3-2 Selecting the Temperature Units
The Temperature Control Unit can operate in
°
C or
°
F. Select the desired tem-
perature units with pin 2 of the DIP switch on the front of the Unit.
The temperature unit setting applies to all of the Unit’s control loops. It is not
possible to set different temperature unit settings for the control loops.
3-2-1 Temperature Unit Setting (Pin 2)
The factory setting is OFF (
°
C), as shown by the shading in the diagram above.
If this setting is changed, the new setting will not become effective until the
power is turned ON or the Unit is restarted.
3-3 Setting the Data Format
A switch on the front of the Unit (pin 3 of the DIP switch) selects whether the
Temperature Control Unit’s data is handled as 4-digit BCD or binary (i.e., 4-digit
hexadecimal.) This switch setting controls the data format for both user-set and
system-set data stored in the words allocated in the memory areas (CIO and
DM Areas) used to exchange data between the CPU Unit and Temperature
Control Unit.
3-3-1 Setting the Data Format (Pin 3)
Selecting Binary
Format
The factory setting is OFF (4-digit BCD), as shown by the shading in the dia-
gram above.
If this setting is changed, the new setting will not become effective until the
power is turned ON or the Unit is restarted.
