P7 = analog retransmission - initial scale
value.
Available only when P5 = Pv.rt or SP.rt.
It is programmable from -1999 to 4000.
The decimal point will be positioned as selected
with P2 parameter.
P8 = analog retransmission - full scale value.
Available only when P5 = Pv.rt or SP.rt.
It is programmable from -1999 to 4000.
The decimal point will be positioned as selected
with P2 parameter.
P9 = Output 2 function.
nonE = output not used.
rEv
= Out 2 is used as control output with
reverse action.
dir = Out 2 is used as control output with direct
action.
AL1.P =it is used as Alarm 1 output and the
alarm 1 is programmed as process alarm.
AL1.b = 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
alarm1 is programmed as deviation alarm.
NOTE: If P9 has been changed to "rEv", the
cycle time (Cy2) will be forced to 15
seconds.
If P9 has been changed to "dir", the cycle
time (Cy2) will be forced to:
10 s when P22 is equal to "AIr"
4 s when P22 is equal to "OIL"
2 s when P22 is equal to "H2O".
P10 = Alarm 1 operating mode
Available only when P9 is equal to "AL1.P",
"AL1.b" or "AL1.d".
H.A. = High alarm (outside for band alarm) with
automatic reset (latched).
L.A. = Low alarm (inside for band alarm) with
automatic reset (latched).
H.L. = High alarm (outside band) with manual re-
set (latched).
L.L. = Low alarm (inside band) with manual reset
(latched).
P11 = Output 3 function
nonE = output not used.
rEv
= Out 3 is used as control output with
reverse action.
dir = Out 3 is used as control output with direct
action.
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.
NOTES: 1) If P11 has been changed to "rEv", the
cycle time (Cy3) will be forced to 15
seconds.
If P11 has been changed to "dir", the
cycle time (Cy3) will be forced to:
10 s when P22 is equal to "AIr"
4 s when P22 is equal to "OIL"
2 s when P22 is equal to "H2O".
2) The relations among P5, P9 and P11
are shown by the following notes:
- one Out only can be configured as
"rEv" output.
- one Out only can be configured as
"dir" output.
- if no Output is configured as control
output the instrument will operate as
an indicator.
