ABB IRC5 power supply DSQC328A robot main computer board

Description

TRANSFORMER DE-ENERGIZED: The Transformer De-Energized LED indicator is on

when the energization inhibit feature has detected that the transformer is de

energized. The indicator is on if the Energization Inhibit feature is detecting the

transformer as de-energized

TRANSFORMER OVERLOAD: The Transformer Overload LED indicator is on when the

Transformer Overload element has operated.

LOAD-LIMIT REDUCED: The Load-Limit Reduced LED indicator is on when the

adaptive harmonic factor correction feature is detecting enough harmonic content to

reduce the load rating of the transformer. The indicator is on if S2 SYSTEM SETUP 

HARMONICS  HARMONIC DERATING ESTIMATION is “Enabled” and the harmonic

derating function is below 0.96.

SETPOINT GROUP 1(4): These indicators reflect the currently active setpoint group.

The indicators flash when the corresponding setpoint group is being edited.

4.1.4.3 Output Status Indicators

TRIP: The Trip LED is on when any output relay selected to be of the Trip type has

operated.

ALARM: The Alarm LED is on when any output relay selected to be of the Alarm type

has operated.

PICKUP: The Pickup LED is on when any element has picked up. With this indicator on,

the front panel display is sequentially displaying information about each element that

has picked up.

PHASE A (C): The Phase A(C) LEDs are on when phase A(C) is involved in the condition

detected by any element that has picked up, operated, or is now in a latched state

waiting to be reset.

Ground: The Ground LED is on when ground is involved in the condition detected by

any element that has picked up, operated, or is now in a latched state waiting to be

reset.

Use the front panel program port for RS232 communications with the 745. As described in

RS232 Front Panel Program Port on page 3–19, all that is required is a connection between

the relay and a computer running EnerVista 745 Setup. For continuous monitoring of

multiple relays, use the COM1 RS485/RS422 port or the COM2 RS485 port.

4.1.6 Keypad

4.1.6.1 Description

The 745 display messages are organized into main menus, pages, and sub-pages. There

are three main menus labeled setpoints, actual values, and target messages.

Pressing the MENU key followed by the MESSAGE DOWN key scrolls through the three main

menu headers, which appear in sequence as follows:

Pressing the MESSAGE RIGHT or ENTER key from these main menu pages will display the

corresponding menu page. Use the MESSAGE keys to scroll through the page headers.

When the display shows SETPOINTS, pressing the MESSAGE RIGHT or ENTER key will display

the page headers of programmable parameters (referred to as setpoints in the manual).

When the display shows ACTUAL VALUES, pressing the MESSAGE RIGHT or ENTER key

displays the page headers of measured parameters (referred to as actual values in the

manual). When the display shows TARGET MESSAGES, pressing the MESSAGE RIGHT or

ENTER key displays the page headers of event messages or alarm conditions.

Each page is broken down further into logical sub-pages. The MESSAGE keys are used to

navigate through the sub-pages. A summary of the setpoints and actual values can be

found in the chapters 5 and 6, respectively.

The ENTER key is dual purpose. It is used to enter the sub-pages and to store altered

setpoint values into memory to complete the change. The MESSAGE RIGHT key can also be

used to enter sub-pages but not to store altered setpoints.

The ESCAPE key is also dual purpose. It is used to exit the sub-pages and to cancel a

setpoint change. The MESSAGE LEFT key can also be used to exit sub-pages and to cancel

setpoint changes.

The VALUE keys are used to scroll through the possible choices of an enumerated setpoint.

They also decrement and increment numerical setpoints. Numerical setpoints may also be

entered through the numeric keypad.

The RESET key resets any latched conditions that are not presently active. This includes

resetting latched output relays, latched Trip LEDs, breaker operation failure, and trip coil

failure.
