Drive arrangement
On ARR E, the motor is flanged to the gear casing by means of a coupling housing. The motor/gear casing
unit is supported on the frame by vibration dampers.
On ARR 1, the motor is mounted on a separate subframe. The subframe and gear casing are supported on
the frame by vibration dampers.
Elektronikon control system
The compressor is controlled by an electronic regulator which:
• Controls the operation of the compressor
• Reduces the power consumption
• Warns the operator in case of an abnormal operating condition
• Protects the compressor
• Monitors components subject to service
• If activated, the regulator can automatically restart the compressor after voltage failure
Optional equipment
Following equipment is available as an option:
Full-Feature
The compressor is additionally provided with an IMD adsoption dryer. The dryer is integrated in the
bodywork and removes moisture from the compressed air.
Connections
This compressor can be provided on the compressed air outlet and water pipes with:
ANSI flanges
DIN flanges
DIN flanges + DIN to JIS adapter flanges
Separate air intake
This compressor is prepared to install separate ducting for cooling air flow and compressed air flow.
Motor temperature protection
Temperature sensors (PT1000) are embedded in the drive motor to warn the operator if the temperature
becomes too high and to shut down the compressor, thereby protecting the motor from overheating.
Motor bearing temperature protection
Temperature sensors (PT1000) are embedded in the drive motor to warn the operator if the temperature of
the bearings becomes too high and to shut down the compressor, thereby protecting the motor bearings
from overheating.
