Through ‘Config’ parameter is selected one of the two possible schemes of action:
MODE А – Dispenser/ Batcher
●
Declines in the graph are eventual interference or vibrations. If the measured value has
reached a certain set-point the respective output become active and it is active whether
the measured value falls below the set-point. The output is active till the pressing the
Stop
button, timeout
tOff ≠ 0
or reaching the last dose.
After power supply voltage the device is waiting for start of
Zero/Start
input. An active
level of this input starts the process.
K1
output becomes active. When reaching
dose 1,
K
1
becomes inactive and
K2
becomes active. When reaching
dose1+dose2,
K2
becomes
inactive and
K3
becomes active. When reaching
dose1+dose2+dose3, K3
becomes
inactive. Next start – in transition from inactive to active level of
Zero/Start
input.
Sequence of switching
Start→К1→К2→К3→Stop
can not be changed.
The controller gaps one or more stages if the weight at start exceeds their set-points.
The whole process is limited in time by
tOff
parameter.
Start can be configured (parameter
ConFiG
) with or without taring.
It is permissible integration of inputs
Tare
and
Zero/Start
with which is obtained taring at
startup.
Start by active level of input
Zero/Start
when switching on the power supply voltage have to
be weighed against the option “tare at startup”. If the option is active or if inputs
Zero/Start
and
Tare
are integrated can be used a pulse not constant input signal to avoid re-tare in power
supply failure and restoration.
On the front panel there is a
Start/Stop
button which is with analogous function or stops the
process if it is already started.
Inversion of the outputs is possible (parameter
ConFiG
).
Parameters
dose1, 2 and 3 are dosing
set-points (for example when mixing various
ingredients)
