Error occurs whenever the control reverts to failsafe operation and remains
as long as the condition exists.
Indicates that an error exists in the working calibration data. Re-select the
inputs to load factory calibration data or field calibrate the inputs.
Error exists in the configuration data. Verify configuration data at the
keyboard. Checksum will be recomputed by stepping the controller through
the status tests.
Error exists in the factory calibration data and remains as long as the
condition exists.
Indicates either a RAM tests failure or Input 1, Input 2, Input 3 failure on two
consecutive conversions.
Error occurs whenever a shed of slave override is performed. Error is reset
following a WRITE command to I.D. code 255 (064).
