Behavior after Power Restoration
In case of power failure during operation, the controller resumes the following operations after the
power restoration.
In case of power failure during the program operation
1. The controller automatically resumes the program operation when it left at the power shutdown.
2. When the controller does not resumes the program operation automatically,
※
In case that the temperature inside the chamber is outside the specified temperature range based
on the setpoint temperature, the controller foes to the FORECED WAIT STATE until the
temperature inside the chamber comes back to the specified temperature range. When you select
the display of the remaining time by pushing the Display key in this condition, the sub display
shows
.
The timer built-in the controller dose not count as running time for a period of power failure.
Therefore the rest time just before the power failed is the same time as the rest time just after the
power recovered.
In case of power failure during the Auto-Stop operation
The controller automatically resumes to the standby when the Auto-Stop operation left at the power
shutdown.
※
In case that the temperature inside the chamber is outside the specified temperature range based
on the setpoint temperature after the power restoration, the controller goes to the FORECED
WAIT STATE until the temperature inside the chamber comes back to the specified temperature
range. When you select the display of the remaining time by pushing the Display key in this
condition, the sub display shows
.
In case that the operation stop time is set in a period of time, the timer built in the controller does
not count as running time for a period of power failure. On the contrary, in case
The timer built-in the controller dose not count as running time for a period of power failure.
Therefore the rest time just before the power failed is the same time as the rest time just after the
power recovered.
In case of power failure while the controller is in standby condition
The controller automatically returns to the standby condition when the standby condition of
auto-start and programmed auto-start left at the power shutdown.
※
In case that the operation start time is set in a period time, the timer built in the controller dose not
count as standby time for a period of power failure. On the contrary, in case that the operation
start time is set in hours, the timer built in the controller counts as standby time for a period of
power failure.
When the operation start time reaches during power failure, the controller starts running just after
the power restoration.
In case of power failure during the fixed temperature operation and a soak period of the
Auto-Start operation
When power restoration occurs for the operation that is independent upon time such as the fixed
temperature or a soak period of the Auto-Start operation, the controller resumes running toward to
the preset temperature.
