Tip for you: The operators can correct the value
within the permitted range without greatly affecting
the correct work of the feeder.
8.7. A19 Input IN1
Determining the use of digital input IN1.
Not used – The input is not used or is only monitored
and its state is transferred to the output
(Chapter 8.12).
Start – The +24V signal must be supplied so that the
feeder can be activated. If the remaining
conditions are fulfilled as well (according to
the configuration for additional inputs), then
upon supply of the 24V signal the feeder will be
in the R-run status. Otherwise, the feeder is in
the W-wait status. Switching from the W to R
status and vice versa is immediate, the
parameters A12, A13 do not affect this.
Tip for you: Use this setting if the feeder
is controlled from a master control system.
Maximum stock - The sensor is connected to the input
monitoring the maximum stock in the storage tank
being filled by the feeder. If the sensor is
active during the period stated by the parameter
A13, the feeder is stopped and switched to the
W-wait status. Returning to the R-run status
depends on whether the second input is defined as
the minimum stock. If so, the feeder is activated
according to the status of this sensor (see
below). The feeder is switched to the R-run
status after the maximum stock sensor is not
active for the time stated by the parameter A12.
Tip for you: By setting parameters A12, A13
properly only one sensor is sufficient for
monitoring the storage tank.
Minimum stock – This setting is only used if the
second output is defined as the maximum stock.
The sensor monitoring the minimum in the storage
tank is connected to the input being filled by
the feeder. The feeder is switched to the R-run
status after the minimum stock sensor is not
active for the time stated in parameter A12. If
