Table 11 - System Event Table
Event Code Code Name Full Name Severity Area Event Description Event Resolution
1 POWER_ON DySC Power On Informational Unit Power re-applied to the DySC. No action needed.
4 T_FAN_ST Fan Test Start Informational Unit Start acknowledgment of DySC fan test. No action needed.
5 T_IN_ST_1 Inverter Test (.5 cycles) Start Informational Unit
Start acknowledgment of DySC 0.5 cycle
inverter test.
No action needed.
6 T_IN_ST_2 Inverter Test (3 cycles) Start Informational Unit
Start acknowledgment of DySC 3 cycle inverter
test.
No action needed.
7 T_IN_ST_3 Inverter Test (5.5 seconds) Start Informational Unit
Start acknowledgment of DySC 5.5 second
inverter test.
No action needed.
9 EXTERNAL External Inhibit Auto-Resetting Inverter
Controller is inhibited by another phase
controller.
Review event details from other phase controllers.
11 RUN_TO Inverter Run Timeout Auto-Resetting Inverter
DySC inverter had a total cumulative runtime of
more than rated.
No action needed.
12 LIM_CYCLE Inverter Limit Cycle Timeout Auto-Resetting Inverter
Power was re-applied more than once within a
58 second period.
No action needed.
13 STAT_OT Static Switch Over-Temperature User Attention
Static
Switch Static switch heatsink temperature was greater
than maximum rating.
Verify ambient temperature is within DySC
specification. Check for damaged fans. Check for
dirty or obstructed air filters.
14 OVERLOAD Overload User Attention Unit
Inverter inhibited because load current
exceeded maximum rating. Reduce load. In parallel DySC systems, verify proper
current sharing among slave cabinets.
15 DC_OV DC Bus Over-Voltage User Attention Inverter
Positive or negative half of DC bus voltage
exceeded maximum rating. Verify line voltage is within ratings. Verify proper
DySC application. Call service.
16 CNTRL_UV Controller Power Under-Voltage User Attention Inverter DySC control power supply is out of tolerance.
Verify DySC is online and line voltage is within
ratings. Call service.
17 OUTPUT_UV Output Under-Voltage User Attention Inverter
DySC output voltage was less than 80% of
nominal during sag correction. Sag condition
likely outside of DySC specification.
Verify line voltage is within ratings. Verify proper
DySC application.
18 INV_OC Inverter Over-Current User Attention Inverter
Inverter current exceeded maximum rating
during sag correction.
Verify load current is within ratings. Verify
mechanical bypass switch is open. Verify proper
DySC application.
19 DC_UV DC Bus Under-Voltage User Attention Inverter DC bus voltage below operational range. Verify line voltage is within ratings. Call service.
20 OUTPUT_OV Output Over-Voltage Call Service Inverter
DySC output voltage was greater than 115% of
nominal during sag correction.
Call service.
22 IGBT IGBT Pack User Attention Inverter
IGBT pack reported error. Possible sag condition
outside of DySC specification. Verify line voltage is within ratings. Verify proper
DySC application. Call Service.
25 SYNC_ERR Line Synchronization Error Call Service Inverter
Inverter not synchronized to line when sag
detected.
Call service.
31 CONFIG Configuration Alert Call Service Inverter Controller configuration has changed. Call service.
32 CNTRL_MEM Controller Memory Busy Auto-Resetting Inverter
Controller is loading new data into Flash
memory.
No action needed.
33 UNBALANCE Start-Up Test: DC Bus Unbalance Call Service Inverter
Positive and negative halves of the DC bus did
not charge equally during power up.
Call service.
