Functions

1. Auto tuning [AT]

Auto tuning measures the control subject’s thermal characteristics and thermal response rate, and then

determines the necessary PID time constant. (When control type[C-MD] is set as PID, it is displayed.)

Application of the PID time constant realizes fast response and high precision temperature control.

If error [OPEN] occurs during auto tuning, it stops this operation automatically. To stop auto tuning,

change the set as [OFF]. (It maintains P, I, D values of before auto tuning.)

2. Hysteresis [HYS] In case of ON/OFF control, set between ON and OFF intervals as hysteresis. (When control type [C-MD] is set as ONOF, it

Description

AM .A

Standard alarm

If it is an alarm condition, alarm output is ON. If it is a clear alarm condition, alarm output is OFF.

AM .B

Alarm latch

If it is an alarm condition, alarm output is ON and maintains ON status. (Alarm output HOLD)

AM .C

Standby sequence 1

First alarm condition is ignored and from second alarm condition, standard alarm operates. When power is supplied and it is an alarm condition, this first alarm condition is ignored and from the second alarm condition, standard alarm operates.

Alarm latch If it is an alarm condition, it operates both alarm latch and standby sequence. When AM .D and standby power is supplied and it is an alarm condition, this first alarm condition is ignored and
sequence 1 from the second alarm condition, alarm latch operates.

AM .E

Standby sequence 2

First alarm condition is ignored and from second alarm condition, standard alarm operates. When re-applied standby sequence and if it is alarm condition, alarm output does not turn ON. After clearing alarm condition, standard alarm operates.

AM .F

Alarm latch and standby sequence 2

Basic operation is same as alarm latch and standby sequence1. It operates not only by power ON/OFF, but also alarm setting value, or alarm option changing. When re-applied standby sequence and if it is alarm condition, alarm output does not turn ON. After clearing alarm condition, alarm latch operates.

Condition of re-applied standby sequence for standby sequence 1, alarm latch and standby sequence 1: Power ON

Condition of re-applied standby sequence for standby sequence 2, alarm latch and standby sequence 2: Power ON,

changing set temperature, alarm temperature (AL1, AL2) or alarm operation (AL-1, AL-2), switching STOP mode

to RUN mode.

3)Sensor break alarm The function that alarm output will be ON when sensor is not connected or when sensor’s disconnection is detected during temperature controlling. You can check whether the sensor is connected with buzzer or other units using alarm output contact. It is selectable between standard alarm [SBaA] or alarm latch [SBaB]. 4)Loop break alarm(LBA) It checks control loop and outputs alarm by temperature change of the subject. For heating control(cooling control), when control output MV is 100%(0% for cooling control) and PV is not increased over than LBA detection band [LBaB] during LBA monitoring time [LBaT], or when control output MV is 0%(100% for cooling control) and PV is not decreased below than LBA detection band [LBaB] during LBA monitoring time [LBaT], alarm output turns ON.

Time

Start control When control output MV is 100%, PV is increased over than LBA detection band [LBaB] during

LBA monitoring time [LBaT].

The status of changing control output MV (LBA monitoring time is reset.)

When control output MV is 0% and PV is not decreased below than LBA detection band [LBaB] during LBA monitoring time [LBaT], loop break alarm (LBA) turns ON after LBA monitoring time.

Control output MV is 0% and loop break alarm (LBA) turns and maintains ON.

The status of changing control output MV (LBA monitoring time is reset.)

When control output MV is 100% and PV is not increased over than LBA detection band [LBaB] during LBA monitoring time [LBaT], loop break alarm (LBA) turns ON after LBA monitoring time.

When control output MV is 100% and PV is increased over than LBA detection band [LBaB] during LBA monitoring time [LBaT], loop break alarm (LBA) turns OFF after LBA monitoring time.

The status of changing control output MV (LBA monitoring time is reset.)

When executing auto-tuning, LBA detection band[LBaB] and LBA monitoring time are automatically set based on auto tuning value. When alarm operation mode [AL-1, AL-2] is set as loop break alarm(LBA) [LBa ], LBA detection band [LBaB] and LBA monitoring time [LBaT] parameter is displayed.

7. Manual reset[REST]

·Manual reset [REST] by control result

When selecting P/PD control mode, certain temperature difference exists even after PV reaches stable status because

Set below 50.0 as reset value

heater’s rising and falling time is inconsistent due to thermal

characteristics of controlled objects, such as heat capacity,

heater capacity. This temperature difference is called offset

Offset Offset

and manual reset [REST] function is to set/correct offset. When PV and SV are equal, reset value is 50.0%. After control

Set over 50.0 as reset value

is stable, PV is lower than SV, reset value is over 50.0% or PV is higher than SV, reset value is below 50.0%.

Measured value

8. Input correction[IN-B]

Controller itself does not have errors but there may be error by external input temperature sensor.

This function is for correcting this error.

E.g.) If actual temperature is 80ºC but controller displays 78ºC, set input correction value [IN-B] as

‘002’ and controller displays 80ºC.

As the result of input correction, if current temperature value (PV) is over each temperature range

of input sensor, it displays ‘HHHH’ or ‘LLLL’.

9. Input digital filter[MAvF] If current temperature (PV) is fluctuating repeatedly by rapid change of input signal, it reflects to MV

and stable control is impossible. Therefore, digital filter function stabilizes current temperature value. For example, set input digital filter value as 0.4 sec, and it applies digital filter to input values during 0.4

sec and displays this values. Current temperature may be different by actual input value.

Cautions during Use

1. Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected accidents.

2. Check the polarity of the terminals before wiring the temperature sensor.

For RTD temperature sensor, wire it as 3-wire type, using cables in same thickness and length.

For thermocouple (CT) temperature sensor, use the designated compensation wire for extending wire.

3. Keep away from high voltage lines or power lines to prevent inductive noise.

In case installing power line and input signal line closely, use line filter or varistor at power line and

shielded wire at input signal line.

Do not use near the equipment which generates strong magnetic force or high frequency noise.

4. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting

the power.

5. Do not use the unit for other purpose (e.g. voltmeter, ammeter), but temperature controller.

6. When changing the input sensor, turn off the power first before changing.

After changing the input sensor, modify the value of the corresponding parameter.

7. 24VAC, 24-48VDC power supply should be insulated and limited voltage/current or Class 2, SELV

power supply device.

8. Make a required space around the unit for radiation of heat.

For accurate temperature measurement, warm up the unit over 20 min after turning on the power.

9. Make sure that power supply voltage reaches to the rated voltage within 2 sec after supplying power.

10. Do not wire to terminals which are not used.
