Sensor
Elevator I/O PWB Input 7
The book in Elevator sensor is a retro-reflective
sensor that detects books as they enter the Ele-
vator. The sensor is mounted near the bottom
of the Elevator, just above where books travel
into the Elevator (Figure 2-91). The reflector is
located on the Tilt Conveyor (Figure 2-92).
Possible Fault Indicators

“Elevator Book on Tilt Error”
is displayed erroneously.

A jam is not detected when there is a
jam.
Initial Actions
Check that the reflector is in place (Figure 2-92).
Replace if necessary (PL 5.41 Tilt Conveyor

Check that all cables between the trimmer, Ele-
vator, and Tilt Infeed Conveyor are securely fas-
tened and are not damaged.
Check and repair loose or damaged wires 59,
73, and 74 at the Elevator electrical panel.
