Operation Course/Function List
The operation functions of this unit are as follows;
Name Description Page
Forced cooling function
This function turns on the cooling fan during exhaust process to
shorten the cooling time.
The cooling fan is turned on during switching to the exhaust
process in the apparatus sterilization course. In other courses, it
starts to run at the saturated vapor temperature of -2℃ or less.
It stops when the equipment goes into the standby state after
operation is completed, or when the temperature inside the
chamber reaches 60℃.
The COOLING FAN key can be set anytime before and during
operation of equipment.
Pressing the COOLING FAN key lights the COOLING FAN lamp
and makes the function available.
Preheating function
This function keeps the temperature of feedwater inside the
chamber with the preset temperature.
The range of preset temperature is from 45℃ to 80℃. The
operation automatically ends after five hours.
Pressing the PRE HEAT key lights the PRE HEAT lamp. The
preset temperature is displayed with blinking. Set the desired
value and then press the ENTER key. This enables the function.
34
Memory function
Each operation course has three memory banks, where
registration and read of settings are possible. The following
settings can be stored into the memory.
・
Sterilization (melting) temperature
・ Sterilization (melting) time
・ Heat-retention temperature
・ Heat-retention time
・ ON/OFF of forced cooling function
35
Auto start function
This function automatically starts the operation of equipment at
the specified time with the selected course.
The time can be set in increments of one minute within the range
from 00：00 to 23：59.
36
Sample temperature
function (optional)
This function counts the sterilization/melting time by the
temperature measured by the sample temperature sensor
(optional).
Pressing the SAMPLE key lights the SAMPLE lamp. The
temperature display screen indicates the temperature measured
with the sample temperature sensor.
37
Temperature output
terminal (optional) This function transmits and output the measured temperature of
controller at 4～20 mA.
Time up output terminal
(optional) This function outputs the relay (“a” contact) at operation end.
Contact spec: AC250V 1A (resistance load)
Alarm output terminal
(optional)
This function outputs the relay (“a” contact) at warning of
controller.
Contact spec: AC250V 1A (resistance load)
