OPERATIVE PARAMETERS

Push the FUNC pushbutton, the lower display will
show the code while the upper display will shows
the value or the status (ON or OFF) of the selected
parameter.
By s or t pushbutton it is possible to set the
desired value or the desired status.
Pushing the FUNC pushbutton, the instrument
memorizes the new value (or the new status) and
goes to the next parameter.
Some of the following parameter may be skipped
according to the instrument configuration.
Param. DESCRIPTION
SP
Set point (in eng. units).
Range: from rL to rH.
SP is operative when logic inputs 1 and 3
are open.
SMRT
SMART status.
The On or OFF indication shows the
actual status of the SMART function
(enabled or disabled respectively).
Set On to enable the SMART function.
Set OFF to disable the SMART function.
M. R ST
Manual reset of the alarms.
This parameter is skipped if none of the
alarms have the manual reset function.
Set On and push FUNC to reset the alarms.
SP2
Set point 2 (in eng. units).
Range: from rL to rH.
SP2 is operative when logic input 1 is
closed and P50 is equal to 1.
LFS-servo-1-02.p65 24
NNN
Software key for parameter protec-
tion.
This parameter is skipped if P18 = 0 or 1
ON = the instrument is in LOCK condition
OFF = the instrument is in UNLOCK condi-
tion
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.
HSA. 1
Alarm 1 hysteresis
This parameter is available only if P 7 is
equal to "AL1. P ", "AL1. B " or "AL1. D ".
Range (in engineering units): from 1 to
the lower value between 250 units and
the programmed span (P4 - P3).
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 HSA. 1 parameter.
