Chapter 1. GENERAL

1 - 1 Features

The DCP32 is:

• a general-purpose double-loop program controller for controlling temperature, pressure, flow rate and other inputs

• a 2-loop program controller for controlling temperature and relative humidity.

On the DCP32, you can set up to 19 program patterns, and set up to 30 segments to each program pattern.

● High accuracy achieved by multi-range input

Multi-range input allows you to choose between the following input types: thermocouple, resistance temperature detector (RTD), DC voltage and DC current. Accuracy of ±0.1%FS±1 digit (±0.2%FS±1 digit for Input 2 only) and a sampling cycle of 0.1 seconds ensures consistently high-precision control.

● Wide range of control output types

A wide range of models supporting various control output types are available: relay time-proportional output, position-proportional output, current output, voltage time-proportional output, and heat/cool output. On models other than heat-cool control output, you can also choose neural netbased auto-tuning and smart-tuning for inhibiting overshoot, in addition to 2 degrees of freedom PID.

● Enhanced compatibility with PLCs

12 external switch inputs (eight optional), three event outputs and five time event outputs (optional) ensure compatibility with automating systems designed around a PLC core.

● Easy operation

Up to eight frequently changed parameter setups can be registered to the PARA key, facilitating recall of item setups.

Chapter 4. WIRING

4 - 1 Wiring Precautions

WARNING

Before connecting the DCP32 to the measurement target or external control circuits, make sure that the FG terminal is properly grounded (100

Ω max.).

Failure to do so might cause electric shock or fire. Before wiring, be sure to turn the power OFF.

Failure to do so might cause electric shock. Do not touch electrically charged parts such as the power terminals.

Doing so might cause electric shock.

CAUTION

Do not allow lead clippings, chips or water to enter the DCP32 case. Doing so might cause fire or faulty operation.

Inputs to the current input terminals and on the DCP32 should be within the current and voltage ranges listed in the specifications. Failure to do so might cause fire or faulty operation.

Firmly tighten the terminal screws at the torque listed in the specifications. Insufficient tightening of terminal screws might cause electric shock or fire.

Do not use unused terminals on the DCP32 as relay terminals. Doing so might cause electric shock, fire or faulty operation.

We recommend attaching the terminal cover (sold separately) after wiring the DCP32. Failure to do so might cause electric shock.

Use the relays on the DCP32 within the service life listed in the specifications. Continued use of the relays after the recommended service life might cause fire or faulty operation.

Use Yamatake Corporation's SurgeNon if there is the risk of power surges caused by lightning. Failure to do might cause fire or faulty operation.

Chapter 4. WIRING

Handling Precautions

• Before wiring the DCP32, check the DCP32 model No. and terminal Nos. on the label on the rear of the body.

After wiring the DCP32, be sure to check the wiring for any mistakes before turning the power ON.

• Maintain a distance of at least 50 cm between I/O signal leads or communications leads and the power lead. Also, do not pass these leads through the same piping or wiring duct.

• When wiring with crimped terminals, take care to prevent contact with adjacent terminals.

• When connecting the DCP32's thermocouples in parallel to other controllers, make sure that the total input impedance of the other controllers is at least 1 MΩ.

If the input impedance is less than 1 MΩ, the DCP32 may not be able to detect sensor disconnection.

• Precautions when combining the DCP32 with other data input device When inputting the DCP32’s I/O (parallel connection in case of input) to

an A/D converter or analog scanner, read data may fluctuate. To prevent this, adopt one of the following measures.

①Use a low-speed, integrating type A/D converter. ②Insert an isolator without a switching power supply between the

DCP32 and A/D converter.

③Average the data on a personal computer when reading data. ④If possible, set a filter for the input.

• Provide a switch within the operator's reach on the instrumentation power supply wiring for turning the mains power OFF.

• Provide a delay-type (T) rated current 1A and rated voltage 250 V fuse on the instrumentation power supply wiring. (IEC 127)

4 - 2 Compensating Lead

When a thermocouple input is input to the DCP32, connect the bare thermocouple lead to the terminal. If the thermocouple is located a long way from the DCP32 or the thermocouple is connected to a terminal, extend the connection using a compensating lead and then connect to the terminal. Use shielded compensating leads only.

Note

• For I/O other than thermocouples, use JCS-364 shielded instrument polyethylene insulated vinyl sheath cable or equivalent product. (This is generally referred to “shielded twisted cable for instruments.”) The following cables are recommended.

