SET POINTS

This instrument allows to use 2 set points: SP and
SP2.
The set point selection is possible only by logic
input.

Set point transfer

:

The transfer between one set point to another (or
between two different set point values) may be
realized by a step transfer or by a ramp with two
different programmable rate of change (ramp up
and ramp down).

Slope value

: 1 - 100 eng. unit/min or step.

Set points limiter

: RLO and RHI parameters, pro-

grammable.

CONTROL ACTIONS

Control action

: PID + SMART

Type

: One (heating or cooling) or two (heating and

cooling) control outputs.

Proportional Band

(Pb):

Range: - from 1.0 to 100.0 % of the input span for

process with one control output.

- from 1.5 to 100.0 % of the input span for

process with two control outputs.

When Pb=0, the control action becomes ON/OFF.

Hysteresis

(for ON/OFF control action):

from 0.1% to 10.0% of the input span.

Integral time (Ti)

: from 1s to 20 min. or excluded.

Derivative time (Td)

: from 1 s to 10 min.

If zero value is selected, the derivative action is
excluded.

Integral pre-load

:

- from 0.0 to 100.0 % for one control output
- from -100.0 (cooling) to +100.0 % (heating) for
two control outputs.

SMART

: keyboard enabling/disabling

Auto/Manual

: selectable by front pushbutton.

Auto/Manual transfer

: bumpless method type

Indicator "MAN"

: OFF in auto mode and lit in

manual mode.

OUTPUTS

Type

: This instrument is equipped with 3

independent outputs programmable as follows:

Out 1

Out 2

Out 3

linear (mA)

Control output updating time

:

- 250 ms when a linear input is selected
- 500 ms when a TC or RTD input is selected.

Action

: direct/reverse programmable by front

keyboard.

Output level indication:

The instrument displays separately the output 1
level (heating) and the output 2 level (cooling).

Output status indication

: the OUT 1 LED will

flash with a duty cycle proportional to the output 1
power. Two indicators (OUT 2 and/or OUT 3) are
lit when the respective output is in ON condition.
