SECTION 8 – TROUBLESHOOTING
Personnel should be familiar with the operation of the CAMM (see Section 5) before performing any
troubleshooting.
Problem
No Display and "CPU
Activated" LED is not lit.
No output or incorrect output
(Transmitter Output) and
display responding correctly
with process change.
No output or incorrect output
(Transmitter Output) and
display not responding or
correctly with process
change.
No output or incorrect output.
(Temperature, Absolute
Pressure, or Special
Function).
Special Function not working.
AUTO-zero Function
is not working.
"AUTO-zero in Progress"
LED is continuously lit.
"AUTO-zero in Progress"
LED is flashing rapidly.
Solution
– Verify input power is present at the correct voltage as listed on label and connected to
Terminals 15 and 16.
– Verify power switch 1 is in the ON position.
– Check fuse F2 inside CAMM (see Figure 5.2 for location).
– Replace I/O Board.
– Review Factory Set-Up Information Sheet for type of output.
– Check terminal strip wiring for proper installation.
– Verify jumpers are correct for desired type of output (see Section 4.6).
– Perform Transmitter Output Calibration (see Section 6.4).
– Replace I/O Board.
– Verify pressure signal lines are connected correctly.
– Check for leaky or obstructed lines between CAMM and process sensor.
– Check for kinked internal signal pressure lines in transmitter base.
– Replace Transducer.
– Replace CPU Board.
– Verify correct input is applied for process application or special function.
– Verify jumpers are correct for desired type of output (see Section 4.6).
– Check wiring for proper installation.
– Verify menu configuration setup is correct for process application or special function.
– Replace I/O Board.
– Verify that Special Function is ON and desired type is selected (see Section 5.12).
– Verify special function parameters (depends on type selected) are configured properly (see
Section 5.12).
– Verify any required external input is connected properly (see Section 4.5).
– Verify any required external input is calibrated properly (see Section 6.3).
– Replace I/O Board.
– Verify AUTO-zero is ON and interval is properly set (see Section 5.10).
– Replace I/O Board.
– Zero value measured during AUTO-zero cycle is between 90 and 100% of span. Transmitter
Input Calibration should be performed as soon as possible (see Section 6.3).
– Replace CPU Board.
– Zero value measured during AUTO-zero cycle is greater than 100% of span. Transmitter
Input Calibration should be performed immediately (see Section 6.3).
– Replace Transducer.
If after following the Troubleshooting steps the CAMM continues to operate improperly,
contact the Service Department for further assistance (see Section 10).
