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 occurance, length of event, date and reason for event.

Displays the relative phase angle between sources, the
frequency difference and voltage differential to indicate 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.
