Note 1. A setting error will be indicated by outputting EE01 to the input word if any
values other than those listed above are specified. The setting will be inval-
id.
2. Automatically written to EEPROM when the parameter setting is changed.
3. Set up the system to ensure that EEPROM is not written to more than
100,000 times.
4. The decimal point will be adjusted if the range is changed to another range
with a different number of decimal places. Adjust the setting as necessary
after changing ranges. (Example: If a 0.01
°
C range is changed to a 0.1
°
C
range and the input shift value was 0.05
°
C, the setting would be changed to
0.5
°
C.
5. Heater burnout detection will not be performed if the alarm setting is 0.0 or
50 A. The heater burnout alarm output will turn OFF if the setting is changed
to 0.0 A and will turn ON if the setting is changed to 50 A.
6. The current manipulated variable will be monitored.
7. The initial manual manipulated variable will be set to maintain the output lev-
el before Manual Mode was entered.
8. Always check the “Write Completed Flag” to be sure that the write to
EEPROM has been completed when setting a parameter that is stored in
EEPROM. A minimum of 60 ms is required to complete writing to EEPROM.
