FUNC OUT
n
The isolated output can function as either a passive 4-20 mA output, or a
pulse/logic open collector output:
•
RETRANS - Retransmit totals as a pulse output or rates type
variables as a 4-20mA signal.
•
OP-ERR - An error signal that will become active for the no flow,
overflow or leakage error conditions.
•
OP-CTRL - A control signal that is active during a batch, can be
used as a pump control or indicator.
•
OP-RST - A control signal that produces a 300ms pulse that can
be used to reset remote counters etc. Activates when the controller’s
total(s) are reset.
•
OP-END - A control signal that reflects the End of Batch
condition (Note: not applicable if Batch mode is ON-OFF).
Press or to select the function required.
PULSE OUT
n
or
4-20
If above function is set for retransmission, 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.
