T144 - I/E Station Door Sensor Stuck
Description
GUI Description:
An I/E (or I/O) station sensor switch is reporting incorrect
sensor status and may be stuck.
Explanation:
The library controller detected that an I/E station sensor is not
reporting a valid status. The problem may be caused by a stuck sensor in the
I/E station lock assembly with a control module or expansion module. Door
open and close state changes are not detected reliably, and premature I/E
station teach operations may occur, or no teach and inventory operation may
be triggered at all.
Detection Scenarios
When processing a state change on either of the two sensor switches, if the
sensor switch causing the interrupt is activated, the opposite sensor switch is
checked to see if it is activated too. If they are both active, one sensor switch
is stuck.
Root Causes
• A sensor switch is obstructed by foreign material.
• A sensor switch is binding or sticking.
• A sensor switch is broken.
