2.11.2 Unload batch cycle
The unload cycle control performed by the instrument is structured into operating steps which are
described in the following table.
PHASE FUNCTION
0
Batch is not activated and the instrument is waiting for the START command.
The instrument continuosly verifies if the value of gross load on balance is in the ZERO
band and eventually resets the “end of cycle” relay.
START is accepted only if all the following conditions have been verified:
⇒
the instrument is in operating mode (not in configuration, calibration test or clock set)
and in “idle “ condition (no batch cycle in progress)
⇒
the value of set 4 is greather than 0
If all the conditions are satisfied the instrument goes to phase 1.
1
This is the “Fast” unload phase.
⇒
The “fast” output is energized.
Upon reaching a net weight value equal to the
[set minus slowdown minus fly]
the instrument goes to phase 2 (“Slow” phase).
The Batch operation can be suspended by closing the PAUSE/ABORT input contact: all
the component command outputs are de-activated and a blinking message “
PAUSED
” is
displayed.
The Batch operation can be started again closing the ACK input contact or can be
permanently interrupted closing the PAUSE/ABORT input contact. In this case the
instrument clears the “Batch in Progress” and “Batch in Alarm” status, de-activates the
relative outputs and goes to phase 0 (Batch de-activated).
2
This is the “Slow” unload phase.
⇒
The “fast” output is deenergized.
⇒
The “slow” output is energized.
Upon reaching a net weight value equal to the
[set minus fly]
the instrument goes to phase 5 (Stabilization phase).
The Batch operation can be suspended by closing the PAUSE/ABORT input contact: all
the component command outputs are de-activated and a blinking message “
PAUSED
” is
displayed.
The Batch operation can be started again closing the ACK input contact or can be
permanently interrupted closing the PAUSE/ABORT input contact. In this case the
