1.5.1 User Interface Display (UID)
The User Interface Display (UID), programming set switches and LEDs provide information about the transfer switch, generator and
utility status. This UID is also used for programming the OVATION™ Series ATS for generator size, exercise intervals and other
settings.
1.5.2 Utility and Generator Source Circuit Breakers
Siemens UL489 Listed 10K or 22K AIC utility circuit breakers act as Service Equipment disconnects and source feed wiring protection.
1.5.3 Mechanical Interlocked UTILITY and GENERATOR Main Circuit Breakers and Actuator
NEVER remove the mechanical interlocks/actuators unless the UTILITY or GENERATOR MAIN circuit breakers
require replacement by a qualified service professional. UTILITY or GENERATOR MAIN circuit breakers are mechanically interlocked
to prevent simultaneous UTILITY and GENERATOR power source feeds. Interlocks are automatically moved by a computer controlled
actuator and motor, which may move the circuit breaker handles at any time.
1.5.4 PowerPause™ Load Management Modules (Optional)
Up to 6 connected loads based on parameters set up at installation are actively managed to optimize generator capacity utilization.
As generator power capacity becomes available, the transfer switch will attempt to turn on each load controlled by PowerPause™
Load Management until the generator reaches 85% output utilization. Ideal for seasonal (i.e. air conditioning, pool equipment, etc)
or intermittent (i.e. hot water heater, range, etc) loads. Contact your distributor or Gen/Tran for additional accessories information.
