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 configuration parameters.

= (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 time out will be removed.

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 master key
(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 (P51 = 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.

range.

Notes:

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

2) If a linear input is selected, the value of this parameter
can be greater than P4 in order to get a reverse
readout.

P4 = Full scale value

For linear inputs it is programmable from -1999 to 4000.
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.

RUN TIME MODE

DISPLAY FUNCTIONS

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”).
Note: When the rate of change (Grd1, Grd2) is utilized,

the displayed set point value may be different

from the operating set point.
It is possible to change the information on the lower
display as follows:

- Push the FUNC pushbutton for more than 3 s but less

than 10 s. The lower display will show "A." followed by
the current consumed by the load (driven by the OUT

1) when the load is in ON condition (see also "OUT 1
failure detection").

- Push "FUNC" pushbutton again. The lower display will

show "b." followed by the leakage current running in
the load (driven by the OUT 1) when the load is in OFF
condition (see also "OUT 1 failure detection").

- Push "FUNC" pushbutton again. The lower display will

show "H." followed by OUT 1 power value (from 0 to
100%).

- Push FUNC pushbutton again. The lower display will

show "C." followed by OUT 2 power value (from 0 to
100%).

- Push FUNC pushbutton again. The display will return

in "Normal Display Mode".
NOTE: The "A.", "b" and "C." informations will be
displayed only if the relative function has been previously
configured.

When no pushbutton is pressed during the time out (see
P39), the display will automatically return in "Normal
Display Mode".
In order to keep continuously the desired information on

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

parameters.

ENABLE/DISABLE THE CONTROL OUTPUT

When the instrument is in "normal display mode", by
keeping depressed for more than 5 s the 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 P21-P23-P25).
Depress for more than 5 s the s and FUNC pushbuttons
to restore the control status.
The alarm stand-by function, if configured, will be
activated as per power up.
If a shut down occurs when the control output is disabled,
at instrument power up the control output will be disabled
again.

MANUAL FUNCTION

It is possible to enter in MANUAL mode (only if enabled by
P30=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 MAN lights up while the
lower display shows the power output values.
The value of OUT 1 is shown by the two most significant
digits while the value of OUT 2 (if present) is shown by the
two less significant digits.
The decimal point between the two values will be flashing
to indicate instrument in MANUAL mode.
Note:

- The graphic symbol " " is used for OUT1 = 100 %

- The graphic symbol " " is used for OUT2 = 100 %
The power output can be modified by using s and t

pushbuttons.
By depressing, for more than 2 seconds, MAN pushbutton
again the device returns in AUTO mode.

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 AUTO mode or as it
was left prior to power shut down depending on P37
configuration selection.
Note: When start up occurs in Manual mode the power

output (OUT1 - OUT2) is set to 0.

OUT 1 FAILURE DETECTION FUNCTION

The device is capable (for the load driven by the OUT 1)
to measure and display:

- the current running in the load when the load is
energized

- the leakage current, flowing through the load, when the
load is de-energized.

If the P10 parameter has been correctly set, the
instrument generates an alarm when:

- the current running in the load is lower than the "Hbd"
parameter value (It shows a partial or total break down
of the load, the break down of the actuator or a power
down due to a protection or a fuse intervention);

- the leakage current is higher than the "SCA" parameter
value (It shows a short circuit of the actuator).

The "Display function" paragraph describes how to show
the two current values.
A fault condition is shown by OUT 3 LED flashing and by
OUT 3 relay status.
If the ON or OFF period is lower than 400 ms the relative
measurement couldn't be performed and the instrument
will show flashing the last measured value.

"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 (P48)/time (P49)] 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) If the instrument operates with the SMART function, the

LBA may be operating.

3) For this special function the hysteresis is related with

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

SP/SP2 SELECTION

It is possible to select the operating set point (SP or SP2) only
by a logic input (terminals 7 and 8).
By setting P45, it is possible to display the final or the
operative set point during a ramp execution.

31080-1-00.p65 3/24/00, 11:58 AM18

18

DIRECT ACCESS TO SET POINT

When the device is in AUTO mode and in “Normal Display
Mode”, it is possible to access directly to set point
modification (SP or SP2).
Pushing s or t for more than 2 s, the set point will begin
changing.
The new setpoint value becomes operative since no
pushbutton has been depressed at the end of 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)
mode.
The REMOTE status is signalled by a LED labelled REM.
This instrument allows to modify the run time 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 configured.

2) Device must be in the RUN TIME 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.
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 "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 (Pb, ti, td,
and rC).
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 current set of control
parameter and will enabled parameter modification.
NOTES:

1) When ON/OFF control is programmed (Pb=0), the
SMART function is disabled.

2) The SMART enabling/disabling can be protected by
safety key (see P31).

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 FUNC pushbutton).

the code while the upper display will show 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

ERROR MESSAGES

OVERRANGE, UNDERRANGE AND SENSOR LEADS
BREAK INDICATIONS

The device is capable to detect a fault on the process
variable (OVERRANGE or UNDERRANGE or SENSOR
LEADS BREAK).
When the process variable exceeds the span limits
established by configuration parameter P 1 an
OVERRANGE condition will be shown on the upper
display as in the following figure:

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

When P41 is different from zero and an out of range
condition is detected, the instrument operates in
accordance with P41 and P42 parameters.

When P41 is equal to 0 the following conditions may
occur:

- The instrument is set for one output only and an
OVERRANGE is detected, the OUT 1 is forced to 0 (if
reverse action) or to 100 % (if direct action).

- The instrument is set for heating/cooling action and an
OVERRANGE is detected, OUT 1 is forced to 0 and
OUT 2 is forced to 100 %.

- The instrument is set for one output only and an
UNDERRANGE is detected, the OUT 1 is forced to
100 % (if reverse action) or to 0 (if direct action).

- The instrument is set for heating/cooling action and an
UNDERRANGE is detected, OUT 1 is forced to 100 %
and OUT 2 is forced to 0.

The sensor leads break can be signalled as:

- for TC/mV input : OVERRANGE or UNDERRANGE

- for RTD input : OVERRANGE

- for mA/V input : UNDERRANGE
Note: On the mA/V input the leads break can be detected

only when the range selected has a zero elevation (4/20
mA or 1/5 V or 2/10 V)
On RTD input a special test is provided to signal
OVERRANGE when input resistance is less than 15 ohm
(Short circuit sensor detection).

ERROR MESSAGES

The instrument performs some self-diagnostic tests.
When an error is detected, the instrument shows on the
lower display the “Err” indication, while the upper display
shows the code of the detected error.

ERROR LIST

less significant digits show the number of
the wrong parameter (ex. 209 Err shows
an Error on P9 parameter).

NOTES:

1) When a configuration parameter error is detected, it is

sufficient to repeat the configuration procedure of the
specific parameter.

2) If error 400 is detected, push contemporarily the t

and s pushbuttons for loading the default parameters
then repeat run time parameter setting.

3) For all the other errors, contact your supplier.