• Shielded, multi-core microphone cord (MVVS) can be used if there is little electromagnetic induction.

The DCP32 is provided with four standard and eight optional external switch inputs. The optional eight inputs are located on the add-on terminal base. In this case, wire the external switch inputs across the standard and add-on terminal bases.

Handling Precautions

• The external switch inputs on the DCP32 have built-in power supplies (open voltage 12 Vdc). Be sure to use no-voltage contacts for external contacts.

• Use no-voltage contacts such as gold contacts whose small current can be switched ON/OFF. On some relay contacts, the small current cannot be switched ON/OFF. Use no-voltage contacts having a sufficient minimum switching capability with respect to the contact current and open voltage of the DCP32.

• When using a semiconductor (e.g. open-collector) as a no-voltage contact, use a semiconductor whose contact terminal voltages at contact ON are 3V max., and whose leakage current at contact OFF is 0.1 mA.

• External switch inputs on the DCP32, DCP31 and SDC40 series can be connected in parallel. When connecting in parallel with other controllers, thoroughly check the conditions of the other controller before configuring the control system.

5 - 2 Program Patterns

■ Patterns

SP1 (SP of CH1), SP2 (SP of CH2) and time comprise the settings for a single segment in a pattern.

Up to 30 segments can be linked to create a broken-line whose vertical axis is SP and horizontal axis is time.

This system is called the “RAMP-X” system. SP1 setting: Within range of SP1 limitter upper and lower limits SP2 setting: Within range of SP2 limitter upper and lower limits Time setting: 0 to 99 hours, 59 minutes or 0 to 99 minutes, 59 seconds

(Select the time unit in setup data

C64

SP is the point that corresponds to the time elapsed in the current segment on a straight line made by joining the start point (SP setting value of the previous segment) to an end point (SP setting value of the current segment). Accordingly, segments are categorized as follows:

• Rising ramp (rising ramp, rising tendency) Previous segment SP setting value < current segment SP setting value

• Falling ramp (falling ramp, falling tendency) Previous segment SP setting value > current segment SP setting value

• Soak (soak)

Previous segment SP setting value = current segment SP setting value

In the case of the No.1 segment, both the start and end points become the soak segment of the No.1 segment SP setting values. SP (other than No.1 segment) is calculated by the following formula: SP = (current segment SP setting value - previous segment SP setting value) x

(current segment elapsed time current segment time setting) + previous segment SP setting

Time setting is common to both SP1 and SP2.

Chapter 5. FUNCTIONS

■ Events 1 to 3

Events 1 to 3 are event configuration data. These are used after the event type, event standby, hysteresis and ON delay time are set. A total of three event types are available: PV type events, controller status events

and time events.

● PV type events

• Basic specifications The following page shows event type PV, deviation, absolute value deviation, SP, MV and MFB. In the figures, the thick lines show ON-OFF changes in state. The upper line expresses the ON state, and the lower line the OFF state. EV and H stand for event setting value and hysteresis, respectively. Output in the READY state is OFF.

• Event standby Events function as follows when event standby has been set to ON.

• If the DCP32 is in the state in the figure when changing from the READY

to the RUN mode and after restoring the power, operation is the same as when event standby is set to OFF. The up-facing arrow in the figure indicates a change to ON, and a down-facing arrow indicates a change to OFF.

• If the DCP32 is outside the state in the figure when changing from the

READY to the RUN mode and after restoring the power, the state is OFF. After entering the state, the up-facing arrow in the figure indicates a change to ON, and a down-facing arrow indicates a change to OFF.

• Event ON delay The event No. to apply the delay to and the delay time can be set regardless of event type. “Delay” functions to turn output ON when the event is continuously ON for the preset delay time after the event OFF → ON condition is satisfied. When event ON delay is combined with event standby, event standby must first be canceled before event ON delay functions.

• Segment progression

• Output is OFF until the program progresses to a segment containing the event

setting.

• When the program progresses to a segment containing an event setting, event

ON/OFF operation is carried out according to the event setting value.

• The previous setting is valid until the program progresses to a segment

containing a new event setting. Accordingly, set as follows to disable the event set to the preceding segment from a certain event onwards:

Direct action events: Upper limit value of event setting Reverse action events: Lower limit value of event setting

However, note that with some event types the event sometimes turns ON even if you set as shown above.

