOISE LIM. CH0
• #701 NOISE LIM. CH0
• #701 FLOW LIMIT
Options:
OFF = Error messages
are suppressed.
ON = Error messages
are output.
OSCILLATION AMPLITUDE
9101 Use this function to increase or decrease the oscillating
amplitude of the measuring tubes relative to the
standard value of 100%.
User input: 50 to 150%
of standard value
GAIN AMPLIFIER
9102 Use this function to enter the relative signal
amplification
User input: 25 to 150%
of standard value
MONITOR INTERVAL
9102 Use this function to specify the time from when a fault
occurs to when it is signaled by means of an error
message on the onsite display or at the outputs.
This interval also applies to the time from when the
fault is eliminated to when the error message is
removed from the onsite display or the outputs.
User input:
1.0 to 100 s
