P6 = Valve position indication.
This parameter is available only if P5 =
sm.Ol
.
fb
= the valve position will be displayed
no.fb
= the valve position will not be displayed (the
feedback potentiometer can be omitted)
P7 = Output 3 function.
none
= output not used.
al1.p
= it is used as Alarm 1 output and the
alarm 1 is programmed as process
alarm.
al1b
= it is used as Alarm 1 output and the
alarm 1 is programmed as band alarm.
al1.d
= it is used as Alarm 1 output and the alarm
1 is programmed as deviation alarm.
rEU
= it is used as second time proportional
control output with reverse action.
dir
= it is used as second time proportional
control output with direct action.
NOTES:
1) If P7 is changed to "
rEU
" the cycle time (
Cy3
) will
be forced to 15 s
2) If P7 is changed to "
dir
" the cycle time (
Cy3
)
will be forced to: 10 s when P25 =
Air
4 s when P25 = OIL
2 s when P25 = H2O
3) Only one of the two outputs (see P5 and P7)
can be configured as "
rEU
" control output.
4) Only one of the two outputs (see P5 and P7)
can be configured as "
dir
" control output.
5) If the servomotor output is selected (P5 ="
sm.Ol
"
or "
sm.Cl
") the OUT 3 can be set as alarm output
only (P7 = "
al1.p
" or "
al1.b
" or "
al1.d
").
P8 = Alarm 1 operating mode
Available only when P7 is equal to
al1.p
,
al1.b
or
al1.d
.
H.A.
= High alarm (outside for band alarm) with
automatic reset.
l.a.
= Low alarm (inside for band alarm) with
automatic reset.
h.l.
= High alarm (outside for band alarm) with
manual reset (latched).
l.l.
= low alarm (inside for band alarm) with
manual reset (latched).
P9 = Alarm 2 function (OUT 4).
none
= output not used.
al2.p
= it is used as Alarm 2 output and the alarm
2 is programmed as process alarm.
al2.b
= it is used as Alarm 2 output and the
alarm 2 is programmed as band alarm.
al2.d
= it is used as Alarm 2 output and the alarm
2 is programmed as deviation alarm.
NOTE : The output 4 operates as a logic OR
between the alarm 2 and the alarm 3.
P10 = Alarm 2 operating mode
Available only when P9 is different from "
none
".
H.A.
= High alarm (outside for band alarm) with
automatic reset.
l.a.
= Low alarm (inside for band alarm) with
automatic reset.
h.l.
= High alarm (outside for band alarm) with
manual reset (latched).
l.l.
= low alarm (inside for band alarm) with
manual reset (latched).
P11 = Alarm 3 function (OUT 4)
none
= output not used.
al3.p
= it is used as Alarm 3 output and the alarm
3 is programmed as process alarm.
al3.b
= it is used as Alarm 3 output and the
alarm 3 is programmed as band alarm.
al3.d
= it is used as Alarm 3 output and the alarm
3 is programmed as deviation alarm.
NOTE : The output 4 operates as a logic OR
between the alarm 2 and the alarm 3.
