ovkl
Output High

Upper limit for the control output - Maximum
percentage for the control output when in
automatic mode and in PID. Typically configured
with
100 %
. Default value: 100 %
sfst
Softstart
SoftStart
Function –
:
Time in seconds during which
the controller limits the MV value progressively
from 0 to 100 %. It is enabled at power up or when
the control output is activated. If in doubt set zero
(zero value disables the Soft start function).
Sp.a1
Sp.a2
Sp.a3
Sp.a4
ALARM SETPOINT: Tripping point for alarm 1, 2, 3
and 4. Value that defines the point of activation for
the programmed alarms with the functions “
Lo
” or
“
ki
”.
For the alarms configured with
Differential
type
functions, this parameter defines deviation (band).
Not used for the other alarm functions.
CYCLE OF PROGRAMS
Pr.tb
Program time
base
Defines the time base that will be used by all Ramp
& Soak programs.
Se(
- Time basis in seconds;
Min
- Time basis in minutes;
Pr n
Program
number
Selects the ramp and soak profile program to be
edited/viewed. The sequence of parameters that
follows refer to this selected program. Total of 20
programs possible.
Ptol
Program
Tolerance
Maximum admitted deviation of PV with respect to
SP. If exceeded, the program execution is suspended
(the internal timer freezes) until the deviation be
returns back within the defined tolerance.
The value 0 (zero) disables the function (the
program progresses regardless of the difference
between PV and SP).
Psp0
Psp9
Program SP’s, 0 to 9: Group of 10 values of SP that
define the Ramp and Soak profile segments.
Pt1
Pt9
Segments durations, 1 to 9: Defines the time of
duration, in second or minutes, of the segments of
the program being edited.
Pe1
Pe9
Program event
Alarms of Event, 1 to 9: Parameters that define
which alarms are to be activated during the
execution of a certain program segment. The alarms
chosen must have its function configured as “
rS
.”
(See
Table 3
)
Lp
Link Program
Link Programs: Number of the next profile program
to be linked following the current program. Profiles
can be linked together to produce larger programs
of up to 180 segments
.
0
– do not link to any other program.
CYCLE OF ALARMS:
Fva1
Fva2
Fva3
Fva4
FUNCTIONS OF ALARMS 1 to 4. Defines the
functions for the alarms among the options of the
Table 3
.
bla1
bla2
bla3
bla4
BLOCK ALARM 1 TO 4: This function blocks the
alarms when the controller is energized.
YES
- enables initial blocking
NO
- inhibits initial blocking
When enabled, the alarm will not be active at
power-up, waiting for PV (Process Variable) to
reach a non-alarm situation. From this point on the
alarm will be free to actuate should a new alarm
situation occur.
xya1
ALARM HYSTERESIS
:
Defines the difference
between the value of PV at which the alarm is
xya2
xya3
xya4
triggered and the value at which it is turned off (in
engineering units).
A1t1
A2t1
A3t1
A4t1
Alarm Time
t1
Defines the temporization time
t1
, in seconds, for
the alarms. Defines the temporization time
t1
, in
seconds, for the alarms time functions. The value 0
(zero) disables the function.
Refer to
Table 4
for configuring this parameter
timed functions. The value 0 (zero) disables the
function.
Refer to
Table 4
for configuring this parameter.
A1t2
A2t2
A3t2
A4t2
Alarm Time
t2.
Defines the temporization time
t2
,
in seconds, for the alarms time functions. The
value 0 (zero) disables the function. Refer to
Table
4
for configuring this parameter
flsh
Flash
Allows visual signalization of an alarm occurrence
by flashing the indication of PV in the operation
level. The user chooses which alarms are to be
associated with this feature.
CYCLE OF SCALE
Type
Type
INPUT TYPE: Selects the input signal type to be
connected to the process variable input. Refer to
Table 1
for the available options.
fltr
Filter
Digital Input Filter - Used to improve the stability of
the measured signal (PV). Adjustable between 0
and 20. In 0 (zero) it means filter turned off and 20
means maximum filter. The higher the filter value,
the slower is the response of the measured value.
Dppo
Decimal Point
Selects the decimal point position to be viewed in
both PV and SP
.
vnI t
Unit.
Temperature indication in ºC or ºF:
root
Square Root
Square Root Function. Applies the quadratic
function on the input signal, within the limits
programmed in “
SPLl
” and “
spkL
.”
YES
Enables the Function
no
Does not enable the Function
The indication assumes the lower limit value when
the input signal is below 1 % of programmed span.
Parameter available for lineal inputs only.
0ffs
Offset
SENSOR OFFSET: Offset value to be added to
the PV reading to compensate sensor error.
Default value: zero.
e.rsp
Enable Remote
SP
Enables remote SP.
YES
Enables the Function
no
Does not enable the Function
This parameter is not displayed when the remote
SP selection is defined by a Digital Input.
rsp
Remote SP
type
Defines the signal type for the remote SP.
0-20
current of 0-20 mA
4-20
current of 4-20 mA
0-5

0-10
voltage of 0-10 V
Parameter displayed when remote SP is enabled.
rsll
Remote SP
Low Limit
REMOTE SETPOINT LOW LIMIT: used in
conjunction with the
rSxL
, scales the remote SP
input defining the initial value in the remote SP
indication range.
Parameter displayed when remote SP is enabled.
