Active Remote Control Status
UNIT ACTIVE REMOTE CONTROL = XXXXX
TYPE: RCC ISN CURR TEMP SOUND
This message indicates whether the system was operating
under Active Remote Control (RCC, ISN, LOAD, TEMP,
or SOUND) or standard control (NONE) at the time of
the fault.
UNIT SOUND LIMIT LOCAL = XXX %
ISN = XXX REMOTE = XXX %
This message indicates that sound limiting was in effect,
the amount, and whether it was local or remotely limited.
VSD Data
VSD Actual and Command Frequency
VSD FREQUENCY ACTUAL = XXX.X HZ
COMMAND = XXX.X HZ
This message indicates the VSD actual operating
frequency and the command frequency at the time of
the fault. Actual and command may not match due to
load/unload timers, limitation of 1 Hz per load/unload
increment, and to allowable acceleration/deceleration of
the motor.
Compressor Amps and %FLA
The message indicates the compressor %FLA and motor
currents for systems 1 and 2 at the time of the fault.
VSD COMP 1 = XXX AMPS = XXX %FLA
COMP 2 = XXX AMPS = XXX %FLA
VSD Current Limit
VSD CURRENT LIMIT LOCAL = XXX %
ISN = XXX REMOTE = XXX %
This message displays the current limit values as set
locally, by an ISN, or a remote current limiting input at
the time of the fault.
DC BUS Voltage
VSD DC BUS VOLTAGE = XXX VDC
This message displays the DC Bus voltage at the time of
the fault.
VSD Internal Ambient Temp and VSD Cooling
Status

COOLING SYSTEM STATUS = YYY
This message displays the VSD/Microprocessor internal
ambient cabinet temperature and the cooling system
status (ON or OFF) at the time of the fault.
IGBT Baseplate Temperature
VSD IGBT BASEPLATE TEMPS T1 = XXX.X °F
T2 = XXX.X °F
This message displays the IGBT highest baseplate
temperature at the time of the fault.
Precharge Signal Status
VSD PRECHARGE SIGNAL = OFF
This display provides the state of the precharge signal,
where XXX is either ON or OFF at the time of the fault.

Overload Current Setting
VSD COMP 1 MOTOR OVERLOAD = XXX AMPS
COMP 2 MOTOR OVERLOAD = XXX AMPS
This message displays the setting of the VSD’s 100%
FLA potentiometer for Compressor #1 and #2 at the time
of the fault.
System Data
System #1 Pressures
SYS 1 PRESSURES OIL = XXXX PSIG
DISCHARGE = XXXX PSIG
This message displays the measured system oil and
discharge pressures at the time of the fault.
