System Configuration Section 1-2
Once the settings have been stored in the Temperature Control Unit and the
Unit is set for automatic transfer, the Unit will always start with those settings
whether the power has been turned OFF or not. (The settings can be changed
after startup if necessary.)
To simplify Temperature Control Unit operation, pin 8 on the DIP switch can be
turned ON to enable operation by merely turning ON the power supply and
setting Operation Data (the SP). All other settings can be used at their default
values. (Refer to
2-6-1 Settings for the default settings.)
1-2 System Configuration
1-2-1 Basic System Configuration
The following diagram shows a basic system with a CJ1W-TC001 Tempera-
ture Control Unit (4 control loops, thermocouple inputs, and NPN outputs) and
a CJ1W-TC103 Temperature Control Unit (2 control loops with heater burnout
detection, platinum resistance thermometer inputs, and NPN outputs).
Note 1. An OMRON E54-CT1 or E54-CT3 Current Transformer must be used as
the Current Transformer (CT). Do not use any other Current Transformer.
2. Turn ON the Stop Bit for the loop to stop temperature control. If PID control
is being used and the heater is turned OFF using an operation switch input
to the heater, PID control performance will be adversely affected.
1-2-2 Mounting the Unit
The CJ1W-TC @@@ Temperature Control Units are CJ-series Special I/O
Units, so they can be mounted in a CJ-series CPU Rack or Expansion Rack.
