BL6-DU20PX series Integrated Door Motor Controller User Manual
2) Encoder signal lines should be placed separately from high voltage circuits to avoid
interference.
3) Encoder cable should better be directly connected to controller. If the cable is not long
enough and an extension cable is needed, the extension part should also be shielded and welded to
the original line of the encoder with soldering iron.
4) Encoder shielded layer should be well grounded in the controller side.

Grounding Check
Check the resistance between below terminals and PE terminal is infinite or not. If it is too
small, please check below immediately:
a) Between L1, L2 and PE;
b) Between U, V, W and PE;
c) Between 24V, PGA, PGB, PGZ, COM of encoder and PE.

a) In speed control mode, decreasing speed signal check.
Note: Recommended wiring: Connect DI1 to door-open slow down signal; Connect DI2 to
door-open limit signal; Connect DI3 to door-close slow down signal; Connect DI4 to door-close limit
signal.
Pull the door with hand, according to former chart, the correction of related signals can be
judged by corresponding LED status.
b) In distance mode:
Note: Recommended wiring for using limit switches. Connect DI1 to door-open limit signal;
connect DI4 to door-close limit signal.
Pull the door with hand in the direction of opening, if D2 is on, the phase-A & B signals are
normal, or else abnormal. Please exchange the A and B signal cables. Pull the door with hand in the
direction of closing, if the D2 is normal OFF, the phase-A & B signals are normal.
