4.3.4 Additional Emergency Off (EMO) input

In addition to the emergency off button, which stops the pump and interrupts all
primary voltage outside the main control panel, pump has a connector for an
"emergency" signal input. The user may place this connector in any external
interlock circuit (e.g. scrubber failure, gas leak detection, EMO "daisy chain").
Any break in this external circuit will shut down the pump.
Additional EMO input connector "EXT. IO" is located on front panel. Refer to
outline drawing shown in section 3.5. (Near signal connector port.)
CAUTION Dummy plug should be connected on "EXT.IO" receptacle
