CONTREX CX-1200 - Manual (Page 323)

8 - 26
DEVICE STATUS P1/2
The Device Status screen displays the microprocessor related faults. Norm Pwr Ups (MP-154) indicates
how many times power has been applied to the CX-1200 since the last “Clear-7” power-up. The Low Pwr
Cntr (MP-155) shows the number of times the CX-1200 experienced low power before shutting down. If
this number is greater than Norm Pwr Ups (MP-154), it can indicate that the line-power input has dipped
below about 100 volts AC. However, this could also indicate that a “Clear-7” power-up was executed and
the Low Pwr had not been reset. Therefore, it is important to reset the Low Pwr Cntr (MP-155) after a
“Clear-7” power-up, to keep the numbers accurate. Use Clr Fault Cntrs (CP-491) to reset the Low Pwr
Cntr (MP-155).
Last Reset
Last Reset (MP-150) displays a “1” in a bit to indicate the reason for the last reset. Refer to Appendices: Appendix C
for the Last Reset (MP-150) bit map list. The Help screen for Last Reset (MP-150) also contains a bit map list.
Misc Intrpt
Miscellaneous Interrupts (MP-151) displays a “1” in a bit to indicate which of the various system interrupts may have
caused the last reset. Refer to Appendices: Appendix C for the Misc Intrpt (MP-151) bit map list. The Help screen for
Misc Intrpt (MP-151) also contains a bit map list.
Device Alms
Device Alarms (MP-152) displays the status of microprocessor or other hardware related alarms. Notification of a bad
block selection is also included. Refer to Appendices: Appendix C for the Device Alarms (MP-152) bit map list. The
Help screen for Device Alarms (MP-152) also contains a bit map list.
Norm Pwr Ups
Normal Power Ups (MP-154) displays the number of normal power-ups since the most recent “Clear-7” power-up . This
value is reset only by a “Clear-7” power-up. Norm Pwr Ups (MP-154) is used primarily for troubleshooting.
Low Pwr Cntr
Low Power Counter (MP-155) displays the number of low power detections, including normal “Power Downs”. You
can reset this numeric value, but only in Clr Fault Cntrs (CP-491). Low Pwr Cntr (MP-155) is used primarily for
troubleshooting.
Mem Err Cntr
Memory Error Counter (MP-156) displays the number of memory test failures that occurred during “Power Up”. You
can reset this numeric value, but only in Clr Fault Cntrs (CP-491). Mem Err Cntr (MP-156) is used primarily for
troubleshooting.
WatchDogCntr
Watch Dog Counter (MP-157) displays the number of watch dog resets that were caused by Watchdog time-out.
WatchDogCntr (MP-157) is used primarily for in troubleshooting. You can reset this numeric value, but only in ‘Clr
Fault Cntrs’ (CP-491).
Clr Fault Cntrs
To reset all the system-fault counters except Norm Pwr Ups (MP-154), enter a “1” in Clear Fault Counters (CP-491). The
