6 CONFIGURATION PROCEDURE

6.1 Introduction

When the instrument is switched ON, it starts immediately working
in accordance with the parameters values loaded in memory.
The instrument behaviour and its performance are governed
by the value of the stored parameters.
At the first start up the instrument will use a “default” param-
eter set (factory parameter set); this set is a generic one
(e.g. a TC Pt100 input is programmed).

Before connecting the output actuators

we recommend to configure the parameters to suit your
application (e.g.: input type, Control strategy, alarms, etc.).

Do not change the

[6] Unit (Engineering Unit)

value

during process control as the temperature values
inserted by the user (thresholds, limits etc.) are not
automatically rescaled by the instrument.

To change these parameters you need to enter the
“

Configuration mode

”.

6.2 Instrument description

This instrument is a special version derived from our standard
KUBE line and dedicated to the specific needs of wine making
and oenology markets with the following features:

–

Temperature ON/OFF control with hysteresis, Heating (set
point SP) or Cooling (set point SP2);

–

Highly readable display whose color indicates if control is
in Heating (Red) or Cooling (Green) mode selected, for a
safe control.

Suitable for the following control modes:

–

One circuit control (Out1 relay for Heating and Cooling –
see [1] node = 1 at page 6);

–

2 circuits control (Out1 relay for Heating and Out2 relay for
Cooling – see [1] node = 2 at page 6) with manual selec-
tion Heating or Cooling;

–

2 circuits control (Out1 relay for Heating and Out2 relay for
Cooling – see [1] node = 3 at page 6) with automatic Heat-
ing and Cooling action;

–

Select Heating or Cooling manually by dedicated front button,
or digital input, or serial communication, or automatically;

–

Select Control run (Auto) or stop (Stand-By) manually by dedi-
cated front button, or digital input, or serial communication;

–

Alarms low (AL1) and high (AL2) and sensor break detec-
tion with relay output Out3;

–

Temperature sensor break detection with manual forcing of
control output;

–

Easy to configure for the installer (wine market preconfig-
ure), easy to use for the operator (dedicated front buttons);

–

Controller and/or software configuration backup using the
key (

A01

) through the serial port;

–

3 separated menus: operator (free access), limited access
(protected), configuration (protected).

With its high standard of adaptability this instrument is able
to cover all wine market needs at highest reliability level.

6.3 Instrument behaviour at Power ON

At power ON the instrument can start in one of the following
mode depending on its configuration:

Auto mode

–

The upper display shows the measured value;

–

The lower display shows the Set point value;

–

The decimal figure of the less significant digit of the lower
display is OFF;

–

The instrument is performing the standard closed loop control.

Standby mode

(

St.bY

–

The upper display shows the measured value;

–

The lower display shows alternately the set point value and
the message

St.bY

;

–

The instrument does not perform any control (the control
outputs are OFF);

–

The instrument is working as an indicator.

We define all the above described conditions as “

Standard

display

”.

Entering the “Configuration modes”

6.4.1 Complete configuration procedure

The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).

Push the

button for more than 5 seconds. The upper

display will show

PASS

while the lower display shows

Using

and

buttons set the programmed password.

Notes: 1.

The factory default password for configuration
parameters is equal to

During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration change
can produce a heavy bump to the process, it is
advisable to temporarily stop the controller from
controlling during the programming procedure
(control output will be OFF).
A password equal to

2000 + the programmed

value

(e.g. 2000 + 30 = 2030).

The control will restart automatically when the
configuration procedure will be manually closed.

Push the

button

If the password is correct the display shows the acronym of
the first parameter group preceded by the symbol:

In other words the upper display shows:
