8-6 CENTRON Meter Technical Reference Guide
Non-fatal errors can be programmed to scroll during the one second display off-
time or lock on the register display. If multiple non-fatal errors occur, the meter
will display a combined error message. For example, if a low battery error and a
clock error exist, the error display will read ER 010001. In this case, if one of the
errors had been programmed to lock, and the other error had been programmed to
scroll, the display will lock on the combined error message.
Activating the Alternate Mode Magnetic Reed Switch allows the Normal Mode
Display Sequence to scroll one time during a locked non-fatal error. At the end of
the display sequence, the error message locks onto the display again.
Non-Fatal Error Codes
Table 8.3 Non-Fatal Error Codes
Code Error Possible Causes
Er 000001 Low Battery Error
Number of minutes on the battery has exceeded one year-
replace module—checked on power up and once per second.
Discussion:
A low battery check is performed once every second. If a low battery level is detected
during this procedure, error code Er 000001 is displayed in Normal mode. This error can
be programmed to continuously scroll during the one second display off-time or lock on
the register display. A low battery continues to function; however, its reliability decreases
over time.
If a low battery level error occurs during normal operation, TOU and Mass Memory will
continue to operate until an outage occurs. If a low battery level is detected upon
programming or upon restoration of power after an outage, ER 000001 will display. Total
registers remain functional during a Low Battery Condition; however, TOU (rates A, B,
C, D) registers and load profile will not accumulate.
Er 007000
Reverse Direction
Error
Reverse Direction Error Indicator—Clear on demand reset or
reprogram register; checked continuously.
Discussion:
A Reverse Direction error exists when the register detects 10 Wh in the reverse
direction. Reverse Direction detection is a selected feature during programming. If a
Reverse Direction error occurs, Er 007000 is displayed during the one second off-time
in Normal mode.
The Reverse Direction error will clear when a demand reset is performed.
Er 010000 Clock Error
Clock Error—Reprogram register and check for proper
operation; checked upon programming and once per second
Discussion:
A Clock error exists when a clock parameter is determined to be out of range. If this
error occurs, Er 010000 is displayed in Normal mode. This error is programmable to
continuously scroll during the one second display off-time or lock on the register display.
If a Clock error occurs, the Load Profile and TOU operations will be discontinued until
the meter is reprogrammed. The error will then clear, and the meter will resume normal
operation.
Er 020000 TOU Error
TOU Error—Reprogram register and check for proper
operation; checked upon programming and once per second
Discussion:
A TOU error occurs when the TOU calendar is out of range. TOU is disabled.
Er 030000 Load Profile Error
Load Profile Error—Reprogram register and check for proper
operation; checked upon programming and once per second
