Standard mode parameters programming
To access the instrument function parameters when pass-
word protection is disabled, press the keys
/ and
/
at the same time and keep them pressed for about 5 s, after
which the display shows the code that identifies the first pro-
grammable parameter. Press the
/
keys to display the
desired parameter, then, pressing the
/ key, the display
shows the parameter code alternated to its value that can be
changed with the
and
keys.
Once the desired value has been set, press
/ again: the
new value is stored and the display shows only the code of the
selected parameter. Pressing the
/
keys, it is now pos-
sible to select another parameter and change it as described.
To exit the program mode, press no keys for about 30 s or
keep the
/ key pressed for 2 s.

Note:
With parameters in which the variable to be set is a time,
the least significant time unit (s when s/min, min when
min/h) is displayed in negative form (with the sign -); the
most significant time unit (m when s/min, h when min/h)
is displayed as a positive value (without the sign).
2.3
Parameter protection using a Password
The instrument has a parameter protection function using a
password that can be personalised through the
tPP
parameter
To protect the parameters, set the desired password number
in the parameter
tPP
.
When the protection is active, press the keys
/ and
/
at the same time and keep them pressed for about 5 s, after
which the display shows
r.p
. Now press only the
/ key,
the display shows
0
; using the
/
keys, insert the pro-
grammed password number and press the key
/ again.
If the password is correct the instrument displays the code of
the first parameter and it will be possible to program the in-
strument in the same way described in the previous section.
The password protection can be disabled by setting
tPP
=
oF
.

Notes: 1.
All parameters are configured by default at
“protected” level so that setting the
PP
parameter
protects all parameters with the password.
2.
If the Password gets lost, just switch OFF and ON
the instrument, push
/ key during the initial
test keeping it pressed for 5 s. In this way it is
possible to access all the parameters, verify and
modify the parameter
tPP
.
2.4
Customized mode parameter programming
(parameters programming level)
The password hides all the configuration parameters behind a
factory set password to avoid unwanted changes to the con-
troller parameters. To make a parameter accessible without
having to enter the password when
tPP
password protection
is activate, use the procedure that follows:
Enter the program mode using the
tPP
Password and select the
parameter that must be accessible (no password protection).
Once a parameter is selected, if the
dp LED flashes
the
parameter is programmable by entering the password (is
“
protected
”). If the
dp LED is steady ON
the parameter is
programmable without password (is “
unprotected
”).
To change the parameter visibility, press the
/ key and
keeping it pressed also press the
button.
The
dp LED
changes its state indicating the new level of
parameter accessibility (
ON
= not protected;
flashing
= password protected).
In case some parameters are not protected, accessing
the the programming mode the device first shows the not
protected parameters, then the
r.p
parameter (through which
will be possible to access the “protected” parameters).

Reset parameters to default value
The instrument allows the reset of the parameters to values
programmed in factory as default
To restore the default parameters value set value
-48
at
r.p
password request Therefore, to make the reset to the default
parameters, enable the Password using the
tPP
parameter
so that the
r.p
setting is requested, at this point insert
-48
instead of the programmed access password.
Once confirmed the password with the
/ key the display
shows “
---
” for 2 s therefore the instrument resets all the
parameters to factory default setting.
2.6
Keyboard lock function
On the instrument it is possible to completely lock the keyboard.
This function is useful when the controller is in an accessible
area and the changes must be avoided.
To activate the keyboard lock it is enough program the pa-
rameter
tLo
to a value different from
oF
.
The
tLo
value is the keys inactivity time after which the key-
board will be automatically locked.
Therefore, pressing no buttons for the time set at
tLo
, the
instrument automatically disables the keys normal functions.
