1. OUTLINE

1.1 Features

This high performance digital controller has the following features:



Panel space saving: 60 mm depth (RZ400 and RS400), 63 mm (RZ100 and RS100)

 Sampling cycle 0.25 seconds
 Incorporates Autotuning (AT) for easy setting of PID values

Automatically calculates the PID values to provide fast stabilization.

 “Fine tuning” that changes responsiveness

A new 6 level Fine tuning allows the operator to control response from fast to slow by changing th e Fine tuning setting
(3 to 3) while the PID constant remains unchanged.

 Startup tuning eliminates autotuning time

Conventional autotuning time is eliminated by startup tuning which calcu lates optimum PID values immediately upon
startup.

 Freely assignable outputs

This instrument can incorporate up to three outputs. Each output port can be freely configured for control outputs
(heating and cooling outputs) and alarm outputs (including heater break alarm outputs).

 Easy parameter setup via USB loader port (only RZ100/400)

A user can easily save parameter settings to a PC and copy parameters to other controllers with the USB port, a
COM-K2 converter, and dedicated PROTEM2 software for the RZ100/400.

(Loader communication is available only while RZ100/400 are powered.)

Download the software from the official RKC website:
http://www.rkcinst.com

 IP66 waterproof and dustproof protection for severe environments (option of RZ100/400)

Waterproof and dustproof construction (IP66) applies to the front part of the instrument when properly installed on the
panel.

3. WIRING

3.1 Wiring Cautions

To prevent electric shock or instrument failure, do not turn on the power until all wiring
is completed. Make sure that the wiring is correct before applying power to the
instrument.

 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.

 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.

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

of the noise filter.

 Allow approximately 5 seconds for contact output after the instrument is turned on. Use a delay relay when

the output line is used for an external interlock circuit.

 Power supply wiring must be twisted and have a low voltage drop.
 This instrument is not provided with an overcurrent protection device (fuse). If a fuse is required for safety,

install a fuse close to the instrument.
Fuse type: Time-lag fuse
Fuse rating: Rated voltage 250 V, Rated current 1 A

 Use the solderless terminal appropriate to the screw size.

3. WIRING

 When wiring RZ100/RZ400/RS100/RS400, wire from the left direction toward the backside terminals as

shown in Fig. 3.2.
For RZ100/RS100, the wiring surfaces of the central and the right side lines of terminals are inclined to
make it easier to wire from the left side.
When using the terminal cover (Figs. 3.2, 3.5), it is not possible to wire from the right side.
When wiring from the left and right with a close mounting, there are cases where adjacent instruments
cannot be wired.

 Up to two solderless terminal lugs can be connected to one terminal screw.

However, reinforced insulation cannot be assured in this case.

(RZ100/RS100 is used in the example shown, but restrictions for crossover wiring are the same for RZ400/RS400.)

Panel

Top view

If solderless terminal lugs other than the recommended dimensions are used, terminal screws may
not tighten. In that case, bend each solderless terminal lug before wiring.
If the terminal screw is forcibly tightened, it may be damaged.

In case of RZ100/RS100, if two solderless terminal lugs are connected to one terminal screw, a
terminal cover cannot be used.

 Caution for using the terminal cover:

 To prevent electric shock or instrument failure, always turn off the power before mounting or removing

the terminal cover.

 When mounting and removing the terminal cover, apply pressure very carefully to avoid damage to the

terminal cover.

 If a solderless terminal lug touches the RZ400/RS400 common terminal cover, remove the projection

from the terminal cover by manually bending it back and forth until it breaks off.

4.4 Protecting Setting Data

To protect setting data in the instrument, the setting data can be locked so that no changes can be made (Set
data lock function). The Set data lock function uses the lower three digits of the set value to restrict the
setting in the SV setting mode, the Parameter setting mode, and the Communication setting mode.
The highest digit is used to show/hide the Initial setting mode.

Perform setting in the Parameter setting mode.

IMR02Y03-E1

 Set data lock (Parameter setting mode)
The contents of lock mode can be switched anytime regardless of RUN/STOP mode.

As the parameters can be viewed even in the lock state, the set data can be verified.
However, when the set value (SV) is locked, the SV screen in the SV setting mode will not be
displayed. (Refer to P.8-8)

Setting through the Communication (optional) is possible even when setting is locked. However, to
change parameters in the Initial setting mode, the controller must be set to STOP mode.

5. OPERATION

5.1 Operating Precautions

Before starting the operation, check the following items.

 Power ON

As soon as the instrument is powered up, operation is started after the display of the input type and the input
range.

 Action at input error

In case of input failure this instrument provides the following behaviors and output.

 Action at input break

Thermocouple input: Upscale
RTD input: Upscale

 Action at input short-circuit

RTD input: Downscale

 Action at input burnout

Control output at burnout (Initial setting mode) [refer to P. 6-11]:

 Result of cont rol com putati on
 PID control: Output limiter low (output OFF)

Heat/Cool PID control: 5.0 % (output OFF) *

* On the Heat/Cool PID control type, both heating and cooling outputs are off.

