3.1.1 Source 1 and Source 2 Displays
The Source 1 and Source 2 displays indicate the present sta-
tus of the sources in terms of voltage and frequency. If the
source is available, the condition display will be "SOURCE 1
GOOD" or "SOURCE 2 GOOD". If it is unavailable, one of the
following possible conditions will be shown:
SOURCE 1 U-V
The source voltage has dropped below the dropout setting
and not risen above the pickup setting.
SOURCE 1 O-V
IB01602001T
ATC-300 Automatic
Transfer Switch
Controller
SOURCE 2 U-V
SOURCE 2 O-V

Effective: January 2006
The source voltage has risen above the dropout setting and
not dropped below the pickup setting.
SOURCE 1 U-F
The source frequency has dropped below the dropout setting
and not risen above the pickup setting.
SOURCE 1 O-F
The source frequency has risen above the dropout setting and
not dropped below the pickup setting.
SOURCE 1 UNBAL
The voltage unbalance has risen above the dropout setting
and not dropped below the pickup setting.
S1 PHASE REVERSE
The phase sequence does not agree with the setpoint value,
indicating that the phase sequence is reversed.
3.1.2 Time/Date Display
The Time/Date Display indicates real time in terms of hours,
minutes, and seconds; and month, day, and year. It also indi-
cates individual time and date items for programming pur-
poses. The day of the week can also be set with 1 =
Sunday, 2 = Monday, etc. The time, date, and day of the
week can be set in the Program Mode.
3.1.3 History Display
The History Display indicates historical and cumulative
counter values as follows:
Engine Run Time
This counter will log the generator run time in hours. Time
will start being logged at the time the GEN START contacts
are closed, and it will stop as soon as they are opened. This
counter will count up to 9999 hours and then turn over to
0000. It can be reset to zero in the Program Mode.
Source 1 Connected Time
This counter logs the time in hours that Source 1 has been
connected to the load. Time will be logged while the
SOURCE 1 CLOSED control input is in the "connected" state.
This counter will count up to 9999 hours and then turn over
to 0000. It can be reset to zero in the Program Mode.
Source 2 Connected Time
This counter logs the time in hours that Source 2 has been
connected to the load. Time will be logged while the
SOURCE 2 CLOSED control input is in the "connected" state.
This counter will count up to 9999 hours and then turn over
to 0000. It can be reset to zero in the Program Mode.
Source 1 Available Time
When Source 1 meets the voltage and frequency setpoint cri-
teria, this counter logs the time in hours. This counter will
count up to 9999 hours and then turn over to 0000. It can
be reset to zero in the Program Mode.
Source 2 Available Time
When Source 2 meets the voltage and frequency setpoint cri-
teria, this counter logs the time in hours. This counter will
count up to 9999 hours and then turn over to 0000. It can
be reset to zero in the Program Mode.