• When the program has progressed to the No.1 segment by the cycle or pattern link functions, the previous setting is disabled. Output is OFF unless the No.1 segment contains an event setting.

● Controller status events

Controller status events are turned ON and OFF according to the DCP32 mode, alarm status and other statuses. Though the event standby function does not function, the ON delay function does. Event setting values (operating point), hysteresis and event standby are not set.

• Basic operations The following event types are provided:

RUN+HOLD+FAST+END READY RUN HOLD FAST END G.Soak standby (logical OR of CH1 and CH2, CH1, CH2) MANUAL (logical OR of CH1 and CH2, CH1, CH2) Auto-tuning executing (logical OR of CH1 and CH2, CH1, CH2) Constant-value operation MFB estimated position control Logical OR of all alarms PV range alarm Controller alarms Low battery voltage Console setup in progress Loader setup in progress

ADV When the DCP32 reaches the state designated by the event type, the event is turned ON. Otherwise, the event is OFF.

• Alarms Alarms are divided into the PV range alarm group (alarm code Nos. 01 to 16) and the controller alarm group (alarm code Nos. 70 to 99, and low battery voltage). When the event type is set to the logical OR of all alarms, the alarm turns ON even if at least one of the alarms occurs. When the event type is set to PV range alarm, the alarm turns ON even if at least one of the alarms in the PV range alarm group occurs. When the event type is set to controller alarm, the alarm turns ON even if at least one of the alarms in the DCP32 alarm group occurs.

• ADV This is ON for one second after executing program advance. The event ON delay setting is also enabled.

● Time events

When the event 1 to 3 type is set to time event, the event can be used in the same way as time events 1 to 5. However, note that events 1 to 3 do not have segment No. event functions. Though the event standby function does not function, the ON delay function does.

Page 60

Chapter 5. FUNCTIONS

■ Time events 1 to 5

Either of time events or segment No. events can be selected by the time event type item in the event configuration data setup.

● Time events

The ON and OFF times or only the ON time can be set for each event No. and segment. The following describes ON/OFF of output.

• When the ON time is smaller than the OFF time, output is ON for the duration from the ON time to the OFF time. (See segments 1, 6 and 7 in the figure.)

• When only the ON time is set, output is ON for the duration from the ON time to the segment end point. (See segments 2 and 5 in the figure.)

• When neither the ON time nor OFF time are set, output is OFF. (See segment 3 in the figure.)

• Setting only the OFF time without an ON time is not possible. (See segment 3B in the figure.)

• Setting an ON time to be greater to or equal than the OFF time is not possible. (See segment 3C in the figure.)

• Only ON and OFF times set within the segment time are valid. Times straddling the next segment are invalid. The ON and OFF times set in the next segment are valid. (See segments 4 and 5 in the figure.) Accordingly, the ON and OFF times settings at the segment end point are ignored. However, ON and OFF times set for segment end points when the END mode is moved to are valid. (See segment 9 in the figure, and compare with segment 10 in the END mode.)

• When the ON time is set to 0 (no OFF time setting, or OFF time is greater than 0), output becomes OFF at time 0. If output at the previous segment end point was ON at this time, the output status at the segment switching point does not momentarily become OFF. (See segments 5 and 6 in the figure.)

• The G.Soak standby time is not included in the ON and OFF times. (See segment 7 in the figure.)

• If the ON time is set to 0 in the case of G.Soak standby, output becomes ON from the G.Soak standby state, and the ON time is started at completion of the G.Soak standby time. The output time = G.Soak standby time + OFF time (See segment 8 in the figure.)

• ON and OFF time settings the same time as the segment end point are valid in the case of the final segment END mode. (See segment 10 in the figure.)

● Segment No. events

The current segment No. is output as binary code. When all of T1 to T5 are selected as segment No. events in the time event type setup, all ON-OFF operations are as shown in the following table. When T1 to T4 are assigned partially to segment No. events, only the assigned time events operate as shown in the following table, and the remaining events operate as regular time events.

■ PID set selection

• Eight sets of PID parameters, PID1 to PID8 for CH1 and PID2-1 to PID 2-8 for CH2, are used for control operation. When the PID set No. is set to each segment by designating the PID set segment, control output is calculated by each of the PID parameters.

