Screw Temperature High Fault (Temp1Upper Alarm)
Fault Definition:
Indicates that the value read by the Screw temperature sensor connected to terminals 7-8, which
are defined as AN2, is higher than the value entered to the "P122 Temperature 1 High 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.
Second Temperature High Warning (Temp2 Upper Warn)
Warning Definition:
Indicates that the value read by the secondary temperature sensor connected to terminals 3-4,
which are defined as AN4, is higher than the value entered to the "P135 Temperature 2 High 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 High Fault (Temp2Upper Alarm)
Fault Definition:
Indicates that the value read by the Screw temperature sensor connected to terminals 3-4, which
are defined as AN4, is higher than the value entered to the "P134 Temperature 2 High 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.
Screw Temperature Low Warning (Temp1 Down Warn)
Warning 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 "P125 Temperature 1 Low Warn" parameter. It is
just a warning message. Does not stop the motor.
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.
