User Manual R0.2
Possible Causes and required actions:
There may be a signal coming to the terminal to which the backup fault 2
function is assigned. Contact type may be wrong. Check that the terminal of the contact of equipment connected to
the terminal to which the relevant fault is assigned is correctly connected and that the signal is transferred from
terminals 11 and 15 to the corresponding input when the contact is closed.
1.6.2 Analog Input Faults
Analog inputs define the inputs connected to terminals 3-10, which are defined as AN4, AN3, AN2, AN1; and
terminals 22-25, which are defined as N, T, S, R. Relevant inputs are shown in the diagram below. You can see the
same diagram on the label on the back of the device.
Phase Sequence Error Analog (Phase Seq - AI)
Fault Definition:
Indicates that the sequence of the 3-phase voltage connected to the terminals 22,23,24 and 25 of
the device, which are defined as N, T, S, R, is incorrect. It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
Phases connected to the R-S-T terminals of the device may have been
connected incorrectly. There may be a problem with the cable connection. Enter the Phase Voltages screen on the
information screen of the device and check whether there is an unbalance in the voltage values.
Line Sensor Error (Line Sens Alarm)
Fault Definition:
Indicates that there is a problem in the connection of line pressure sensor that is connected to the
terminals 9-10 of the device, which are defined as AN1. It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
The line pressure sensor connected to the relevant terminal may be defective
or there may be a problem in the cable connections.
Screw Sensor error (Screw Sens Alarm)
Fault Definition:
Indicates that there is a problem in the connection of screw pressure sensor that is connected to
the terminals 5-6 of the device, which are defined as AN3. It is a malfunction that stops the compressor rapidly.
