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
The controller automatically resumes the program operation where it left at the power shutdown. In case
that the temperature inside the chamber is outside the specified temperature range based on the setpoint
temperature, 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 .
The timer built-in the controller does not count as running time for a period of power failure.
In case of power failure during the Auto-Stop operation
The controller automatically resumes the Auto-Stop operation where it 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
. (Forced Wait)
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 that the operation stop time
is set in hours, the timer built in the controller counts as running time for a period of power failure.
When the operation stop time reaches during power failure, the controller stops running just after the
power restoration.
In case of power failure while the controller is in standby condition
In case that the operation start time is set in a period of time, the timer built in the controller does 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
The controller resumes running toward to the preset temperature after the power restoration.
