GENERAL DESCRIPTION

The E1931X402 Dual Process Input Meter o_ers many features and
performance capabilities to suit a wide range of industrial
applications. Available in two models, AC or DC power, the meter
has the capability to accept two, 4 to 20 mA or 0 to 10 VDC input
signals. Each input signal can be independently scaled and
displayed. In addition, a math function can be performed on the two
signals, C + A + B, C - A - B, C + A - B, AB / C, CA / B, or C (A / B -

1). Any of the three meter values can have Alarms, Comms, and/or a
Retransmitted Analog Output capability by simply adding optional
cards. The optional plug-in output cards allow the opportunity to
con_gure the meter for current applications, while providing easy
upgrades for future needs.
The update rate of the meter is user selectable. This will help in
those applications where a quick response from the meter is of the
utmost importance. The rate can be adjusted from eight selections
with a minimum of 5 updates/second to a maximum of 105
updates/second. The meters employ a bright 0.56" (14.2 mm) red
sunlight readable LED display. The intensity of display can be
adjusted from dark room applications up to sunlight readable,
making it ideal for viewing in bright light applications.
The meters provide a MAX and MIN reading memory with
programmable capture time. The capture time is used to prevent
detection of false max or min readings which may occur during start­up or unusual process events. The signal totalizer (integrator) can be
used to compute a time-input product. This can be used to provide a
readout of totalized _ow, calculate service intervals of motors or
pumps, etc. The totalizer can also accumulate batch operations.
The meter has four setpoint outputs, implemented on Plug-in option
cards. The Plug-in cards provide dual FORM-C relays (5A), quad
FORM-A (3A), or either quad sinking or quad sourcing open collector
logic outputs. The setpoint alarms can be con_gured to suit a variety
of control and alarm requirements. Communication and Bus
Capabilities are also available as option cards. The standard output
is in Modbus Protocol. Any of the following option cards, RS232,
RS485, DeviceNet, or Pro_bus can be used with the meter. Readout
values and setpoint alarm values can be controlled through the bus.
Additionally, the meters have a feature that allows a remote
computer to directly control the outputs of the meter.
A linear DC output signal is available as an optional Plug-in card.
The card provides either 20 mA or 10 V signals. The output can be
scaled independent of the input range and can track either the input,
totalizer, max/min readings, or math calculation value. Once the
meters have been initially con_gured, the parameter list may be
locked out from further modi_cation in its entirety or only the setpoint
values can be made accessible. The meters have been speci_cally
designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise
e_ects to 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 speci_ed by the manufacturer, the protection
provided by the equipment may be impaired. Do not use this unit
to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful

2. Installing the meter

Installation

The meter meets NEMA 4X/IP65 requirements when properly
installed. The unit is intended to be mounted into an enclosed panel.
Prepare the panel cutout to the dimensions shown. Remove the
panel latch from the unit. Slide the panel gasket over the rear of the
unit to the back of the bezel. The unit should be installed fully
assembled. Insert the unit into the panel cutout. While holding the
unit in place, push the panel latch over the rear of the unit so that the
tabs of the panel latch engage in the slots on the case. The panel
latch should be engaged in the farthest forward slot possible. To
achieve a proper seal, tighten the latch screws evenly until the unit is
snug in the panel (Torque to approximately 7 in-lbs [79N-cm]). Do
not over-tighten the screws.

3. Reviewing the front buttons and display

Installation Environment

The unit should be installed in a location that does not exceed the
maximum operating temperature and provides good air
circulation. Placing the unit near devices that generate excessive
heat should be avoided. The bezel should be cleaned only with a
soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may
accelerate the aging process of the bezel. Do not use tools of any
kind (screwdrivers, pens, pencils, etc.) to operate the keypad of
the unit.
