3. WIRING

3.1 Wiring Cautions

• For thermocouple input, use the appropriate compensation wire.

• For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires.

• To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric equipment.

• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

- Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise reduction.

Instrument power

Twist these leadwires

IN OUT

- Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise filter output and the instrument power supply terminals to achieve the most effective noise reduction.

Shorten distance between pitches

Noise filter

Minimize distance

Instrument power terminals

- Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter.

• Power supply wiring must be twisted and have a low voltage drop.

• About four seconds are required as preparation time for contact output every time the instrument is turned on. Use a delay relay when the output line, is used for an external interlock circuit.

• This instrument is not furnished with a power supply switch or fuses. Therefore, if a fuse or power supply switch is required, install close to the instrument.

- Fuse type: Time-lag fuse

- Recommended fuse rating: Rated voltage 250 V Rated current: 1 A

• For the current input specification, a resistor of 250 Ω (±0.02 % ±10 ppm, 0.25 W or more) must be connected between the input terminals. This resistor must be provided by the customer.

• Use the solderless terminal appropriate to the screw size.

- Screw size: M3 x 6

- Recommended tightening torque: 0.4 N m [4 kgf cm]

• For an instrument with 24 V power supply, supply power from a SELV circuit.

Heater Break Alarm (HBA) function

The HBA function monitors the current flowing through the load by a dedicated current transformer (CT), compares the measured value with the HBA set value, and detects a fault in the heating circuit.

Low or No current flow (Heater break, malfunction of the control device, etc.):

When the control output is ON and the current transformer input value is equal to or less than the heater break determination point for the preset number of consecutive sampling cycle, an alarm is activated.

Over current or short-circuit:

When the control output is OFF and the current transformer input value is equal to or greater than the heater break determination point for the preset number of consecutive sampling cycle, an alarm is activated.

Precaution for HBA setting:

• Displayed only for when HBA is selected as Alarm 2.

• HBA is not available on a current output.

• Set the set value to approximately 85 % of the maximum reading of the CT input.

• Set the set value to a slightly smaller value to prevent a false alarm if the power supply may become unstable.

• When more than one heater is connected in parallel, it may be necessary to increase the HBA set value to detect a single heater failure.

• When the current transformer is not connected, the HBA is turned on.

2

Control Loop Break Alarm (LBA) function

The LBA function is used to detect a load (heater) break or a failure in the external actuator (power controller, magnet relay, etc.), or a failure in the control loop caused by an input (sensor) break. The LBA function is activated when control output reaches

0 % (low limit with output limit function) or 100 % (high limit with output limit function). LBA monitors variation of the measured value (PV) for the length of LBA time. When the LBA time has elapsed and the PV is still within the alarm determination range, the LBA will be ON.

Precaution for LBA setting:

• Displayed only for when LBA is selected as Alarm 1 or Alarm 2.

• No control loop break alarm can be used at heat/cool PID control action.

• The LBA function can not be activated when AT function is turned on.

• The LBA function is activated when control output reaches 0 % or 100 %. The time required for the LBA output to turn on includes both the time from the initial occurrence of loop failure and the LBA setting time. Recommended setting for LBA is for the set value of the LBA to be twice the value of the integral time (I).

• If LBA setting time does not match the controlled object requirements, the LBA selling time should be lengthened.

If setting time is not correct, the LBA will malfunction by turning on or off at inappropriate times or not turning on at all.

3

LBA Deadband function

The LBA may malfunction due to external disturbances. To prevent malfunctioning due to external disturbance, LBA deadband (LBD) sets a neutral zone in which LBA is not activated.

When the measured value (PV) is within the LBD area, LBA will not be activated. If the LBD setting is not correct, the LBA will not work correctly.

6. OPERATIONS

6.1 Operation Procedures

CAUTIONS

All mounting and wiring must be completed before the power is turned on. If the input signal wiring is disconnected or short-circuited (RTD input only), the instrument determines that burnout has occurred.

− Displays:

• Upscale:

• Downscale

Thermocouple input, RTD input (when input break)

Thermocouple input (specify when ordering), RTD input (when short-circuited), Voltage input (1 to 5 V DC),

Current input (4 to 20 mA DC)

• For the voltage (0 to 5 V DC, 0 to 10 V DC*) or current (0 to 20 mA DC) input, the display becomes indefinite (display of about zero value).

* Z-1010 specification

− Outputs:

• Control output: OFF (Heat/Cool control: the control output on both heat-side and cool-side is turned off)

• Alarm output: Both of the Alarm 1 and Alarm 2 outputs of this instrument are turned on when burnout occurs regardless of any of the following actions taken (High alarm, low alarm, etc.). In addition, when used for any purposes other than these alarms (event, etc.), specify the Z-124 specification (not to be forcibly turned on).

