Commonly Used Accessories
Standard Accessories
D Controller contains a CMOS microprocessor and nonvolatile
memory.
D Microprocessor provides digital accuracy for time-delay,
source-transfer, and generator set exerciser intervals.
D Controller is protected against EMI,voltage transients, ESD,
shock, vibration, and other hostile environments per U.S.A.,
Canadian, and IEC standards.
D All printed circuit boards are conformal coated for
environmental protection.
D Transfer switches with microprocessor logic have area
protection with override.
D The normal source voltage is monitored across live lines of
single-phase switches, and all phases of normal source are
monitored line-to-line on three-phase switches.
D Theemergency source voltageandfrequency aremonitored
across one phase.
D User-adjustable time delays include: Normal to Emergency
(TDNE), Engine Start (TDES), Emergency to Normal
(TDEN), Engine Cooldown (TDEC), Off to Emergency
(TDOE), and Off to Normal (TDON).
D Each microprocessor-controlledtransferswitchwith aNEMA
type 1 enclosure has a front-accessible status panel.
D An LCD display, touch key pad, and LED indicating lights
allow user interaction with the controller.
D Generator set exercising intervals can be selected from
seven-day, fourteen-day, or calendar settings.
D The test switch simulates a normal source power failure.
D Ambienttemperaturerange: Operating-20_ Fto+150_ F,
±2% accuracy
Storage-60_Fto+220_F
D Transfer Switch Humidity: 0 to 100% noncondensing,
operatingandstorage.
