Fault Definition: Indicates that the value read by the Screw temperature sensor connected to terminals 7-8, which
are defined as AN2, is lower than the value entered to the "P124 Temperature 1 Low Alarm" parameter. It is a
malfunction that stops the compressor rapidly.
Possible Causes and required actions: Incorrect sensor may have been selected. Incorrect sensor type may have
been selected. The value that is entered to the parameter may have been wrong for the application.
Second Temperature Low Warning (Temp2 Down Warn)
Warning Definition: Indicates that the value read by the secondary temperature sensor connected to terminals 3-4,
which are defined as AN4, is lower than the value entered to the "P137 Temperature 2 Low Warn" parameter. It is
just a warning message. Does not stop the motor.
Possible Causes and required actions: There may be a problem that causes the temperature to increase. Incorrect
sensor may have been selected. Incorrect sensor type may have been selected. The value that is entered to the
parameter may have been wrong for the application.
Second Temperature Low Fault (Temp2 Down Alarm)
Fault Definition: Indicates that the value read by the Screw temperature sensor connected to terminals 3-4, which
are defined as AN4, is lower than the value entered to the "P136 Temperature 2 Low Alarm" parameter. It is a
malfunction that stops the compressor rapidly.
Possible Causes and required actions: There may be a problem that causes the temperature to increase. Incorrect
sensor may have been selected. Incorrect sensor type may have been selected. The value that is entered to the
parameter may have been wrong for the application.
R Phase Voltage High Warning (Vr High Warn)
Warning Definition: Indicates that the R Phase Voltage connected to the terminal “25”, which is defined as “R”, is
higher than the value entered to the “P146 Mains Voltage High Warn” parameter. It is just a warning message. Does
not stop the motor.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
R Phase Voltage High Fault (Vr High Alarm)
Fault Definition: Indicates that the R Phase Voltage connected to the terminal “25”, which is defined as “R”, is higher
than the value entered to the “P145 Mains Voltage High Alarm” parameter. It is a malfunction that stops the
compressor rapidly.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
