REMOTE SET POINT REMOTE SET POINT REMOTE SET POINT REMOTE SET POINT REMOTE SET POINT
The device can be equipped with a remote set point.
This feature must be configured (see “A.In.F / A.In.t / A.I.FL /
A.I.Añ / L.r.Oñ “ CnF.1 and “d1.Fn / d2.Fn” CnF.5 )
If “A.I.Añ” = norñ the remote set point can be activated only
only only only only
by selected external contact (If none digital input is configured
to select from Local / Remote set point, the Remote set point
will be always active and
always active and always active and always active and always active and will be the only SET POINT the only SET POINT the only SET POINT the only SET POINT the only SET POINT
present on the device.)
If the auxiliary input is out of range or open the control output
is de-activated (see “Control Action Feature”)
If “A.I.Añ” = Cnd.A the remote set point is activated by status
of auxiliary input
(Remote set point if auxiliary input is in range, local set point if
it is out of range or open)
When remote set point is selected the decimal point at right
hand of LSD on middle display is steady lit.(when device is in
“Normal display mode”)
The scale for remote set point is fixed and equal to primary
control variable; the set point value will be further limited by
“rL/ rH”. The sampling rate is 1.125 mS
The value can be filtered.
When transfer from Remote to Locale setpoint is made(by
external contact), the local setpoint can be aligned to last
remote setpoint value (see L.r.Oñ – CnF.1)
When remote set point value is displayed on lower display (see
“DISPLAY FUNCTION”)
the out of range condition are displayed as follow:
OVER-RANGE ( “
****”), UNDER-RANGE ( “-***”), leads
break (“ OPEn” ).
