Bypass
RW
The normal control algorithm may be bypassed through this
parameter. When bypass is set, the setpoint value (in percent)
will be directly transferred to the output. To prevent a bump
on transfer to/from bypass, the setpoint will automatically be
initialized to the output value or process variable, respectively,
and the path broken flag will be set for one execution.
Uninitialized
Setting:
•
ON: normal control algorithm bypassed, output based on
setpoint
•
OFF: normal control
