Type MCI 15C, MCI 25C, MCI 50CM-3 I-O
[attachment=53251]
• Universal control voltage: 24 - 480 V ac/dc
• Automatic detection of missing phases
• LED Status indication.
• Automatic adaptation to 50/60 Hz
• Easy and quick installation
• Up to 12 start/stop operations per hour
• Built in varistor protection
• IP 20 Protection
• Compact modular design
• DIN rail mountable
• Ramp-time max. 0.5s (factory set-up)
• EN 60947-4-2
Description
The MCI compressor soft starters are designed
for soft starting of 3 phase compressors.
During start the MCI will gradually increase
the voltage to the motor until it reaches full
line voltage.
The soft start ramp-up time and initial start torque is
preset to ensure a fast start and allow easy and quick
installation.
MCI compressor soft starters are ideal for use on
Danfoss Performer scroll and Maneurop
Reciprocating compressors. The starting current can
be reduced by up to 40% of the direct on line value.
Mounting instructions
The controller is designed for vertical mounting.
If the controller is mounted horizontally the load
current must be reduced by 50%.
The controller needs no side clearance.
Clearance between two vertical mounted
controller must be minimum 80 mm (3.15”).
Clearance between controller and top and
bottom walls must be minimum 30 mm (1.2”).
Line controlled soft start
When the contactor C1 is switched to the
ON-state, the soft starter will start the motor, according
to the settings of the ramp-up time and
initial torque adjustments. When the contactor
C1 is switched to the OFF-state the motor will be
switched off instantaneously. In this application
the contactor will have no load during opertion.
The contactor will carry and break the nominal
motor current.
