The temperature of MV does not increase.
Cause Countermeasure
Power is not supplied to the heaters.
Check the wiring to the heaters, and supply power to the heaters.
Signals from the temperature regulators
are not input to the SSRs or the power
regulators.
Correctly wire the devices.
The temperature switch in MV
functioned.
The self-hold type temperature switch is used.
The return method of a temperature switch needs to lower the
stoppage of deliveries of the heater power supply to MV, and a
temperature switch to below return temperature.
After the heater power supply to MV has carried out stoppage of
deliveries, please wait for about 1 hour.
Please contact us, when you still shut off after a temperature fall
and a heater power supply when temperature does not rise, and
you check heater resistance and there is no electrical connection
of a heater.
The heater power supply shorted out.
Turn off power, and check the heater power line.
Setting data has not been input to the
temperature regulators.
Input the specified setting data to the temperature regulators.
The temperature of MV does not stabilize. The temperature is not restored. (During
vaporization)
Cause Countermeasure
The material was fed in a quantity
exceeding the vaporization limit.
Forcibly close the valve of MV before starting vaporization.
(See page 6.)
The flow rate is not stable.
See the countermeasure stated in the following item “The flow
rate indication does not stabilize.”
The liquid is not vaporized inside. The
vapor is condensed.
Check the secondary pressure, temperature and warm-up time.
