•
Make sure that the contact type of the input to which the digital fault is assigned is defined correctly.
•
Make sure that there is no problem in the wiring between the terminal of the corresponding output and the
terminals 11 and 15 of the device.
•
Make sure that the equipment connected to the corresponding output is working properly.
•
Check that the + 15V signal coming out from the terminals 11 and 15 of the device is not short-circuited to
another signal with a faulty connection.
Important note:
It is recommended that the function parameters of the unused inputs of the device are selected as
"None" and the Contact Type parameters are selected as "NO" normally open.
Emergency Stop (Emergency Stop)
Fault Definition:
It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
The emergency stop button may have been pressed. Contact type may be
wrong. Check that the terminal of the Emergency stop button is correctly connected to terminal “DI1” 12, which is
the default input, and that the signal is transferred from terminals 11 and 15 to the corresponding input when the
contact is closed.
Separator Filter (Separator Filter)
Fault Definition:
It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
Filter sensor contact may have been activated due to a clogging on the
separator. The sensor may be malfunctioning. Contact type may be wrong. Check that the terminal of the separator
filter contact terminal is correctly connected to terminal “DI3” 14, which is the defa
ult input, and that the signal is
transferred from terminals 11 and 15 to the corresponding input when the contact is closed.
Oil Pressure (Oil Pressure)
Fault Definition:
It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
The sensor contact may have been activated due to low oil pressure level. The
sensor may be malfunctioning. Contact type may be wrong. Check that the terminal of the oil pressure contact
terminal is correctly connected to terminal “DI5” 17, which is the default input, and that the signal is transferred
from terminals 11 and 15 to the corresponding input when the contact is closed.

DI (Phase Seq
–
AI)
Fault Definition:
It is a malfunction that stops the compressor rapidly.
Possible Causes and required actions:
Motor phases may be connected incorrectly. The contact of the phase
sequence relay may have been activated. Contact type may be wrong. Phase sequence relay may have
