MultiFlex PAK Overview of the MultiFlex Product Line • 1

1 Overview of the Multi-

Flex Product Line

The MultiFlex line of control system boards

provides a wide variety of input, output, and

smart control solutions, all of which are based on

a single universal hardware platform. The board

design uses flash-uploadable firmware and plug-

in expansion boards to configure the base plat-

form board and apply it for use as an input

board, relay output board, analog output board,

or a combination I/O board.

1.1. MultiFlex PAK

The PAK is a distributed pack controller that

controls compressors and condenser fans. The

PAK can control up to 16 compressors, con-

trolled in up to 8 compressor groups.

The PAK can control up to 4 condenser fan

groups containing up to 8 total condenser fans.

The PAK condenser control strategy is sequen-

tial TD control with setpoint/deadband using ON

and OFF delays. The PAK supports use of both

single-speed fan stages and VS fans.

1.1.1. Hardware

The MultiFlex PAK boards consist of two

circuit boards: a bottom layer with 16 combina-

tion digital/analog inputs, and a plug-in top layer

which contains a combination of 8 relay outputs

and 4 analog DC voltage outputs, which can be

used as digital or analog outputs.

The communication interface is RS485 I/O

using the Standard Extended Address Form for

CPC Distributed Controllers. Currently, the PAK

is designed to interface with the CPC E2 RX

controller, and the previous generation refrigera-

tion controller, the Einstein RX.

2 Mounting and Power-

ing

The MultiFlex boards are usually installed

by the refrigeration or building equipment man-

ufacturer. Therefore, the installer need only

make the necessary connections between the

boards and the site controller(s).

In some instances, an installer may be

required to mount an I/O board. There are no

restrictions on the location of these boards; how-

ever, for ease of network configuration, it is rec-

ommended that the boards be located adjacent to

the E2. I/O boards may be mounted without an

enclosure, but they should be mounted in a loca-

tion that is not easily accessible to avoid tamper-

ing or damage.

2.1. Snap-Track Installation

MultiFlex boards not supplied in a custom

panel or other enclosure are supplied with a

snap-track for easy installation. The insulation

sheet and I/O board must be removed from the

track before the track is mounted. The snap-track

is mounted using the 0.1875” mounting slots.

Figure 2-1 shows this installation procedure.

Figure 2-2 provides mounting dimensions

for the MultiFlex board.
