6.4.4
NET/GROSS weight display at the end of unloading activity
It is possible to decide to have at the end of the unloading activity, the visualization of the remaining weight
(gross weight on the scale) or the unloaded weight (negative net weight).
Normally the remaining gross weight is shown on the display, by setting the WEIGHT DISPLAY ON
UNLOADING step on NET (
) only the unloaded weight will be shown.
This can be useful if one wants to know exactly the unloaded material quantity before proceeding with the
following activity, especially when the weight is in tolerance, and therefore the unloading would
automatically end without possibility to show the unloaded weight.
6.5
“Pause” type of an activities
a) Description
This activity has the purpose to interrupt the dosage in the case an operation must be executed by the
operator or automatically with the use of the enabled relative output:
-
This activity automatically starts at the end of the previous one.
-
It foresees that it is manually ended by the operator; in fact, the operator must give the dosage end
command.
-
It does not foresee a target weight to reach: normally the eventual weight added is not stored; it is
possible to decide to store the weight added during the pause activity by enabling the
ADD TO
CONSUMPTION DURING PAUSE
(
), and, in this case, the dosage of the eventual materials
necessary for this activity must be manually stopped.
-
During the PAUSE activity, it is possible to pause the dosage (through the external INPUT 2 input or
the PAUSE button) disabling all the active outputs.
-
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
PAUSE
message.
-
To end the dosage, the operator will press for an instant the external INPUT 2 or PAUSE button
again or the external INPUT 8 (Pause activity advancement mode
), so that:
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.
6.6
“Timer” type of an activities
a) Description
This activity has the purpose of enabling, for the programmed time, an output, which can be connected to a
stirrer, a mixer, a burner, or, generally, to a device which should be enabled for a pre-established time and
disable itself automatically:
-
This activity automatically starts at the end of the previous one.
-
It is possible to set in the activity database the type of timer which one wants to use:
1) Stoppable:
the timer activity may be also terminated at any time manually by pressing for an
instant the external INPUT 1 / START button or the external INPUT 7 (depending on the
TIMER
