SET POINTS PROGRAMMING
For SET POINTS programming access, proceed as follow:
- Press key ‘PRG’ in impulsive mode; on display appears:
0¨0¨20
P. = Time of PAUSE, programmable between 1 cent of second and 9999h59m (depending on
the programmed scale). If programmed = 0 it automatically reprograms itself to 1 sec.
0¨0¨20
L. = Time of WORK, programmable between 1 cent of second and 9999h59m (depending on
the programmed scale). If programmed = 0 it automatically reprograms itself to 1 sec.
Key ENT confirms the data and passes to the successive programming. In order to exit the programming, press key PRG.
PROGRAMMING OF THE OPERATION PARAMETERS
The programmable parameters are divided in two groups and protect with a 4 figures code.
In order to approach the programming, proceed in the following way:
- Press key
PRG
for about 2 sec. On the display appears:
» 0000
GROUP 1
:
insert code
2357
and press
ENT
.
t.i. = Intermediate Time, programmable between 0.0 and 99.9 sec. This time comes
executed, if programmed various from 0, between the PAUSE time and the WORK time).
During the execution of this time the output is not active.
SCL. = Time Scale. Selection of the maximum time scale of the timing. It’s possible to choose
between 4 different time scales:
1 = 59m59s99c - 2 = 99h59m59s - 3 = 9999h59m - 4 = 9999s99c
Count UP / DOWN / Superior.
Count = Up: the timer gets ready to visualize the timing in increasing way (UP), starting from
zero up to the programmed value of set point.
Count = dn: the
timer
gets ready to visualize the
timing
in decreasing way (DOWN), starting
from the programmed value of set point to zero.
Start in PAUSE or in WORK mode.
Str. = P. : the cycle starts executing the PAUSE time
Str. = L. : the cycle starts executing the WORK time

.
9999
Û
c. = CYCLES PREDETERMINATOR, programmable between 0 and 9999; with this parameter
is possible to program how many cycles of PAUSE/WORK the instrument must execute. At the
end of the cycles number, the sequence comes interrupt. To restart the sequence it is
necessary to reset the predeterminator. If the value is programmed = 0 the function is excluded
and the sequence goes to infinite. Pressing the
ù
key the display shows the decreasing value
of the predeterminator; pressing another time the key the display shows the current timing.
