PD4-6624 & PD4-6628 Loop-Powered Flow Rate/Totalizers

Isolated 4-20 mA Output (
4-20 mA
)
The
4-20 mA
menu is used to scale the 4-20 mA output based on display values. This menu is not present on models
without a 4-20 mA output option.
The 4-20 mA analog output (if equipped) can be scaled to provide a 4-20 mA signal for the rate or total display range
or to simply retransmit the 4-20 mA input. The output may be disabled (
DISABLE
) and will only output the minimum
signal.
Overrange and underrange values determine what mA signal the meter will output if the mA input is underrange
(<3.5 mA) or overrange (>20.5 mA). This value may be set to 1 mA, 3.5 mA, 3.8 mA, 20.5 mA, 20.8 mA, 23 mA,
or disabled.
No equipment is needed to scale the analog output; simply program two display values and corresponding mA output
signals.
Rate or Total (
RATE
or
TOTAL
)
To scale the analog output, enter display value 1 and a corresponding analog output value for this display, then enter
display value 2 and a corresponding analog output value for this display value. This will provide a linearly scaled
analog output.
Retransmit (
RETRANS
)
This option will retransmit the 4-20 mA analog input without the need to scale the output.
Output Manual Control (
CONTROL
)
The
Control
menu is used to control the open collector outputs, 4-20 mA analog output, or the relays manually,
ignoring the input. Each open collector, relay, and analog output can be programmed independently for manual
control. Selecting automatic control sets all relays and analog output for automatic operation.
After selecting manual control for a specific output, you can set the output value. To change the output value, return
to the Control menu, select the output to control, select manual control, and enter a new input.
