1. I n i t i a l s e t m o d e c h a n g i n g
1.1 Entering the initial set mode
(1) Press the key to display the set data locking parameter
symbol on the measured-value (PV) display unit.
At this time, the least significant digit on the set-value (SV)
display unit lights brightly. The digit which lights brightly is
settable.
(2) Press the key to shift the digit which lights brightly up to
the hundreds digit. The digit which lights brightly shifts as
follows every time the key is pressed.
(3) Press the key to set “ ”. Pressing the key increments
numerals, and pressing the key decrements numerals.
:No initial set mode locked
(4) Hold both the (A) and (B) keys simultaneously
until appears.
Cautions
1. In order to enter the initial set mode, always set the data locking
to “ ”. Any setting other than “ ”
cannot enter the initial set mode.
2. If the controller is set to the initial set mode, all outputs are turned OFF.
3. An example of the REX-C900 is described here, but the same procedure applies to other
controllers (REX-C100, -C400, -C410, and -C700).

-2-
1.2 Exiting the initial set mode
(1) Exits from the initial set mode
Keep pressing both the key (A) and (B) keys simultaneously for more than 5 seconds can enter the
PV/SV display mode.
‰Even if the controller exits from the initial set mode at any point, the setting mode so far set becomes valid.
(2) Locks the initial set mode (Change the content of set data lock setting)
1. Press the key to enter the parameter setting mode.
2. Press the key by required number of times to show “ ” on the measured-value (PV) display
unit.
3. Press the key and keys to set “ ”. Press the key to register “ ”.
Caution
If the controller exits from the initial set mode, confirm that set data lock setting is set to “ ”.
< Each status when power failure occurs in the initial set mode >
•Setting prior to power failure is valid
•Instantaneous power failure (within 20 msec.) does not exert bad influence on the instrument.
•If long power failure occurs, the instrument exits from its initial set mode. After power recovery, the instrument
is set to the PV/SV display mode. The measured-value (PV) at this time shows that at the time of power
recovery, and the set-value (SV) is the same as that before power failure.

2.2 Each parameter setting
uMethod of setting
(2) Press the key to display the input type selection parameter
symbol ( ) on the measured-value (PV) display unit.
At this time, the least significant digit on the set-value (SV)
display unit lights brightly. The digit which lights brightly is
settable.

the tens digit. The digit which lights brightly shifts as follows
every time the key is pressed.
(4) Press the key to set “ ”. Pressing the key increments
numerals, and pressing the key decrements numerals.
:Thermocouple type L
(5) After finishing the setting, press the key to
register (shifts to next parameter).
Cautions
1. If no key operation is performed for more than 60 sec. during setting or when any
parameter other than
