Description
F9B
Example for F9B hook-up
Digital pulse output, batch counter
Pin 5 is pulled down to 0Vdc when a given batch size is
reached (during a given pulse length).
By default, a pulse is given at each 1x the
Counter unit
batch
value, with a pulse length of 1 second. For instance, when
Counter unit
is set to 'ln', a pulse is given each time 1 ln has
passed through the instrument. An alternative pulse length
must be specified on order.
Provide a pull-up resistor of 5…10 kOhm to create 15…24 Vdc at pin 5 (according to the applicable hook-up
diagram).
I3C
Digital input, controller mode valve close
Valve closes when pin 5 is connected to 0 Vdc.
This option switches between the default
Control mode
and mode ‘Valve Close’ (value 3). When the default
Control mode
is digital, the default value is 0 (bus/RS232), when the default
Control mode
is analog, the
default value is 1 (Analog input).
I8C
Digital input, controller mode valve purge
Valve is fully opened when pin 5 is connected to 0 Vdc.
This option switches between the default
Control mode
and mode ‘Valve Fully Open’ (value 8). When the
default
Control mode
is digital, the default value is 0 (bus/RS232), when the default
Control mode
is analog,
the default value is 1 (Analog input).
I1R
Example for I1R or I2R hook-up
Digital input, reset counter
The counter resets when pin 5 is connected to 0 Vdc.
I2R
Digital input, reset alarm
The alarm resets when pin 5 is connected to 0 Vdc.
