WARNING: Disconnect all power to the unit before
installing Plug-in cards.
Adding Option Cards
The MPAX series meters can be fitted with up to three optional plug-in cards.
However, only one card from each function type can be installed at a time. The
function types include Setpoint Alarms (PAXCDS), Communications
(PAXCDC), and Analog Output (PAXCDL). The cards can be installed initially
or at a later date. Each optional plug-in card is shipped with installation and
programming instructions.
COMMUNICATION CARDS (PAXCDC)
A variety of communication protocols are available for the PAX and MPAX
series. Only one of these cards can be installed at a time. When programming
the unit via Crimson, a Windows
®
based program, the RS232 or RS485 Cards
must be used.
*Units available in various connector configurations.
SETPOINT CARDS (PAXCDS)
The MPAX series has four setpoint alarm output plug-in cards. Only one of
these cards can be installed at a time. (Logic state of the outputs can be reversed
in the programming.) These plug-in cards include:
PAXCDS10 - Dual Relay, FORM-C, Normally open & closed
PAXCDS20 - Quad Relay, FORM-A, Normally open only
PAXCDS30 - Isolated quad sinking NPN open collector
PAXCDS40 - Isolated quad sourcing PNP open collector
LINEAR DC OUTPUT (PAXCDL)
Either a 0(4)-20 mA or 0-10 V retransmitted linear DC output is available
from the analog output plug-in card. The programmable output low and high
scaling can be based on the input, max, min, or total display value. Reverse
slope output is possible by reversing the scaling point positions.
PAXCDL10 - Retransmitted Analog Output Card
UNITS LABEL (LX)
The LPAX Display has an area on the front panel designed for a custom units
label. The units label is applied directly to the panel in the embossed area. The
units backlight is then turned on via programming.
Refer to the LPAX Accessories Bulletin for a list of available units labels.
PROGRAMMING SOFTWARE
Crimson 2 (SFCRD2) is a Windows
®
based program for configuring and
updating the firmware of the MPAXDP meter from a PC. Using Crimson 2
makes programming the MPAXDP meter easier and allows the user to save the
MPAXDP database in a PC file for future use. Crimson is available as a free
download from Red Lion’s website, or it can be purchased on CD.
The first time Crimson 2 is run from the File menu, select “New” to display
a dialog and select the MPAXDP. The screen will display icons that represent
the various programming sections of the MPAXDP. Double-click on an icon to
configure the programming parameters pertaining to the selection. Tool Tip help
is available for each of the program parameters. A PAX serial plug-in card is
required to program the meter using the software.

OPTIONAL PLUG-IN CARDS AND ACCESSORIES
About the MPAX Input Modules
The MPAX Module serves as the input to the LPAX Display. The MPAX module provides input scaling which allows the LPAX to display most any engineering
unit. Once the MPAX is inserted into the LPAX, the unit has the same functions and capabilities of our PAX Series Intelligent Panel Meters. A full set of PAX
programming instructions will be included with the MPAX Module.
Note: The MPAX provides the operating power for the LPAX, therefore you must select either the AC or DC MPAX corresponding with your application and available
power.
Selecting Your Display Components
To build a complete display unit, you will need an LPAXDP and an MPAXDP Input Module. The LPAX is only a display and will not operate without an MPAX
Module. Please use the following chart to identify the appropriate MPAX Module (including supply power) and LPAX Display that will satisfy your application.
