Single Phase Soft Starters
Page 11
Flash Code (Slow Flash (1 / 3 secs): Lockout on
Over current)
- Displayed for “Overcurrent” in running mode of the
compressor motor.
- Overcurrent limit is “25A for 08-16A version” and
“50A for 16-32A rated version”.
- Also displayed, if internal Klixon of the compressor
trips out on overheat.
- Re-start is attempted after 10 minutes.
To limit the current in compressors from extending
abnormally beyond its stated capacities, SureStart is
also equipped with Overcurrent limit protection. For
models rated from 16-32A, SureStart is designed to trip
out in overload conditions exceeding 50A. In smaller
models, it is designed to cutoff power to the compressor
if the current drawn exceeds 25A. On overcurrent
lockout, SureStart attempts a re-start automatically
after 10 minutes.
Both failed start lockout and overcurrent limit
protection have been designed to prevent the
compressor from drawing abnormal currents in
conditions not feasible for the compressor operation.
Flash Code (Slow Steady Flash (1 / sec): Cycle
Delay / Fault Mode)
- 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
- incorrect wiring during installation,
- a failed Softstart attempt,
- intermittent power loss (duration longer
than 100ms),
- frequency out of range, or
- failed run capacitor.
