Parameter 2group

SV setting
You can set the temperature to control with , , , keys. The setting range is within SV lower limit value [L-SV] to SV higher limit value [H-SV].
E.g.) In case of changing set temperature from 210ºC to 250ºC

Parameter reset
Reset all parameters as factory default. Hold the front + + keys for 5 sec., to enter parameter reset [INIT] parameter. Select ‘YES’ and all parameters are reset as factory default. Select ‘NO’ and previous settings are maintained. If setting parameter lock [LOC] or processing auto-tuning, parameter reset is unavailable.

Functions

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.)

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 is displayed.) If hysteresis is too small, it may cause control output hunting (takeoff, chattering) by external noise, etc.

SSR drive output selection(SSRP function) [SSrM]

• SSRP function is selectable one of standard ON/OFF control, cycle control, phase control by utilizing standard SSR drive output.
• Realizing high accuracy and cost effective temperature control as linear output(cycle control and phase control).
• Select one of standard ON/OFF control [STND], cycle control [CYCL] , phase control [PHAS] at [SSrM] parameter of parameter 2 group. For cycle control, connect zero cross turn-on SSR or random turn-on SSR. For phase control, connect random turn-on SSR.

Temperature controller

• When selecting phase or cycle control mode, the power supply for load and temperature controller must be the same.
• In case of selecting PID control type and phase [PHAS] / cycle [PHAS] control output modes, control cycle [T] is not allowed to set.
• For AC/DC power model (TCN -22R), this parameter is not displayed and it is available only standard control by relay or SSR.

1. Standard ON/OFF control mode [STND] A mode to control the load in the same way as Relay output type. (ON: output level 100%, OFF: output level 0%)

2. Cycle control mode [CYCL]
   A mode to control the load by repeating output ON / OFF according to the rate of output within setting cycle. Having improved ON / OFF noise feature by Zero Cross type.

3. Phase control mode [ PHAS]
   A mode to control the load by controlling the phase within AC half cycle. Serial control is available. RANDOM Turn-on type SSR must be used for this mode.

Digital input key ( 3sec.) [ ]

Alarm

Set both alarm operation and alarm option by combining. Alarm outputs are two and each one operates individually. When the current temperature is out of alarm range, alarm clears automatically. If alarm option is alarm latch or alarm latch and standby sequence 1/2, press digital input key( 3 sec., digital input key[ ] of parameter 2 group set as AlRE), or turn OFF the power and turn ON to clear alarm.

Alarm operation

• H: Alarm output hysteresis[AHYS]

Alarm opetion

• 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.

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 [5BaB].

Loop break alarm(LBA)
It checks control loop and outputs alarm by the 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 [ ] during LBA monitoring time [ ], or when control output MV is 0%(100% for cooling control) and PV is not decreased below than LBA detection band [ ] during LBA monitoring time [ ], alarm output turns ON.

• 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 [ ] parameter is displayed.

Manual reset[ ]

• Manual reset [ ****] by control result

When selecting P/PD control mode, certain temperature difference exists even after PV reaches stable status because 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 and manual reset [ ****] function is to set/correct offset. When PV and SV are equal, reset value is 50.0%. After control 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%.

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’.

Input digital filter[ ]
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.

Error

Check input sensor state.
HHHH| Flashes if measured sensor input is higher than temperature range.| When input is within the rated temperature range, this display disappears.
LLLL| Flashes if mesured sensor input is lower than temperature range

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 the 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 the power line and input signal line closely, use line filter or varistor at the power line and shielded wire at input signal line. Do not use near equipment which generates strong magnetic force or high-frequency noise.
4. Install a power switch or circuit breaker in an easily accessible place for supplying or disconnecting the power.
5. Do not use the unit for another purpose (e.g. voltmeter, ammeter), but for temperature controller.
6. When changing the input sensor, turn off the power first before changing it. 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 the radiation of heat. For accurate temperature measurement, warm up the unit over 20 min after turning on the power.
9. Make sure that the power supply voltage reaches to the rated voltage within 2 sec after supplying power.
10. Do not wire to terminals that are not used.
11. This unit may be used in the following environments.
12. Indoors (in the environment condition rated in ‘Specifications’)
13. Altitude max. 2,000m
14. Pollution degree 2
15. Installation category II
