• No water, oil or chemicals or where the vapors of these substances can come into direct contact with the unit

• Take note that the ambient temperature of this unit must not exceed 50 (122 ) if mounted through the face of a control panel. Otherwise the life of electronic components (especially electrolytic capacitors) may be shortened.

Note • Avoid setting this instrument directly on or near lammable material even though the case of 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 the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the

ACS-13A.

• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be inserted from the left side of the terminal, and fastened with the terminal screw.

• Tighten the terminal screw to within the specified torque. If excessive force is applied to the screw when tightening, the terminal screw or case may be damaged.

• When using a terminal cover, pass terminal wires numbered 7 to 12 into the holes of the terminal cover.

• This instrument does not have a built-in power switch, circuit breaker or fuse.

It is necessary to install them near the controller.

(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)

• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).

• 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.

• Use a thermocouple and compensating lead wire according to the sensor input specifications of this controller.

• Use the 3-wire RTD according to the sensor input specifications of this controller.

• (+) side input terminal number of 0 to 5V DC, 1 to 5V DC, 0 to 10V DC differs from that of 0 to 1V DC.

(+) side input terminal number of 0 to 5V DC, 1 to 5V DC, 0 to 10V DC: 9

(+) side input terminal number of 0 to 1V DC: 10

• When using a relay contact output type, externally use a relay according to the capacity of the load to protect the built-in relay contact.

• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires to avoid external interference.

3. Operation and maintenance precautions

Caution

• It is recommended that auto-tuning (AT) be performed on the trial run.

• Do not touch live terminals. This may cause electric shock or problems in operation.

• Turn the power supply to the instrument OFF when retightening the terminal or cleaning.

Working on or touching the terminal with the power switched ON may result in severe injury or death due to Electric Shock.

• Use a soft, dry cloth when cleaning the instrument.

(Alcohol based substances may tarnish or deface the unit.)

• As the display section is vulnerable, do not strike or scratch it with a hard object or press hard on it.

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 not concur 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.

10. AT (Auto-tuning)

In order to set each value of P, I, D and ARW automatically, the AT process should be made to fluctuate to obtain an optimal value. One 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 [1], [2] and [3] below.

Notice

• Perform the AT during the trial run.

• During the AT, none of the setting items can be set.

• If power failure occurs during the AT, the tuning stops.

• Sometimes the AT process will not fluctuate if AT is performed at or near room temperature.

Therefore AT might not finish normally.

Attached functions:

[Power failure countermeasure]:

The setting data is backed up in the non-volatile IC memory.

[Self-diagnosis]:

The CPU is monitored by a watchdog timer, and if the CPU’s status becomes abnormal, the controller is switched to warm-up status with all outputs OFF.

[Automatic cold junction temperature compensation] (Only thermocouple input type)

This detects the temperature at the connecting terminal between the thermocouple and the instrument, and always maintains it at the same status as if the reference junction location temperature was at 0 (32 ).

[Warm-up indication]

After the power supply to the instrument is turned on, the PV display indicates the sensor input type, and SV display indicates input range high limit value (for thermocouple, RTD) or Scaling high limit value (for DC input) for approximately 3 seconds.

[Indication range and Control range]

Thermocouple input: [Input range low limit value – 50 (100 )] to [Input range high limit value + 50 (100 )]

RTD input: [Input range low limit value -Input span x 1%] to [Input range high limit value + 50 (100 )]

DC current, voltage input:

[Scaling low limit value -Scaling span x 1%] to [Scaling high limit value +Scaling span x 10%]

[Burnout]

When the thermocouple or RTD input is burnt out, OUT1 and OUT2 are turned OFF (for DC current output type, OUT1 low limit value) and the PV display flashes “ ”.

However, for the manual control, the preset MV (manipulated variable) is outputted.

When the DC current or voltage input is disconnected, PV display flashes “ ” for 4 to 20mA DC and 1 to 5V DC inputs, and “ ” for 0 to 1V DC input. For 0 to 20mA DC, 0 to 5V DC and 0 to 10V DC inputs, the PV display indicates the value corresponding with 0mA or 0V input.

Set value lock

• (Unlock): All set values can be changed.

(Lock 1): None of the set values can be changed.

(Lock 2): Only main setting mode can be changed.

(Lock 3): All set values except Input type can be changed.

However, changed values revert to their previous value after power is turned off because they are not saved in the non-volatile memory. Do not change any setting item in

Setup mode. If any item in Setup mode is changed, it will affect other setting items such as the SV and Alarm value.
