WARNING: Disconnect all power to the unit before

installing plug-in cards.

Adding Option Cards

The PAX2D meters can be fitted with up to three optional plug-in cards. The

details for each plug-in card can be reviewed in the specification section below.

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 plug-in cards can be installed initially or at a

later date.

COMMUNICATION CARDS (PAXCDC)

A variety of communication protocols are available for the PAX2D meter.

Only one PAXCDC card can be installed at a time. Note: For Modbus

communications use RS485 Communications Output Card and configure

communication (tYPE) parameter for Modbus.

PAXCDC10 - RS485 Serial (Terminal) PAXCDC30 - DeviceNet

PROGRAMMING SOFTWARE

Crimson

software is a Windows

based program that allows configuration

of the PAX

meter from a PC. Crimson offers standard drop-down menu

commands, that make it easy to program the meter. The meter’s program can

then be saved in a PC file for future use. Crimson can be downloaded at www.

SETPOINT CARDS (PAXCDS)

The PAX2D meter has 4 available setpoint alarm output plug-in cards. Only

one PAXCDS card 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

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 various display values. Reverse slope output is possible

by reversing the scaling point positions.
