GENERAL DESCRIPTION
The PAXDR is a 5-digit Dual Rate Indicator and 6-digit Dual Totalizer in a
single meter. Two Rate and two Total displays are provided (A and B), along
with two additional calculation displays (C) to show the Sum, Difference, Ratio,
% of Total or Draw between A and B displays. Any of the six displays are
viewable: A, B or C Rate and A, B or C Total. The meter’s LED display has
0.56" digits, available in red sunlight readable or standard green. The display
intensity is adjustable for low level lighting conditions up to sunlight readable
applications.
The meter has two signal inputs from which the Rate and Totalizer values are
derived. For the Rate displays, up to 10 point scaling is provided for each input,
to scale non-linear rate processes. Separate scaling is provided for both the A
and B Totalizers. The independent scaling allows for Rate only, Totalizer only
or combination Rate/Totalizer applications, with or without the calculation
displays.
While suitable for many applications, this meter is ideal for flow measurement
where both flow rate and flow volume are measured. Two separate flow lines
can be monitored simultaneously, each scaled to convert flow to a common unit
of measure. Flow rate is easily scaled to read flow per time period (sec/min/hr).
The flow rate and volume for each line can be shown, as well as the Sum,
Difference, Ratio, etc. between the two lines for flow rate and/or volume. A
different calculation function may be used for Rate and Total if desired.
Optional plug-in cards provide up to four setpoint outputs, a linear DC output
and communications capability. The Plug-in setpoint cards provide dual
FORM-C relays (5 A), quad FORM-A relays (3 A), or either quad sinking or
quad sourcing open collector logic outputs. The outputs can be assigned to any
of the Rate or Totalizer display values, and configured to suit a variety of control
and alarm requirements.
The linear DC output Plug-in card provides either 20 mA or 10 V signals. The
output can be scaled independent of the input range and can track any of the
Rate or Totalizer displays.
Communication and Bus Capabilities are also available as option cards.
These include RS232, RS485, Modbus, DeviceNet and Profibus-DP. Readout
values and setpoint alarm values can be controlled through the bus. Additionally,
the meter has a feature that allows a remote serial device to directly control the
meter outputs.
The PAXDR is available in AC or DC powered versions. The meter has been
specifically designed for harsh industrial environments. With NEMA 4X/IP65
sealed bezel and extensive testing to meet CE requirements, the meter provides
a tough yet reliable application solution.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in this
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this meter to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the meter.
