Main Screen

Step
“Step” means a process of the program, which
are executed in order from Step 1.
After the temperature is controlled at the set
temperature and the time condition is satisfied,
it proceeds to the next step.
Temperature priority control
Temperature priority control is a control which
enables to keep the set temperature for a set time
after the measured temperature reaches the set
temperature.
Time priority control
Time priority control is a control which enables to
switch to the next step after elapsing the set time.
The temp. is controlled to keep the set temp. during
the period of the set time, and the set time includes
the time for rising and falling of temp. until reaching
the set temp.
Alarm code
Alarm codes means codes which are assigned
to each alarm type.
For details, refer to [5. Alarm Function].
The number of runs can be set in Program
operation and 24-hour cycle operation.
The relationship between the set number of
repetitions and the number of runs is as
follows:
・Run once (no repetition)
Set number of repetitions → 1
・Run between 2 and 99 times
Set number of repetitions → 2 to 99
・Repeat until the control is stopped by
key
Set number of repetitions → ∞

Termination of temp. control
This means that temp. control are finished after
the actual number of runs reaches the number of
repetitions set in Program operation or 24-hour
cycle operation.

Temperature display correction function allows to correct
the display of the temperature measured by temperature
sensor through inputting two points.
The setting of temperature display correction cannot be
changed but the preset values can be checked during
controlling temperature or locking the operation.
3-1 Temperature display correction
Example)
Here, the correction method is explained using an
example described below:
When the temp. measured by this unit is 21.2°C,
and the temp. measured by a reference
thermometer is 22.8°C, and the temp. measured by
this unit is 60.5°C, and the temp. measured by a
reference thermometer is 63.9°C.

※When the output interlock is [---], the analog
output is always 0 mV.
Example)
・Output interlock : Temperature
・Minimum temperature (Xmin) : 40.0℃
・Maximum temperature (Xmax): 200.0℃
・Minimum output (Ymin) : 0 mV
・Maximum output (Ymax) : 8000 mV
With this setting, 0 mV is output when the temperature
is 40°C or less, or 8000 mV is output when the
temperature is 200°C or higher, and the voltage
proportional to the temperature of 50 mV/°C is output in
the range of 40°C to 200°C.

Alarm Functions
5
This unit has the following alarm functions. Codes are allocated to each alarm.
Temperature control cannot be started while alarms occur.
5-1 Types of alarms to be detected
18
Alarm name & code Cause of alarm Factor for cancelling alarm
Door alarm*1
A-2
・When the door is open for a
longer time than the set time during
controlling temperature.
・When temperature control is
started with the door open.
・Automatically cancelled when it is
detected that the door is closed.
・Press Dial key when temperature
control is stopped.
Temperature alarm*2
A-0(H2):
Upper limit 2
A-0(H1):
Upper limit 1
A-0(L1):
Lower limit 1
A-0(L2):
Lower limit 2
After the measured temperature
(PV) reaches the set temperature
(SV) during controlling temperature,
・Upper limit temperature alarm
When the state of PV>SV+H1 or
PV>SV+H2 continues.
・Lower limit temperature alarm
When the state of PV < SV-L1 or
PV < SV-L2 continues.
・Press Dial key while temperature
control is stopped.
・Temperature control is restarted
after temperature control is paused.
・Change the set temperature.
・Upper limit temperature alarm
When the state of PV ≦SV+H1 or
PV≦SV+H2 continues.
・Lower limit temperature alarm
When the state of PV≧SV-L1 or
PV≧SV-L2 continues.
Heater short-circuit, F-6 ・Heater cannot be turned OFF. ・Turn OFF the power. ※3
Heater burnout, F-0 ・Heater cannot be turned ON. ・Turn OFF the power. ※3
Error in temperature
sensor, F-1
When the temperature sensor
detects a temperature which is out
of the display range
When the temperature sensor
detects a temperature which is in the
display range
Uncontrollable
temperature, A-1
When the measured temperature
cannot reach the set temperature
even after temperature control
starts and then a certain period of
time elapses.
・Press Dial key while temperature
control is stopped.
・Temperature control is restarted
after temperature control is paused.
・Change the set temperature.
・PV reaches SV.
Power restoration,
A-4
When the power is restored after a
power shutdown during controlling
temperature.
Only indicate that the power is
restored after a power shutdown and
then temperature control is restarted.
Pressure error, A-16
When the pressure sensor detects
abnormally high pressure
When the pressure sensor doesn’t
detect abnormally high pressure
anymore.
Memory error, F-85 Failed to read or save the internal
memory.
Turn OFF the power. ※3
Circuit board error, F-98 ・Failure in LCD
・Failure in control board of the unit
Turn OFF the power. ※3
※1 Temperature control is paused when “Door open" is detected during controlling temperature.
Temperature control is restarted when it is detected that the door is closed.
If the duration of "Door Open" exceeds the set time for the door alarm, the door alarm occurs.
※2 There are two types of temperature alarm, “Upper limit temperature alarm (overshoot)” and “Lower limit
temperature alarm (undershoot)”, each of which has two levels.
※3 If the same alarm is displayed after the power is turned on again, please contact our service center.
