Keypad/Display Features

The first line on each page includes the page title and the line

number to which the cursor is currently “pointing.” The line

numbers are X/Y to indicate line number X of a total of Y lines

for that page. The left most position of the title line includes an

“up” arrow to indicate there are pages “above” the currently

displayed items, a “down” arrow to indicate there are pages

“below” the currently displayed items or an “up/down” arrow

to indicate there are pages “above and below” the currently

displayed page. Each line on a page can contain status-only

information or include changeable data fields. When a line

contains status-only information and the cursor is on that line,

all but the value field of that line is highlighted meaning the text

is white with a black box around it. When the line contains a

changeable value and the cursor is at that line, the entire line is

highlighted.

Each line on a page may also be defined as a “jump” line,

meaning pushing the navigation wheel will cause a “jump” to a

new page. An arrow is displayed to the far right of the line to

indicate it is a “jump” line and the entire line is highlighted when

the cursor is on that line.

IM 1005-3 • MICROTECH III REMOTE USER INTERFACE

Troubleshooting

This section contains helpful information, frequently asked

questions, and other tips related to the remote user interface.

General Troubleshooting

During the initial download sequence, the keypad/display

appears to freeze up and a "Loading......Lost Connection"

message appears.

Solution

The remote user interface is stuck in the downloading

sequence due to incompatibility with v1.07 application

software. The remote user interface must be updated

to v10.22 or newer application software. Contact Daikin

Applied Air Technical Response at 844-521-3928 for further

instructions.

Problem

The remote user interface is experiencing a loss of

communication.

Solution

The site may have "dirty power" or electrical noise causing

loss of communication.

1. Access the Power Bus menu on the MicroTech III

unit controller by the following keypad menu path:

service menu/HMI setup/PBusPwrSply=ON (default).

See

Figure 13.

2. Set the default Power Bus supply.

For the first and last units on the daisy-chain

trunk, leave the Power Bus supply at the default

of ON.

b. For all other units within the daisy chain trunk,

set the Power Bus supply to the OFF position.

Figure 13: Power Bus Menu

Problem

The remote user interface has been connected to the

MicroTech III unit controller but the display remains blank

after power-up.

Solution

Verify that the unit controller has power. Check wiring from

the unit controller to the remote user interface.

NOTE:

Inputs and outputs are polarity sensitive.

Frequently Asked Questions

1. Is a separate 24V power supply necessary for direct

connection?

→

No, power is provided by the MicroTech III unit

controller.

2. What type of cable is recommended for daisy-chain

connection?

→ Daikin Applied generally recommends using

twisted

pair, 16 AWG shielded cable up to 500 ft and 14 AWG

from 500 to 1000 ft. Contact the appropriate Technical

Response Center for applications requiring longer

distances.

How do I know if or when I need to upgrade the remote user

interface (HMI) firmware files?

→

If the remote user interface seems to freeze during

initial download process
