4-20
You can assign any of the “main menu” variables to an output. The nature
of the output depends on the assigned variable. Totals are output as pulses
and rates are output as 4-20 mA passive signals.
Press or to select the variable that is required as an output. The
top of the display shows the type of output signal that is assigned to the
variable.
CAUTION
Due to the dual-purpose nature of the outputs, take care not to
set the output as an open collector pulse type signal when
connected to a 4-20 mA loop circuit.
WIDTH OUT
n The Output Pulse Width is available for viewing and editing only when
the assigned variable is a total (pulse output) type.
Pulse output is usually used to drive remote counters. Set the pulse width
(in milliseconds) as required by the remote counter.
Press or to set to: 10, 20, 50, 100, 200 or 500 ms.
PULSE OUT
n The Output Pulse Factor is available for viewing and editing only when
the assigned variable is a total (pulse output) type.
The Output Pulse Factor is the scaling factor for the retransmission of the
measured total quantity.
For example, if “volume” is chosen as an output variable and engineering
unit is cubic metres, then a pulse factor of 1.000 generates one pulse for
1 m
3
. Similarly, a pulse factor of 3.000 generates one pulse for 3 m
3
.
For more information, see Output Pulse Factor on page 44.
The output pulse factor cannot be 0 (zero).
