Caution for using
Factory default
It may cause malfunction if above instructions are not followed.
2. Parameter 2group
1. The connection wire of this unit should be separated from the power line and high voltage line in order to
prevent from inductive noise.
2. For crimp terminal, select following shaped terminal (M3).
3. Please install power switch or circuit-breaker in order to cut power supply off.
4. Install power switch or circuit-breaker to supply or cut off the power.
Switch or circuit-breaker should be installed near by users for convenient control.
5. Do not use this product as Volt-meter or Ampere-meter, this is a temperature controller.
6. In case of using RTD sensor, 3 wire type must be used. If you need to extend the line, 3 wires must be used
with the same thickness as the line. It might cause the deviation of temperature if the resistance of line is different.
7. In case of making power line and input signal line closely, line
fi
lter for noise protection should be installed
at power line and input signal line should be shielded.
8. Keep away from the high frequency instruments.(High frequency welding machine & sewing machine, large
capacity SCR controller)
9. When supplying measuring input, if '
HHHH
' or '
LLLL
' is displayed, measuring input may have problem.
Turn off the power and check the line.

3)Sensor break alarm
The function that alarm output will be ON when sensor is not connected or when sensor's disconnection is
detected during temperature controlling. You can check whether the sensor is connected with buzzer or other
units using alarm output contact. It is selectable between standard alarm [
SBA.A
] or alarm latch [
SBA.B

4)Loop break alarm(LBA)
It checks control loop and outputs alarm by temperature change of the subject. For heating control(cooling
control), when control output MV is 100%(0% for cooling control) and PV is not increased over than LBA
detection band [
LBA.B
] during LBA monitoring time [
LBA.T

SSrM
]
This SSRP output is a user selectable output type which phase control and cycle control are added to
standard SSR drive output.
It is available to standard SSR drive by inner parameter set, Cycle control by connected Zero Cross Turn-
on type SSR, and Phase control by connected Random Turn-on type SSR.
Realizing high accuracy and cost effective temperature control with both current output (4-20mA) and
linear output(cycle control and phase control)
8. Manual reset[
REST
]
When selecting P/PD control mode, certain temperature
difference exists even after PV reaches stable status
because heater's rising and falling time is inconsistent
due to thermal characteristics of controlled objects, such as
heat capacity, heater capacity.
This temperature difference is called offset and manual reset
[
REST
] function is to set/correct offset.
When PV and SV are equal, reset value is 50.0%. After
control is stable, PV is lower than SV, reset value is over
50.0% or PV is higher than SV, reset value is below 50.0%.
Set below 50.0 as reset value

8. Input correction
[
IN-B
]
Controller itself does not have errors but there may be error by external input temperature sensor.
This function is for correcting this error.
Ex) If actual temperature is 80ºC but controller displays 78ºC, set input correction value [
IN-B
] as '002'
and controller displays 80ºC.
As the result of input correction, if current temperature value (PV) is over each temperature range of
input sensor, it displays '
HHHH
' or '
LLLL
'.
9. Input digital fi lter
[
MAvF
]
If current temperature (PV) is
fl
uctuating repeatedly by rapid change of input signal, it re
fl
ects to MV
and stable control is impossible. Therefore, digital
fi
lter function stabilizes current temperature value.
For example, set input digital
fi
lter value as 0.4 sec, and it applies digital
fi
lter to input values during 0.4
sec and displays this values. Current temperature may be different by actual input value.
1. Auto tuning [
AT
]
Auto tuning measures the control subject’s thermal characteristics and thermal response rate, and then
determines the necessary PID time constant. (When control type[
C-MD
] is set as
PID
, it is displayed.)
Application of the PID time constant realizes fast response and high precision temperature control.
If error [
OPEN
] occurs during auto tuning, it stops this operation automatically. To stop auto tuning, change
the set as “OFF”. (It maintains P, I, D values of before auto tuning.)
2. Hysteresis [
HYS
]
In case of ON/OFF control, set between ON and OFF
intervals as hysteresis. (When control type[
C-MD
] is set as
ONOF
, it is displayed.) If hysteresis is too small, it may cause
control output hunting (takeoff, chattering) by external noise,
etc.
