NOTICE
IF THE ATS IS UNABLE TO PROCESS A ENGINE TEST REQUEST
DUE TO THE ATS STATUS, THE REQUEST IS IGNORED.
When the Engine Test pushbutton is pressed, the following
message will appear on the LCD Display:
Line 1: Password 0 0 0 0
Line 2: Use Inc/Dec & Step
After entering the 4-digit password and pressing the Step/
Enter pushbutton, the ATC-300 will display the Time Delay
on Engine Starting (TDES) timer countdown. Once the TDES
countdown reaches zero, the ATC-300 Controller will initiate
an engine start. The engine run duration will be per the
Engine Run Test Time setpoint.
If the (0) No Load Engine Test Mode has been selected, the
transfer from Source 1 to Source 2 will not occur. If the
(1) Load Engine Test Mode has been selected, the transfer
from Source 1 to Source 2 will occur after the generator out-
put has reached the specified setpoints. If the (2) Disabled
Mode has been selected, or if the "Number of Generators"
setpoint is programmed to zero, the Engine Test will not
occur.
All enabled and programmed time delays will be performed
per the setpoints during an engine test. The time delays will
appear on the LCD Display with "countdown to zero" when
active. Depending on the setpoints and the optional features
selected with the ATC-300 Controller, these can include:
TDES;
Time Delay Normal to Emergency (TDNE);
Time Delay Emergency to Normal (TDEN);
Time Delay for Engine Cooldown (TDEC);
Time Delay Neutral (TDN); and
Pre-transfer Delay Signal (TD PRE-TRAN).
All operations are "Failsafe", that is they prevent disconnec-
tion from the only available power source and also force a
transfer or re-transfer operation to the only available power
source.
During an engine test, if the Engine Test pushbutton is
pressed a second time before the Engine Test is complete and
correct password has been entered; the Engine Test will be
terminated. An engine test may also be aborted in the follow-
ing ways:
1. If the Emergency Source does not become available
within 90 seconds of the ATC-300 providing the engine
start command;
2. If, during the TDNE countdown, the Emergency Source
goes unavailable more than three times (Each time, TDNE
will restart);
3. If the Emergency Source is powering the load and it goes
unavailable for more than the TDEF setting; and
4. If the Normal source becomes unavailable.
When an engine test is aborted due to an unavailable source
during TDNE countdown, the Alarm relay will energize, a
"TEST ABORTED" message with appear on the display, and
the event will be logged into the Transfer History as "Aborted
Test".

5.8 Plant Exerciser
THE PLANT EXERCISER FEATURE ALLOWS FOR AUTOMATIC
PROGRAMMING OF THE DESIRED TEST CYCLE ON A DAILY,
7-DAY, 14-DAY, OR 28-DAY BASIS. IF THE ATS IS UNABLE TO
PROCESS A PLANT EXERCISER REQUEST DUE TO THE ATS STA-
TUS, THE REQUEST IS IGNORED.
The plant exerciser is a feature that provides an automatic
test of the generator. The test can be run daily, every
7 days, every 14 days, or every 28 days with durations equal
to the programmed engine test time. Two optional modes of
plant exercising are available:
The ATC-300 Controller allows the user to program the exact
day, hour, and minute that the Plant Exercise will occur. This
allows for the Plant Exercise to take place at the most oppor-
tune time for the specific facility.
The hour and minute that the Plant Exerciser is performed are
programmed with the "PE HOUR" and "PE MINUTE" setpoints
where "PE HOUR" is in military time (1:00 PM = 13:00) and
the "PE MINUTE" can be set from 0 to 59. The test day is
programmed with the "PE DAY" setpoint. The ATC-300 Con-
troller compares the "PE DAY" setpoint with the "WEEKDAY"
setting, which is set along with the time and date. If a 7-day
plant exercise is programmed, the selections are from
"1 SUN" through "7 SAT".
If a 14-day plant exercise is programmed, the "PE DAY" set-
point can be set from "1 SUN" to "14 SAT" where "1 SUN"
is the first Sunday of the 14-day period and "14 SAT" is the
second Saturday of the 14-day period.
If a 28-day plant exercise is programmed, the "PE DAY" set-
point can be set from "1 SUN" to "28 SAT" where "1 SUN"
is the first Sunday of the 28-day period and "28 SAT" is the
fourth Saturday of the 28-day period.
If desired, the Plant Exerciser can be disabled by choosing
"OFF" for the "Plant Exer-" setpoint.
Plant Exercising in the Load Exercising Mode is "Failsafe". If
the generator fails during testing for any reason, the ATC-300
will signal the transfer switch to return to the Source 1 power
source. The ATC-300 will display "FAILSAFE" until a push-
button is pressed.
5.9 In-phase Transition (Optional Feature 32E)
The In-Phase Transition capability permits a transfer or re-
transfer only between 2 available sources that have a phase
angle difference of eight degrees or less. The In-Phase transi-
tion feature includes user selectable enable/disable and per-
missible frequency difference setpoints. The ATC-300
Controller will display "SYNC TIME" and the active timer on
Line 1 of the LCD display. In the event Source 1 and Source
2 fail to synchronize within the sync time, the Alarm relay will
energize and "Failed to Sync" will be displayed on Line 1.
After resetting the alarm, another in-phase transition may be
attempted or a non-synchronized transfer may be initiated by
failing the connected source. The adjustable frequency differ-
ence is 0.0 to 3.0 Hz.
