Function:
The operation of this instrument is not affected by a power failure of 4 ms or less.
The control start mode at power recovery after more than 4 ms power failure can be
selected as follows.
Action when power
failure recovers
Operation mode when power
failure recovers
Output value when power
failure recovers
Hot start 1 Same as that before power failure Near the output value before power failure occurs.
Hot start 2 Same as that before power failure
Auto mode
Value as a result of control
computation
2
Manual mode Output limiter low
Cold start Manual Output limiter low

Even when control is started by switching from STOP to RUN with the operation mode set to “Control,” operation will take place in the
start mode selected with Hot/Cold start.

The result of control computation varies with the control response parameter.
