3-4. Wiring
In the wiring operation, close attention should be paid to the following:
In the wiring operation, follow the terminal layout shown in Section 3-5 and the terminal arrangement in Section 3-6 and make
sure to carry out the correct wiring process.
Use a press-fit terminal which fits an M3.5 screw and has a width of 7 mm or less.
In the case of thermocouple input, use a compensating conductor compatible with the selected type of thermocouple.
In the case of R.T.D. input, the resistance of a single lead wire must be 5Ωor less and the three wires must have the same
resistance.
The input signal wire must not be accommodated with a high-voltage power cable in the same conduit or duct.
Shield wiring (single point grounding) is effective against static induction noise.
Twisting the input wires at short and equal intervals is effective against electromagnetic induction noise.
In wiring for power supply, use a wire or cable whose performance is equal to or higher than the 600V vinyl insulated wire
having a sectional area of 1 mm2or larger.
The wire for grounding must have a sectional area of 2 mm2or larger and must be grounded at a grounding resistance of 100Ω
or less.
Clamp the screws of terminals firmly.
Clamping torque: 1.0 N •m (10 kgf •cm)
If the instrument appears to be easily affected by power supply noise, use a noise filter to prevent malfunctioning. Mount the
noise filter on the grounded panel and make the wire connection between the noise filter output and the power line terminals of
the controller as short as possible.
Connection of current detector (CT)
Insert a load line through the hole of the noise filter
meant for the controller. With this wire, connect the
secondary side terminal of CT to the CT input terminal
of the SR90 series controller.

5-4. Before Starting Up
To begin with, check the wiring and set the items listed below by the setting methods of the screen groups. (Factory-set items and
items already set by equipment manufacturers need not be set here.)
(1) Checking of wiring: Check that the wiring to connected terminals is carried out properly. Erroneous wiring will result in
burnout.
(2) Application of operating power: Apply operating power. The controller is energized and the data display and other lamps light.
(3) Setting of measuring range: Call the 1-48 measuring range code screen of the screen group 1 and select a code from the
measuring range codes. For current, voltage or mV input, lower/higher limit values and the position of decimal point should be
set. (Depending on a selected code, selection on the 1-49, 1-50 or 1-51 screen will be required.)
(4) Setting of control: In the case of ON-OFF (two-position) action, call the 1-2 output 1 proportional band setting screen of the
mode 1 screen group and select OFF and register it. Follow the same procedure for output 2 if the option is added. Omit this
setting in the case of AT.
(5) Setting of control output characteristics: Call the 1-42 control output characteristic setting screen of the screen group 1 and
select either RA or DA correspondingly to output characteristic specification as shown in the table.
(6) Setting of event type: If the optional event function is added, call the 1-20 event alarm type code setting screen of the screen
group 1 and select and register a code.
(7) Setting of analog output: If the optional analog output function is added, call the 1-31 analog output type setting screen of the
screen group 1 and select one from the setting range and register it.
(8) Note on initialization following data change: When the code of measuring range, type of event or type of analog output is
changed, a set value is initialized and resetting is required.
5-5. Procedure of Setting in Screen Group 0
In the follwing section 5-6, the flow of setting screens is explained in the next section, "Explanation of Screen Group 0 and Setting."
In this section, the procedure of setting is described.

Key operation: Use the key to call the next screen. On each setting screen, use the or key for selection and
the key for registration. Nevertheless, in case the value of manual control output is changed on the output
monitor screen, the key need not be pressed.
(1) Setting of target set value (SV)
To set a target set value (SV), press the or key on the 0-0 basic screen. When either of the keys is pressed
continuously, the decimal point of the rightmost digit flashes and the numerical value keeps increasing or decreasing.
When it reaches a target set value, press the key to register.
Once it reaches the target set value, the digit stops flashing. (Setting of a target set value is not possible while auto tuning (AT)
is in execution. AT should be relieved for setting.)

(2) Manual setting of control output
1) Switching between automatic output and manual output on output monitor screen (OUT1 and OUT2) and setting:
To switch auto to manual and vice versa, press the key for 3 seconds continuously on the output 1 or output 2 screen.
Upon turning to manual, the MAN lamp flashes and it remains unlighted during automatic output.
To set a target value, press the or key on the output monitor screen to keep the numerical value increasing or
decreasing until a target value is reached.
To release manual output, press the key again for 3 seconds continuously, and automatic output returns.
If the output mode of either output 1 or output 2 is changed to manual, the output mode of the other is also changed to
manual. Also, if changed to auto, the output of the other will be changed to auto as well.
In case the output of output 1 is at 100.0%, is displayed on the output 1 screen and the decimal point of flashes.
In case the output of output 2 is at 100.0%, is displayed on the output 2 screen and the decimal point of flashes.
In case output is of contact or SSR drive voltage and OFF is set for proportional band (P), the value of output will be 0.0%
or 100.0%.
In case output is of voltage or current and OFF is set for proportional band (P), the value of output will be the lower limit
value or the higher limit value of a set limiter.
While auto tuning (AT) is in execution, switching to manual output is not possible. It should be done after releasing AT.

