Emerson ES Serie Instructions De Service

Compressor Smart Starter ES-Series
General information and technical data:
Smart Starters of the ES-Series are used to limit start current and protect
Compressors. The start current is limited to 45 Amps. Smart Starters perform a
continuous compressor monitoring by measuring voltages and currents. In case of
overvoltage, overcurrent or undervoltage the system is switched off. To protect
the compressor, restarts are delayed by 3 minutes min.
Smart starters are released for use with many compressors. (See list Fig.3)
Do not use them with Digital Scroll compressors.
ESS-255 have been shipped with faston connectors until March 2006
ESC-255 are for connection with isolated fork connectors from April 2006.

Safety instructions:
• Read installation instructions thoroughly. Failure to comply can result in
device failure, system damage or personal injury.
• It is intended for use by persons having the appropriate knowledge and
skill.
• Unauthorised opening of the Smart Starter will void warranty.
• Switch off all voltages / currents before cabling.
• Comply with local electrical regulations when wiring
• Do not exceed operating temperature
• Do not operate system before all cable connections are completed.
Setting:
• No setting required. The Smart Starters automatically limit the start current
based on the connected compressor size.
Mounting:
• ES Smart Starters should be mounted in electrical switch board only. Use the
mounting clip. Protect ES from direct sun light and water.
Wiring:
• Perform wiring as printed on the housing. ES Contacts:
R Output motor run winding
RC Output run capacitor
L1 230V 50Hz power input
• Warning: Do not use an additional contactor. ES could be damaged.
• Warning: Do not connect the "RUN" capacitor C2 with the "Run" lead of the
motor. A start capacitor is built-in the Smart Starter.
• Incoming power lead (L1) and compressor run winding lead (R) should be
2
4mm .
• Run capacitor lead can be 2.5mm
Note: The current in this lead is < 10 amps.
• For the mechanical size of the fork crimp lugs see Fig. 2.
• The fork crimp lugs must be of isolated type
• The three screws are posidrive heads (not Philips). Use a # 2 size driver.
• The screws must be tightened with 3.0... 3.5 Nm.

• Note: The "RC" output can be used to switch the condenser fan.
Operation
• After all connections are wired, supply voltage can be switched on. The motor
will start with limited start current, when contact "ON" is connected to 230V
(for min. 0.5 sec). The Smart Starter monitors the start sequence.
• If the motor does not start (e.g. locked rotor) it is switched-off by Smart Starter
latest after 0.8 sec. For compressor protection a restart is delayed by 5 Minutes.
• The compressor is switched-off, when "ON" is disconnected from 230V. A
restart is delayed by 3 Minutes. After this time a start is possible immediately.
• The LED is indicating following operating conditions:
Ready to accept a start command:
3 minute cycle delay:
Fault mode:
Low voltage:
Standards
• Electro magnetic compatibility
• Low voltage directive
• Safety and environmental requirements for refrigeration systems and heat
pumps
• Contactors and motor-starters - AC semiconductor motor controllers and
starters
