Description
Starts an individual dosing cycle.
Starts n dosing cycles in continuous succession Continuous operation
ends automatically if a total set point (DR21) was specified and reached
or alternatively using the "Stop continuous mode (1123)" command. If a
dosing cycle is still active, it is completed. The "Abort weighing (1124)"
command also ends continuous operation but does not terminate an
active dosing cycle.
The "Continuous mode active" bit in the AWI status (DR30) indicates
whether or not the electronic weighing system is operating in continuous
mode.
Current weighing cycle is stopped and the "Weighing cycle stopped" bit
is set in the AWI status (DR30). The "Continue weighing (1141)" com‐
mand can be used to continue and thus complete the cycle from this
status.
If check stop points have been defined (see section Check stop [check‐
StopAfterStep0 to checkStopAfterStep7] (Page 99)), these are activa‐
ted by "Activate check stop" and the weighing cycle stops at the speci‐
fied points.
Continuous operation is stopped. If the command is issued within a
weighing cycle, this weighing cycle is first completed, and the electronic
weighing system then waits in weighing step 0. The "Continuous mode
active" bit in the AWI status (DR30) is reset.
The current dosing cycle is directly aborted, and the electronic weighing
system jumps immediately to weighing step 0.
The command can be issued within the weighing cycle or outside of it
(=weighing step 0). Any active coarse or fine signal is directly reset, a
tolerance check is performed, a log print is created and – if configured in
DR25 –the scale is emptied. The electronic weighing system then waits
in weighing step 0.
In DTI mode, the command shuts down the dosing signals and starts the
emptying process. The material in the scale is still totaled. Loading is
then stopped and totalizer 1 is written to the alibi memory. When the
weight in the scale at the time of the rest emptying command is less than
the emptying limit from DR06, emptying takes place based on time. To
do this, specify a corresponding "Discharge time (s)" in DR25.
The command can be issued only in weighing step 0. The "Emptying
signal" bit is then set to TRUE and a linked digital output, if any, is set.
The command is used to clean the scale or to open it manually for serv‐
ice.
The command can be issued only in weighing step 0. The "Emptying
signal" bit is then set to FALSE and a linked digital output, if any, is reset.
The command is used to clean the scale or to close it manually after
service.
