Limit Switch Wiring

Motors must be wired to include the limit switches in the motor to terminate operation and prevent damage
to a structure in the event the motors are over-run.
The MX3 will not operate the motor relays unless the limit switches are properly connected or terminals jumpered
unless the inputs are inverted as described below.

Limit switch inputs operate using the DC input voltage (12-24Vdc) supplied to the switch and returned to
the input terminal.

limit is met. The MX3 can be confi gured to operate in the opposite manner with the limit switches in the
Normally Open position during normal operation and Closed when the limit is met.
