Event output (ML-E) is not included in maximum connection quantity, and only one Unit is connected during module composition and used.

■ Product run through communications connection

For RS232C and RS485 communications method, this product supports PC-Link, PC-Link with SUM, Modbus, ASCII/RTU protocols. Through individual communication with product, it is operated with reading/writing of Register address defined based on function. Basic functions such as control and monitoring can be tested or operated using operating program provided in the computer. RS485 communications : For use, connect to communications terminal at low part, and this standard is used when operating multiple units since communications are achieved only through address set as switch in front side. RS232C communications : For use, connect to Loader Jack at front part, and only connected unit is communicated regardless of front side switch setup. It is for unit’s initial setting.

■ Input type

Thermocouple (12 types) : K, J, E, T, R, B, S, L, N, U, W, PL2 RTD (2 types) : Pt100, KPt100 DC voltage (3 types) : 0 – 10 V, 1 -5 V, 0 – 100 mV Direct current (4 – 20 mA) : Set input type as direct current (1 -5 V), attach 250 Ω of electric resistance at both ends of input terminal Current Transformer (CT) : 2 channel, AC 1 – 50A (primary current measuring range), apply only to ML-D2H

■ Control output type

Depending on output type of model composition, fixed in one among REALY, voltage pulse (SSR), and

Multi Loop Controller

current output (SCR).

■ Control method 2 DOF (Degree of Freedom) PID control (auto tuning support), ON/OFF control ML-D2H: 2 Channel, Universal control (Selectable Heating or cooling control) or Heating/Cooling simultaneous controlling ML-D4: 4 Channel, Universal control (Selectable Heating or cooling control)

3.3. Manipulation and run

3.3.1 Input section

● Input type (INP)

It is a parameter setting input signal (sensor) type, and once this input type is set, input scope (range) and decimal point indication or not is determined depending on the type of input. Input type can be set differently by channel. All parameters related to PV are initialized when changing input type.

● Input correction (BS)

Parameter to be set when temperature correction to Process value (PV) is required Reading can be expressed as addition of reading before input correction and set value of input correction.

● Input filter (FL)

Parameter to remove noise when it comes in to Process value (PV) repetitively. Noise not only impairs control feature, but also causes surge in manipulated value. However, if input filter is set large, actual reading is expressed with time delay.

● Reference junction compensation (RJC)

When using temperature sensor as TC, as a principle, PV is expressed by correcting standard contact point correction. To verify TC and RJC individually, corresponding parameter can be used.

● Limit to Set value (SV) by Set Value High (SVH) and Set Value Low (SVL)

SV is limited by SVH and SVL. Limited set value can be changed within the range of input type.

● Limit to Process value by Full Range High (FRH) and Full Range Low (FRL)

Set High and Low range of process value (PV). If it is out of the set range, OVER of alarm group 1 of CHESTS (channel status) is occurs. The control is operating normally.

● Input scale range high (SLH) / scale range low (SLL) setting

It applies only if input type is set to voltage input (DCV). The input range of PV is adjusted to the high limit or low limit of set scale.

● Parameter setting lock (LOCK)

This is a parameter that prohibits parameter setting.

LOCK set value Details

1 Possible to set only SV, R/S, AT, CHEN parameters

All parameters settings are impossible, but LOCK parameter is possible to set.

3.3.2 Control section

● Channel mode (CHMD)

Channel mode consists of 3 types including “stop mode”, “monitor mode”, and “run mode” and different setting for each channel is possible.

●

Setting are completed at channel mode (CHMD) parameter, run status at each channel mode

is as follows.

Channel mode

Stop mode Control run (X), Even occurrence (X) Control run (X), Even occurrence (X)

Monitor mode Control run (X), Even occurrence (O) Control run (X), Even occurrence (O)

Run mode Control run (O), Even occurrence (O) Control run (X), Even occurrence (O)

※ Run mode, if in run stop status, it functions similarly as the monitor mode. This status is called READY state.

