rang in order tu assure the 1% display resolution.

NOTES:

1) Before connecting the instrument to the power line, make
sure that line voltage and the load current are in accord­ance with the contact rating (3A/250V AC on resistive
load).

2) To avoid electric shock, connect power line at the end of
the wiring procedure.

3) For servomotor connections use No 16 AWG or larger
wires rated for at last 75 °C.

4) Use copper conductors only.

5) Don’t run input wires together with power cables.

6) For feedback potentiometer, use shielded cable with the
shield connected to the earth at one point only.

7) The relay outputs are protected by varistor against
inductive load with inductive component up to 0.5 A.

INDUCTIVE LOADS

High voltage transients may occur when switching
inductive loads.
Through the internal contacts these transients may
introduce disturbances which can affect the performance
of the instrument.
The internal protection (varistor) assures a correct protection
up to 0.5 A of inductive component.
The same problem may occur when a switch is used in
series with the internal contacts as shown in Fig. 8.

Fig. 7 RELAY OUTPUTS WIRING

NOTE: OUT 1 can be used either as servomotor output or

as time proportional relay output; by the P5
parameter (see pag.11) it is possible to set the
desired output.

All relay outputs are protected by varistor against inductive
load with inductive component up to 0.5 A.
The contact rating of OUT 1 is 3A/250V AC on resistive
load, the contact rating of OUT 3 and 4 is 2A/250V AC on
resistive load.
The contact rating of the OUT 3 and 4 is 2A/250V AC resistive
load.
The number of operations is 1 x 105 at specified rating.
Alarm 2 and alarm 3 are in OR condition on the out 4.
The following recommendations avoid serious problems
which may occur, when using relay output for driving
inductive loads.

INSTRUMENT CONFIGURATION

1) Switch on the instrument.
The upper display shows the measured value while the
lower display shows the programmed set point value (we
define the above condition as “normal display mode”).

2) Push "FUNC" pushbutton and, maintaining the
pressure, push the "MAN" pushbutton for more than 4
seconds.
The lower display will show "ConF" while the upper
display will show "C.ñOn".
NOTE: two different configuration mode are possible:
A) Monitor mode: in this mode it is possible to

monitor but not to modify the configuration
parameter. During the monitor mode the instrument
continue to perform the standard control.

B) Modify mode: in this mode it is possible to verify

and to modify all configuration parameter.

3) By s and t pushbuttons select the "C.ñOd" indication
(modify mode).

4) Push the "FUNC" pushbutton.

NOTES:

1) When modify mode is started, the instrument stops the
control action and:

- sets control outputs to OFF;

- sets alarms in no alarm condition;

- disables the serial link.

2) If the configuration is protected by security code the
display will show:

By s and t keys enter a value equal to the
configuration security code (see P55 parameter) or the
master key code (see appendix A).
Note: the master key code allows to enter in modify
configuration parameters mode either if the configuration
security code is lost or if the configuration parameters are
always protected (P55 = 1).

FEEDBACK POTENTIOMETER LIMITS
SETTING

NOTE: this function is available only if the manual mode is

enabled (P38 = On) and a closed loop servomotor control
(P5 = "Sñ.CL")or a servomotor control open loop with
feedback indication (P5="Sñ.OL" and P6 = "Fb.")has been
selected during configuration procedure.
When it is desired to calibrate the feedback potentiometer,
proceed as follow:

1) Connect the specific servomotor to the instrument.

2) Switch On the instrument.

3) Push the MAN pushbutton for more than 1 s.
The instrument will go in MANUAL mode and the MAN
indicator will lit.

4) Keep pushing the FUNC pushbutton until the "F.CAL"
parameter is shown on the lower display.

5) Pushing s or t select the "ON" indication and then
push the FUNC pushbutton.
The instrument will show on the upper display the
actual valve position in percent and, on the lower
display the "POS.L" message.

6) Pushing continuously s or t pushbutton, drive the
servomotor to the beginning of its stroke.

7) Push the FUNC pushbutton.
The display will show "Fb.LC" (feedback low limit
calibration).

8) Pushing s or t select the "ON" indication and push
the FUNC pushbutton.
The instrument will show on the upper display the actual
valve position in percent and, on the lower display the
"POS.H" message.

9) Pushing continuously s or t pushbutton, drive the
servomotor to the end of its stroke.

10) Push the FUNC pushbutton.
The display will show "Fb.HC" (feedback high limit
calibration).

11)Pushing s or t select the "ON" indication and push
the FUNC pushbutton.
The instrument memorizes the new feedback
potentiometer calibration and return in MANUAL mode.

NOTES:

1) The minimum span (Fb.LC - FbHC) acceptable for the
instrument is equal to 20 % of the potentiometer
stroke.

17

XKSser1-A0.p65 10/19/01, 1:37 PM17

2) The instrument is able to assure a 1% resolution for
the potentiometer indication only if the calibrated span
is greater than 50 % of the potentiometer stroke.