Alarm action at input burnout (Initial setting mode) [refer to P. 6-11]:

 Alarm output is not forcibly turned ON when the burnout function is activated.
 ON at over-scale; no action at underscale
 ON at underscale; no action at over-scale
 ON at over-scale or underscale
 OFF at over-scale or underscale

 Checking each parameter

 The settings for the Set value (SV) and all parameters should be appropriate for the controlled system.
 With the factory setting, all parameters cannot be verified. Switch the mode to “Expanded display mode,”

then the parameters not displayed can be seen. Some parameters may not be displayed if display
requirements are not met.

 With the factory setting, control is stopped if the mode is switched to the Initial setting mode. It is possible

to verify the parameters in the Initial setting mode without stopping the control. However, to change the
parameters in the Initial setting mode, the control needs to be stopped, because the parameters in the Initial
setting mode cannot be changed while the control is running.

Refer to 4. BASIC OPERATION AND PARAMETER LIST (P. 4-1) and chapters 6 to 11 for
switching between each mode and details of parameters.

For switching to the Expanded display mode, refer to 9.1 Releasing the Display Restriction of the
Parameters (P. 9-2).

For continuing the control in the Initial setting mode, refer to 8.2 Continuing the Control when
Entering the Initial Setting Mode (P. 8-5).

5-2 IMR02Y03-E1

5. OPERATION

 Alarm hold action

 The Alarm hold action is activated when the power is turned on or when transferred from STOP mode to

RUN mode. (in case of “with hold action”)

 The Alarm re-hold action is activated when not only the Set value (SV) is changed, but also the power is

turned on or when transferred from STOP mode to RUN mode. (in case of “with re-hold action”)

 Operation at power failure

A power failure of 20 ms or less will not affect the control action (at 100 V AC). When a power failure of
more than 20 ms occurs the instrument assumes that the power has been turned off. The instrument restarts
from the mode operated prior to the power failure.

For operation in initial setting (Initial setting mode),
refer to 5.3 Initial Setup before Operation (P. 5-5).

For operation setting, refer to the following:

 5.4 Setting the Control Set Value [Set value (SV)]

(P. 5-12)

 5.5 Setting the Alarm Set Value (P. 5-13)

For starting the operation, refer to 5.6 Tuning the PID
Parameters (Execution of AT) (P. 5-14).

5. OPERATION

5.3 Initial Setup before Operation

Before starting the operation, confirm that the set value of the parameter matches the model code as specified
when ordered. Parameters which were not specified when ordered must be set before use.
Some functions may need to be set in the Initial setting mode. Read the following part before attempting the
setting.

Parameters in the Initial setting mode should be set according to the application
before setting any parameters related to operation. Once the parameters in the Initial
setting mode are set correctly, no further changes need to be made to the parameters
for the same application under normal conditions. If they are changed unnecessarily, it
may result in malfunction or failure of the instrument. RKC will not bear any
responsibility for malfunction or failure as a result of improper changes in the Initial
setting mode.

To make setting in the Initial setting mode, control needs to be stopped (STOP). With the
factory setting, control is stopped when the mode is switched to the Initial setting mode.
When the mode is switched back to the Monitor display mode from the Initial setting mode,
control is started (RUN) again.

Control can be set to continue after switching to the Initial setting mode. For details, refer to

8.2 Continuing the Control when Entering the Initial Setting Mode (P. 8-5). Even if the control
is set to continue in the Initial setting mode, the Initial setting mode still requires the control to be
stopped (STOP). Switching between RUN and STOP can be made only in the Monitor display
mode.

Set value change and registration

 The highlighted digit indicates which digit can be set. The highlighted digit can be shifted by

pressing the key.

 However, the changed data is not stored by the operation of the and keys alone. In order

to store the new parameter value, the key must be pressed. within 1 minute after the new value
is displayed. The new value will then be saved and the display will move to the next parameter.

 In any mode other than the Initial setting mode, if no registration is made within 1 minute after the

change, the display returns to the PV/SV monitor. In such a case the changed data is not stored.

 In the Initial setting mode, if no registration operation is made within 1 minute after the change, the

display returns to the Initial setting code number screen to which the displayed parameter belongs
(For example, in case of the Control output assignment screen, the display returns to the initial
setting code 0002 screen). The changed data will not be stored in this case either.

6.2 Correcting Input

PV bias can be used for Input correction. The PV bias is used to compensate the individual variations of the
sensors or correct the difference between the Measured value (PV) of other instruments.

 Description of function
 PV bias

PV bias adds bias to the Measured value (PV).

Setting example of PV bias:
When measuring the same type of load by using different sensors, the Measured value (PV) will be

displayed differently based on the features of sensors:

RZ400 [A]: 200 C RZ400 [B]: 198 C

To correct the Measure value (PV) of RZ400 [B], add bias of 2 C by PV bias:

Displayed value = Measured value (PV) + PV bias  198 C  2 C  200 C

6.3 Removing Input Noise

To remove input noise influence, first-order delay PV digital filter is available.

 Description of function

PV digital filter is software designed to reduce variance of PV caused by noise. Effect of Input noise can be
reduced by setting time constant of PV digital filter based on the controlled object requirement and its level
of noise. Setting a value too small leads to a poor result of PV digital filter; just as an input response will be
poor when setting a value too large.
