Name Meaning
Memory Error flag This error occurs when the contents of the memory have been destroyed, the CPU
goes out of control, or when power is turned off before the response is received to the
EEPROM Write command. Turn the E5ZD off and then on again. If recovery is not
possible by initializing both RAM (with the Initialize Parameters command), and then
EEPROM (with the EEPROM Write command), E5ZD calibrations may have been
destroyed.
Sensor AD Error flag The sensor AD converter circuitry may have failed. Turn the E5ZD off and on.
Current Transformer AD Error
flag The Current Transformer AD converter circuitry may have failed. Turn E5ZD power off
and on.
Cold Junction Compensation
Error flag This error is generated when CN3 has been disconnected or the ambient temperature
of the E5ZD has dropped below –15
°
C or exceeded 60
°
C. For the E5ZD-8
jj
KJ-E it
is generated when CN903 is not connected correctly, and for the E5ZD-8H
j
KJM-E it
is generated when the two terminal blocks for thermocouple input are disconnected.
Parameter Error flag This error is generated when parameters in memory have been destroyed or parame-
ters that do not agree with switch settings have been written into memory. Reinitialize
memory with the Initialize Parameters command. The error may also be generated if
°
C is changed to
°
F or vice versa.
Response Examples This response shows a memory error for Unit 0.

End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been read. Re-
