OPERATIVE SET POINT SELECTION

OPERATIVE SET POINT SELECTION OPERATIVE SET POINT SELECTION OPERATIVE SET POINT SELECTION 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.

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

SERIAL LINK

SERIAL LINK SERIAL LINK SERIAL LINK 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 NOTE NOTE: from serial link it is not possible to perform the
NOTE NOTE
"Feedback potentiometer calibration" as well as the action
performed by logic input 2 (Cnt 2).

(ON or OFF) of the selected parameter.
By or pushbutton it is possible to set the desired value

or the desired status.
SP2
Pushing the FUNC pushbutton, the instrument memorizes the
SP3
new value (or the new status) and goes to the next parameter.
SP4
Some of the following parameter may be skipped according
to the instrument configuration.
Param. DESCRIPTION
SP Set point Set point Set point (in eng. units). Set point Set point
Range: from rL to rH.
SP is operative when logic inputs 1 and 3 are
open.
Sñrt SMART status. SMART status SMART status SMART status 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. Manual reset of the alarms Manual reset of the alarms
Manual reset of the alarms 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 Set point 2 (in eng. units). Set point 2
Set point 2 Set point 2
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 Set point 3 (in eng. units). Set point 3 Set point 3 Set point 3
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 Set point 4 (in eng. units). Set point 4
Set point 4 Set point 4
Range: from rL to rH.
SP4 is operative when logic input 1 and the logic
input 3 are closed and P50 = 2.
