Breaker Initiate Features
A built-in solid-state initiate device is used to operate a breaker from the CT-7000 S3.
Operational modes include OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN.
Multiple operation like OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN can be initiated by
using a programmable delay time (in milliseconds) or by sensing a specific breaker contact
condition.
OPEN/CLOSE Coil Current Monitoring
One built-in, hall-effect sensor records the OPEN/CLOSE coil current amplitude and waveform.
The circuit breaker’s coil current waveform, effectively, a coil performance “fingerprint” or
“current profile”, can be used as a diagnostic tool for analyzing the circuit breaker’s
performance.
Computer Interface
The CT-7000 S3 can be computer-controlled via the USB or optional Bluetooth interface.
Windows-based Circuit Breaker Analysis Software is provided with each unit. Using this
software, circuit breakers can be timed from the PC. Test records can be retrieved from the CT-
7000 S3 and then stored on the PC for future analysis and report generation. Circuit breaker
test plans can also be created on the PC and transferred to the CT-7000 S3. Additionally, test
records can be automatically exported in Excel, PDF, and XML formats.
Internal Test Record and Test Plan Storage
The CT-7000 S3 uses Flash memory to store up to 200 test records internally. Test records can
be recalled and printed on the unit's built-in 4.5" wide thermal printer. Test records can also be
transferred to a USB Flash drive or exported to a PC via the USB port or Bluetooth (optional)
with the included Windows-based software. Up to 100 circuit breaker test plans can be stored
in the CT-7000 S3's Flash memory. A test plan is comprised of all circuit breaker performance
specifications (contact time, stroke, velocity, etc.). When a test plan is used with a timing test, a
Pass/Fail report is generated by comparing the actual performance with the specifications in
the stored test plan. Test plans can be transferred to the CT-7000 S3 from a USB Flash drive, or
from a PC via the USB port or Bluetooth (optional).
External Test Record and Test Plan Storage
A USB Flash drive can be used to store and transfer test plans and up to 999 test records.
Built-in Thermal Printer
The CT-7000 S3's built-in 4.5" wide thermal printer can print the breaker contact analysis
results in both tabular and graphic formats.
User Interface
The CT-7000 S3 features a back-lit graphic LCD screen (240 x 128 pixels) that is viewable in
direct sunlight and low-light levels. A rugged 44-key "QWERTY"-style membrane keypad is used
to control the unit and input information.
