Flash Codes
– Three Phase
A Red LED indicator will flash under the following conditions. [NOTE: LED fault indicator is turned
off in normal running mode.]
a) Reverse Phase: (1 / 2 secs)
b) Fault Mode/Cycle Delay: (1 / 4 secs)
c) Low Voltage/Over Voltage: 2 / 2 secs)
Flash Code (Reverse Phase: (1 / 2 secs))
- Displayed
if the supply “Phase Sequence” gets reversed before or after a start.
- Re-start is attempted after 3 minutes.
Flash Code (Fault Mode / Cycle Delay: (1 / 4 secs))
-
Displayed for “Cycle delay” between two consecutive softstarts or other faults mentioned
below.
- Re-start is attempted after a default period of 3 minutes.
- Other possible reasons for this Fault mode indicator can be due to
- a failed Softstart attempt,
- intermittent power loss (duration longer than 100ms),
- frequency out of range
Flash Code (Low Voltage / Over Voltage: (2 / 2 secs))
-
Displayed for “Low supply voltage” or “High supply voltage” before or after a softstart.
- If voltage is out of range before a start, a re-start is attempted after 50 seconds.
- If voltage is out of range after a start, a re-start is attempted after 3 minutes.
