CPUM 200-595-079-531 Modular CPU Card

Functional Description

The CPUM is a modular central processing unit (CPU) card intended for use in the machinery protection

system and condition monitoring system racks from Sensing Systems product line. Depending on the system

requirements, the CPUM can be used alone in the rack (installed in the front card cage) or in conjunction

with the associated IOCN input/output card (installed in slot 0 of the rear card cage, directly behind the

CPUM).

The CPUM front panel features an LCD display that shows the level of a selected monitored output in

bargraph and digital form, with the Alert and Danger levels also indicated on the bar-graph. The signal

identification (slot and output number) is shown at the top of the display.

The SLOT and OUT (output) keys on the front panel are used to select which signal to display. The ALARM

RESET button on the front panel resets all latched alarms (and associated relays) for the entire rack.

LEDs on the front panel indicate the OK, Alert (A) and Danger (D) status for the currently selected signal.

When Slot 0 is selected, the LEDs indicate the overall status of the whole rack. When the DIAG (diagnostic)

LED shows green continuously, the CPUM card is operating normally, and when the DIAG LED blinks,

the CPUM card is operating normally but access to the CPUM card is restricted due to MPS rack (CPUM)

security.