● Run setting (R/S) and run setting state saving (R/S_S)

If “1(ON)” is set to run setting (R/S), it becomes “run start (RUN)” state, and all channels with channel mode set to “run mode” start control runs, and if “0(OFF)” is set to run setting (R/S), it becomes “run stop (STOP)” state, and all channels terminate control run. Also, as run setting save option can be set at R/S_S parameter, when power is first supplied, this run setting state can be maintained or set as “run stop (STOP)” state.

● Direction (DR)

This parameter is to set control run of each channel, and can be set at forward run or reverse run. When using as heating /cooling control by setting H/C parameter to “1”, control run (DR) setting is disregarded

3.3.2 Heating, heating/cooling control (HC)

Control method can be set at heating control or heating/cooling control. If heating/cooling control is set, control output is divided into 2 signals, one for heating and one for cooling. For control method, heating and cooling can be set as PID control or ON/OFF control respectively for output. If heating side proportional band (PB) is set to “0oC”, heating side is controlled as ON/OFF control output, and if cooling side proportional band (PBC) is set to “0oC”, cooling side is controlled as ON/OFF control output,

3.3.2 Dead band of heating/cooling control (HC_DB)

Upon heating/cooling control, dead band of heating side and cooling side manipulated value can be set up. For ON/OFF control, dead band of both heating side and cooling side is as follows.

● Proportional Band (PB), Integral Time (TI), Differential time (TD)

Constant to control PID. These parameters are set up automatically if auto tuning (AT) is performed

● Auto tuning (AT)

Normally, for 2 DOF P.I.D control, Values of P.I.D constants such as proportional band (PB), integral time (TI), differential time (TD) should be set to targeted temperature value of equipment to be controlled, and proper values be applied. If auto tuning (AT) parameter is set to “1”, P.I.D constants is automatically set up after pre-set control run is performed, and after AT parameter is changed to “0”, P.I.D constant value applied control starts. If auto tuning (AT) parameter is set to “1”, corresponding channel mode is changed to run mode, run setting (R/S) is set to “1”, and it becomes run start (RUN) state.

● Output cycle (CT)

A cycle that becomes ON and OFF of RELAY or voltage pulse (SSR) output is called “output cycle” and can be set at CT parameter. For RELAY output, if output cycle is set short, it can show quick responses, but lifespan is shortened. Thus, setting output cycle less than 20 seconds is not recommended.

● 2 DOF PID Alpha (AP)

Response in general closed loop control system can be mainly divided into response to set value change and response to disturbance, and existing PID (1 DOF) algorithm is limited to optimize only one response for these two responses. 2 DOF algorithm was applied to overcome this limitation, and response optimization to set value change and appropriate response to disturbance can be obtained. Alpha (AP) parameter set value (SV) is used for adjusting response feature to set value (SV).

● Ramp function (RATE)

It refers to the inclination that reaches set value (SV) after change from set value (SV) before change, temperature value set at RTUP (SV increasing temperature), RTDN (SV decreasing temperature) set value can have inclination of (temperature value / time), and be increased or decreased based on time set at RTMIN(SV transit time (min.)), RTHRS(SV transit time (hour)). Set value that changes based on time can be verified with current target set value (TSV) parameter. Upon executing auto tuning (AT), ramp function stops, and auto tuning is performed using the last set value (SV).

● Event channel (EVCH) and event bus output (EVBUS)

Maximum of 8 channels by input channel are provided, and each can be set with different event type (EVT) and set value (EV). However event channel with event bus output is limited to 8 channels. Upon occurrence of set event, event (EV) LED of front section is turned on, event state (EV_STS) parameter is set to “1”. Event occurrence can be verified at event channel state (EVSTS. [1-4]) parameter by input channel, and at input channel state (EV.[1-8]) parameter by event channel. If event occurs only with event channel that EVBUS.[1-8] parameter is set to “1”, event bus is used for output.
