Feedback (FEEDBACK)
[2]
Function:
This parameter allows a choice between the
different functions available for the input, terminal 1.
Scaling of the input signal is effected in parameters
338 and 339.
Description of choice:
No operation.
Is selected if the FCM 300 is not to
react to signals connected to the terminal.
Reference
. Is selected to enable change of
reference by means of an analog reference signal.
If other inputs are connected, these are summed,
taking account of their signs.
Feedback.
Is selected if closed loop regulation with
an analog signal is used.

more than one terminal, these signals will be
summed.
317 Time out

[10]
Function:
If the value of the reference signal connected to the
input, terminal 1, falls below 50% of the setting in
parameter 336 for a period longer than the time set
in parameter 317, the function selected in
parameter 318 will be activated.
Description of choice:
Set the desired time.
318 Function after time out
(LIVE ZERO FUNCT.)
Settings:

Stop and trip (STOP AND TRIP)
[5]
Function:
This parameter allows a choice of the function to be
activated if the value of the reference signal
connected to the input, terminal 1, falls below 50%
of the setting in parameter 336 for a period longer
than the time set in parameter 317.
If a time-out function (parameter 318) occurs at the
same time as a bus time-out function (parameter
514), the time-out function (parameter 318) will be
activated.
