                                                                               2500KW Load Bank System






            The Load Bank is a completely self-
            contained, freestanding unit which
            includes all resistive load elements,
            load control devices, load element
            branch circuit fuse protection, main
            load bus and terminals, cooling system,
            control power supply, unit controller and
            malfunction detection system and type
            enclosure.
            System Protection

            Sensors, alarms (alarm message on
            remote operator interface terminal),
            lock-outs as appropriate, for the
            following:
            •  Fan failure, each of two fans
            •  High exhaust temperature, each of
             two fans
            •  High intake temperature
            •  High interior temperature, sensed at
             three points
            •  Louver open/closed, each of eight
             louvers
