Electron AC Starter OLP 3+ User Manual

230
Thank you for choosing an Electron product!
The all-new OLP 3+ is an advanced microprocessor-controlled motor starter designed to ensure
safety and long life of your air-conditioner using the time-tested combination of VOLT CHECK,
AMP CHECK, and TIME CHECK. The vivid 3-digit display shows all operational parameters
such as voltage, current, reason for trip, and time remaining till reset, for user interest and
awareness of their AC's consumption characteristics. OLP 3+ coveniently fits in a standard 4-
module box.
VOLT CHECK - OLP 3+ monitors the line voltage and
trips if safe limits (160-270V) are breached. If tripped,
the reason (Hi/Lo) and value of unsafe voltage are
shown.
AMP CHECK – Current drawn by the AC is monitored
continuously, and the output is disconnected if this
exceeds a pre-set limit. This protects the compressor
from damage due to rotor locking or excessively long
start-up time. Tripping follows an inverse time-current
characteristic - higher the overload, faster the tripping
response. After tripping, the overload current is shown
on the display.
TIME CHECK – On tripping, OLP 3+ holds the output
open for a duration of 3 minutes from the time of last
compressor operation, and then restarts the AC
automatically. This is important safety measure for the
compressor. When TIME CHECK is active, the display
indicates the number of minutes left for AC to restart,
along with trip information.
