[14] o2F - Output 2 function
Available: When the out2 is a relay output (hardware):
Range: nonE Output not used;
H.rEG Heating output (reverse);
c.rEG Cooling output (direct).
m
When using the servomotor control, both Out1 and
Out2 are to be selected as Heating or Cooling
(o2F = o3F = HrEG or o2F = o3F = crEG);
Parameter [39] cont must be set as 3pt.
[15] o3.AL - Alarms linked up with Out 3
Available: Always.
Range: 0... 31 with the following rule:
+1 Alarm 1;
+2 Alarm 2;
+4 Loop break alarm;
+8 Sensor break (burn out);
+16 Potentiometer 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.
Notes: 1. Direct action: the output repeats the status of the
driven element.
Example: the output is an alarm output with direct
action. When the alarm switches to ON, the relay
is energized.
2. Reverse action: the output status is the opposite
of the status of the driven element.
Example: the output is an alarm output with
reverse action. When the alarm is OFF, the
relay is energized. This setting is usually named
“fail-safe” and it is generally used in dangerous
process in order to generate an alarm also when
the instrument power supply goes OFF or the
internal watchdog starts.
[17] o4.AL - Alarms linked up with Out 4
Available: Always.
Range: 0... 31 with the following rule:
+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.

trol output:
nonE Alarm not used;
LoAb Absolute low 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.
• When no output is programmed as control output:
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;

Notes: 1. The relative and deviation alarms are “relative” to
the operative set point value.

[20] Ab1 - Alarm 1 function
Available: When [19] AL1t is different from nonE.
Range: 0... 15 with the following rule:
+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).
