Param.Description
SP Main set point Main set point Main set point Main set point Main set point
Range: from rL to rH.
Manual reset of the alarms Manual reset of the alarms
n.rS Manual reset of the alarms Manual reset of the alarms Manual reset of the alarms
This parameter is available only when one
alarm with manual reset has been
programmed.
Set ON and push the FUNC push-button
to reset the alarms.
nnn Software key for parameter protection Software key for parameter protection. Software key for parameter protection Software key for parameter protection Software key for parameter protection
This parameter is skipped if P18 = 0 or 1.
The instrument will shows the safety key
status:
ON = the instrument is in LOCK condition
OFF = the instrument is in UNLOCK
condition
When it is desired to switch from LOCK to
UNLOCK condition, set a value equal to
P18 parameter
When it is desired to switch from UNLOCK
to LOCK condition, set a value different
from P18 parameter.
A1 Alarm 1 Alarm 1 Alarm 1 Alarm 1 Alarm 1 threshold value threshold value threshold value threshold value threshold value
This parameters is present if the alarm 1
is configured only.
Ranges:
- From P2 to P3 for process alarm.
- From 0 to 500 units for band alarm.
- From -199 to 500 units for deviation
alarm.
Alarm 2 Alarm 2 threshold value threshold value
A2 Alarm 2 Alarm 2 Alarm 2 threshold value threshold value threshold value
For other details see A1 parameter.
H1 Alarm Alarm Alarm Alarm Alarm 1 hysteresis 1 hysteresis 1 hysteresis 1 hysteresis 1 hysteresis
This parameters is present if the alarm 1
is configured only.
Range: From 0.1% to 10.0% of the input
span or 1 LSD.
Note Note Note Note: If the hysteresis of a band alarm is Note
larger than the alarm band, the instrument
will use an hysteresis value equal to the
programmed band minus 1 digit.
H2 Alarm Alarm Alarm Alarm Alarm 2 hysteresis 2 hysteresis 2 hysteresis 2 hysteresis 2 hysteresis
For other details see H1 parameter.
Pb Proportional band. Proportional band. Proportional band. Proportional band. Proportional band.
Range: : : : : from 1.0 % to 99.9 % of span for
heating output.
From 1.5 % to 99.9 % of span for heating/
cooling output.
When Pb parameter is set to 0, the
instrument performs an ON-OFF control;
the ti, td, IP, C, C2, rC, OLP, OLH and
tOL parameters are skipped and SMART
function is disabled.
Note Note
Note Note: When SMART is enabled, the Pb Note
parameter range is limited by P27, P28 and
P29 parameters.
HS Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action
Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action
It is available only when Pb=0.
Range: from 0.1% to 10.0% of the input
span.
Integral time Integral time
ti Integral time Integral time Integral time
"ti" 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
Note Note Note Note Note: When SMART is enabled, the mini-
mum value of the integral time is limited by
P30 parameter.
td Derivative time Derivative time Derivative time Derivative time Derivative time
"td" is skipped if Pb=0 (ON/OFF action).
Range: from 0.01 to 9.59 m.ss. Setting the
0 value the derivative action is excluded.
Note: When SMART is enabled the td Note Note Note Note
value will be equal to 1/4 of the integral
time.
