6. CONFIGURATION PROCEDURE
6.1 Introduction
When the instrument is powered, it starts immediately to work
according to the parameters values loaded in its memory.
The instrument behaviour and its performances are gov-
erned by the value of the memorized 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 J input is programmed).
We recommend that you modify the parameter set to suit
your application (e.g. set the right input type, define the
alarms, etc.)
To change these parameters you will need to enter the “
Con-
figuration procedure
”.
6.1.1 Access levels to the parameter modifi-
cations and their password
The instrument have one complete parameter set.
We call this set “configuration parameter set” (or “configura-
tion parameters”).
The access to the configuration parameters is protected by a
programmable password (password level 3).
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (E.g. alarms, output functions, serial link).
Note:
Note the instrument will show only the parameters
consistent with the specific hardware and in accordan-
ce with the value assigned to the previous parameters
(e.g. if you set an output as “not used” the instrument
will mask all other parameters related with this output).
6.2 Instrument Behaviour at Power UP
At power up the instrument can show one of the following
information:
–
The display will show the measured value;
–
The display will show one alarm threshold;
–
The display will show programmed time of the timer.
in all cases:
–
The the programmed alarm are enabled;
–
The serial link is immediately operative.
We define the above conditions as “Standard Display”.
6.3 How to enter the Configuration Mode
1.
Push the
button for more than 3 seconds.
The display will show alternately
0
and «
PASS
».
2.
Using
and/or
buttons set the programmed password.
Notes: 1.
The factory default password for configuration
parameters is equal to 30.
2.
All parameter modification are protected by a
time out. If no button is pressed for more than 10
second the instrument return automatically back
to the Standard display, the new value of the last
selected parameter is lost and the parameter
modification procedure is closed.
When you desire to remove the time out (e.g. for
the first configuration of an instrument) you can
use a password equal to 1000 plus the programmed
password (e.g. 1000 + 30 [default] = 1030). It is
always possible to end manually the parameter
configuration procedure (see the next paragraph).
3.
During parameter modification the instrument con-
tinue 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 pro-
gramming procedure (its 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.
3.
Push the
button. If the password is correct the display
will show the acronym of the first parameter group prece-
ded by the symbol .
In other words the display will show:
The instrument is in configuration mode.
6.4 How to exit the Configuration Mode
Push the
button for more than 5 seconds.
The instrument will come back to the “standard display”
6.5 Funzione dei tasti durante la modifica
dei parametri
A short press allows to exit from the current parameter
group and select a new parameter group.
A long press allows you to close the configuration
parameter procedure (the instrument will come back
to the “standard display”).
When the upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.
Note:
The group selection is cyclic as well as the selection
of the parameters in a group.
6.6 Factory Reset - Default Parameters
Loading Procedure
Sometime, e.g. when you reconfigure an instrument previ-
ously used for other works or from other people or when you
have made too many errors during configuration and you de-
cided to reconfigure the instrument, it is possible to restore
the factory configuration.
This action allows you to put the instruent in a defined con-
dition (in the same condition it was at the first power up).
The default data are the typical values loaded in the instru-
ment prior to shipment from factory.
To load the factory default parameter set, proceed as follows:
1.
Press the
button for more than 5 seconds;
2.
The upper display will show “
PASS
” while the lower
display shows “
0
”;
3.
Press the
and/or
buttons to set the
-481
value;
4.
Press the
button;
5.
The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show
dFLt
(default) and then
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
