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

Set point (in eng. units).
Range: from rL to rH.
SP is operative when logic inputs 1 and 3 are
open.

Sñrt

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.

ñ.rSt

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 3 is open
while the logic input 1 is closed.
and P50 is different from 0.

SP3

Set point 3 (in eng. units).
Range: from rL to rH.
SP3 is operative when logic input 3 is closed
while the logic input 1 is open and P50 = 2

SP4

Set point 4 (in eng. units).
Range: from rL to rH.
SP4 is operative when logic input 1 and the logic
input 3 are closed and P50 = 2.

nnn

Software key for parameter protection.
This parameter is skipped if P18 = 0 or 1
On = the instrument is in LOCK condition
OFF = the instrument is in UNLOCK condition

OPERATIVE SET POINT SELECTION

It is possible to select the operating set point (SP, SP2,
SP3 or SP4) only by the binary conbination of the logic
inputs 1 and 3.

logic input 3

logic input 1

op. set point

open

SP2

open

SP3

SP4

By setting the P50 parameter it is possible to limit the
number of the available set points.

SERIAL LINK

The device can be connected to a host computer by a
serial link.
The host can put the device in LOCAL (functions and
parameters are controlled via keyboard) or in REMOTE
(functions and parameters are controlled via serial link)
mode.
The REMOTE status is signalled by a LED labelled REM.
This instrument allows to modify the operative and
configuration parameters, via serial link.
The necessary conditions to implement this function are
the following:
1) Serial parameters from SEr1 to SEr4 should be

properly configurated.

2) Device must be in the OPERATING mode

During the downloading of configuration the device
goes in open loop with all output in OFF state.

At the end of configuration procedure, the device performs
an automatic reset and then returns to close loop control.
NOTE: from serial link it is not possible to perform the
"Feedback potentiometer calibration" as well as the action
performed by logic input 2 (Cnt 2).
