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

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].

Functions

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. Ex) If actual temperature is 80℃ but controller displays 78℃, set input correction value [IN-B] as ‘2’ and controller displays 80℃.

• 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[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 these values. Current temperature may be different by actual input value.

SSR drive output method (SSRP function)[SSrM]

• SSRP function is selectable one of standard ON/OFF control, cycle control, phase control by utilizing standard SSR drive output.
• This function parameter appears only in SSR drive output model (TX4 – 4S).
• Realizing high accuracy and cost effective temperature control with both current output (4-20mA) and 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 a zero cross turn-on SSR or random turn-on SSR. For phase control, connect random turn-on SSR.
  

When selecting cycle or phase control mode, the power supply for a load and a temperature controller must be the same. Control cycle[T] is able to set only when control method[C-MD]of parameter group 2 is set as PID and SSR drive output method [SSrM] is set as STND In case of selectable current output or SSR drive output model(TX4 – 4C), this parameter does not appear. Standard ON/OFF control by SSR is only available.

1. Standard ON/OFF control [STND] Controls ON (100% output)/OFF (0% output) as same as standard relay output.
   

2. Cycle control [CYCL] Controls the load by repeating output ON / OFF according to the rate of output within setting cycle based on certain period (50-cycle). Control accuracy is almost the same with phase control’s. This control has improved ON/ OFF noise than phase control’s due to zero cross type which turns ON/OFF at zero point of AC.
   
   

3. Phase control [PHAS] Controls the load by controlling the phase within AC half cycle.Serial control is available. Must use random turn-on SSR for this mode.
   
   

Current output range[oMA] : In case of selectable current output or SSR drive output model(TX4S- 4C), when control output [OUT] parameter 2 group is set as [CURR], you can select high/low-limit range, 4-20mA [4-20] or 0-20mA [0-20] of current output.

Hysteresis[HYS] : Set interval between ON and OFF of control output for ON/OFF control.

• If hysteresis is too narrow, hunting(oscillation, chattering) could occur due to external noise.
• In case of ON / OFF control mode, even if PV reaches stable status, there still occurs hunting. It could be due to hysteresis [HYS] setting value, load’s response characteristics or sensor’s location. In order to reduce hunting to a  minimum, it is required to take into following factors consideration when designing temp. controlling; proper Hysteresis [HYS], heater’s capacity, thermal characteristics, sensor’s response and location.
  

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.

Start control to 1 : When control output MV is 100%, PV is increased over than LBA detection band [LBaB] during LBA monitoring time [LBaT].
1 to 2 : The status of changing control output MV (LBA monitoring time is reset.)
2 to 3 : 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.
3 to 4 : Control output MV is 0% and loop break alarm (LBA) turns and maintains ON.
4 to 6 : The status of changing control output MV (LBA monitoring time is reset.)
6 to 7 : 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.
7 to 8 : 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.
8 to 9 : 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.