• There are two ways of selecting PID sets: by designating the PID set segment and by PID set auto-switching. The method can be selected by setting setup data

C11

set to 0: Designation of CH1 PID set

set to 1: CH1 PID set auto-switching

C34

These two methods cannot be set simultaneously in PID set selection on the same channel.

Note

When setup data C11 is set to 1, PID set No. items (CH1) in the program setup are not displayed. When setup data C34 is set to 1, PID set No. items (CH2) in the program setup are not displayed.

• By designation of PID set segment, the PID set No. is set for each segment, and control output is calculated by each of the PID parameters.

• By PID set auto-switching, the SP fullscale is divided into eight zones according to the settings of

CP.11

Chapter 5. FUNCTIONS

■ G.Soak (guarantee soak)

G.Soak ON/OFF and G.Soak width can be set for each segment. The G.Soak time can also be set by the variable parameter

gs.t

item. The G.Soak function ensures a segment execution time with PV close to SP. G.Soak functions not only in soak segments but also in ramp segments. At the segment start point, PV and SP are compared, and the absolute value of the resulting deviation continues for the G.Soak time or longer. When the absolute value is smaller than the G.Soak width, operation of that segment is started. The DCP32 is in the G.Soak standby state until this condition is satisfied, and the line lamp on the left side of the profile display blinks. The operation state is the same as HOLD at the segment start point (time is set to 0). If G.Soak standby is canceled on both channels when G.Soak is set to ON on channels CH1 and CH2, operation of that segment starts. However, note that in the FAST mode, the DCP32 does not enter the G.Soak standby state even if G.Soak is set to ON. The G.Soak standby state can also be canceled by external switch output. The following cancel conditions can be used for both CH1 and CH2, and selected by the setup date

settings.

Chapter 5. FUNCTIONS

■ PV start

If PV start is set in the program setup, PV is started by regular RUN operation. The first point where PV matches the SP in the program pattern (including bias for both PV and SP) is searched for, and operation is started from that point. However, note that if a matching point is not found, operation is started from the beginning of segment 1. You can select in the program setup which channel, CH1 or CH2, PV and SP is to be used. When PV has started, event operating points and the time of time events are automatically corrected. If the PV start function is selected by setup data

C52

C54

settings relating to external switch input, PV start can be executed without setting PV start in the program setup. PV start is valid on the segment of the currently selected program, and is invalid on the segment of the pattern link destination.

■ Cycle

The cycle function is for repeating operation from the No.1 segment of the program pattern to the final set segment for a preset number of cycles. The number of cycles can be set up to

9999. When a number of cycles “n” is set, the operation count becomes “n+1”. When executing cycle operation, operation at the end point of the final segment is not carried out, and operation is restarted with the effective value (setting of previous segment continued) of the program item (e.g. PV event value, PID set No.) whose setting is continuous from the previous segment cleared. At this time, PV is not started and operation starts from the No.1 segment even if PV start is set. If the SPs at the pattern start and end points do not match, the SP changes in a stepped manner during cycle operation. Cycle operation functions simultaneously on both patterns of SP1 and SP2.

■ Pattern link

“Pattern link” is a function for linking patterns together. The link destination program No. is set by the pattern link item. When the pattern link item is set to 0 (default), patterns are not linked. When the No. of the current program itself is set to the pattern link item, this creates an endless loop. If the SPs at the link source end point and the link destination start point do not match, the SP changes in a stepped manner during link operation. When cycle operation has been set, the pattern link function works after cycle operation has ended. After pattern link operation ends, operation begins from the No.1 segment of the link destination pattern, so operation is restarted with the effective value (setting of previous segment continued) of the program item (e.g. PV event value, PID set No.) whose setting is continuous from the previous segment cleared. If PV start is programmed to the link destination pattern, the PV start function operates after the link is made. After the link has been made, PID operation is not initialized, and is continued. Pattern link functions simultaneously on both patterns of SP1 and SP2.

■ Tag

A “tag” is eight alphanumeric data that can be set to each program. Though this item cannot be displayed nor set on the DCP32, it can be displayed and set on the smart loader package. When the pattern items of segment 1 has been set by program setup, a total of eight characters (“PROG” + program No. (2 characters) + “__” (two spaces)) are automatically set.

Example: In the case of program No.1: “

5 - 3 Modes

■ Mode types

The following modes are available on the DCP32.

● Program operation

The DCP32 operates according to SP, times, events, etc. set to program patterns No.1 to 19.

