Symptoms

CAP operation fail.

SL8500 CAP procedure error with ACSLS auto CAP mode.

Intermittent CAP ejecting failure due to CAP procedure error.

ACSLS log shows it is assuming entering cart with CAP door opened and now library is enter mode even though ejecting cart.
ACSLS log shows:

Invalid Mode - 0 assuming ENTER.

ACSLS log indicated "Error: 0306 - CAP procedure error: CAP door is open" and "Invalid Mode - 0 assuming ENTER". Therefore we could consider operator error with their comments.

HBZ/HBC log show operator pressed CAP button to open CAP but ACSLS attempted to reserve CAP for EJECT before CAP was opened ,
With this behavior, ACLS assumed that operator attempted to enter....
Finally library CAP state was invalid...
(2hours and 10 minutes differed between ACSLS and Library)

Cause

ACSLS did not request CAP lock after reserve.
 

 

Solution

The following is correct order If operator enters carts to CAP for auto CAP mode.

CAP must be unlocked and released prior to Enter:
1) CAP button is pressed by Operator to open CAP
2) CAP door is opened
3) CAP is reserved by ACSLS
4) Cart(s) is(are) Entered by Operator
5) CAP button is pressed by Operator to close CAP
6) CAP door is physically closed
7) CAP is locked
8) Cart(s) move(s) to CELL for enter
9) CAP door closed status is sent to ACSLS by Library
10) CAP is unlocked by ACSLS
11) CAP is released by ACSLS

The following is ordered for enter from HBZ/HBC logs:
