CONFIGURATION CYCLE

type

INPUT TYPE: Selects the input signal type to be connected
to the process variable input. Refer to Table 1.

This is the first parameter to be set.

dppo

DECIMAL POINT POSITION: For input types 16, 17, 18 or
19 only. Selects the decimal point position to be viewed in
both PV and SV.

vnI

TEMPERATURE INDICATION IN ºC OR ºF: Selects the
display indication to be in ºC or ºF. Only available if input
type is other than 16, 17, 18 or 19.

offs

SENSOR OFFSET: Offset value to be added to the PV to
compensate sensor error. Default value: zero.

spll

SET POINT LOW LIMIT:

- Linear inputs: Sets the lower range for SV and PV
indication.

- T/C and Pt100 inputs: sets the lower range for SV.

spxl

SET POINT HIGH LIMIT:

- Linear inputs: Sets the upper range for SV and PV
indication.

- T/C and Pt100 inputs: sets the upper range for SV.

rsll

REMOTE SET POINT LOW LIMIT: Selects the lower range
for indication of the Remote Setpoint.

rsxl

REMOTE SET POINT HIGH LIMIT: Selects the upper
range for indication of the Remote Setpoint.

bavd

DIGITAL COMMUNICATON BAUD RATE SELECTION:
0: 1200 bps; 1: 2400 bps; 2: 4800 bps; 3: 9600 bps; 4:
19200 bps.

addr

SLAVE ADDRESS SELECTION: Identifies a slave in the
network. The possible address numbers are from 1 to 247.

I/O CYCLE (INPUTS AND OUTPUTS)

Io 1

o 1

I/O 1 FUNCTION: Selects the I/O function to be used at I/O
1 (relay 1). Options 0 to 5 are possible for this output. It is
normally used as option 5, PWM main control output. Refer
to Table 2 for functions.

Io 2

o 2

I/O 2 FUNCTION: Selects the I/O function to be used at I/O
2 (relay 2). Options 0 to 5 are available. This output is
normally used as alarm output. See Table 2 for functions.

Io 3

o 3

I/O 3 FUNCTION: Selects the I/O function to be used at I/O
3 (option 1). I/O 3 can be a relay output or a digital
input/output. Functions 0 to 10 are available. Refer to
Table 2 for functions. The presence of this I/O option is
detected by the controller and the prompt menu will only be
shown if the expansion option is available.

Io 4

o 4

I/O 4 FUNCTION: Selects the I/O function to be used at I/O
4 (option 2). I/O 4 can be a digital input/output. Functions 0
to 10 are available. Refer to Table 2 for functions. The
prompt menu will only be shown if the expansion option is
present.

Io 5

o 5

I/O 5 FUNCTION: Selects the I/O function to be used at I/O
5 (Analog Output). Functions 0 to 15 are available (See
Table 2). This option is normally used for main control
output or PV analog retransmission.

CALIBRATION CYCLE

All input and output types are factory calibrated. This cycle should
only be accessed by experienced personnel. If in doubt do not press
the

keys in this cycle.

Inl(

INPUT LOW CALIBRATION: Sets the Process Variable low
calibration (offset). Several keystrokes at

might

be necessary to increment one digit.

Inx(

INPUT HIGH CALIBRATION: Sets the Process Variable
span calibration (gain).

ovll

OUTPUT LOW CALIBRATION: Sets the analog current
output low calibration (offset).

Ovx(

OUTPUT HIGH CALIBRATION: Sets the analog current
output span calibration (gain).

(j l

COLD JUNCTION OFFSET CALIBRATION: Sets the cold
junction offset calibration.

xtyp

HARDWARE TYPE: Configures the controller to recognize
the actual installed optional hardware (accessories). The
parameters menu will show the parameters relative to the
optional hardware:

0 - no optionals or c/ RS485 only;

1 - relay 3 (I/O 3);

2 - Digital I/O (2 inputs/outputs: I/O3 and I/O4);

3 - Heater break protection (option);

Rsl(

REMOTE SET POINT LOW CALIBRATION: Sets the
Remote Set Point low calibration (offset). Several
keystrokes at

might be necessary to increment

one digit.

Rsx(

REMOTE SET POINT HIGH CALIBRATION: Sets the
Remote Set Point span calibration (gain).

RAMP AND SOAK PROFILE PROGRAM

Seven ramp and soak profiles with up to 7 segments each can be
programmed. Longer profiles of up to 49 segments can be created by
linking 2 or more profiles.

Figure 11 - Example of a complete ramp and

soak profile

Figure 12 - Example of a profile with
fewer segments. (T4 is set 0)

To execute a profile with fewer segments just program 0 (zero) for the
time intervals that follow the last segment to be executed.

The program tolerance “Ptol

Ptol

Ptol” defines the maximum deviation

between PV and SV for the execution of the profile. If this deviation is
exceeded, the program will be interrupted until the deviation falls to
within the tolerance band.

Programming 0 (zero) at this prompt disables the tolerance and the
profile execution will not to be halted even if PV does not follow SV
(time priority as opposed to SV priority).

LINK OF PROGRAMS

It is possible to create a more complex program, with up to 49
segments, joining the seven programs. This way, at the end of a
program execution the controller immediately starts to run another one.

When a program is created, it must be defined in the “LP

LP" screen

whether there will be or not another program.

To make the controller run a given program or many programs
continuously, it is only necessary to link a program to itself or the last
program to the first.
