[14] o2F - Out 2 function
Available:
When the instrument has out 2 option.
range: none
= Output not used.
With this setting the status of this output
can be driven directly from serial link;
h.reg
= Heating output;
c.reg
= Cooling output.
wArning!
When using the servomotor control,
both
out 1
and
out 2
must be selected as Heating or Cooling
(o1F = o2F = HrEG
or
o1F = o2F = c rEG),
parameter
[39] cont
must be set as
3pt
and
must also be set the potentiometer usage with
parameter
[58] - pot
(none, close loop, open loop).
[15] o3.AL - Alarms linked up with Out 3
Available:
Always.
range:
0... 31 with the following rules:
+1
Alarm 1;
+2
Alarm 2;
+4
Loop break alarm;
+8
Sensor break alarm (burn out);
+16
Potentiometer break alarm.
e.g.:
o3.AL = 3 (1+2) = Alarm 1 + Alarm 2.
o3.AL = 13 (1+4+8) = Alarm 1 + Loop break alarm +
Sensor break alarm.
[16] o3Ac - Out 3 action
Available:
Always.
range: dir
=
Direct action;
reu
= Reverse action;
dir.r
= Direct action with reverse LED indication;
reu.r
= Reverse action with reverse LED indication.
[17] o4.AL - Alarms linked up with Out 4
Available:
Always.
range:
0... 31 with the following rules:
+1
Alarm 1;
+2
Alarm 2;
+4
Loop break alarm;
+8
Sensor break (burn out);
+16
Potentiometer break alarm.
[18] o4Ac - Out 4 action
Available:
Always.
range: dir
=
Direct action;
reu
= Reverse action;
dir.r
= Direct action with reverse LED indication;
reu.r
= Reverse action with reverse LED indication.

Al1 group - Alarm 1 parameters
[19] AL1t - Alarm 1 type
Available:
Always.
range:
nonE = Alarm not used;
LoAb = Absolute low alarm;
HiAb = Absolute high alarm;
LHAo = Absolute band alarm with alarm indication
out of the band;
LHAi = Absolute band alarm with alarm indication
inside the band;
SE.br = Sensor break;
LodE = Deviation low alarm (relative);
HidE = Deviation high alarm (relative);
LHdo = Relative band alarm with alarm indication
out of the band;
LHdi = Relative band alarm with alarm indication
inside the band;
notes: 1.
The relative and deviation alarms are “relative” to
the operative set point value.

[20] Ab1 - Alarm 1 function
Available:
When [31] AL1t is different from
nonE
.
range:
0... 15 with the following rules:
+1
Not active at power up;
+2
Latched alarm (manual reset);
+4
Acknowledgeable alarm;
+8
Relative alarm not active at set point change.
example:
Setting Ab1 equal to 5 (1+4) the alarm 1 will be
“not active at power up” and “Acknowledgeable”.
notes: 1.
The “not active at power up” selection allows to
inhibit the alarm function at instrument power up
or when the instrument detects a transfer from:
•
Manual mode (oPLo) to auto mode;
•
Stand-by mode to auto mode.
The alarm will be automatically enabled when the
measured value reaches, for the first time, the
alarm threshold ±hysteresis (in other words, when
the initial alarm condition disappears).

A “Latched alarm” (manual reset) is an alarm
that will remain active even if the conditions that
generated the alarm no longer persist. Alarm
reset can be done only by an external command
(
button, digital inputs or serial link).

An “Acknowledgeable” alarm is an alarm that can