ENABLE/DISABLE THE CONTROL OUTPUT

NOTE: this function is available only when OUT 1 is

programmed as proportional control putput.
When the instrument is in "normal display mode", by keeping
depressed for more than 5 s s and FUNC pushbuttons, it is
possible to disable the control outputs. In this open loop
mode the device will function as an indicator, the lower
display will show the word OFF and all control outputs will be
in the OFF state.
When the control outputs are disabled the alarms are also
in non alarm condition.
The alarms output conditions depend on the alarm action
type (see P26-P28).
Depress for more than 5 s s and FUNC pushbuttons to
restore the control status.
The alarm standby function, if configured, will be activated
as per power up.
If a shut down occures when the control output is
disabled, at instrument power up the control output will be
disabled again.

DIRECT ACCESS TO SETPOINT

When the device is in AUTO mode and in “Normal Display
Mode”, it is possible to modify directly the selected set
point (SP, SP2, SP3 or SP4).
Pushing s or t for more than 2 s, the setpoint will begin
changing.
The new setpoint value becomes operative since no
pushbutton has been depressed at the end of 2 s
timeout.

MANUAL FUNCTION

The MANUAL mode function can be accessed (only if
enabled by P38=On) by depressing the MAN pushbutton for
more than 1 sec or by closing the external contact 2 (see P24
parameter).
The command from keyboard is accepted and executed
only if the display is in "Normal Display Mode".
The command from external contact is always accepted.
When in MANUAL mode the LED's MAN annunciator will
light up while the lower display shows the valve position (if
configured) or power output values if time proportioning
control output is configured.
When time proportioning control output is configured, the
power of the "rEv" output is shown in the two most
significant digit field while the power of the "dir" output (if
present) is shown in the two less significant digit field.
The decimal point between the two values will be flashing
to indicate instrument in MANUAL mode.
Note: The instrument shows the "rEv" output = 100 with

the graphic simbol " ".
The instrument shows the "dir" output = 100 with the
graphic simbol " ".

The power output can be modified by using s and t
pushbuttons.
By depressing, for more than 1 second, MAN again, or by
opening the contact 2, the device returns in AUTO mode.
The transfer from AUTO to MANUAL will be in accordance
with P40 parameter set.
The transfer from MANUAL to AUTO will be bumpless
(this function is not provided if integral action is excluded).
If transfer from AUTO to MANUAL is performed during the
first part of SMART algorithm (TUNE) when returning in
AUTO the device will be forced automatically to the
second part of the SMART algorithm (ADAPTIVE).
At power up the device will start as selected with P39.
Notes:

1) When device is configured for two control outputs and
start up occurs in Manual mode with power output set
to 0, the signal output will be in accordance with the
following formula: "rEv" output - "dir" output = 0.

2) When the AUTO/MANUAL control is selectable by
logic input and P39 = 0 or 1, the instrument starts in
accordance to the logic input status and ,for MANUAL
mode, it will start with a power output equal to zero.

"LOOP BREAK ALARM" FUNCTION

The functioning principle of this alarm is based on the
concept that, with a steady load and steady power output,
the process rate of rise [deviation (P52)/time (P53)] is
steady as well.
Thus, analyzing the process rate of rise of the limit
conditions it is possible to estimate the two rates of rise
which define the correct process behaviour.
The limit conditions are:
3 for one control output: 0% and the value of the "OLH"

parameter or

3 for two control outputs: -100% and the value of the

"OLH" parameter,
The LBA function is automatically activated when the
control algorithm requires the maximum or the minimum
power and, if the process response is slower than the
estimated rate of rise, the instrument generates an alarm
indication in order to show that one or more element of the
control loop is in fault condition.

Deviation: from 0 to 500 units.
Timer: from 1 sec. to 40 min.
Hysteresis: from 1% to 50 % of the output span.
NOTES:

1) The LBA does not operate during the soft start.

2) For this special function the hysteresis is related with

the power output value and not with its rate of rise.

SMART function

It is used to optimize automatically the control action.
At instrument power up, if the SMART is ON, the second
algorithm will be enabled.
To enable the SMART function, push the FUNC
pushbutton until "Snrt" parameter is shown.
Pushing s or t set the display "On" and push the
FUNC pushbutton.
The SMRT LED will turn on or flashing according to the
selected algorithm.
When the smart function is enabled, it is possible to
display but not to modify the control parameters (Pb, ti, td,
and rC).
To disable the SMART function, push the FUNC
pushbutton again until "Snrt" parameter is shown.
Pushing s or t set the display "OFF" and push the
FUNC pushbutton. The SMRT LED will turn off.
The instrument will maintain the actual set of control
parameter and will enabled parameter modification.

NOTES: 1) When ON/OFF control is programmed

LAMP TEST

When it is desired to verify the display efficiency, push
FUNC pushbutton for more than 10 s. The instrument will
turn ON, with a 50 % duty cycle, all the LEDs of the
display (we define this function "LAMP TEST").
No time out is applied to the LAMP TEST.
When it is desired to come back to the normal display
mode, push FUNC pushbutton again.
During the LAMP TEST the instrument continues to
control the process but no keyboard functions are
available (exception made for the FUNC pushbutton).

(Pb=0), the SMART function is disabled.

2) The SMART enabling/disabling can be
protected by safety key (see P33).

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).