● Constant-value operation

The DCP32 operates according to SP or events set in the constant-value operation data. Time events 1 to 5 turn OFF.

● READY

In this mode, the DCP32 is ready for operation. MV output is fixed, and events to be operated according to event setting values turn OFF. However, events to be operated according to controller states are active. Parameters for all of the setup data, some event configuration data and some constant-value operation data can be set or changed only in the READY mode. During program operation, program pattern Nos.1 to 19 can be selected.

● RUN

In this mode, the program is running. MV outputs are active in PID control, and events and time events are active. In the program operation mode, program operation progresses according to the elapsed time. However, note that progress of program operation stops in the same way as the HOLD mode when the DCP32 is in the G.Soak (Guarantee Soak) standby state.

● HOLD

In this mode, program operation is held. Progress of program operation stops. However, note that MV outputs are active in PID control, and events and time events are active in the same way as in the RUN mode. The HOLD mode is not available during constant-value operation.

● FAST

In this mode, the program is fast-forwarded. This mode is like the RUN mode except that progress of the program operation time is speeded up. The time scale is selected by the variable parameter

FASt

setting. MV outputs are active in PID control or ON-OFF control, and events and time events are active. The DCP32 does not enter the G.Soak standby state even if G.Soak (Guarantee Soak) is set. The FAST mode is not available during constant-value operation.

● END

In this mode, operation of the program has ended. MV outputs are active in PID control or ON-OFF control, and events and time events are active with program operation stopped at the program end point. The END mode is not available during constant-value operation.

● AUTO

In this mode, program operation is automatic. MV output is active according to control by the DCP32. (However, note that when programmer functions are selected on the current output channels except heat/cool, SP output is active according to controller control by the DCP32.)

● MANUAL

In this mode, program operation is manual. MV output can be changed by ↑, ↓, ←, → on the console or by communications. (However, note that when programmer functions are selected on the current output channels except heat/cool, SP output can be changed by ↑, ↓, ←, → on the console or communications.)

■ Mode transition operations

The following describes mode transition operations. Though "program end" is not an operation, it is described below as it is a factor in mode transition.

● RUN

This operation involves moving to the RUN mode from the READY, HOLD or FAST modes. To move from the READY mode to the RUN mode, the DCP32 must be in the basic display state even in key, external switch input or communication operations.

● HOLD

This operation involves moving to the HOLD mode from the RUN or FAST modes. The HOLD mode is not available in the constant-value operation mode.

● RESET

This operation involves moving to the READY mode from the RUN, HOLD, FAST or END modes. In the program operation mode, this mode includes returning to the No.1 segment.

● ADV

This operation involves advancing one segment in the READY, RUN, HOLD or FAST modes. The ADV mode is not available in the constant-value operation mode.

● FAST

This operation involves moving to the FAST mode from the RUN or HOLD modes. The FAST mode is not available in the constant-value operation mode.

● AUTO

This operation involves moving to the AUTO mode from the MANUAL mode of the displayed channel.

● MANUAL

This operation involves moving to the MANUAL mode from the AUTO mode for the displayed channel. When the DCP32 enters the MANUAL mode, the basic display state changes as follows.

• When controller functions are selected, PV and output value (%) are displayed.

• When programmer functions are selected, PV and SP are displayed. When the DCP32 enters the MANUAL mode from the AUTO mode by external switch inputs or communications, the display changes to the basic display state even in the parameter setup or program setup states. However, note that when SPw programmer functions are selected, PVw and SPw are displayed on the CH2 display on a temperature/humidity operation model if variable parameter 2

CH.2

setting is 2. If the setting is other than 2, the basic

display does not change.

● Program end

When operation progresses in the RUN or FAST modes in the program operation mode, or when the segment has been advanced in the ADV mode, the program ends when all end points in the program setup including cycles and pattern links have been reached. You can select in the setup setting in which of the READY or END modes program operation ends. The program does not end in the constant-value operation mode.

5 - 4 Controller and Programmer

● Programmer

When the DCP32 is used as a programmer, PID control operation is not carried out, and the SP is output in the scaled 4 to 20 mA range. In the MANUAL mode, the SP can be incremented or decremented in the basic display state by the console keys. You can also select use of the DCP32 as a programmer on either just one of channels CH1 and CH2 or both channels.

