External Control mode
Suppose high speed batching scale is provided at site: Industrial control PLC will combine
with the instrument to sort out the cargos quickly. PLC will control the cargo to the weighing
platform. A signal will be triggered to the instrument after the cargo is loaded to make the
weighing platform calculate the weight. The weight scope of the users’ qualified product is 9.90kg
~ 10.10kg and the channel signal, which can be controlled by PLC to deliver to different channels,
will be sent according to the weight scope. The time for one cycle is about 3~5 seconds. The
instrument should be used together with PLC. We can set the parameter in SET 2 according
to table 8-3 (suppose that there are 2 decimal digits during calibration):
Table 8-3 Parameter Setting Example of Batching scale in External Control Mode
Set parameter 13A inSET 1to 3. Set parameter inSET 2as follows:
Parameter
Setting Instruction
1
[ 1]
[CtrL ]
Choose the peak holding mode.
2
[ 02]
[t0 ]
The cargo is already on the weighing
platform when the triggering signal is
received. Long time delay is not
required
3
[ 10]
[t1 ]
It is enough to take 1 second to calculate
the weight.
4
[ 00]
[t2 ]
Inform PLC to move the cargo
immediately after calculation is
finished. Long time delay is not
required.
5
[ 10]
[t3 ]
Send the channel signal with interval of
1 second and ensure it is received by
PLC.

Set zero zone, which should be totally
different form the qualified lower limit.
