Table 7.03: List of Warnings and description.
Output Switch circuit breaker is detected as being racked out
from its cubicle.
Output switch circuit breaker relay warning.
Output switch circuit breaker relay fault is detected.
Automatic Bypass switch circuit breaker reports as ready to
transition before software thinks it should.
Automatic Bypass switch circuit breaker is detected as being
racked out from its cubicle.
Automatic Bypass switch circuit breaker relay warning.
Automatic Bypass switch circuit breaker relay fault is de-
tected.
In the Automatic Bypass switch, there has been a mismatch
detected between "open" request and "open" Feedback.
The output current loading on the system exceeds system
nominal rated current by more than a certain percentage.
The system output current has been detected as exceeding
the maximum allowable.
The RMS value of output line voltage has fallen below the low
voltage threshold value.
Demand Response Power Controller communications link not
valid.
Demand Response Power Controller has determined state of
charge of energy storage is at minimum or maximum limit.
Energy Storage enclosure MODBUS INPUTS & OUTPUTS NOT
VALID.
MVM enclosure MODBUS INPUTS & OUTPUTS NOT VALID.
Possible power supply issue or malfunction in APS enclosure.
Possible power supply issue, Ethernet cable fault, Modbus
software malfunction in APS enclosure.
Feedback signal from one of buffer PSU (APS or PE120 enclo-
sure) indicates POWER SUPPLY FAILURE TO CHARGE within a
specified charging period.
One or more MCBs in APS enclosure are OPENED or TRIPPED.
Possible power supply issue, Ethernet cable fault, Modbus
software malfunction in MVM enclosure.
The APS enclosure temperature is measured as HIGHER THAN
A PRESET LEVEL. This indicates COMPROMISED COOLING.
The resistance of DC conductors is LOWER than the defined
limit.
There is a communication problem between the Demand Re-
sponse Power Controller and the MV UPS.
The Demand Response Controller is LIMITING STATE OF
CHARGE of the Energy Storage.
There is a communication problem between the Energy Stor-
age and the MV UPS.
