The drive controller is directly linked to the controller. Faults in the drive controller will be displayed on the controller as "VSD fault 0, VSD fault 1" etc.
The following VSD faults may be investigated and remedied at source. For all other VSD faults, contact your local Ingersoll Rand customer support
representative.
80448517 Rev A
RELEASED 16/Dec/2014 10:49:53 GMT
CAUSE
Compressor operating above rated
pressure.
Low coolant level.
High ambient temperature.
Insufficient cooling air.
Dirty, blocked coolant cooler (cooling
air side).
Fan motor direction of rotation
incorrect.
Drive system fault.
Will occur if the fan or main motor
overload relays open for three seconds.
Fan is blocked, damaged or blower fan
is faulty.
Will occur the current transformers
indicate that the motor amp draw
is excessive. Trip only applicable for
compressors with current transformers
installed.
Remote start button is pressed after
compressor is running or remote start
button remains closed.
Remote stop button remains open and
either start button is pressed.
Sensor is missing or faulty
The compressor's variable speed drive is
reporting a fault.
Controller does not receive a response
from the VSD when requesting
information.
Controller is unable to properly setup
the drive after boot or after a reset.
Controller receives invalid
communications from VSD.
Occurs when compressor should be
stopped, but motor speed has not
dropped below minimum motor speed
set point for 4 seconds.
Emergency stop button has been
pressed.
Airend discharge temparature (2ATT)
is less than 35°F, and the operator
attempts to start compressor.
Will occur if 2ATT is greater than 103°C
This will occur if the compressor
VSD has not responded to the initial
communications from the controller.
REMEDY
Check and modify settings. Review system
requirements and contact your local Ingersoll Rand
representative.
Check for leaks. See also if discharge air is
contaminated with coolant. Top off coolant.
Review installation and system parameters.
Check ducting and cooling air path.
Clean or replace.
Wire correctly.
Contact your local Ingersoll Rand representative.
Remove blockage, repair or replace damaged
components.
R4-11kW units typically do not have current
transformers installed.
Check operation of buttons or operating procedures.
Check operation of buttons or operating procedures.
Install, repair or replace faulty sensor.
Refer to Table 6.
Contact your local Ingersoll Rand representative.
Contact your local Ingersoll Rand representative.
Refer to Table 6.
Usually indication that run delay (K1) did not open
when de-energized; due to this, the isolation contact
should open when this fault occurs. The isoaltion
contact can close when fault is cleared.
Identify reason why, repair fault, disengage button
and reset conroller.
Reset and start compressor if desired. Will be logged
that compressor is being used in low ambient
conditions.
Abnormal operating condition which is self-clearning.
Abnormal operating condition which is self-clearning.
