:
Pressed and released allows to set the time delays
(if programmed with t.ed parameter). Pressed for 5 s
enters the parameters program mode, pressed again
accesses the parameters edit mode and confirms values.
In programming mode can be used together with the
key to change the programming level of the parameters.
When the keyboard is locked, the keys and , hold
pressed together for 5 s, unlocks the keyboard.

:
In parameteres program mode is used to decrease
the setting values and to select the parameters.
3.
:
In parameteres program mode is used to increase
the setting values and to select the parameters. In
programming mode can be used together with key to
change parameters level. Pressed together with the
key for 5 s allows the keyboard unlock.
4. -Start/Stop
:
Can be used for Start/Stop/Reset count
commands as programmed using the t.UF parameter;
5. LED SET: In normal operating mode, indicates the en-
tering to timings setting mode. In programming mode is
used to indicate the parameter programming level.
6. LED CNT: Indicates: count in progress (flashing with a
1 s frequency), count interrupted (on steady) or the reset
status (off);
7. LED OUT1: Indicates the OUT1 output status: ON (lit),
OFF (not lit);
8. LED OUT2: Indicates the OUT2 output status: ON (lit),
OFF (not lit).
2. PROGRAMMING
2.1 Fast Set Times programming
The normal mode to program the delay times (Set Times) is
done by shortly pressing key, the SET LED lights up and
display starts showing alternatively s.t1 (parameter acro-
nym) and its programmed value. To change the value press
the key to increase the number shown or to decrease
it. These 2 keys normally act in one digit steps a time, but
if kept pressed for more than 1 s the value increases or de-
creases faster and after 2 more seconds in the same condi-
tion, the speed further increases in order to quickly reach the
desired value. However, through t.edt parameter it is pos-
sible to define if and which Set Time can be set with the
short key. A further option provides the setting of S.T1 Set
Time value only, using the / keys without pressing in
advance the key (t.Ed = 8). t.ed parameter can assume a
value between oF and 8:
oF No Set Time can be set with the short key (if pressed
and released, the key has no effect);
1. Only s.t1 Set Time value can be set with this procedure;
2. Only s.t2 Set Time value can be set with this procedure;
3. s.t1 and s.t2 Set Times can be set with this procedure;
4. Only s.t3 Set Time value can be set with this procedure;
5. s.t1 and s.t3 Set Times can be set with this procedure;
6. s.t2 and s.t3 Set Times can be set with this procedure;
7. s.t1, s.t2 and s.t3 Set Times can be set with this procedure;
8. s.t1 Set Time value can be set directly using / .
For example, in case the parameter tEdt =
1
or
3
, the pro-
cedure is the following:
–Press and release the key, the display shows S.t1 alter-
nated to the S.t1 value.
–To change the Set Time, press the key to increase the
value or to decrease it.
–If tEd =
1
, once the desired value ha been set, press the
button to exit the fast programming mode.
–If tEd =
3
, pressing and releasing again the button the
display shows S.t2 alternated to its value. To change the
value use the / keys as for the S.t1 value.
–Once the Set Time time has been programmed, press the
key to exit the Set Time programming mode.
To exit the fast Set Time programming mode push the
key after the last Set Time time has been displayed or press-
ing no buttons for about 10 s, after which the display returns
to normal operation.
S.t1 and S.t3 can be set within the limits established by pa-
rameters S.Lt1 and S.Ht1 while S.t2 within the limits estab-
lished by S.Lt2 and S.Ht2.
2.2 Standard mode parameters setting
To access the instrument function parameters when pass-
word protection is disabled, press the key for 5 s, after
which the display shows the code that identifies the first
programmable parameter; use the / keys to select
the desired parameter then press 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 the key again: the new value
is stored and the display shows only the code of the modi-
fied parameter. Pressing the or keys, it is possible to
select another parameter and change it as described. To exit
the programming mode, press no keys for 30 s or keep the
key pressed for 2 s, the timer returns showing the actual
count value.
