7.1 Signal Output
The rear panel connector of the 400XAC Series provides output signals to
remotely monitor PASS, FAIL, and PROCESSING conditions via a 9-Pin D-type
connector. When a terminal becomes active the relay closes thereby allowing

the conditions of each pin and the relay state.

the buzzer will beep twice before returning to the RESET condition, when any
key on the front panel is pressed. Whenever there is an abnormal output
