Ranges:
- From P2 to P3 for process alarm.
- From 0 to 500 units for band alarm.
- From -199 to 500 units for deviation
alarm.

HSA

Alarm  hysteresis (in % of P3 - P2 span)
This parameter is present if an alarm  is
configured.
Range:From 0.1% to 10.0% of the input
span or 1 LSD.

Note

: If the hysteresis of a band alarm is

larger than the alarm band, the
instrument will use an hysteresis value
equal to the programmed band minus 1
digit.

Pb

Proportional band (in % of P3 - P2 span)
Range

:

 from 1.0 % to 99.9 % of span for

heating output.
When PB parameter is set to 0, the
instrument performs an ON-OFF control;
the  ti, td, C, OLH and tOL parameters
are skipped and SMART function is
disabled.

HS

Hysteresis for ON/OFF control action (in
% of P3 - P2 span)
This parameter is available only when
Pb=0.
Range: from 0.1% to 10.0% of the input
span.

ti

Integral time (in minutes and seconds
[mm.ss]). This parameter is skipped if
Pb=0 (ON/OFF action).
Range: from 00.1 to 20.0 [mm.ss]. Above
this value the display blanks and integral
action is excluded

td

Derivative time (in minutes and seconds
[mm.ss]). This parameter is skipped if
Pb=0 (ON/OFF action).

Range: from 1 s to 9 min. and 59 s; if 0 is
set, the derivative action is excluded.

IP

Integral pre-load
This parameter is skipped when PB = 0.
Range:
- from 0 to 100% for one control output

C

Output 1 (heating) cycle time (in
seconds)
This parameter is present if PB
parameter is different from 0 only.
Range:From 1 to 200 s.

rL

Set point low limit (in eng. units).
Range: from min. range value (P2) to rH.

Note

: When P2 has been modified, rL

will be realigned to it.

rH

Set point high limit (in eng. units).
Range:from rL to full scale value (P3).

Note

: When P3 has been modified, rH

will be realigned to it

OLH

Output high limit (in % of the output).
This parameter is present if PB
parameter is different from 0 only.
Range: from 0.0 to 100.0

tOL

Time duration of the output power limiter.
The tOL is a programmable time in which
the output level is limited to OLH value.
This timer starts at instrument power up if
the measured variable is less than the
threshold value programmed (P10
parameter).
This parameter is present if PB
parameter is different from 0.
Range: from 1 minute to 100 minutes.
Above "100", the upper display shows
"InF" and the "OLH" limit will always be
enabled independently from P10
parameter value.

Note

: The tOL can be modified but the

new value will become operative only at
