4. Wiring
Warning
Turn the power supply to the instrument OFF before wiring or checking it.
Working or touching the terminal with the power switched ON may result in severe injury
or death due to Electric Shock.

Caution• Do not leave bits of wire in the DCL-33A when wiring, because they could cause fire or malfunction.
• Insert the connecting cable into the designated connector securely. Not doing so could cause
malfunction due to imperfect contact.
• Connect the AC power to the designated terminal as is written in this instruction manual. Otherwise it
may burn and damage the DCL-33A.
• Tighten the terminal screw with the specified torque. Excessive force could damage the terminal screw
and deface the case.
• Use a thermocouple and compensating lead wire that corresponds to the sensor input specification of this unit.
• Use the 3-wire RTD that corresponds to the sensor input specification of this unit.
• When using DC voltage and current inputs, be careful not to confuse polarity when wiring.
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• Keep input wires (Thermocouple, RTD, etc.) away from power source and load wires when wiring.
• Do not apply a commercial power source to the sensor connected to the input terminal nor allow thepower source to come into contact with the sensor.
• To prevent the unit from harmful effects of unexpected level noise, it is recommended that a surge
absorber be installed between the electromagnetic switch coils.
• This unit does not have a built-in power switch, circuit breaker or fuse. Therefore it is necessary to installthem in the circuit near the unit.
(Recommended fuse: Time-lag fuse, Rated voltage 250V AC, Rated current 2A)

This corrects the input value from the sensor. When a sensor cannot be set at the exact location where control
is desired, the sensor measured temperature may deviate from the temperature in the controlled location.
When controlling with plural controllers, sometimes the measured temperatures (input value) do notconcur due to differences in sensor accuracy or dispersion of load capacities. In such a case, the control
can be set at the desired temperature by adjusting the input value of sensors.
However, it is effective within the input rated range regardless of the sensor correction value.
[Loop break alarm]
The alarm will be activated when the PV (process variable) does not rise as much as the span or more
within the time it takes to assess the loop break alarm after the MV (manipulated variable) has reached100% or the output high limit value.
The alarm will also be activated when the PV (process variable) does not fall as much as the span ormore within the time it takes to assess loop break alarm after the MV (manipulated variable) has reached
0% or the output low limit value.
When the control action is Direct (Cooling), read “fall” for “rise” and vice versa.

7. Simplified converter function
Caution• When using this controller as a converter, take 1 second into consideration since input/output
response time is approx. 1 second.
• When switching from converter function to controller function, the control parameters and values
set by converter function are held even if the function is switched to controller function.
So, correct the control parameters and values which have been set by converter function to thevalues necessary for the controller function after switching to the controller function.
The converter function of this instrument converts each input (thermocouple, RTD, DC voltage and DC
current inputs) value to “4 to 20mA DC” using the control parameters of the controller, and outputs it.
When this instrument is used as a converter, follow steps (1) to (7) described on the next page.
After steps (1) to (7) are finished, this instrument can be used as a converter.

10. Auto-tuning

In order to decide each value of P, I, D and ARW automatically, the auto-tuning process should bemade to fluctuate to obtain an optimal value.
1 of 3 types of fluctuation below is automatically selected.
For DC voltage, current input, the AT process will fluctuate around the SV for conditions of (A), (B) and (C).
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or near room
temperature. Therefore auto-tuning might not finish normally.
(A) In the case of a large difference between the SV and PV (process variable) as the temperatureis rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.