A power failure of 20 ms or less will not affect the control action. When a power failure of more than 20 ms occurs, the instrument assumes that the power has been turned off. When power returns, the controller will retain the conditions that existed prior to shut down.

The alarm hold action is activated when not only the power is turned on, but also the SV is changed.

1. Prior to starting operation, check that the mounting and wiring have been finished, and that the SV and various parameters have been set.

2. A power supply switch is not furnished with this instrument. It is ready to operate as soon as the power is turned on.

(Factory set value: RUN).

This instrument holds the conditions that exist just before the power is turned on. For example, if the power is turned off in STOP mode, the instrument starts in STOP mode when the power is turned on again.

RUN/STOP

Each time the <R/S key is pressed for 1 second, RUN/STOP mode changes from RUN to STOP or STOP to RUN. If the instrument is switched to STOP mode, its display, output, etc. become as follows.

• Display:

• Output:

The PV display shows (STOP).

Control output OFF, Alarm output OFF

• Autotuning: AT canceled (The PID constants are not updated.)

RUN/STOP display (Z-1018 specification)

When operation is changed to the STOP mode by RUN/STOP selection, a parameter symbol to indicate the STOP mode is displayed on the SV display. Pressing the SET key with the STOP mode displayed can also check and change the set value (SV).

6.2 Set Data Lock (LCK) Function

The set data lock restricts parameter setting changes by key operation. This function prevents the operator from making errors during operation. There are 8 set data lock levels. (see below)

Set value Parameters which can be changed

0000 All parameters [Factory set value]

0001 SV, Alarms (ALM1, ALM2)

0010 All parameters except for Alarms (ALM1, ALM2)

0011 SV

0100 All parameters except for SV

(ALM1,

0110 All parameters except for SV and Alarms (ALM1, ALM2)

0111 No parameters (All Locked)

HBA, LBA and LBD can be locked when any of 0001, 0011, 0101 and

0111 is set.

Set Data Lock can be changed in both RUN and STOP mode.

Parameters protected by Set Data Lock function are still displayed for monitoring.

6.3 Autotuning (AT) Function

Autotuning (AT) automatically measures, calculates and sets the optimum PID and LBA constants. The following conditions are necessary to carry out autotuning and the conditions which will cause the autotuning to stop.

Caution for using the Autotuning (AT)

When a temperature change (UP and/or Down) is 1

°C or

less per minute during Autotuning, Autotuning may be cancelled before calculating PID values. In that case, adjust the PID values manually. It is possible to happen when the set value is around the ambient temperature or is close to the maximum temperature achieved by the load.

Requirements for AT start

Start the autotuning when all following conditions are satisfied:

• Prior to starting the AT function, end all the parameter settings other than PID and LBA.

• Confirm the LCK function has not been engaged.

When the autotuning is finished, the controller will automatically returns to PID control.

Requirements for AT cancellation

The autotuning is canceled if any of the following conditions exist.

• When the set value (SV) is changed.

• When the PV bias value is changed.

• When the RUN/STOP mode is changed to the STOP mode.

• When the PV becomes abnormal due to burnout.

• When the power is turned off.

• When power failure longer than 20 ms occurs.

• When the AT does not end in 9 hours after autotuning started.

If the AT is canceled, the controller immediately changes to

PID control. The PID values will be the same as before AT was activated.

When AT is completed, the controller immediately changes to PID control. If the control system does not allow the AT cycling process, set each PID constant manually to meet the needs of the application.

6.4 Self-tuning (ST) Function

The ST function is used to automatically calculate and set adaptive PID constants anytime the power is turned on, the SV is changed or the controller detects unstable control conditions.

The ST function should be turned off when the controlled system is affected by rippling that occurs due to periodic external disturbances.

The power to the controlled system must be turned on before the power to the instrument is turned on or SV is changed. This is required when ST function is on.

To activate the ST function, the following parameters must not be set to zero: P

≠0, I≠0, D≠0, ARW≠0.

When heat/cool PID action is selected, the ST function can not be activated.

When the AT function is activated, the ST function can not be turned on.

When the ST function is activated, the PID and ARW settings can be monitored, but not changed.

7.7 SV Alarm Type Selection (SL11)

For ALM1 setting, the first digit from the right is set to “0” in the following cases.

• When the instrument does not have ALM1 output.

• When the ALM1 output is used for process/deviation/

band alarm or Loop Break Alarm (LBA).

For ALM2 setting, the third digit from the right is set to “0” in the following cases.

• When the instrument does not have ALM2 output.

• When the ALM1 output is used for process/deviation/

band alarm, Heater Break Alarm (HBA) or Loop Break

Alarm (LBA).

• When Z-168 is specified.

To make SV alarm setting effective, set SL4 to “0000” when using ALM1 for SV alarm, or set SL5 to “0000” when using ALM2 for SV alarm. SL4 and SL5 have priority to

SL11 setting.

Factory set value varies depending on the instrument specification.
