INSTRUCTIONS AND DIAGRAMS FOR THE REPLACEMENT OF THE CODE 140 CARD WITH THE CODE 390S
CARD
When installing the code 390S in the place of the code 140, the tachometric inversion contact is eliminated.
The ramp zeroing contact (AR), if used, should be moved to terminal 5 of the code 390S, the positive of the turn adjustment
potentiometer (P+) should be moved to terminal 6 of the code 390, and the negative of the auxiliary terminal board
should be connected to terminal 7 of the code 390S. The deceleration contact (DEC) should be moved to terminal 4 of
the code 390S, the positive of the code 140 couple adjustment terminal should be moved to terminal 8 of the code 390S
(in this case micro S9 should be closed on the 390S card), and the negative moved to terminal 7.
The connection exchange is highlighted by the circled numbers in the diagrams below – follow these numbers for power
connections also.
The supply line (U V W on the code 140) should be moved to terminals R1 – S1 – T1 of the code 390S. The outputs for
the motor (Z X Y for the code 140) should be moved to terminals U1 – V1 – W1 of the code 390S. The three wires (U V
W) which previously went to the motor should be removed and the motor should be delta connected.
Set the micros on the code 390S card as follows:
S1 – S5 – S6 – S8 – S10 – S11 – S12 Closed
S4 – S7 – S9 Open
S2 – S3 see instructions
