Safety Sensors 1/2 (Ss1/2; Elevator Keys (Eswa / Esws / Eswd - Printronix L5000 Series Maintenance Manual

Safety sensors 1/2 (SS1/2)

These are safety switches in case the operator accidentally gets his hand caught
between the frame and elevator table of the power stacker. When this happens, the
bar inside the cover tilts, and the contact point opens. This switch is interlocked with
the power stacker 24V system (actuator drive system). When this switch is turned
off, all motors except for the elevator motor are turned off.

Elevator keys (ESWA / ESWS / ESWD)

These keys are used for operating the elevator.
ELEVATOR AUTO KEY (ESWA): This sets the elevator in auto mode. When
this switch is pressed, the elevator first rises until the paper surface sensor comes
on, then lowers a bit, and waits for paper to be transported.
ELEVATOR STOP KEY (ESWS): This stops the elevator.
ELEVATOR DOWN KEY (ESWD): This lowers the elevator.
HEAVY KEY (version 2 only): This changes the paper mode (for thicker or
thinner paper).
