Emerson SecureStart User Manual

SecureStart™ module for Copeland™ compressors
Start-up performance and protection you can count on
technology to provide a safe and consistent start-up
for the compressor. By limiting the starting current
by up to 75%, compressor start characteristics are
improved and nuisances caused by current variations
are reduced. The SecureStart module delivers a new
level of protection and start-up consistency, provid
ing reliable system performance and longevity.

Why use the SecureStart module?
Upon start-up, electric motors consume large
amounts of current as they accelerate and build a
magnetic eld. Starting currents may reach ve to
eight times the levels of nominal operating currents
(see Figure 1). The SecureStart module dramatically
reduces the in-rush current and renders light icker
nearly imperceptible.
Additional benets
• Improved starting during low voltage conditions
• Compressor low voltage protection
• Compliance with certain local utility requirements
for reduced in-rush current
• Reduced stress and heating of compressor
• Can reduce the tonnage required in mobile power
generation
How it works
Once installed, the SecureStart module will detect and
reduce run winding current while adjusting the start
winding current to provide optimal starting torque. The
module provides an additional benet of continuously
monitoring supply voltage to prevent motor stalling
under low voltage conditions. When conditions such as
low supply voltage or locked rotor exist, the module will
switch off the motor, thereby protecting the compressor.
A delay function provides additional protection in the
event of an emergency shutdown.
SecureStart modules are designed for use with perma
nent split capacitor, single phase compressors with Rated
Load Amps (RLA) of 32 or less. SecureStart can be used
with Copeland compressors designed for pool heaters,
mobile power generators, or geothermal applications.
