132 Micro Motion Series 1000 and Series 2000 Transmitters
Troubleshooting
mA output < 4 mA Process condition below LRV Verify process.
Change the LRV.
Fault condition if fault indicator is set to
internal zero
Check the fault indicator settings to verify
whether or not the transmitter is in a fault
condition.
If a fault condition is present, see Section 12.7.
Open in wiring Verify all connections.
Bad mA receiving device Check the mA receiving device or try another
mA receiving device. See Section 12.16.
Channel not configured for mA
operation (CIO transmitters only)
Verify channel configuration.
Bad output circuit Measure DC voltage across output to verify that
output is active.
Output not powered (IS transmitters
only)
Check transmitter wiring. See the installation
manual for your transmitter.
No frequency output Process condition below cutoff Verify process.
Change the cutoff. See Section 8.7.
Fault condition if fault indicator is set to
downscale or internal zero
Check the fault indicator settings to verify
whether or not the transmitter is in a fault
condition.
If a fault condition is present, see Section 12.7.
Slug flow See Section 12.17.
Flow in reverse direction from
configured flow direction parameter
Verify process.
Check flow direction parameter. See
Section 8.10.
Verify sensor orientation. Ensure that flow
direction arrow on sensor case matches process
flow.
Bad frequency receiving device Check the frequency receiving device or try
another frequency receiving device. See
Section 12.16.
Incorrect terminal configuration FO can be configured on different terminals.
Verify configuration.
Output level not compatible with
receiving device
See your transmitter installation manual. Verify
that the output level and the required receiving
input level are compatible.
Bad output circuit Perform loop test. See Section 5.3.
Incorrect internal/external power
configuration
Internal means that the transmitter will supply
power. External means that an external pull-up
resistor and source are required. Refer to your
transmitter installation manual for wiring. Verify
configuration is correct for desired application
(see Chapter 6).
Incorrect pulse width configuration Verify pulse width setting.
Output not powered (IS transmitters
only)
Check transmitter wiring. See the installation
manual for your transmitter.
