CAUTION
To prevent possible injury or equipment damage, BEFORE APPLYING POWER af-
ter the Executive PCBA is replaced, MAKE SURE THE CABINETDOOR IS OPEN.
When power is applied to the TLS while the cabinet door is open, no TLS motors
will operate. The configuration information in the new Executive PCBA must be
updated to match the library’s installed hardware, BEFORE any TLS motors are al-
lowed to operate.
1.
Make sure that the cabinet door is open
, then reconnect the power cord and turn
on the TLS power.
NOTE
Both the +12V and +5V LEDs at the top of the Executive board must light.
Confirm that the Front Panel display lights and that characters are displayed.
2.
Inspect the label on the rear-panel to determine the unit’s model number.
NOTE
If the TLS was upgraded in the field to a larger model, the rear-panel label may not indicate the
correct, current model number.
