Figure 4. Software and Options Identification Display
Note:
The entire Figure 4 message is shown for clarity, in actuality the message scrolls across the display as space permits.
3.3 Pushbuttons
The front operations panel supports six blue membrane pushbut-
tons. Pushbuttons accomplish their function when pressed and
released. Certain pushbuttons, like the Increase and Decrease
Pushbuttons, will also continue to scroll if they are pressed and
not released. The Run/Program Switch, located on the right rear
chassis, is not a membrane pushbutton. It will, however, be
addressed in this section since it is required to move between the
Run and Program Modes.
3.3.1 Run/Program Toggle Switch
The right rear mounted Run/Program Toggle Switch establishes
whether the ATC-800 is in the Run Mode or the Program Mode.
Normally the switch is set in the Run position to permit normal
programmed operations. Programmed setpoints can only be
altered with the switch in the Program position. Altered setpoints
are stored and establish the new operating conditions of the ATC-
800 only after the switch is moved back to the Run position.
3.3.2 Help Pushbutton
When the Help Pushbutton is pressed and released with the
ATC-800 in any mode, an English language message will scroll
across the display. Pushing and releasing the pushbutton a second
time will abort the message. Messages and explanations relative
to what is being viewed in the display are intended to prompt and
assist the operator.
3.3.3 Engine Test Pushbutton
When the Engine Test Pushbutton is pressed twice and released
with the ATC-800 in the status state, a self-test is initiated. This
test can be initiated and accomplished while in the Run or Program
Modes. Pressing the Engine Test Pushbutton again while in the
engine run condition aborts the test.
Upon test initiation, a generator start of the non-preferred source is
engaged after TDES timeout. If a full test is programmed, a transfer
with all programmed timers occurs. The test engine run timer will
hold the load for the required timeout and the test is concluded with
a re-transfer cycle. For an engine run only test, no transfer will occur
and the engine will run for the programmed run time.
3.3.4 Display Select Pushbutton
As the Display Select Pushbutton is pressed and released, ATC-
800 steps through the following display categories:
•
Status
•
Source 1
•
Source 2
•
Load
•
History
•
Time
•
Date
•
Setpoints
3.3.5 Step Pushbutton
The Step Pushbutton steps through the different available infor-
mation within the display category selected as the pushbutton is
pressed and released.
When Source 1 is the category displayed for example, use of the
Step Pushbutton will step the display through the voltages, fre-
quency and status condition associated with Source 1. In the
Time/Date category, however, this pushbutton has an additional
purpose. The Step Pushbutton is also used to permit programming
of the time and date by stepping through the different time and
date categories (Hours, Minutes, Month, Day and Year). The
actual time or date category is moved up or down using the
Decrease or Increase Pushbuttons described next.
3.3.6 Increase and Decrease Pushbuttons
These pushbuttons, when pressed and released for step by step
changes or held depressed for scrolling, increase or decrease set-
points while in the Programming Mode or make Time/Date changes.
While historical information is being displayed, the Increase Pushbut-
ton will scroll through events, and the Decrease Pushbutton will
scroll through the actual time and date of the event. In addition, if
both buttons are pressed and released simultaneously while viewing
any of the historical logged values, the value resets to zero. Refer to
paragraph 3.4.4 and Appendix B for additional information pertaining
to accessing historical information and historical data definitions.
Simultaneously pressing and releasing the Increase and Decrease
Pushbuttons will also reset an alarm condition.
NOTICE
PRESSING AND RELEASING THE HELP PUSHBUTTON WITH THE
ATC-800 DISPLAY WINDOW BLANK CAUSES ALL OF THE FRONT
PANEL LEDS TO MOMENTARILY LIGHT BEFORE SCROLLING A MES-
SAGE ACROSS THE DISPLAY (FIGURE 4). THE MESSAGE INDICATES
THE SOFTWARE VERSION, REVISION NUMBER, AND AN ENCODED
CATALOG NUMBER THAT REVEALS TO EATON WHAT SPECIFIC
OPTIONS ARE INCLUDED WITH THIS PARTICULAR UNIT. THE CUS-
TOMER MAY BE ASKED FOR THIS INFORMATION BY EATON DUR-
ING A TROUBLESHOOTING OR RETURN PROCESS.
NOTICE
THE OPTIONAL PLANT EXERCISER FEATURE ALLOWS FOR AUTO-
MATIC PROGRAMMING OF THE DESIRED TEST CYCLE ON A
WEEKLY BASIS. IF THE SWITCH IS UNABLE TO PROCESS EITHER A
PLANT EXERCISER REQUEST OR THE ENGINE TEST PUSHBUTTON
ITSELF DUE TO TRANSFER SWITCH STATUS, THE REQUEST IS
IGNORED.
