Displays voltage for each phase, frequency,
phase rotation and voltage unbalance for both
normal and emergency sources.
Provides voltage and frequency setting values for
normal and emergency sources. Voltage pick-up,
dropout and trip settings are set in percentage of nominal
voltage and are also displayed in rms voltage values.
Seven independent programs, load/no load
selection, flexible run times and daily, weekly,
bi-weekly and monthly exercise routines.
Active time delay status displays time
remaining until next control event.

Provides direct reading display for setting time delays.
Displays system status in clear, concise language.
Message shown indicates normal source is acceptable
and the load is connected to the normal source.
Displays detailed information for last 99 events,
including time of occurrence, length of event,

the controller is awaiting an inphase condition.
Shed Load
Direction: From E
Inphase: No TD/0.25
Standard features can be activated with the keypad. As an
example, when enabled, the “shed load” option causes the
transfer switch to transfer the load off of the specified source.
If desired, the load shed transfer can be made inphase.
