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.
Available on 5-digit version only. Refer to the LPAX Accessories Bulletin for
a list of available units labels.
PROGRAMMING SOFTWARE (CRIMSON)
Crimson is a Windows
®
based program that allows configuration of the
LPAX meter from a PC. Crimson offers standard drop-down menu commands,
that make it easy to program the LPAX meter. The LPAX program can then be
saved in a PC file for future use. 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. There are several different modules to cover a variety of inputs. 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 LPAX and an MPAX 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.
