Features and benefits

Digital timer and adjustments with 1 second resolution
Long lasting LED indicators and an easy-to-view LCD display
Inputs optoisolated for high electrical immunity to transients and noise
Digital voltage and frequency adjustments with1% resolution
Voltage and frequency sensing includes:
–Voltage imbalance detection between phases
–Under frequency sensing on source 2
–3 Phase under voltage sensing on source 1(S1)
– Normal and single phase sensing onsource (S2)
– Emergency
Modular pre-signal option easily integrated into the system (e.g. elevator pre-signal and motor load disconnect)
Universal Motor Disconnect (UMD) available for programming to pre-signal, post-signal or both
Line voltage transients are isolated from the control board using remote transformers
Simplified major components and modules for easy replacement
On-board diagnostics including voltage frequency, control and timing
Nonvolatile memory – battery backup not required during normal source outage
External communication available through LonWorks/ModBus network interface (RS232,RS 422, and RS 485 are also available)
Maintained and momentary test positions are available to the controller
Test mode allows manual bypass of all transfer timers when applicable
Automatic daylight savings adjustment available

User-friendly operation

LEDs for continuous monitoring of switch position, source availability, exercise time delay operation and diagnostics
Simplified adjustment for voltage, frequency and time delay settings
Close differential 3 phase under-voltage sensing of source 1, factory standard setting 90% pickup,80% dropout (adjustable); under-frequency sensing of the source 1 factory setting 95% pickup (adjustable)
Voltage and frequency sensing of source 2,factory standard setting 90% pickup voltage,95% pickup frequency (adjustable)
Test switch (fast test/load/no load) to simulate normal source failure – automatically bypassed should source 2 fail