DCP32 Channel 1 controller or Channel 2 controller

Controlled system 1

MV1

PV1

PV2

MV2

Controlled system 2

On the current output channels except heat/cool, you can choose between use of the DCP32 as a controller or a programmer. Set this in setup data

C18 orC41

. You can also choose between controller or programmer functions even if the DCP32 is used for program operation or constant-value operation. Channels on other output models are limited to use as a controller at all times.

● Controller

When the DCP32 is used as a controller, PID control operation is carried out according to PV, SP and PID setting values, and the resulting manipulated variable (MV) is output as an analog output. Heat/cool PID control and 3-position-proportional is also possible instead of PID control depending on the type of output supported by the DCP32 model. In the MANUAL mode, the MV can be incremented or decremented in the basic display state by the console keys.

5 - 6 Output Processing Functions

Three outputs are provided as output processing functions: control output, SP output and auxiliary output.

■ MV1/MV2 switching

MV1 and MV2 according to control output or SP output, and outputs 1, 2 and 3 can be switched as shown in the figures below. (Processing in these figures advances from left to right.)

● 0D, 5G output

● 2G output

● 3D, 5K output

Handling Precautions

• Switching of MV1 and MV2, and outputs 1, 2 and 3 can be selected in setup data

C44

• Switching of control output and SP output can be selected in setup data

C18

and

C41

• SP output can be output to current output other than heat output and cool output.

• The “MV1/MV2 switching” function can be used for SP output even though SP output originally is not MV. So, SP output is shown to be connectable to MV1 and MV2 in the above figures for convenience only.

The DCP32 is not equipped with a power switch or protective fuses. If necessary, prepare these externally. When a voltage of 90 to 264 Vac is applied across terminals 1 and 2 on the DCP32, the display appears for about ten seconds after which control and other operations are started. During initialization of the controller until start of operations, the LEDs on the profile display light successively at uneven intervals clockwise from top right. The following diagram shows the flow of operations at startup.

Chapter 6. OPERATION

The “basic display state” of the DCP32 collectively refers to the display state of the program No. display, segment No. display, upper display, lower display, basic indicator LED lamps and event LEDs. Each press of the DISP key successively switches the basic display state, and each press of the DISP key with the FUNC key held down switches the channel displays between CH1 and CH2. Operation of other displays and LEDs is carried out in the same way even when setting up parameters, for example. However, switching by the DISP key is not possible. The profile display and AT LED indicates the status of the channel displayed in the basic display.

The following figure shows the conventions used for representing displays in this manual.

Chapter 6. OPERATION

■ Read timing

● Timing of inputs RSW1 to 7

Inputs RSW1 to RSW7 are read according to the following timing. 1 When input state changes from OFF to ON, the time from the change up to

reading is 0.2 seconds max.

2 When input state changes from ON to OFF, the time from the change up to

reading is 0.2 seconds max.

● Timing of inputs RSW8 to 12, RUN and PV start

The time from the change in input state up to reading when selecting program Nos. by RSW8 to RSW12 is 0.4 seconds max. Accordingly, due to the relationship with RUN operation, be sure to observe timings 1 to 4 in the following diagram. PV start operation also must conform to RUN operation. 1 The time from fixing of the selected No. up to the rising edge of the RUN

signal is 0.4 seconds min.

2 The time from the rising edge of the RUN signal up to holding of the program

No. is 0.2 seconds min.

3 The time from holding of RUN signal OFF up to the rising edge of the RUN

signal is 0.2 seconds min.

4 The time from the rising edge of the RUN signal up to holding of RUN signal

ON is 0.2 seconds min.

5 The time from fixing of the selected No. up to changing of the program No. is

0.4 seconds max.

6 The time from the rising edge of the RUN signal up to start of RUN is 0.4

seconds max.

Handling Precautions

When operating the DCP32 by external switch inputs, operation can be carried out more reliably if a margin is added to the minimum time for the above read timings.

6 - 5 Manual Operation and Auto-tuning

Chapter 6. OPERATION

■ Manual operation

In the MANUAL mode, controller outputs can be manipulated by ↑ or ↓ on the console.

● Controller functions

When outputs are displayed in the basic display state, only one digit in the output value blinks. If the output value is incremented or decremented by ↑ or ↓, actual output also increments or decrements. Output values differ from values being entered to setting items in that the ENT key need not be pressed. The blinking digit can be moved by pressing ← or →. On 2G output models, when only estimated position-proportional control is selected by variable parameter

m-C

setting 2, “----” not the value is displayed as

the output display in the MANUAL mode. Pressing ↑ displays “

oPEn

” , and the open-side relay turns ON.