2) Supplemtary explanation of using the manual adjustment output
Monitor screens (OUT1 and OUT2) and automatic/manual output:
When automatic output is changed to manual, output is put in a balanceless/bumpless action and the value of output
right before the change is displayed. Changing from manual to auto also causes bumpless action but not if the PV value
is outside the proportional band.
If power supply is shut off and power is applied again, control output continues to be in auto or manual at the time when
power supply is shut off.
Note: Although a change to another screen in the manual mode is possible, it should be noted that control output is
manual in this case. Flashing of the MAN monitor LED indicates that the manual mode is ON.
(3) AT (auto tuning)
AT is the function of automatically processing and setting P.I.D., the parameters of P.I.D. control. Processing time differs
depending on the details of control.

1) Execution of AT
Pressing the or key on the 0-3 AT action control screen changes displayed on the bottom to and the
decimal point of the rightmost digit flashes. Then press the key. The AT lamp flashes and AT starts. When AT is
executed, ON/OFF action of output in response to rising and falling of the measured value from the target set value is repeated
several times to store PID values internally and AT ends. At the same time control using stored PID values begins and the AT
lamp goes out.

2) Halfway releasing of AT
To stop AT in the middle of execution, select by using the or key on the AT action control screen and by
pressing the key, releases the AT and the decimal point and the AT lamp stops flashing.
Note: In case AT is released in the middle, PID values are not changed.
3) In the following conditions, AT is unable to be executed:
Control output is in manual. (The AT screen not displayed.)
Scaleover of PV (measured value). (The AT screen not displayed.)
OFF is selected for proportional band (P) of output 1. (The AT screen not displayed.)
Lock No. 2 or 3 selected on the keylock screen.
4) If the following occur while AT is in execution, AT will be released:
The output value has been at 0% or 100% continuously for 200 minutes.
Scaleover of PV value
5) AT works as follows in the instrument of two-output specifications:
RA characteristic: PID constants are common to OUT1 and OUT2.
DA characteristic: AT is executed only for OUT1 and while AT is in execution, output of OUT2 is at 0% or the lower
limiter value of output limiter.
(4) Setting of event set value
Before a value is set, an event type should be set as described in the following paragraph, 1) Event type setting. When an
event type code is changed, however, all the set values (data) concerning the event are initialized.
1) Event type (alarm type) setting
Call the 1-20 event 1 type code setting screen of the screen group 1 and select one from the type codes Hd, Ld, od, id, HA
and LA by pressing the and keys. Then register it by the key.
There are the following 6 event type (alarm type) codes: : Higher limit deviation, : Lower limit deviation,
: Outside higher/lower limit deviations, : Within higher/lower limit deviations, : Higher limit absolute value,
: Lower limit absolute value. A selected code is displayed and an action point is to be set for the selected event type
(alarm type). ( : None, : Scaleover, and : Heater break/loop alarm are screen display only.)
2) Setting of event value
The 0-4 event 1 set value setting screen or the 0-5 event 2 set value setting screen will set. It will be on display when
either of the previous 6 types of event is selected.
Set the aimed value by pressing the or key on screen. When the key is pressed to register the set event value,
the decimal point stops flashing.
Setting ranges: Higher limit deviation value or lower limit value: −1999 ~ 2000 units
Outside or within higher/lower limit deviation values: 0 ~ 2000 units
Higher limit absolute value or lower limit absolute value: Within measuring range
(No event value can be set while AT (auto tuning) is in execution. Set after releasing AT.)

3) Changing the event value
To change the value, pressing the or the key causes the decimal point to flash and the value will change. Press the
key to set your aimed value, the decimal points will stop flashing.
(5) Set value bias
1) Set value bias
As an optional function, additional setting of another target set value is possible.
It is set as a set value bias which indicates a deviation from the target set value.
For instance, when 20˚C has been set as the target set and you want to set another set value at 30˚C, set the set value bias at
+10˚C.
The set value bias becomes effective when the SB terminals are closed.
When the SB terminals are open, the target set value becomes effective.
This function is used conveniently to switch a target value between "summer and winter"/"day and night" and the like.
2) Setting of set value bias
In case the optional set value bias function is added, press the or key on the 0-6 screen to set a numerical value of
set value bias and register the value by pressing the key. The decimal point stops flashing.
The set value remains effective while the SB terminals are shorted and is added to the target set value. When a set value bias
is set, the SB/COM lamp lights.
Setting range: −1999~5000 units

