XR Series models have extensive diagnostic functions -- all of which when activated take

command to shut down the system. Diagnostic functions include phase loss, excessive thermal

conditions, over voltage trip, over current trip, and program line. Program line monitors

externally applied analog set point signals to insure they are within the specified range. Upon a

diagnostic fault condition, main power is disconnected and the diagnostic condition is latched

into memory. Pressing the clear key clears the memory. All diagnostic functions can be

monitored through a rear connector. Furthermore, control functions can also be set through the

rear connector to allow simultaneous control of one or more XR Series units.

1.4 Power Requirements

XR Series power supplies are manufactured to operate on 208/240 V, 380/415 V, or 440/480 V

50 to 400 Hz mains.

The standard operating voltage is 208 V, 3φ, 50 to 400 Hz unless otherwise specified at time of

order. For conversion from 208 V to 240 V operation, two internal wiring changes must be

made. The locations are not accessible to the user and the power supply must be returned to the

factory for modification.

XR Series power supplies are optionally available to operate on 380 V or 480 V, 3φ, 50 to 400

Hz mains. For conversion from 380 V to 415 V or from 480 V to 440 V operation, two internal

wiring changes must be made. The locations are not accessible to the user and the power supply

must be returned to the factory for modification.