Pressing ↓ displays “

CLoS

”, and the closed-side relay turns ON.

Bump-less and preset output changes when moving from the AUTO to the MANUAL mode can be selected by setup data

C14

(for MV1) or

C37

(for MV2) setting. When moving from the MANUAL to the AUTO mode, the change in output is bumpless. (However, note that a sudden change in output occurs when the total time for the PID parameter of the PID set in use is set to “0”.)

● Programmer functions

On the current output channel, when programmer functions are in operation with setup data

C18

(for CH1) or

C41

(for CH2) set to 1, SP can be manually manipulated. When SP is displayed in the basic display state, only one digit in the SP value being entered blinks. When the SP value is incremented or decremented by ↑ or ↓, the actual SP output also increments or decrements. SP values differ from values being entered to setting items in that the ENT key need not be pressed. The blinking digit can be moved by pressing ← or →. Output changes when moving from the AUTO to the MANUAL mode are bumpless regardless of setup data

C14

(for CH1) or

C37

(for CH2) setting. When moving from the MANUAL to the AUTO mode, the SP becomes the program pattern SP, which results in a sudden change in output.

■ Auto-tuning (AT)

When operating in the AUTO mode in either of the RUN, HOLD, FAST or END modes, setting values can be automatically written to the PID set in use by autotuning (AT). The following can be selected by variable parameter At(for CH1) or

At.2

(for CH2) setting.

0:AT is disabled.

1: General AT is executed. 2: Overshoot-inhibited AT is executed. 3: AT by neutral net is executed.

• Auto-tuning does not function when programmer functions are selected on

heat/cool output channel models and current output channel models.

6-14

Page 99

6-15

Chapter 6. OPERATION

• During execution of auto-tuning, progress of program operation time stops. Accordingly, the DCP32 is in a similar state to the HOLD mode even in the RUN or FAST modes.

• Auto-tuning in all instances involves calculating the downtime and critical sensitivity of the control system according to two limit cycles and PID values according to suitable characteristic equations for each, and automatically writing these PID values.

• During execution of auto-tuning, PV fluctuates according to fluctuations in MV. Before executing auto-tuning, make sure that fluctuations in PV will not cause controller trouble.

• Normally, suitable values are written by setting variable parameter At setting to 1 or 3. However, when executing auto-tuning on a control system that easily overshoots, either set to 2, or also use smart-tuning for carrying out overshoot inhibit control. Setting to 3 executes AT by neural net so that suitable values are calculated for wider range applications.

• The point at which output at auto-tuning is inverted (lower limit to upper limit, and vice versa) is determined as follows from SP and PV at start of auto-tuning.

• Auto-tuning can be started by the AT key, external switch inputs and communications. The AT key functions on the currently displayed channel. During auto-tuning, the AT LED on the currently displayed channel blinks.

• If one or more of the following conditions occurs during auto-tuning, autotuning is canceled without PID constants being written, and the AT LED goes out.

- Cancellation by the AT key (when the displayed channel indicates auto-tuning

in progress)

- Cancellation by external switch input

- Cancellation by communications

- Change in mode (move to MANUAL mode or READY mode)

- Execution of automatic motor valve opening adjustment on 2G output models

- When variable parameter At(for CH1) setting is changed to “0”

- When variable parameter 2

At.2

(for CH2) setting is changed to “0”

- When PV becomes out-of-range

Handling Precautions

• Auto-tuning will not function properly unless the control target is connected.

• The time from start to end of auto-tuning varies according to the control target.

Page 100

6-16

Chapter 6. OPERATION

• When auto-tuning is executed, control is stopped, and ON/OFF output switching (if the output type is relay output or voltage output) or output switching between the manipulated variable upper and lower limits of the currently selected PID set (if the output type is current output or positionproportional output) is repeated several times. If this causes controller trouble, manually set the PID value.

• Sometimes a suitable PID value cannot be obtained depending on the control target. If this happens, manually set the PID value.

• Though auto-tuning can be executed simultaneously on both the CH1 and CH2 channels, suitable PID values cannot be obtained if PVs in each channel interfere with each. If this happens, execute auto-tuning on each channel individually.
