Standby setting (Settings: oFF/on)
[Description]
• This parameter switches the control between RUN and
Standby.
• During standby, the control output and the alarm output
stay OFF, like the standby for ramp-soak operation.
Retransmission output is kept operated. (However, if the
type of retransmission output is set to the MV, it becomes
4mA or lower.)
• While the alarm with a hold is selected, the hold function
takes effect after changing the Standby setting from ON
to OFF.
• is displayed during the standby for ramp-soak
operations or the controller changes to the standby state
in case of the occurrence of errors.
[Setting example] Starting the control
• The other operations are the same as those of the ramp-
soak standby.
• The setting of ON/OFF for standby is saved after power-
off.
• When the standby is set to ON during the auto-tuning,
self-tuning, and ramp-soak operations, those operations
will stop. (The PID constant will not be renewed.) Even
through it is set to OFF later, the auto-tuning, self-tuning,
and ramp-soak operations will not be re-started.
• During standby, the ON-delay timer is reset. When
returning to RUN from the standby state, the timer will
start from the beginning.
• The SV lamp flickers only when standby state.
