Redundancy
The PCS100 UPS-I inverter consists of multiple 150 kVA PCS100 inverter modules connected in parallel. If one
inverter module fails the PCS100 UPS-I will reconfigure itself to operate with the remaining modules. A maximum
of 50% of the modules can fail before the PCS100 UPS-I will trip out.
–
Faults that result in a module going offline but remaining connected to the master controller (via
the serial communications CAN bus) are able to be reset. Examples of such faults are Event 55 Sin
Filter Hot and other temperature faults, current trips, voltage trips, power supply trips etc.
–
Faults that result in the module being disconnected from the VCAN bus network are not able to be
reset and will require a Reboot using Parameter
051 System Reboot
. A module can only be
reinstated to the VCAN bus network by rebooting the PCS100 UPS-I. Such faults occur when the
module 27 Vdc power is lost or there is a VCAN bus failure.
–
Faults that result in a module being disconnected from the VCAN bus network are permanently
excluded from the system even if the power is cycled. A reboot must be performed to reinstate such
modules.
