Fatal Error Codes - ITRON CENTRON C1SR Technical Reference Manual

CENTRON Meter Technical Reference Guide
Code Error
Er 030000 Load Profile Error
Discussion:
A Load Profile error occurs when the Load Profile parameter is out of range or inactive.
Full Scale Overflow
Er 100000
Error
Discussion:
A Full Scale overflow error exists when the calculated demand at an EOI exceeds the
register Full Scale value. The register Full Scale value is selected during programming.
If an overflow occurs, the error code Er 100000 is displayed in Normal mode. This error
is programmable to display during the one second display off-time or lock on the register
display.
The Full Scale overflow error displays when the overflow occurred. The Maximum
Demand register continues to accumulate and display kW as long as the format
limitations are not exceeded. When a demand reset is performed, the correct Max kW
value will be added to the cumulative registers and the error code will no longer be
displayed. If a Full Scale overflow occurs, check the installation to ensure that the
current metering capability has not been exceeded. A Full Scale overflow in no way
affects the existing billing data.

Fatal Error Codes

Code Error
Er 000004 Metrology Error
Discussion:
The direction of energy flow signal is monitored for rate of change. If the rate of change
exceeds 14 Hz, the metrology error is triggered. Under this condition the base metrology
has become defective and the energy pulse signal being sent from metrology to the
D/T/L module is no longer valid. Base metrology should be replaced in the event of this
error.
Er 000010 EEPROM Error
Discussion:
If the module has an EEPROM error, the error code ER 000010 will be continuously
displayed. If this error occurs, program the module and check for proper operation. If the
error continues to exist, replace the module.
Testing, Troubleshooting, and Maintenance
Table 8.3 Non-Fatal Error Codes
Possible Causes
Load Profile Error—Reprogram register and check for proper
operation; checked upon programming and once per second
Programmed Full Scale Value exceeded—Check programmed
Full-Scale value and meter installation for proper sizing of
equipment; checked continuously.
Table 8.4 Fatal Error Codes
Possible Causes
(Available in firmware revisions 10.27 and above.) Defective
component in the base metrology causing invalid energy pulse
signal.
Energy value checksum failure; EEPROM failure—reprogram
module and check for proper operation. If error still does not
clear, replace module; checked upon programming and at
power up.
