DOSAGE

STOPPING MODE
).
2) Not stoppable:
It’s not possible to stop the timer before the end that has been set.
-
It does not foresee a target weight to be reached: normally the eventual weight added is not stored;
it is possible to decide to store the weight added during the timer activity by enabling the
ADD TO
CONSUMPTION DURING TIMER
(
), and, in this case, the dosage of the eventual material
necessary for this activity must be manually stopped.
-
During the TIMER activity, it is possible to pause the dosage (through the external INPUT 2 input or
the PAUSE button) disabling all the active outputs and freezing the timer at the reached time. To
resume the activity, press the external INPUT 1 or the START button: the instrument will restart
counting from the frozen timer value.
-
If the instrument turns off during the timer activity, when the instrument turns back on, it goes into
the dosage pause status; by pressing the external INPUT 1 or the START button, the timer is reset
and the counting restarts from 0.
-
Once the dosage is started the instrument tares the weight on the scale and enables the eventual
linked output
-
The display, during the pause activity, shows the
TIMER
message.
-
The activity automatically ends when the set time has passed:
1)
The eventual linked output will be disabled.
2)
The data of the eventual executed dosage is automatically stored and transmitted through the
serial line for the printing or the storage on PC/PLC.
-
A wait time starts equal to the DATA READING TIME
(
) in order to allow the reading of the
activity data; the instrument waits for this time before passing to the following phase.
b) Alarm output and activation mode of next activity
If the timer is stoppable, it is possible to:
1) Decide to enable an error if the timer is stopped before its end, by setting the
ALARM MODE
DURING
TIMER ACTIVITY
(
):
-
The
ALARM
message is signalled, and the error output (default = OUT3) is enabled when the
activity is stopped.
-
To resume the activity, press the external INPUT 1 or the START button: the timer is reset and the
counting restarts from 0.
This can be useful if the timer stopping (through the INPUT 1 or INPUT 7) is caused by an error on the
device enabled during the set time: this device supplies a signal on the input when this error occurs.
2) Decide to pass to the following activity when the timer is stopped and have instead an error if it is not
stopped and the timer ends, by setting the
ALARM MODE
DURING TIMER ACTIVITY
(
):
-
The
ALARM
message is signalled, and the error output (default = OUT3) is enabled if the activity is
not stopped during the set time.
-
To resume the activity, press the external INPUT 1 or the START button: the timer is reset, the
counting restarts from 0 and the instrument waits again for the time stop during the set time to
pass to the following activity.
This can be useful if the purpose of the activity is to define a maximum time in which the device must be
enabled and give a response to the instrument in order to proceed, or an error if a signal is not given.
