5.3.2 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 3 seconds. The upper

display will show

PASS

while the lower display will show

Using

and

buttons set the programmed password.

Notes: 1.

The factory default password for configuration
parameters is equal to 30.

During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration chan-
ge 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 will show the acronym

of the first parameter group preceded by the symbol:

]

In other words the upper display will show:

]inp

(group of the

Input parameters

The instrument is in configuration mode.

5.4 HOW TO EXIT THE “CONFIGURATION

MODE”

Push

button for more than 3 seconds, the instrument will

come back to the “standard display”.

5.5 KEYBOARD FUNCTIONS DURING

PARAMETER CHANGING

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.

These two keys allow to return to the previous

group. Proceed as follows:

Push the

button and maintaining the pressure,

then push the

button; release both the buttons.

Note:

The group selection is cyclic as well as the selection
of the parameters in a group.

5.6 FACTORY RESET - DEFAULT

PARAMETERS LOADING PROCEDURE

Sometime, e.g. when you re-configure an instrument
previously used for other works or from other people or when
you have made too many errors during configuration and
you decided to re-configure the instrument, it is possible to
restore the factory configuration.
This action allows to put the instrument in a defined
condition (the same it was at the first power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:

Press the

button for more than 5 seconds. The upper

display will show

PASS

while the lower display shows

;

Using

and

buttons set the value -481;

Push

button;

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.

The procedure is complete.

Note:

The complete list of the default parameters is available
in Appendix A.

5.7 CONFIGURING ALL THE PARAMETERS

In the following pages we will describe all the parameters of
the instrument. However, the instrument will only show the
parameters applicable to its hardware options in accordance
with the specific instrument configuration (i.e. setting

AL1t

[Alarm 1 type] to

nonE

[not used], all parameters related to

alarm 1 will be skipped).
