Note: Avoid setting this instrument directly on or near flammable material even though the caseof this instrument is made of flame-resistant resin.

2. Wiring Precautions
Caution• Do not leave wire remnants in the instrument, because they could cause a fire or malfunction.
• Use correct fitting ferrules with an insulation sleeve for the terminal screw when wiring the DCL-33A.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw whentightening, the terminal screw or case may be damaged.
• Do not apply a commercial power source to the sensor which is connected to the input terminal nor
allow the power source to come into contact with the sensor.
• This instrument does not have a power switch, circuit breaker and fuse. Therefore it is necessary to
install a power switch, circuit breaker and fuse externally near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For a 24 V AC/DC power source, do not confuse polarity when using direct current (DC).

17Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at the exact location wherecontrol is desired, the sensor-measured temperature may deviate from the temperature in the controlled
location.
When using multiple controllers, sometimes the measured temperatures (input value) do not match(even if SV is the same value) 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.
PV after sensor correction = Current PV + (Sensor correction value)
Loop break alarm
The alarm will be activated if the PV (process variable) does not reach the Loop break alarm bandsetting within the time allotted to assess the Loop break alarm after the MV (manipulated variable) has
reached 100% or the control output high limit value. The alarm will also be activated if the PV (process
variable) does not drop to the Loop break alarm band setting within the time allotted to assess the Loop
break alarm after the MV has reached 0% or the control output low limit value.
When the control action is Direct (Cooling), read “drop to” for “reach” and vice versa.
Energized/De-energized[If alarm action Energized is selected]

6. Simplified Converter Function
Caution• The converter function is selectable only for the Direct current output type.
• 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 to controller function, the control parameters and values set
by converter function are retained even if the function is switched to controller function.
So, after switching to the controller function, correct the converter parameters to thecontroller parameters.

The converter function of this instrument converts each input (thermocouple, RTD, DC voltage and direct
current inputs) value to “4 to 20 mA 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 below.
After steps (1) to (7) are finished, this instrument can be used as a converter.
(1) Wire this unit (Power supply, Input and Output).
(2) Turn the power supply of this unit ON.
and(3) Enter ‘Auxiliary function setting mode 2’ by pressing the).
(4) Select a sensor type in [Input type] ((5) Set the high limit of the value to be converted in [Scaling high limit] ((6) Set the low limit of the value to be converted in [Scaling low limit] () in [Controller/Converter] ()”.
(7) Select Converter (key (for approx. 3 seconds).

Input, output conditions
Input: 6 to 14 mA DC (Indication: 30.0 to 130.0)
Output: 4 to 20 mA DC
Setting method(1) Calculating Scaling high and low limit value of 4 to 20 mA DC
Indication value per mA DC: (130.0 – 30.0) ÷ (14 – 6) = 100 ÷ 8 = 12.5
Scaling high limit value: 130.0 + (20 – 14) x 12.5 = 205.0
Scaling low limit value: 30.0 – (6 – 4) x 12.5 = 5.0(2) Calculating OUT proportional band of 6 to 14 mA DC
OUT proportional band (P) = {(14 – 6) ÷ (20 – 4)} x 100 = 0.5 x 100 = 50(%)(3) Calculating SV so that output can become 4 mA DC from 6 mA DC input (Parallel shiftsetting)

9. AT (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.
One of 3 types of fluctuation below is automatically selected.
For DC 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 processing temperature as thetemperature is rising
When AT bias is set to 20 , the AT process will fluctuate at temperatures 20 lower than the SV.

There may be equipment thatinterferes with or makes noise near
the instrument.
The internal memory is defective.

Solution
How to check whether the input
signal wire is disconnected[DC voltage (0 to 5 V DC, 0 to 10 V
DC)]
If the input to the input terminal ofthis controller is 1 V DC, and if avalue (converted value from Scaling
high, low limit setting) corresponding to 1 V DC is indicated, thecontroller is likely to be operating
normally, however, the signal wire
may be disconnected.
[Direct current (0 to 20 mA DC)]If the input to the input terminal ofthis controller is 4 mA DC, and if
a value (converted value from
Scaling high, low limit setting) corresponding to 4 mA DC is indicated,the controller is likely to be
operating normally, however, thesignal wire may be disconnected.
Connect the signal wire to thecontroller input terminals securely.

Set the sensor input and thetemperature unit ( , ) correctly.
Set it to a suitable value.
Set the sensor specification properly.
Use an ungrounded type sensor.

alarm value, etc.) are
impossible.
• The values do notchange by theorkey.
The setting indication
does not change within
the rated input range
even if theor
key is pressed, and newvalues are unable to be
set.

Possible CauseSet value lock (Lock 1 or Lock 2) isselected.
Auto-tuning (AT) is performing.

Solution
Release the lock selection.

11.3 Control
Problem
The PV (temperature)
does not rise.

The control output
remains in an ON
status.
The control output
remains in an OFF
status.

Possible Cause
The sensor is out of order.
Check whether the sensor issecurely mounted to the instrument
input terminals, or control output
terminals are securely mounted
to the actuator input terminals.
Ensure that wiring of sensor
terminals or control output terminals
is correct.
OUT low limit value is set to 100%or higher in Auxiliary function
setting mode 2.
OUT high limit value is set to 0% orless in Auxiliary function setting
mode 2.
