Time Delay Emergency Fail (TDEF)
This feature provides a time delay that prevents a connected
Generator power source from being declared “Failed” in order
to override momentary generator fluctuations. If the Genera-
tor power source remains in the failed state then, 0.5 sec-
onds after the TDEF timer expires, the transfer switch will
proceed with the programmed sequence for retransfer.
Fixed at 6 Seconds
12. Power Source Annunciation
This feature provides LEDs to give switch position and power
source availability indications.
Switch Position
Provides LEDs to indicate the switch position
12C. Utility - Source Connected
This feature provides a green LED that, when lit, indicates
the load is connected to the Utility.
12D. Generator - Source Connected
This feature provides a red LED that, when lit, indicates the
load is connected to Generator.
Power Source Availability
Provides LEDs to indicate if a power source is available.
LEDs may be integral or separate from the controller.
12G. Utility - Available
This feature provides a white LED that, when lit, indicates
the Utility is available.
12H. Generator - Available
This feature provides an amber LED that, when lit, indicates
the generator is available.
23.
Generator Test
This feature provides a means for automatic testing of the
engine generator set or standby power system. All pro-
grammed time delays will be performed during plant exer-
ciser operations.
23A. Generator Test Selectable – Off 7/14/28 Day Interval
This feature provides for automatic test operation of the
generator. Available test cycles are 7, 14, or 28 days with
a 15-minute duration.
Programmable setpoints allow for selection of three test
cycles:
•
Generator Start/Run Only (No Load);
•
Generator Test with Load Transfer; or
•
Disabled
This is a “Failsafe” operation.
26.
Utility - Monitoring and Protection
This feature provides Utility monitoring and protection func-
tions. If the Utility power supply fails, then the
ATC 100 will begin the sequence of operations necessary
to transfer the load circuit to the Generator power supply.
All Feature 26 monitoring and protection functions are Fail-
safe operations.
26P. All Phase Undervoltage Protection
Adjustable Undervoltage:
Dropout: 80% of nominal
Pickup: 90% of nominal
3.4.2 Optional Features
The following is a list of the optional features for the ATC-100
Controlled ATS.
All features or combinations of features may not
be available on specific ATSs
14. Relay Auxiliary Contacts
14G. Utility Present:
Provides two (2) normally open and two (2)
normally closed contacts. The relay is energized when the
Utility is available.
14H. Generator Present:
Provides two (2) normally open and two
(2) normally closed contacts. The relay is energized when
the Generator is available.
15. Switch Position Indication Contact
This feature provides a contact that indicates if the power
switching device is in the “Open” or “Closed” position.
15E. Utility Position Indication Contact
This feature provides 1 dry form “C” contact that indicates
the position of the Utility power switching device.
15F. Generator Position Indication Contact
This feature provides 1 dry form “C” contact that indicates
the position of the Generator power switching device.
38.
Stainless Steel Logic Cover
38C. SS ATC-100 Cover
This feature provides a pad-lockable stainless steel cover for
the ATC-100 Controller.
3.5 Optional Features
The following is a list of optional features for the ATS.
15.
Switch Position Indication Contact
Provides a contact that indicates if the power switching
device is in the “Open” or “Closed” position.
15M. Load Shed
Four sets of contacts are available and can be used to con-
trol large connected loads on the generator (i.e. air condi-
tioners, hot tubs, etc.).
16.
Integral Overcurrent Protection
Provides thermal-magnetic overcurrent protection integral to
the power switching device(s). All Feature 16 options
include a “Lockout” function. If the power switching breaker
trips on an overcurrent condition then “Lockout” is displayed
on the Automatic Transfer Controller display and automatic
operation is prevented until the appropriate source is manu-
ally reset. On non-automatic switches, a blue light is sup-
plied to indicate the “Lockout”.
16S. External Overcurrent Protection on the Utility Power Switch-
ing Device
Provides overcurrent protection on the Utility power switch-
ing device.
