Example 2

The following example uses seven setpoints to control
a two-speed fill operation where both fast and slow
feeds are on simultaneously.
Digital inputs 1 and 2 are assigned to batch start and
batch run functions: BATRUN must be on (low)
before the BATSTRT input starts the batch.

DIGIN2=BATRUN
BATCHNG=MANUAL
Setpoint 1 ensures that the scale is empty (0±2

Setpoint 3 waits for standstill, then tares the container

Setpoint 4 starts the fast fill operation. When the net
weight reaches 175 , the setpoint trips and digital

Setpoint 5 controls the slow fill operation. When the
net weight reaches 200
(see Setpoint 7), the indicator waits for standstill and
performs a push print operation using the SPFMT

Setpoint 6 is a continuous setpoint, used to allow the
slow feed output to be on at the same time as the fast
fill. The slow fill output (digital output 2) is turned on
when setpoint 4 (fast fill) starts and remains on until
setpoint 5 begins.
