When the HHT has verified that the HO_AVBL signal has turned
OFF, it prompts the operator to return the UUT to Automatic
Mode.
If the HO_AVBL signal does not turn back ON following the
switch into Automatic Mode, the operator should select the
Fail option to indicate that the test failed.
If the HHT detects that the HO_AVBL signal has turned ON, it
marks the test as Passed.

(Placement sensor(s) activated during Load, but
Presence sensor(s) is not).
Test M is implemented using a standard Load Cycle test. The
Load Cycle screen is displayed, and the HHT advances the
E84 handshake up to the point where the UUT is waiting for
the delivery of a FOUP.
At this point, the HHT prompts the operator to activate the
Placement sensor(s) only. The Placement sensors must
remain activated until the displayed count down timer
expires. At that point, the UUT should issue a TP3 timeout error.
If the UUT drops it’s L_REQ signal following the Placement
sensor activation, the HHT will fail the test. This indicates that
the UUT is accepting a mis-aligned FOUP delivery as a valid
handoff.
If the TP3 timeout occurs without the L_REQ signal dropping,
the HHT marks the test as passed.
