User Manual R0.2
Normal:
It is defined for use in a way to give warning and fault other than the defined values such as screw
temperature sensor.
Difference:
The value measured by the second temperature sensor is subtracted from the value measured by the
first screw sensor, and error/warning conditions are created according to the difference value obtained.
P140 Press Comp.Temp. (Press Comp.Temp.)
If the value measured by the screw temperature sensor connected between terminal 7 and 8 is lower than the value
specified with this parameter, instead of "P002 switch to idle pressure", the compressor switches to idle according to
the new switch to idle pressure below.
Switch to Idle Pressure = P003 + (P002
–
P003)/4
P141 Oil Freeze Prevention Temperature (Oil Freeze Prvnt)
For parameter description see "Application note Oil freezing prevention"
2.2.7 Mains Parameters
P142 Mains Feed Unbalance Value % (Unbalance)
The parameter used to control the unbalance between the phases.
P143 Mains Feed Low-Voltage Fail (Volt Low Alarm)
If one of the mains voltage phases connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T”
is below the value specified with this parameter, the device indicates the relevant phase, switches to fault mode and
stops the motor. Fault delay is 1 second.
P144 Mains Feed Low-Voltage Warning (Volt Low Warn)
If one of the mains voltage phases connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T”
is below the value specified with this parameter, the device indicates the relevant phase and gives a warning. The
warning delay is 1 second.
P145 Mains Feed High-Voltage Fail (Volt High Alarm)
If one of the main
s voltage phases connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T”
is above the value specified with this parameter, the device indicates the relevant phase, switches to fault mode and
stops the motor. Fault delay is 1 second.
P146 Mains Feed High-Voltage Warning (Volt High Warn)
If one of the mains voltage phases connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T”
is above the value specified with this parameter, the device indicates the relevant phase and gives a warning. The
warning delay is 1 second.
P147 Mains Feed Low-Frequency Fail (Freq Low Alarm)
If the frequency of the mains voltage connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T” is below the value specified with this parameter, the device indicates a “Fre. Low Fault” message, goes into fault
mode and stops the motor. Fault delay is 3 second.
P148 Mains Feed Low-Frequency Warning (Freq Low Warn)
If the frequency of the mains voltage connected to the termi
nals “25
-24-
23” of the device, which are defined as “R
-S-
T” is below the value specified with this parameter, the device indicates a “Fre. Low Warning” message. The warning
delay is 3 second.
P149 Mains Feed High-Frequency Fail (Freq High Alarm)
If the fre
quency of the mains voltage connected to the terminals “25
-24-
23” of the device, which are defined as “R
-S-
T” is above the value specified with this parameter, the device indicates a “Fre. High Fault” message, goes into fault
mode and stops the motor. Fault delay is 3 second.
