OPERATIVE PARAMETERS

The following is a list of all the available control

parameters.

Note that some parameters may not be displayed

depending on the specific instrument

configuration.

To modify the setting of a parameter proceed as

follows:

1) By means of the FUNC pushbutton select the

parameter to be modified.

2) Using the  and  keys set the value

required.

3) Press the FUNC pushbutton to save the new

value and go to the next parameter.

4) Press SMT to return to the previous parameter

without saving.

NOTESNOTES

NOTESNOTES

NOTES:

1) If, during parameter modification, no

pushbutton is pressed for more than 10

seconds, the instrument automatically reverts

to the “normal display mode” and the new

setting of the last parameter will be lost.

2) The instrument does not display all the possible

parameters, but only those which are in

agreement with:

a) The instrument configuration (see section 4).

b) The setting of parameter P14 (see section

4).

c) The setting of the proportional band (see

section 5.5).

Param. Description

SPSP

SPSP

SP Set point (in eng. units).

Span: from rL to rH.

n.rSn.rS

n.rSn.rS

n.rS Manual reset of the alarms.

This parameter is displayed if one alarm

has been programmed with manual reset.

Set ON and press the FUNC pusbutton

to reset the alarms.

SP2SP2

SP2SP2

SP2 Set point 2 (in eng. units).

This parameter is present if P22 = 1, 2, 3,

4 or 5.

Span: from rL to rH.

tt

tt

t time of the timer function (in minutes and

seconds).

This parameter is present if P22 greater

than 4.

Span: from 10 seconds (00.1) to 90

minutes (90.0).

nnnnnn

nnnnnn

nnn Software key for parameter protection.

This parameter is skipped if P11 = 0 or 1.

ON = the instrument is in LOCK

condition

OFF = the instrument is in UNLOCK

condition.

To switch from LOCK to UNLOCK, set a

value equal to the value of parameter

P11.

To switch from UNLOCK to LOCK, set a

value different from the value of parameter

P11.

Span: 2/999

AL.1AL.1

AL.1AL.1

AL.1 Alarm 1 threshold (in eng. units).

This parameter is available only if

P5 = 1, 2 or 3.

Spans:

- From P2 to P3 for process alarm

(P5 = 1)

- From 0 to 500 units for band alarm

(P5 = 2).

- From -199 to 500 units for deviation

alarm (P5 = 3).

HS.1HS.1

HS.1HS.1

HS.1 Alarm 1 hysteresis (in % of P3 - P2 span).

This parameter is available only if

P5 = 1, 2 or 3.

Span: From 0.1% to 10.0% of the input
