Data Ranges Section 2-6
Note 1. If a setting is out-of-range, the Setting Error Flag will be turned ON and the
incorrect setting will be identified by the Setting Error Number. (The incor-
rect setting will be invalid and the Temperature Control Unit will operate
with the previous setting.)
2. When a loop’s Save Bit is turned ON, that loop’s settings will be saved to
the Temperature Control Unit’s EEPROM.
3. Do not write the settings to EEPROM more than 100,000 times.
4. The Heater Burnout Detection function will be disabled if the Heater Burn-
out Current is set to 0.0 A or 50.0 A. The HB Alarm Output will be OFF
when the HB Current is set to 0.0 A; it will be ON when the HB Current is
set to 50.0 A.
2-6-2 Monitored Values
Note 1. The Manipulated Variable Monitor indicates the manipulated variable that
is presently being output.
When ON/OFF control is being used, this value will be 100% for ON and
0% for OFF.
2. If the heater current exceeds 55.0 A, the monitor value will indicate CCCC.

Period 0001 to 0099 0001 to 0063 Sec-
onds 20 The Temperature Con-
trol Unit’s settings are
written to RAM. When
the Save Bit is turned
ON, the settings are
written to EEPROM.
(See notes 2 and 3.)
If DIP switch pin 8 is
ON, the settings are
automatically trans-
ferred from EEPROM
to the CPU Unit when
the power is turned
ON or the Tempera-
ture Control Unit is
restarted.
