3.4 - ELECTRICAL CONNECTION DRAWING
4 - OPERATING MODE
4.1 – FUNCTIONING OF THE COUNTING COMMANDS
The counting can be enabled and disabled through the frontal key T,
or through the remote inputs CNT EN and RES.
The operating mode of the key T is defined by the parameter
"t",
the operating mode of the input CNT EN is defined by the parameter
"E"
while the input RES always works as reset, i.e. it stops and
resets the counting when it is activated and moreover it has priority
on the other commands (when it is activated it doesn't allow the
starting of the counting).
When the instrument is predisposed for the continuation of the
counting also without power supply, during the counting under
conditions of lack of supply the only active command is the RESET
one, which can be given only from the frontal key T.
When the instrument is supplied through the battery it is not
therefore possible to make the counting start again once stopped.
4.2 – FUNCTIONING OF THE DISPLAY
The led SET/CNT is used to indicate the access into the
programming (flashing fast), the counting in action (flashing each
second), the counting interrupted before the term (lighted fixed) or
the counting finished and the state of reset (off).
After the reset, the display visualizes 0000 if the counting mode is
programmed as UP (par.
"C"
= 1) or it visualizes the programmed
set value if the counting mode is programmed as DOWN (par.
"C"
=
2).
During the counting, the display visualizes the value of time that
spends in UP or in DOWN mode.
If the back-up mode has been programmed to continue the counting
in action without power supply, the display remains lighted but with
an inferior brightness (with the purpose to limit as much as possible
the absorption from the battery).
4.3 - OUT1 OPERATING MODE
The instrument can be programmed by the parameter
"F1"
to
operate in any of the following 5 modes:
F1 = 1 - DELAYED :
On receiving the START signal, the instrument starts counting time.
When the set time value “t1” has been reached, the instrument
enables the output OUT1.
The output is disabled by the RESET signal.
F1 = 2 - FEEDTHROUGH :
On receiving the START signal, the instrument enables the output
OUT1.
The output is disabled when the set time value “t1” has been
reached.
The output will be enabled again after the transmission of a RESET
signal and a subsequent START signal.
F1 = 3 - ASYMMETRICAL OSCILLATOR START ON:
This operating mode allows the user to enter two SET times “t1” and
“t2”, and therefore also involves the "S2" parameter .
On receiving the START signal, the output OUT1 is immediately
enabled and remains enabled for the time period t1.
Then the output is disabled and remains disabled for the time period
t2.
This procedure goes on until a RESET signal is transmitted.
F1 = 4 - ASYMMETRICAL OSCILLATOR START OFF:
This operating mode allows the user to enter two SET times “t1” and
“t2”, and therefore also involves the "S2" parameter .
On receiving the START signal, the output remains disabled until
the set time period “t1” has expired.
Then the output is enabled.
The output is disabled again when the set time period “t2” has
expired. This procedure goes on until a RESET signal is transmitted.
F1 = 5 - ONE CYCLE ASYMMETRICAL OSCILLATOR START OFF:
The operation results similar to the "F1"=4 with the only difference
that only one cycle of OFF/ON is performed.
To the start signal the output OUT1 remains disabled for the time
“t1".
When the time “t1” is expire the output will be on for the time “t2”.
The cycle will be enabled again after the transmission of a RESET
signal and a subsequent START signal.
