EXAMPLES OF TIME COUNTER CONFIGURATION
Due to big number of parameters some tasks must to be explained.
Starting the counting
If parameter start
„StArt”
has been set to
„Lo-Hi”
or
„Hi-Lo”
counting can be started in three
ways:
• using external signal connected to terminal {
START
},
•
using local keyboard and pressing button
[^]
(parameter
„PuSH”
must to be active)
• setting bit 0 of control word, using RS 485 interface
(parameter
„mbAc”
must to be set
“on”
).
If parameter
„StArt”
has been set to
„Lo”
or
„Hi”
starting of the counter can be done
exclusively using external signal {
START
}. Other possibilities are blocked.
Stopping the counting
If parameter
„StArt”
has been set to
„Lo-Hi”
or
„Hi-Lo”
stopping of the counter can be done
in three ways:
• using external signal connected to terminal {
STOP
},
•
using local keyboard and pressing button
[v]
(parameter
„PuSH”
must to be active)
• setting bit 1 of control word, using RS 485 interface(parameter
„mbAccE”
must to be set
“on”
).
If parameter
„StArt”
has been set to
„Lo”
or
„Hi”
sopping of the counter of the counter can
be done
exclusively using external signal {
START
}. Other possibilities are blocked.
Clearing of the counter
Clearing of main counter and totalizer can be made in one of following ways:
• using external signal {
RESET
} - main timer only.
• Pressing button
[RESET]
on counter front panel (if
„PuSH”
option is active) – currently
displayed counter will be cleared only
•
setting bit 2 of control word using RS 485 interface clears main timer (parameter
„mbAccE”
must to be set
“on”
).
•
setting bit 2 of control word, using RS 485 interface clears totalizer (parameter
„mbAccE”
must to be set
“on”
).
It is possible to control the counter from more than one source during one measurement for
example:
• starting is done using local keyboard, and stopping using RS 485 interface;
• starting by external signal {
START
}, clearing via RS 485 interface and stopping using local
keyboard
It is possible to disable control of the counter from local keyboard or RS 485 interface, by
setting corresponded parameters in programming menu.
Clearing of the counter do not stop the counting.
If parameter „rESEt” has been set to „Lo” or „Hi” and start of the counting (from any source)
occurs while signal { RESET } is in active state, then counting starts after { RESET } line will
change its state.
