CnF. 4
NOTES:
1) When open loop servomotor control drive without valve
position indication is configured, this parameter is forced to
“buñ.” and it cannot be modified.
2) When open loop servomotor control drive with valve position
indication is configured and the transfer from AUTO to MAN
is required, the instrument is able to reach the value
programmed by this parameter using temporarily the valve
position value as a feedback.
- MANUAL to AUTO transfer type - [C.G05]
This parameter will be available only when at least one control
output is configured and manual function is enabled (“ñAn.F”
[C.G03] = “Enb”)
Range: buñ.
= Bumpless balance transfer.
buñ.b = Bumpless balanceless transfer (the operative
set point is aligned to the measure value).
NOTES:
1) The “alignment” is not performed if measure is in error
condition or Remote Set point is selected.
2) The selected local set point will be changed even if it is
software protected.
General note about the instrument restarting
The two following parameters are used to set the instrument
restarting after a power down:
- the St.Pr [C.G07] parameter setting is used to the instrument
restart when a program was running.
- the St.Fn [C.G06] parameter setting is used to all the other
cases.
- Device status at start up when it works as
controller - [C.G06]
This parameter will be available only when at least one control
output is configured and manual function is enabled (“ñAn.F”
[C.G03] = “Enb”).
Range: Auto
= It starts always in auto mode
ñan = It starts always in manual mode with power
output set to 0.
Cnd.A = It starts in the same way it was left prior to
power shut down (if in manual mode the power
output is set to 0).
Cnd.b = It starts in the same way it was left prior to
power shut down (if in manual mode the power
output will be equal to the last value prior to
power shut down).
