ADDITIONAL ENCODER
If an additional encoder has been specied there will be a third cable that should be connected to the relevant
encoder input on the drive amplier used. When used with the Copley Xenus (XTL-S) or Xenus (XSJ-S) an adaptor
cable is supplied.
Connections are available via a 9-way D-sub male connector.

LIMIT SWITCHES
WARNING. These limit switches are not intended as safety devices or as part of a system
intended to ensure personal safety. When two switches are mounted in close proximity (as
in the case of a left and right limit switch), a minimum of 30mm spacing between sense areas
must be maintained.
If limit switches have been specied there will be an additional cable per limit switch. These should be connected
to the relevent I/O on the drive amplier.
The output for all types can be normally closed (NC) or normally open (NO) open collector transistor. The NC
ouptuts switch open when a limit is detected and current stops owing in the LOAD. The NO ouputs switch closed
when a limit is detected and current starts owing in the LOAD.
A red indicator shows when a limit is detected.
OVER-TEMPERATURE SENSOR
CAUTION. It is strongly recommended that the forcer over-temperature sensor is connected
to the drive amplier or servo controller at all times in order to reduce the risk of damage to
the forcer due to excessive temperatures.
