RAMP/SOAK IN NORMAL OPERATION :
Whatever operation form parameter is ; Normal Ramp/Soak operation is started by selecting
parameter . Ramp led becomes active. Ramp/Soak operation can be paused by
selecting parameter . Ramp/Soak operation can be canceled by selecting
Parameter
While Ramp / Soak operation continues, if parameter is 1-4 numbered, if it is
5-8 numbered, if it is , 1-8 numbered steps run.
When Ramp/Soak operation finishes, device operates in operation form which operation form
device has before Ramp/Soak operation.( Or )
If selection of operation form parameter before starting to Ramp/Soak operation is then
device continues to run from set value.
If any Ramp time or Soak time is , then relevant ramp or soak step is skipped.
If there is a sensor break failure, while Ramp/Soak operation is running or if power off while
Ramp/Soak operation is running.
Ramp/Soak operation is canceled
70
While any Ramp/Soak function is running, changing relevant time set value can
cause unexpected effects in set value and process output.
RAMPACTION DURING POWER ON (SOFT- START )
Then Soft-Start operation is canceled.
If parameter is different from and selection of operation form parameter is
,Then Soft-Start starts to run. Ramp led blinks. By increasing the process output for
Parameter , process output reaches to the %output value that is measured when power first
applied to the device at the end of the time. When Soft-Start operation finishes, if operation
form of the device is , device continues to run from value.
If selection of operation form parameter is adjusted as
If time is adjusted to a value that is less than the counted value or
If there is a sensor break failure
If Ramp / Soak tolerance parameter is , then it has no function. When it
is different from 0 (While Ramp/Soak is running)
Process Value condition
is not true (process value is out of the tolerance), time counting is stopped till the
condition is true.
