Swisslog Nexus - Instruction details and expected conditions

SEQUENCE FOR TROUBLESHOOTING NEXUS STATION COMPONENT ERRORS | INSTRUCTION DETAILS AND EXPECTED CONDITIONS 74
APR/2017 TECHNICAL OPERATIONS AND MAINTENANCE GUIDE | NEXUS STATION
 Inspect the power source for the affected component at the main circuit board. See the illustra-
tion for help locating the position of each power source.
 Inspect the motor and connected harnesses that control the movement of the component.
 Inspect other affected cables and/or harnesses for possible damage or disconnection, and verify
that they are connected securely at both the circuit board and the component and/or motor.
 Run the Station Diagnostics procedure for the affected component.
 Verify that the signal to the affected component is being sent and/or received at the main circuit
board. See the illustration for help locating the position of the LEDs that correspond with the
affected signal.
Instruction details and expected conditions
Follow the applicable procedures in this list to troubleshoot problems occurring with Nexus Station compo-
nents. The table also provides descriptions of expected conditions of each of the troubleshooting actions.
Following the tables outlining troubleshooting procedures for each component are photos to help you
locate the assemblies and sub-assemblies related to the affected component. Refer to the separate compo-
nent instructions for details that are specific to troubleshooting that component. Complete the actions that
apply to the component you are troubleshooting.
To investigate the cause of most of these errors, begin by removing the main door, and turn off the sta-
tion at the power switch. See Outer door
.
CAUTION! To avoid electrical shock, turn off the station at the power source before beginning
any inspection of the interior components of the Nexus Station. Turn on power to the station
when you are ready to run the diagnostic procedures from the station control panel.
TABLE 1. Troubleshooting sequence for Nexus Station component errors
Action Details | expected condition | next steps
1 Inspect the affected component, motor,
and surrounding area.
Component, motor, and surrounding area are intact and undam-
aged.
 If the component appears to be damaged, replace it if possi-
ble.
 If there appears to be damage to the surrounding area (rails,
cogs, gears, or other related components), repair or replace
them as necessary.
2Check for any physical debris or other
impediments that could interfere with the
movement of the affected component
Component and connected moving parts are free of debris or
foreign objects that could be impeding their movement.
 Carefully remove any debris or foreign objects that may be
interfering with the movement of the part or parts being
investigated.
3 Inspect the component’s power source at
the main circuit board.
Harness ends are securely connected at the proper termination
point. “P” number on the harness matches the “J” number on the
board. Wire and conduit are continuous and not detached, cut
or frayed.
 Connect harnesses securely if they are not connected or if all
pins are not properly aligned within the connector.
 Replace the power harness if it is damaged.
