!STOP Input (Pin 11)
The !STOP input is an active Lo input with an internal pull-up resistor.
The active-going edge of this input halts all Tester activity, turning off all signal
sources.
To use this with an ‘emergency stop’ switch, wire the switch between this input
and 0V.
Fail, Busy and Pass Outputs (Pins 4, 7 and 10)
The status outputs are standard 5 Volt logic signals.
In the standard set-up, the three status outputs are active Lo signals which
duplicate the three LED’s on the front panel - Busy, Pass and Fail. They
could, for example, be connected as status inputs to a robot controller, or a bin
selector.
Beep Output (Pin 1)
This is an active Hi output that copies the internal beeper.
It is configured in the test program header
(see the Test Editor section of this manual).
All the outputs (pins 1, 4, 7 and 10) are fitted with 1k
Ω
protection resistors, and
therefore they cannot directly drive external high current loads such as
indicators, or bin-select relays. Minimum input resistance of devices connected
to these outputs to be 10k
Ω
.
DO NOT USE (Pins 5, 8 and 9)
These pins are intended for use with Voltech approved accessories and must
be left unconnected.
DANGER: Pin 8 may have voltages of up to 500V present
during normal operation of the ATi.
