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

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
