Emerson Micro Motion 2500, Configuration And Use Manual

If communication with the transmitter cannot be established, the transmitter may
need service. Contact customer service.
12.17 Check HART Address and mA Output Action
If the transmitter is producing a fixed current from the mA Output, the mA Output Action
parameter may be set incorrectly.
When the mA Output Action parameter is set to
Fixed
, the mA Output produces a fixed
value, and does not report process data or implement its fault action.
When HART Address is changed, some configuration tools will automatically change mA
Output Action.
Tip
Always verify mA Output Action after setting or changing HART Address.
Procedure
1. Set HART Address as appropriate for your HART network.
The default address is 0. This is the recommended value unless the transmitter is in a
multidrop network.
2. Set mA Output Action to Live .
12.18 Check HART burst mode
HART burst mode is normally disabled, and should be enabled only if a HART Triloop is
being used.
1.
Check to see if burst mode is enabled or disabled.
2. If burst mode is enabled, disable it.
12.19 Check Lower Range Value and Upper Range
Value
If the process variable assigned to the mA Output falls below the configured Lower Range
Value (LRV) or rises above the configured Upper Range Value (URV), the meter will post a
saturation alert (A100), then perform the configured fault action.
1.
Record your current process conditions.
2. Check the configuration of the LRV and URV.
