WARNING
Electric shock
Failure to install covers and ground leads could result in serious injury or death.
Install all protective equipment covers and safety ground leads after
troubleshooting.
9.1
Overview
This troubleshooting section describes how to identify and isolate faults that may
develop in the transmitter. When troubleshooting the transmitter, reference the
following information.
9.1.1
Grounding
It is essential that adequate grounding precautions are taken when installing the
system.
Thoroughly check both the probe and electronics to ensure the grounding quality
has not degraded during fault finding. The system provides facilities for 100
percent effective grounding and total elimination of ground loops.
9.1.2
Electrical noise
Emerson has designed the analyzer to operate in the type of environment
normally found in a boiler room or control room.
Noise suppression circuits are employed on all field terminations and main inputs.
When fault finding, evaluate the electrical noise being generated in the immediate
circuitry of a faulty system. Ensure all cable shields are connected to earth.
9.1.3
Electrostatic discharge
CAUTION
Electrostatic discharge can damage ICs in the electronics.
Before removing or handling the processor board or the ICs, ensure you are at
ground potential.
