The 7000 Series microprocessor controller is a Transfer Control Center
which allows the user to easily access detailed information on: system
status; power source parameters; voltage, frequency and time delay settings;
optional feature settings; historical event log; and system diagnostics. A four
line, (20) character LCD has a backlit display which enables easy viewing
under all conditions. The user can navigate through all screens using only
six buttons, which also allows selection of: (18) different source parameter
settings; (16) standard time delays; (12) standard feature settings; up to
seven independent engine exercise routines; and even the language
(English, German, Spanish, French, etc.) which appears on the display.
Since the Transfer Control Center must be visible and operable through
the enclosure door, it has been qualified for use in industrial and outdoor
applications. This includes installation in Type 3R (outdoor/rainproof),
4 (weatherproof) and 12 (indoor/industrial) enclosures.

• Switch position indicating lights (16 mm, industrial grade LEDs).
• Source acceptability indicating lights with true indication of the
acceptability of each source, as determined by the voltage, frequency,
voltage unbalance, and phase sequence settings of the control panel
(16mm, industrial grade LEDs).
• Three position (16mm, industrial grade type) selector switch:
• Automatic: Normal maintained position.
• Test: Momentary position to simulate normal source failure for
system test function.
• Reset Delay Bypass: Momentary position to bypass transfer and
re-transfer time delay.
• Extended Parallel Time - Provides visual indication when the
pre-set extended parallel time has been exceeded. The controls
automatically open the emergency or normal main contacts.
Separate contact also available to shunt trip external breaker.
• Failure To Synchronize - Visually displays a failure to synchronize
alarm if the time delay settings is exceeded, during closed
transition transfer operation.
• TS Locked Out - Prevents transfer in either direction if the
extended parallel time is exceeded.
• Alarm Reset - Resets extended parallel and failure to
synchronize alarms.
• Closed Transition Bypass - Pushbutton allows transfer
between sources in an open transition mode.
