F/B Encoder Error (cont.)
Faulty intermediate board / faulty
computer board
When replacing the computer
board note the software on the
defective board as well as the
position of the jumper JP1. Make
sure the software and jumper
postion are the same. Incorrect
software or jumper may cause the
machine to function improperly.
Set your multi-meter to DC Volts.
On the computer board,
connector J5 across pins 12 & 13
should be 5 volts. Across pins 13
& 14 should fluctuate between 0v
and 5v as you slide the robot front
/ back. If not replace the
intermediate board. PN-
49405540. If the pulse is seen
replace the computer board PN-
19300529.
Check connection from the
controller board to the U/D
encoder switch.
Turn power off. Check the
computer board connection
labeled J5, the intermediate board
connections J5 and J27 and the
plug at the up / down motor. If the
connections look good check
continuity from computer board J5
pins 9, 10 & 11 to int. board J5
pins 9, 10 & 11, and from int.
board J27 pins 2, 3 & 4 to the
front / back motor connector pins
2, 3 & 4.
Faulty encoder switch in the U/D
motor.
Set your multi-meter to DC Volts.
On the intermediate board,
connector J27 across pins 2 & 3
should be 5 volts. Across pins 3 &
4 should fluctuate between 0v and
5v as you slide the robot up and
down. If not replace the U/D
motor.
If the motor has a small pigtail
harness use PN-49505565. If the
connector is right on the motor
use PN-49505555.
