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.
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.
34
