Pb Proportional band
Range: from 1.0% to 200.0% of the input span.
When Pb parameter is set to zero, the control
action becomes ON-OFF.
Note: When device is working with SMART
algorithm the Pb value will be limited by P34
and P35 parameters.
HYS Hysteresis for ON/OFF control action
This paameter is available only when Pb=0.
Range: from 0.1% to 10.0% of the input span.
ti Integral time
This parameter is skipped if Pb=0 (ON/OFF
action).
Range: from 0.0 to 10.0 [mm.ss]. Above this
value the display blanks and integral action is
excluded
Note: When the device is working with SMART
algorithm, the minimum value of the integral
time will be limited by P36 parameter.
td Derivative time
This parameter is skipped if Pb=0 (ON/OFF
action).
Range:From 00.00 to 10.00 mm.ss.
Notes:
1)When device is working with SMART
algorithm the td value will be equal to a quarter
of Ti value.
2)When P44 is equal to "Pi", the derivative
action is always excluded.
IP Integral pre-load
This parameter is skipped if Pb=0 (ON/OFF
action).
Ranges:
- From 0.0 to 100.0 % of the output if device is
configured with one control output.
- From -100.0% to 100.0% of the output if device
is configured with two control outputs.
Sñ.tt Servomotor travel time
This parameter is available only when
P5 = Sñ.OL.
Range: from 0.06 to 3.00 [mm.ss].
Sñ.db Servomotor dead band .
This parameter is available only when
P5 = Sñ.CL or Sñ.OL and Pb is different from 0.
Range: from 1% to 50 % of the travel timo or of
the feedback potentiometer span.
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.
AL1 Alarm 1 threshold
This parameter is available only if P 7 is equal
to "AL1.P", "AL1.b" or "AL1.d".
Ranges:
- Span limits for process alarm.
- From 0 to 500 units for band alarm.
- From -500 to 500 units for deviation alarm.
HSA1 Alarm 1 hysteresis
This parameter is available only if P 7 is equal
to "AL1.P", "AL1.b" or "AL1.d".
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.
AL2 Alarm 2 threshold
This parameter is available only if P 9 is equal
to "AL2.P", "AL2.b" or "AL2.d".
For other details see AL1parameter.
HSA2 Alarm 2 hysteresis
This parameter is available only if P 9 is equal
to "AL2.P", "AL2.b" or "AL2.d".
For other details see HSA1parameter.
AL3 Alarm 3 threshold
This parameter is available only if P 11 is equal
to "AL3.P", "AL3.b" or "AL3.d" and P13 = OPrt
or SPEC.
For range details see AL1parameter.
When P13 = SPEC, it allows to select one of
the two values programmed by P14 and P15
parameters.
HSA3 Alarm 3 hysteresis This parameter is available
only if P 11 is equal to "AL3.P", "AL3.b" or
"AL3.d" and P13 = OPrt.
For other details see HSA1parameter.
Note: the alarm 2 and 3 are in OR condition on
the OUT 4.
