2.6.3 Microprocessor Component Description

And Location

The microprocessor controller consists of two modules

-- the control module (See Figure 2-7) and display and

keypad module (See Figure 2-8). The control module is

housed in the control box on the lower roadside (right)

corner of the unit. This control module consists of a logic

board and an input/output board. The control module

contains externally accessible relays and fuses. The

display and keypad module is located for driver access

at the lower roadside corner of the unit.

The processor board in the control module includes the

microprocessor, program memory and necessary

input/output circuitry to interface with the unit. The

microprocessor is totally self contained and does not

contain any serviceable components.

The display board is mounted in the keypad and display

module. The board includes the LCD display, keypad

and keypad interface.
The keypad & display module provides the user with a

panel to view and control the functions of the

refrigeration unit. The module consists of a switch,

keypad, MessageCenter, and Main Display. Setpoints

and other system information are selected using the

keypad.

Figure 2-8 shows the display & keypad

module.

CAUTION

Under no circumstances should anyone attempt to repair the Logic or Display Boards. Should a

problem develop with either of these components, contact your nearest Carrier Transicold dealer for

replacement.

a. Control Module

Figure 2-7 shows the Control Module. The Control

Module has 3 relays and 4 fuses that are user

accessible.

The PC card slot is also shown in Figure 2-7. This card

slot is used with all Carrier Transicold PC Cards. The

controller automatically detects the presence and type

of PC Card inserted and responds accordingly. The

different types of PC Cards are:

Download Card for copying unit data from Data

Recorder.

Options PC Card for installing optional software

programs

Configuration PC Card for setting the Microprocessor

Functions,

Configurations

and

Data

Recorder

configurations.

Program PC Card for upgrading the microprocessor

software.

There are three LEDs associated with the function of the

PC card slot. These are:

•

A green Micro Status LED which will blink steadily once

per second indicating that the microprocessor is

operating and will blink every 0.5 seconds if there is no

software or if it is loading software.

•

A green (PC) Card Status LED which comes on when

there is a PC card inserted in the slot. This LED will:
1. Blink every 0.5 seconds when data is being trans-

ferred to or from the PC Card, and Will be on steady

when the operation is complete and the PC Card

may be removed.

2. During Download, the light will blink once per second

and will blink every 1.5 seconds when the Download

is complete.

•

A red (PC) Card Fault LED blinks if there is a problem

transferring data from the PC card that has been

plugged into the PC card slot. The red LED will continue

to blink until the PC card is removed. The LED will also

blink if there is an error reading the card. Check the

MessageCenter for description of error.
