Use the HOST RUN INPUT when you want to monitor the RUN status of the
host. When this input terminal is enabled by pin 2 of DIP switch 1, then, if the
HOST RUN INPUT turns OFF, PT processing will be interrupted and a prior-
ity message will be displayed indicating that a host error has occurred. This
condition will be maintained until the host RUN status is restored.
Enable: Turn OFF SW1, pin 2.
Disable: Turn ON SW1, pin 2.
