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

INSTRUMENT CONFIGURATION

Run time and configuration modes

When the instrument is in run time mode and no
modification parameter is in progress, the measured
variable is shown on the upper display, while the set point
is shown on the lower display (we define this condition
"normal display mode").

General note about graphic symbols used for
mnemonic code visualization.

The instrument displays some characters with special
symbols.
The following table shows the correspondence between
the symbols and the characters.

CONFIGURATION PROCEDURE

At power up, the instrument starts in the same mode
(configuration or run time) it was prior to the power OFF.

When it is desired to go from run-time mode to
configuration mode proceed as follows:
a) keep depressed the FUNC pusbutton and push the

symbol character

pushbuttons for more than 4 seconds, the upper
display will show:

The same indication will be shown when the instrument
starts in configuration mode.

b) By the s or t key it is possible to select between:

= (monitor) this selection allows to monitor

but not to modify the value of all
configurationparameters.

= (modify) this selection allows to monitor

and to modify the value of all
c) Push the FUNC pushbutton.
NOTES:

1) During monitor mode, the instrument continues to

operate as in run time mode and if no push-button is
depressed for more than 10 s (or 30 s according to
P39 [time out selection"]), the instrument returns
automatically to the normal display mode.

2) When modify mode is started, the instrument stops the

control and:

- sets control outputs to OFF;

- sets alarms in no alarm condition;

- disables the serial link;

- the linear output is forced to 0 (also for 4-20 mA
output)

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

By s and t keys enter a value equal to the security
code set for the configuration mode or the passe­partout code (see appendix A.3).
Note: the master key allows to enter in modify
configuration parameters mode either if any other
configuration security code is set or if the configuration
parameters are always protected (P55 = 1).

When it is desired to exit from configuration modify mode
proceed as follows:
a) Push "FUNC" or "MAN" push-button more times until

the "C.End" parameter is displayed.

b) Pushing ”s” or “t” push-button select the "YES"

indication.

For TC and RTD inputs, it is programmable within the
input range.

Notes:

1) When this parameter is modified, rH parameter will be
re-aligned to it.

2) If a linear input is selected, the value of this parameter
can be smaller than P3 in order to get a reverse
readout.

The initial and full scale values determine the input span
which is used by the PID algorithm, the SMART and the
alarm functions.

NOTE: the minimum input span (S = P4 - P3), in absolute
value, should be set as follows:

- For linear inputs, S > 100 units.

- For TC input with °C readout, S > 300 °C.

- For TC input with °F readout, S > 550 °F.

- For RTD input with °C readout, S > 100 °C.

U. followed by the firmware version.

Push FUNC pushbutton again. The display will return

in "Normal Display Mode".
NOTE: The information will be displayed only if the relative
function has been previously configured.
When no pushbutton is pressed during the time out (see
P41), the display will automatically return in "Normal
Display Mode".
In order to keep the desired information continuously on

the lower display, depress s or t pushbuttons to
remove the timeout.
When is desired to return in "Normal Display Mode" push
FUNC pushbutton again.

ENABLE/DISABLE THE CONTROL OUTPUTS

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
also be in the OFF state (the real output is conditioned by P21
and P23 parameter also).
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 P27-P29-P31).
Depress for more than 5 s s and FUNC pushbuttons to
restore the control status.
The alarm standby function, if configured, will be
activated.
The enabling/disabling status will not be lost at power
down.

MANUAL FUNCTION

The MANUAL mode function can be accessed (only if
enabled by P39=On) by depressing the MAN pushbutton
for more than 1 sec.
The command is accepted and executed only if the
display is in "Normal Display Mode".
When in MANUAL mode the LED's MAN annunciator will
light up while the lower display shows the power output
values.
The value of "rEv" output is shown in the two most significant
digit field while the value of "dir" output 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:

A graphic simbol " " is used for "rEv" out = 100
A graphic simbol " " is used for "dir" out = 100

When the instrument is in manual mode the output
resolution is equal to 1 %.
The power output can be modified by using s and t
pushbuttons.
By depressing, for more than 1 seconds, MAN again the
device returns in AUTO mode.

31081-1-00.p65 3/24/00, 11:59 AM19

19

The transfer from AUTO to MANUAL and viceversa is
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 be in the status defined by P40
parameter.
Note: When start up occurs in Manual mode with power

output set to 0, the control outputs will be in
accordance with the following formula: "rEV"
output - "dir" output = 0

DIRECT ACCESS TO SETPOINT

When the device is in AUTO mode and in “Normal Display
Mode”, it is possible to access directly to setpoint
modification (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 a 2 s
timeout.

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).
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 using the standard front
keyboard procedure

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.

SMART function

It is used to optimize automatically the control action.
To enable the SMART function, push the FUNC
pushbutton until "Sñrt" 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.
To disable the SMART function, push the FUNC
pushbutton again until "Sñrt" 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) The SMART function is disabled when:

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 function is available
(exception made for the FUNC pushbutton).

a) ON/OFF control is programmed
b) the instrument is in manual mode
c) P35 is equal to zero.

2) The SMART enabling/disabling can be pro­tected by safety key. (see P35)

31081-1-00.p65 3/24/00, 11:59 AM20

"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.

OPERATIVE PARAMETERS

established by configuration parameter P 1 an
OVERRANGE condition will be shown on display as show
in the following figure:

An UNDERRANGE condition will be shown on display as
shown in the following figure:

When P42 is equal to 0, the following conditions may
occur:

- The instrument is set for one output only and an
OVERRANGE is detected, the OUT turns OFF (if
reverse action) or ON (if direct action).

- The instrument is set for heating/cooling action and an
OVERRANGE is detected, OUT "rEV" turns OFF and
OUT "dir" turns ON.

- The instrument is set for one output only and an
UNDERRANGE is detected, the OUT turns ON (if
reverse action) or OFF (if direct action).

- The instrument is set for heating/cooling action and an
UNDERRANGE is detected, OUT "rEV" turns ON and
OUT "dir" turns OFF.
