When the EXCEED lamp is ON but PV is Higher than SP,
the upper display will be in green value and it shows that the
PV is in the hysteresis area.
[34] r.md – Limit output status at power ON (Re-
start mode)
Available:
Available: always
Range:
0 =
limit output is ON in any cas
1 =
Limit output is OFF at power on when PV
doesn’t exceed SP.
[35] HyS – Hysteresis of the control output
Available:
Available: always
Range:
In engineering unit from 0.0 to 100 % of the input
span
[36] oP.SL – Operating display selection.
Available:
Available: always
Range:
Range:
PU.SP = (0) PV (upper display) and SP (lower
display)
PU
= (1) SP only (lower display)
Note:
When you change the [37] SPLL value, the nstrument
checks the local set points (SP parameters). If SP
is out of this range, the instrument forces it to the
maximum acceptable value
[37] SPLL – Minimum set point value
Available:
Available: always
Range:
from -1999 to [38] SPHL
Note:
When you change the [37] SPLL value, the instrument
checks the local set points (SP parameters). If SP
is out of this range, the instrument forces it to the
minimum acceptable value.
[38] SPHL – Maximum set point value
Available:
Available: always
Range:
from [37] SPLL to 9999.
[39] SP - Set point.
Available:
Available: always
Range:
from [37] SPLL to [38] SPHL
[40] diS– the way of confi rming operation
Available:
Available: always
Range:
but =
by keyboard
di =
by digital input
[41] tim – time duration of the last exceeded period.
Available:
Available: always but it is a read only parameter.
Range:
from 00.00 to 99.59 (HH.mm).
[42] Hi- maximum measured value
Available:
Available: when [33] Hi.Lo = Hi (high limit) but it is
a read only parameter.
Range:
Engineering unit within the input range
[43] Lo – minimum measured value
Available:
Available: when [33] Hi.Lo = Lo (low limit) but it is
a read only parameter.
Range:
Engineering unit within the input range.

PAn group - Operator HMI
[44] PAS2 - Level 2 password:
Available:
Always.
Range:
oFF =
Level 2 not protected by password
(as level 1 = Operator level) 1 to 200.
[45] PAS3 - Level 3 password:
Complete confi guration level
Available:
Always.
Range:
3 to 200.
Note:
Setting [44] PAS2 equal to [45] PAS3, the level 2 will
be masked.
[46] di.CL - Display color
Available:
Always.
Range:
0 =
the display color is used to show the
Exceed condition.
When no exceed condition is present, the
upper display will be green.
when [33] Hi.Lo = Hi (high limit ) and PV >
SP the upper display will be red.
when [33] Hi.Lo = Lo (low limit ) and PV <
SP the upper display will be red.
1 =
Display red (fi x);
2 =
Display green (fi x);
3 =
Display orange (fi x).
[47] diS.t - Display time out
Available:
Always.
Range:
oFF =
The display is ever ON;
0 (OFF) to 99.59 minutes and seconds.
Note:
This function allows to turn OFF the display when no
alarm is present and no action is made on the instrument.
When diS.t is different from OFF and no button is
pressed for more than the programmed time out, the
display goes OFF and only 4 segments of the less
signifi cant digit are turned ON in sequence in order to
show that the instrument is working correctly.
If an alarm occurs or a button is pressed, the display
will come back to the normal operation.

Ser group - Serial link parameter
[48] Add - Instrument address
Available:
Always.
Range:
oFF =
Serial interface not used;
1 to 254.
[49] bAud - Baud rate
Available:
When [48] Add different from oFF.
Range:
1200 = 1200 baud;
2400 = 2400 baud;
