MPE XR III series, Operator'S Manual

Page: 16 / 129

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, 3 φ , 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, 3 φ , 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.
