6.4 Disassembly procedures
Do not remove the instrument cover in explosive atmospheres when the circuit is live.
6.4.1 Removing from service
1. Follow all plant safety rules and procedures.
2. Power down device.
3. Isolate and vent the process from the transmitter before removing the transmitter from
service.
4. Remove all electrical leads and disconnect conduit.
5. Remove the transmitter from the process connection.
a. The Rosemount 2088 Transmitter is attached to the process by a single hex nut
process connection. Loosen the hex nut to separate the transmitter from
the process.
b. The Rosemount 2090F Transmitter is attached to the process with a Tri Clamp or
similar attachment. Remove the Tri Clamp or attachment to separate the
transmitter from the process.
Analog
Output
Fixed
ANLOG
FIXED
ANALOG
FIXED
The analog output is fixed
and does not represent
the process
measurement. This may
be caused by other
conditions in the device,
or because the device has
been set to loop test or
multidrop mode.
1. Take action on any other notifications
from the device.
2. If the device is in loop test, and should no
longer be, disable or momentarily remove
power.
3. If the device is in multidrop mode and
should not be, re-enable loop current by
setting the polling address to 0.
Simulation
Active
[none] [none]
The device is in simulation
mode and may not be
reporting actual
information.
1. Verify that simulation is no longer
required.
2. Disable simulation mode in service tools.
3. Perform a Device Reset.
Analog
Output
Saturated
ANLOG
SAT
ANALOG
SAT
The analog output is
saturated either high or
low due to the pressure
either above or below the
range values.
1. Check the pressure applied to ensure it is
between the 4–20mA points.
2. Check the transmitter pressure
connection to make sure it is not plugged
or isolating diaphragms are not damaged.
3. Replace the pressure transmitter.
