detect sensor that controls Gate 9 is on the main track at the
output of the large disk. Gate 9 is activated to stop carriers on the
Workcell Main Track and prevent collision with On-line carriers
leaving the IM.
On-line carriers released by G5 are routed around the large disk
to the Main track by opening the D2a (Lane 3/1) and closing the
D3 (Lane 4/Track) diverters. As the carrier passes the D3 diverter,
it is detected by the optical carrier detector and gate G9 is closed
to prevent a collision.
Diverters Description
Diverter Gates (D0-D1-D2a-D2b-D3) – These gates are used to
route a carrier into a different lane. The IM has five Diverter
Gates named D0, D1, D2a, D2b and D3. The diverters D1, D2a,
D2b and D3 are unique to i2000SR IM and have a different design
than those used on the main track. They are driven by the F/W
and used to control the routing carriers to the final destination.
Below is a description of each diverter and its function in
association with a gate.
D0 – Standard Track Diverter – is located at Gate G0 and is
activated by EV2 to divert tubes from the main track that are to
be processed by the i2000SR. The carriers bypass the i2000SR as
the diverter is normally in the open position.

D1 – Lane 3/2 Diverter – is located at Gate G7b and is activated by
EV15 and has two functions 1) In the inactivated state, carriers
with sample tubes are released from Routine Input Gate G7b
where they are diverted from Lane 3 to Lane 2. 2) When Priority
Carriers are used, D1 is activated to allow carriers to continue to
move along Lane 3 to the Priority Input gate queue. The carriers
are diverted to Lane 2 as the diverter is normally open.
