Safety Sensor 1 (SS1), Safety Sensor 2 (SS2)
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 switch contacts open. This
switch is interlocked with the power paper stacker 24 V system (actuator drive
system). When this switch is turned off, all motors are turned off, except the
elevator motor.
Elevator Keys (ESWA / ESWS / ESWD / ESWH)
These keys are used for operating the elevator.
•
Elevator AUTO Key (ESWA): This sets the elevator in automatic mode.
When this switch is pressed, the elevator first rises until the paper surface
sensor comes on, then lowers slightly and waits for paper to be
transported.
•
Elevator STOP Key (ESWS): This stops the elevator.
•
Elevator DOWN Key (ESWD): This lowers the elevator.
•
Elevator HEAVY Key (ESWH): This changes the paper mode (for thicker
or thinner paper).
