Status Page
The status page shows the input and output voltages, current and frequency. It is the default page after power
up.
RMS Voltages
V1 = VL1 – VL2
V2 = VL2 – VL3
V3 = VL3 – VL1
System Currents

Frequency,

Note:
When the FSB is closed the current measurement will always be zero. This is because the current transformers are
fitted in the Utility Disconnect. When the FSB is closed the FSB provides the least resistance path so all the
current will flow through the FSB. For load currents below 1.5% the display snaps to zero.
Note:
At no load the current displayed is the combination of coupling transformer magnetizing current and PWM filter
current. This current is mainly capacitive and is generally useful for plants which have a lagging power factor.
The status page of the PCS100 UPS-I in RUN status is shown on Figure 7-3.
The status page of the PCS100 UPS-I in bypass mode is shown on Figure 7-4.
