No Vertical (Y) and No Horizontal (X) Movement
There are only a few reasons the Peripheral Boards will not send power to both the X and Y Motors at the
same time.
1. Check for Cabinet Control Board Errors “C Comms” when first entering programming with 3333.
2. A Motor Power Interrupt Switch (left switch in bracket) issue:
a. Check Top Circuit Breaker that it hasn’t disengaged, reset if necessary.
b. Check the wiring from the Motor Power Interrupt Switch to the Red/Blue Wire in Pin 4 of the
AC Distribution Box 24 pin connector & the Red/Green Wire in Pin 5 of 24 pin connector of the
Environmental Board. With the Motor Power Interrupt Switch engaged, Ohm the wires, there
should be continuity. If not:
1) Check the Red/Blue Wire.
2) Check the Red/Green Wire.
3) Replace the Motor Power Interrupt Switch.
c. If the Motor Power Interrupt Switch passes, check the Red/Blue Wire in Pin 4 of P1 Connection
of the Environmental Board to ground for 24VDC to the Motor Power Interrupt Switch from the
Environmental Board.
d. If 24VAC is not present, check for continuity of the Red/Yellow Wire from the OMRON Power
Supply to the Red/Blue Wire in Pin 4 of P1 Connection of the Environmental Board. If there is
not continuity check:
1) Top 3A Circuit Breaker of AC Box Assembly
2) Replace Environmental Board
3) Replace OMRON Power Supply
3. A Picker error:
a. Before replacing any Control Boards, remove the Cup Cover:
1) Ohm the RS485 Communication Wiring from the Cup Motor Board to the Y Motor
Board.
a) Check the Blue Wire in Pin 3 of P2 Connection of the Cup Motor Board has
Continuity to Pin 5 of P4 Connection of the Y Motor Board.
b) Check the White Wire in Pin 4 of P2 Connection of the Cup Motor Board has
Continuity to Pin 3 of P4 Connection of the Y Motor Board.
2) If there is not continuity at 1a) and 1b) check:
a) Check for continuity of the Yellow, Blue and White in the Cup Harness (400505),
replace as necessary.
b) Check for continuity of the Yellow, Blue and White in the in the Y E-Chain
Harness (400504), replace as necessary.
3) Check the Yellow Wire in Pin 1 of P2 Connection of the Cup Motor Board to ground.
There should be 5VDC.
b. Ensure the Cup Motor Board Green Status Light is flashing rapidly. If there is a 2 flash and
pause the RS485 Circuit is open:
a. Check the P1 Connection on the RS485 Interface Board is plugged in.
b. Check the J30 Cab Comm of the RS485 Interface Board Connection on the Atlas H
Board.
c. Check the Blue Wire connection from the Pin 3 of the P1 Connection of the RS485
Interface Board to the double Blue Wire in Pin 23 of P1 Connection of the
Environmental Board.
