(Program time) – PROGRAM SEGMENTS TIME, 1 to 7:
Defines elapsed time in minutes of each segmento of the
program (see item 8).

Pe1

Pe7

(Program event) - EVENT ALARMS, 1 to 7:

Parameters

that define which alarms must be triggered while a program
segment is running, according to codes from 0 to 3
presented in Table 6. Alarm function depends on “rS

rS“

setting.

(Link to Program) - LINK TO PROGRAM: Number of the next
program to be connected. Programs can be linked to generate
profiles of up to 49 segments (see item 8.1).

0 – do not connect to any other program

1 – connect to program 1

2 – connect to program 2

3 – connect to program 3

4 – connect to program 4

5 – connect to program 5

6 – connect to program 6

7 – connect to program 7

(Hysteresis of Alarms) – ALARMS HYSTEREIS: Defines
the differential range between the PV value at which the
alarm is turned on and the value at which it is turned off.
One hysteresis value is set for each alarm.

A1t1

(Alarm 1 time 1) – ALARM 1 TIME 1: Defines the period, in
seconds, in which the alarm output will be on when alarm 1
is activated. Set zero to disable this function.

A1t2

(Alarm 1 time 2) – ALARM 1 TIME 2: Defines the period in
which alarm 1 will be off after being activated. Set zero to
disable this function.

A2t1

(Alarm 2 time 1) – ALARM 2 TIME 1: Defines the period, in
seconds, in which the alarm output will be on when alarm 2
is activated. Set zero to disable this function.

A2t2

(Alarm 1 time 2) – ALARM 2 TIME 2: Defines the period in
which alarm 2 will be off after being activated. Set zero to
disable this function. Table 4 shows the advanced functions
one can obtain with timer.

INPUT CONFIGURATION CYCLE

Type

(tYPE) – TYPE OF INPUT: Selection of the type of signal
connected to the PV input. See Table 1.

This must be the first parameter to be set up.

Dppo

(decimal Point Position) – DECIMAL POINT POSITION:
Only for inputs 16, 17, 18 and 19. Determines the position of
the decimal point in all parameters related to PV and SP.

vnI t

(unit) - TEMPERATURE: Selects the temperature unit:
Celsius (“°C“) or Fahrenheit (“°F

F“).Not valid for inputs 16, 17,

18 and 19.

Offs

(oFFSet) - OFFSET for PV: Offset value to be added to the
PV to compensate sensor error. Default value: zero.
Adjustable between -400 and +400.

Spll

(SetPoint Low Limit) - SETPOINT LOW LIMIT:
For linear inputs, selects the minimum value of indication
and adjustment for parameters related to PV and SP.

For thermocouples and Pt100, selects the minimum value for
SP adjustment.

Defines also the lower limit value for retransmission of PV
and SP.

Spxl

(SetPoint High Limit) – SETPOINT HIGHER LIMIT
For linear inputs, selects the maximum value of indication
and adjustment for parameters related to PV and SP. For
thermocouples and Pt100, selects the maximum value for
SP adjustment.
Defines also the higher limit value for retransmission of PV
and SP.

Pot

(Potentiometer) – Selects value that will be displayed in the
MV screen (the second screen of the main cycle).

YES

YES -

- Shows the potentiometer value

NO -

- Shows the PID output

Bavd

COMMUNICATION BAUD RATE Available with RS485.

0=1200 bps; 1=2400 bps; 2=4800 bps; 3=9600 bps;
4=19200 bps

Addr

(Address) - COMMUNICATION ADDRESS: With RS485,
number that identifies the controller in the communication
between 1 and 247.