6-1. Events
1) Deviation Alarm
An alarm action point is set by a deviation from target set value (SV). For example, when the target set value is 20˚C, +10˚C
should be set for higher limit deviation alarm in order to put an alarm in action at 30˚C and higher. To put an alarm in action at
30˚C and lower when the target set value is 100˚C, −70˚C should be set for higher limit deviation alarm. Higher limit deviation
alarm must be higher than the target set value and lower limit deviation alarm must be lower than the target set value. This is
conveniently used to make the alarm action point follow deviation from the target set value. The set range will be −1999~2000
unit.
2) Absolute Value Alarm
An alarm action point is set by an absolute value. For example, when the target set value is 20˚C, 30˚C should be set for higher
limit absolute alarm in order to put an alarm in action at 30˚C and higher. To put an alarm in action at 30˚C and lower when the
target set value is 100˚C, 30˚C should be set for lower limit absolute alarm. Both higher limit and lower limit can be set at any
value within the measuring range.
This alarm is convenient when the alarm action point is fixed.
3) Standby Action
This is used to withhold alarm action even when an alarm action point is reached when power is applied and to put the alarm in
action on the alarm action point after a target set value (SV) is reached.
4) No-standby Action
If an alarm action point is reached when power is applied, an alarm is output. This is used to output an alarm whenever an alarm
action point is reached.
6-2. Setting of Event Standby Action
In the 1-22 event 1 standby action code setting screen in the explanation of the screen group 1:
1) Select a code from 1, 2 and 3 of the standby action code table when event output is used as an alarm;
2) Select 4 when event output is used for control. Note, however, that setting 4 will turn event output OFF if input goes out of
order;
3) When 2 is set, the standby function is put in action only when power is applied;
4) When 3 is set, the standby function is put in action when power is applied and when SV in execution is changed.
5) A change to 1 or 4 while standby action is in execution, the standby action will be released immediately;
6) If a PV value is out of a range in which an event action is ON, standby action becomes invalid even when 2 or 3 has been set for
standby action. The 1-25 event 2 standby action code setting screen is the same.

6-4. P.I.D.
1) P (Proportional action)
A percentage at which control output varies with respect to a measuring range is set. Control output increases or decreases in
proportion to a difference between PV and SV values. The narrower the proportional band, the more conspicuously output
changes to strengthen proportional action. If it is too narrow, however, the result of control will be close to ON-OFF action.
2) I (Integral time)
This is the function to correct an offset (constant deviation). The longer the integral time, the weaker the corrective action and
the shorter the time the stronger the action but control result may be undulated due to integral hunting.
3) D (Derivative time)
This is the function to estimate a change in control output, suppress overshoot caused by integration and improve control
stability. The longer the derivative time, the stronger the derivative action but control result may be vibratile.
6. Explanation of Functions (All the details sre mentioned here except the explanation of 5-5. Procedure of setting
screen group 0)

- 20 -
6-5. Manual Reset
In PID action, an offset is corrected automatically by I, i.e., integration. When OFF is set for I, correction is not carried out and so
output should be increased or decreased manually. This method is called manual reset.
6-6. Lower Limit and Higher Limit Setting Limiters
1) Output limiter means to limit a minimum or maximum value of control output and this function is effective in maintaining the
lowest temperature or suppressing overshooting of control.
2) Output limiter gives preference to a lower limit value. When a larger lower limit value than a higher limit value is set, the higher
limit value is automatically changed to the lower limit value + 1%. In other words, it is not possible to set a higher limit value
which is less than a lower limit + 1%.
6-7. Proportional Cycling Time
It should be within a range from 1~120 seconds in the case of contact output or SSR drive voltage output. Proportional cycling time
is ON time + OFF time within a proportional band.
6-8. Auto Return Function
If no key is operated for 3 minutes or longer on a screen (except the 0-1 output 1 monitor screen, 0-2 output 2 monitor screen and 1-
26 heater current monitor screen), the screen automatically changes to the 0-0 basic screen of the mode 0 screen group. This is called
auto return.
6-9. Control Output Characteristics
1) One output
For heating action, RA (reverse action) OUT 1 is set, and for cooling action DA (direct action) OUT 1 is set.
2) Two outputs
RA (reverse action) is set for heating action OUT1 and cooling action OUT2.
DA (direct action) is set for heating action OUT1 and heating action OUT2.
Control output characteristics with two outputs are shown in the following diagrams. shows heating and cooling control and
two-stage heating control.

6-10. Soft Start
It is the function to raise control output gradually in a set time upon applying power and at the time of return from scaleover to
normal. The function effectively prevents excess current from being present in a heater or the like.
1) The soft start function is put in action in the following conditions:
When power is applied in the automatic output mode and when a normal state is returned from scaleover.
When P (proportional band) is not OFF.
When soft start time has been set, i.e., not OFF.
2) Soft start is released in the following conditions:
Soft start time has elapsed normally.
An output value under soft start control exceeds an PID operated output value.
Soft start time is turned OFF by key operation.
The automatic output mode is changed to the manual output mode by key operation.
AT (auto tuning) is executed by key operation.
The setting of P (proportional band) is changed to OFF by key operation.
The measuring range of input is changed by key operation.
A control output characteristic is changed by key operation.
